14 Assessment Conclusion and Suggestions14.1 Role and significance of the construction of the Two Roads and One BridgeThe project of Nanjiang Binlu starts from the south flyover of Cangqian Road of Minjiang Bridge in Sanxian Overslaugh, and goes by the Liberation Bridge, Minjiang Bridge II, Minjiang Bridge III, and the planned Qianheng Bridge. The Nanjiang Binlu is the north ring road of Nantaidao Road, a backbone road connecting the old city area of Cangshan district and the new city area of Chengmen district, and an important component of the ring road of Nantaidao Road. It is a road along the river integrating functions of recreation, sight-seeing and transportation. The 3rd Ring Road locates in the south of the island, starting from Wanbian in the west, and stopping at the south end of the planned Kuiqi Bridge across Minjiang River. It goes across Nantaidao Island from the southwest to the northeast, forming a high-speed passage connecting the downtown area with the University City, Jinshan district (newly built) and Gaishan district. As the south ring of the 3rd Ring Road, the project plays a key role in the construction and development of Nantaidao Island. Kuiqi Bridge is a key project in planning the east section of the 3rd Ring Road across the Minjiang River. The construction of a bridge over the river in the down stream of Minjiang River largely shortens the distance between the south and the north. The communication thus becomes more convenient and expedite. At the same time, the project is connected with the expressway to the airport, therefore, makes Changle International Airport and the area along the airport expressway nearer to the downtown area and increases the east exiting channel of Fuzhou city. What’s more, the construction of the project not only completes the expressway of the 3rd Ring Road, but also largely promotes the networks construction along the 3rd Ring Road and consummates the networks structure in the urban area of Fuzhou. The construction of Nanjiang Binlu, the Phase-II Project of the Third Ring Road and Kuiqi Bridge is beneficial to the land exploitation and construction of the new city areas, and to the promotion of the city development via communications. What’s more, it plays a significant role in promoting the development and construction of Cangshan District and the whole Nantaidao Island, improving the investment environment, promoting the development of the city economy and exerting the function of Fuzhou as the provincial capital and center. 14.2 Assessment and Protective Measures of Ecological Environment14.2.1 Ecological Environment(1) Current situation of land ecological environment Most districts along Nanjiang Binlu have been built. There are so many banyan trees, mangos, and Bauhinia variegata etc along Cangqian Road. In other place, there are mainly demolishing housings and only few trees. There are many tangerine gardens along the Phase-II Project of the Third Ring Road and a few farmlands and vegetable lands. There are banana lands, longan lands and pomegranate lands in the farmlands. There is plantation wood of acacia, masson pines and banyan trees, which is flourishing, on Aoshan Mountain (Duyuan Mountain), where there are several wide trees. There are farmlands beside the two sides of south elevated viaduct of Kuiqi Bridge; there are mainly demolishing housings and few trees beside the north overpass. (2) Post-nesting migrations of fishes and crabs and situations of farms of lower reach (including Kuiqi lower river) of Minjiang River. 1) Post-nesting migrations of fishes and crabs in lower reach of Minjiang River. ① Eel. Eels are affected during the period from November till March of the next year. Mature eels move from the freshwater to the ocean to lay eggs, incubate and then young eels come into being. Young eels move back to the freshwater to live from the ocean. According to record, there are about 2-3 tons of young ells captured at the estuary of Minjiang River. ② Mitten Crab. They concentrate during the period from November to December and May to June each year. In October of each year, Mitten Crabs move from the freshwater to the ocean to propagate, mainly during the period from November till December. After oviposition, incubation and then young crabs will come into being, they move back to the freshwater from the ocean, mainly during the period from May till June. 2) Clam farm of Kuiqi reach The water area near the south side of intended Kuiqi Bridge is the natural breed field of clams. In addition, there are 720 mu of breed aquatic area of clams of the villagers, which belong to Lianjiang Village, Shaoqi Village, Shishan Village, FulianVillage and Zhangnan Village, Chengmen Town, and Cangshan District. (3) Current situation of ecological environment of wetland. There is Puxiazhou Wetland in the northwest area of Kuiqi Bridge, where is near Xindang Overslaugh and Duimian Overslaugh with the nearest distance of 260m. 1) Flora of Wetland of Puxia Overslaugh There are mallow flora and weeping willow flora. Mallow flora belongs to herb swamp vegetation. There are a few associated plants near or around the flora, such as Ludwigia, rush, sporobolus fertile and alligator alternanthera. Weeping willow is deciduous tree, which grow on the side of rivers and belongs to woody swamp vegetation; green bamboos of weeping willow flora, which grow in clumps and compose into single dominating community, and which height of 6-8m and diameter of 9-10m, are distributed as zonal in partial regions of Puxia Overslaugh and Xindang Overslaugh. The flora covers 80%. Green bamboos, which grow flourishingly, take priority of this kind flora. There are associated plants near the flora, such as alpinia zerumbet, neyraudia reynudiana, duranta repens linn, rushes and eclipta prostrasta etc. 2) Phytoplankton and zooplankton; There are 97 species of floating algae and 79 species of zooplankton. Skeletonema costatum, coscinodiscus ehrenberg, meLosira granulata, synedra acus, navicula and chlorella of phytoplankton; halteriagrandinella muller, strombomonas ensifera, nauplius of Crustacea, sinocalanus dorrii, cyclops sp, brachionus urceus and bosminopsis deitersi etc of zooplankton take a comparative larger quantity in the water body. 3) Large-sized dermarsal invertebrate of Puxia Overslaugh and Xindang Overslaugh, where are mud beach wet land. According to sampling investigation, large-sized invertebrates include corbicula fluminea, anodonta woodiana(Heude), A.fluminea(Heude), limnophila aromatica (Lam.), cipangopaludina chinensis gray, sesarma(Parasesarma)plicata, Palaemon (Exopalamon) carincauda Holthuis, Japanese mitten-handed crab and jumping shrimp etc. 4) Plankton of wild gooses and ducks and waders provide sufficient baits for growth and propagation of aquatic organisms such as various fishes, shrimps and shells in the sea area; but fish, shrimp and shell provide material basis for habitat and feeding of various aquatic birds and migrants in wetland at the estuary of lower river, Minjiang River. There are large numbers of wild gooses and ducks and waders inhabit in Puxia Overslaugh and Xindang Overslaugh each year. But at present, only snipes and wild gooses and ducks gather and feed here. Familiar birds here include: grebe, egret, grey heron, Chinese Pond-heron, black-crowned night-Heron, spot-billed duck, common teal, common greenshank and common sandpiper. 5) There is large area of clam farms, which is provided with high density of population. In addition, there is large area of farmland, grassland and sandbank, where have abundant grains and melons and fruits, around this river section. There are various fishes, shrimps and shells as well as various insects and their grubs, which are also very important natural baits of migrants, in the water body. 14.2.2 Impact and protective measures on ecological environment(1) Impact and protective measures on land ecological environment a. Impact on agricultural production of land occupation There are 2332.43mou of land acquisition by Two Roads and One Bridge Project. Deducting woodland and space for future usage, there are 1785.36mou of agricultural land, among which are 192.38mou of vegetable land, 1188.57mou of garden plot, 59.84mou of cultivated land and 23.35mou of stew. The Phase-II Project of the Third Ring Road occupies most of farmlands and orchards. It is clear that construction of Two Roads and One Bridge Project will bring about certain impact on local agricultural economics. Yet impact on agricultural economics is not a main problem because Nantaidao Island has been planned as new downtown area and agricultural land will be changed as urban land. b. Impact on plants According to investigation of current situation, The Phase-II Project of the Third Ring Road take 105.29mou of woodlands, of which on Aoshan Mountain (Duyuan Mountain). Main species of trees are acacia, masson pines and banyan trees, as well as several diffuse camphor trees. During construction period, cinnamomum camphora shall be removed in time and not be destroyed; after road construction is finished, two sides of the road shall be greened in order reduce loss of partial plants. (2) Impact and protective measures on water ecological environment Construction of the bridge will impact on aquatic organisms in a certain period, thus the corresponding measures shall be taken: in construction period, during the process of drilling pier ground, deposition of mud fluid shall be filtered well to reduce suspended matter in the water to protect living environment of fishes; According to living habit of the freshwater eel and mitten crab, environmental pollution and ecological damage shall be reduced in the water body near the bridge, especially in the period from November to December and from May to June. Protective measures shall be enforced in case construction must be continued in the above-mentioned period. During construction period, in order to protect ecological balance and species continuance of fishes, Fuzhou Municipal Oceanic and Fishery Administration suggests to increase financial investment of propagation and openflow, organize experts to investigate and research to formulate plans of propagation and openflow of freshwater eel and mitten crab and other species of stock fish and breed on time; compensate for culturists of clam and throw in breeds of clams on time. The above-mentioned measures and means shall be adopted. In operating period, vehicle carrying dangerous articles shall be prevented from accidents to bring about obvious water pollution. Drain of the bridge surface shall not be designed and constructed to the river directly, but within the dams. Buffer tank shall set on the two ends of Kuiqi Bridge. In case pollution is released, it can be drained into the tank. All measures are in order to prevent or reduce damage on fishes and clams and reduce the impact to the lowest limit. (3) Impact and protective measures on wetland ecological environment For Puxia Overslaugh and Xindang Overslaush, where are waterlocked around all sides of perch grass-covered wetland. Except Puxia Overslaugh, there are numbers of areas of batture, grassland and sand reef of more than thousands of mu providing necessary living environment for hygrophyte; providing propagating place, feeding place and habitat for various animals, especially providing removal lines for those Asia-pacific migrants; and playing an important role in helping the living though the winter of aquatic animals and wading birds. The original design plan makes Nanjiang Binlu go though Puxiazhou Wetland. In case of constructing according to the original plan, the wetland will be destroyed seriously, therefore direction of Nanjiang Binlu shall be changed as from the starting point, to Qianheng Bridge (in planning), then to Qianheng South Road in order to avoid impact on the wetland. There are 260m from the planned Kuiqi Bridge to Wetland of Xindangzhou. The construction of the bridge will not bring about obvious impact on land ecological environment and water ecological environment; but light of construction may impact the removal of birds. According to consultation of Fujian Wild Animal Protection Managing Station, experts consider that there is a little impact.
For stone materials, there are abundant resources of granite and lave in stockyards in Mawei and Changle, and the transportation distance is 5-25km. Outsourcing is also permitted. Sand is rich in the upper section of the south port of Minjiang River and Houguan, and the transportation distance is 5-30km. In the construction of the roads, at the hilly areas near Aoshan Mountain, water loss and soil erosion is easy to occur. Therefore, measures like breast wall and sand bank etc. shall be adopted for preventing water loss and soil erosion. And after the construction it is required to take afforestation measures to avoid water loss and soil erosion. For roadbed, slopes of embankment and road-cut, it is required to take measures like plantation or engineering methods to avoid water loss and soil erosion; surface of slopes passed by the bridge and culvert are always washed by the river or channel, thus shall be taken engineering methods such as slope protection measures or revetment for; the construction access road or diverting road shall be protected mainly with plantation, supplemented by essential engineering methods.
