4.6 Impact on ecologic environment and preventive measures4.6.1 Impact land ecologic environment and protective measuresa. Impact on agricultural production resulted from land tenure 2332.43mu land was requisitioned for the construction of two roads and one bridge, if forest land and unutilized land are deducted, farmland totals 1785.36, out of which vegetable plot is 192.38m; orchard is 1188.57mu, cultivated land is 59.84mu, and fish pond is 23.35mu. The Phase-II Project of the Third Ring Road occupies the most of the farmland and orchard. Refer to Table 4.6-1 for details. So we can come to know that construction of the two roads and one bridge will have a certain impact on farm economy along the line. But the whole Nantaidao Island is planned to become a new urban area, farmland will be transferred into urban land tenure, so the impact on farm economy is not the main issue. Table 4.6-1 Farmland used for the two roads and one bridge
b. Impact on plant According to site survey, the Phase-II Project of the Third Ring Road occupies forest of 105.29mu mainly at Aoshan (also called Duyuanshan). Main species are rich acacia, masson pines, banyan trees and a dozen of scattered camphor trees. During project construction, if there are camphor trees, they should be transplanted timely, it is forbidden to destroy them. After completion of project construction, both sides along the project shall be planted with trees so as to reduce part of plant losses. 4.6.2 Impact on water ecologic environment and protective measuresDuring bridge construction, it would cause certain impact on water living things as mentioned above. So we mush take the following corresponding measures to avoid or reduce adverse impact: during project construction, when constructing the pier foundation, mud shall be settled and filtered so as to reduce floating articles in the water and protect fishes’ living environment; in accordance with the living habits of fresh water eel and Chinese mitten-handed crab, reduce environmental pollution and ecologic damage in the water area near the bridge, especial during the periods of November～December and May～June every year. If the construction shall be performed during the above periods, protection measures should be taken. Fuzhou Marine and Fishery Bureau points out that, during bridge construction, in order to protect fish’s ecologic balance and species continuance, it is suggested that funds should be increased for breeding release; it shall organize specialists to survey and work out a plan to release breeding parent fishes and fry of the freshwater eel and Chinese mitten-handed crab regularly; give Corbicula leana raisers proper compensation and periodically release Corbicula leana fry. All those methods and measures should be adopted. During operation, in order to avoid possible significant water pollution resulted from an accident of the vehicle transporting dangerous products, surface water flow on the bridge shall be designed and constructed not directly to flow to the river beneath the bridge, it shall drain to the dyke where buffer tanks are built, i.e. buffer tanks should be built on both ends of Kuiqi Bridge, so when there is a pollutant leakage, the leaked pollutant could be led to the tanks. All those are measures to prevent or reduce any impact that may danger the living conditions of the fishes and Corbicula leana, and minimize the impact. 4.6.3 Impact on wetland ecologic environment and protective measuresPuxiazhou and Xindangzhou are high grass wetlands surrounded by water. Besides Puxiazhou, there are several flood land, grassland, sandbank with areas ranging from sever thousands to ten thousands mu at the Minjiang river mouth area. They provide the hygrophyte with a necessary growing environment; provide various animals with breeding grounds, feeding grounds and fine habitats. And especially, as an important habitat of the migratory birds in Asia and Pacific regions, it serves as an irreplaceable place for various aquatic birds and wading birds to live through the winter. The former design of Nanjiang Binlu was through the Puxiazhou wetland. If that plan were implemented, this piece of wetland would be seriously destroyed. Therefore, the location of Nanjiang Binlu should be changed, which shall not pass through the wetland. When Nanjiang Binlu starts from the starting point and gets Qianhuang Bridge (a proposed bridge), it turns to Qianheng Nanlu so as to avoid impact on the wetland. The proposed Kuiqi Bridge is 260m away from the Xindangzhou wetland. Construction of the bridge will not produce significant impact on wetland’s land and water ecologic environment. But during project construction, light may have impact on migration of the migratory birds, after we consulted to the specialists of the Fujian Wild Animal Protection Management Institute; the specialists told us that the impact would be relatively small. 4.6.4 Construction impact on ecologic landscape and preventive measures4.6.4.1 Impact on ecologic landscapeDuring project construction, the impacts on ecologic landscape are as follows:
4.6.4.2 Protection measures for ecologic landscape during construction periodDuring construction, the existing ecologic landscape environment may change at once; construction shall be performed section-by-section or piece-by-piece. Ecologic landscape environment along the line should be properly protected. Attentions that should be paid to are as follows:
4.6.5 Measures to protect ecology and prevent water and soil lossNanjiang Binlu and the Phase-II Project of the Third Ring Road are mainly built on the plain, but Kuiqi Bridge is bridging, so generally speaking, water and soil loss is not serious. Only when the Phase-II Project of the Third Ring Road passes Aoshan (also called Duyuanshan), earth is needed for filling. But the earth engineering is balanced, it is unnecessary to set up a borrow ground or a refilling ground. Stone material can be taken from Mawei and Changle where there are rich granite and lava reserves. The transport distance is 5 to 25km. Sand can be taken from Nangang or Houguan upstream. The transport distance is 5 to 30km. Water and soil loss may happen at Aoshan hilly zone during the construction of the road. In order to prevent water and soil loss, retaining wall and grit chamber shall be built for road construction. After completion of the construction, forestation shall be made to prevent water and soil loss. Roadbed is divided into embankment and cut slope. Planting or engineering measures shall be taken to prevent water and soil loss from those positions. Bare slope surfaces where bridge and culvert pass are always scoured by water, so they shall be protected with embankments and dykes. Temporary path for construction or new path shall be treated mainly with planting measures and necessary engineering measures.
