4 Assessment of Ecological Environment and Protective Measures4.1 Terrestrial Ecological Environment4.1.1 Current situation of plants along the ling areaOwing to the influence of human activities, the original vegetation in the area has disappeared long ago, being replaced by successive vegetation and artificial vegetation, the structure of which is rather monotonous with few species and low quality forests. The major tree species are the Chinese Red Pine (Pinus massoniana), Taiwan Acacia subtropics (Acacia confusa), Japanese Black Pine (Pinus thunbergii), Tea-oil Plant(Camellia oleifera), Slash Pine (Pinus elliottii), Black Wattle (Acacia mearnsii), Phyllostachy makinoi, and Moso bamboo (Phyllostachys pubescens); the major fruit trees are tropical, subtropical and temperate zone fruits such as Loquat (Eriobotrya japonica), Citruses (Citrus spp.), and Longan (Dimocarpus longan); the major shrubs are Box-leaved Syzygium (Syzygium buxifolium), Downy Rose Myrtle (Rhodomyrtus tomentosa), Sea Bilberry (Vaccinium bracteatum), Indian Azalea (Rhododendron simsii), Gardenia (Gardenia jasminoides), Chinese photinia (Photinia serrulata), Chinese Eurya (Eurya chinensis), Sapphireberry Sweetleaf (Symplocos paniculata), Black Cutch (Acacia catechu) and Manyflower Glorybower (Clerodendron cyrtophyllum); the dominant herbaceous species is the False Staghorn Fern (Dicranopteris linearis) with others like the Giant Chinese Silvergrass (Miscanthus floridulus), Elecampane (Inula cappa), Hirsute Arundinella (Arundinella hirta) and Common Lophantherum (Lophantherum gracile); of the creepers there are the Evergreen Wisteria (Millettia reticulata), Cherokee Rose (Rosa laevigata), Shiny-leaved Prickly Ash (Zanthoxylum nitidun), Japanese Hawthorn (Crataegus cuneata) and Common Indian Mulberry (Miranda umbellata); in addition can be found tree saplings of the Chinese Gugertree (Schima superba) and Sweetgum (Liquidambar formosana). The forest coverage attained 19% for Nantaidao Island as of August 1999, being mostly concentrated in rolling and hilly areas. Landscaping construction in urban areas during the 9th Five-year Plan accomplished an increase of 418.65 hectares in greenery, planting 1 million shrub plants and turfing 516 thousand square meters. Utilized were 215.5 thousand bags of turfing material and 26 thousand pots of flowers in bloom. In all, 667.23 hectares of verdure were built, making the greenery rate 30.24%, with a 7.29-square meter per capita share of public green space. 4.1.2 Current situation of forest resourcesHilly land comprises about 65% of Nantaidao Island, resulting in a relative abundance of forest resources. Reforestation efforts revolving around the target of establishing an ecological and commercial forest system during the 9th Five-year Plan,, realized a 3-year "Fuzhou Green Barrier Restoration" project by forestation of 358.7 hectares; over the entire area 466.7 hectares were planted to forest, 278.7 hectares to fruit trees and 13 ecological forest and commercial forest areas were set up. The total forest area for the whole region as of August 1999 was 4259.3 hectares, representing a 19% forest coverage. The forest in the region can be classified as suburban type, mainly comprising shelter forest, commercial forest, and forest for special use. Forest species mainly consist of Chinese Red Pine and Taiwan Acacia, whereas commercial forests chiefly include Longan, Litchi, Chinese White Olive (Canarium album), Wampi (Clausena lansium), bamboo shoots and flowers, with ornamental plantation, White Jade Orchid Tree (Michelia alba) and Buddhist Bauhinia (Bauhinia variegata) to match. During the 10th Five-year Plan period, the forestry program of the Cangshan District for 2001 through 2005 is to allocate more than 4000 hectares for forestry usage, occupying 27% of the land acreage, of which 2933 hectares would be under forest. Arrangement will be made to subject 666.7 hectares of sparsely wooded and treeless land forming existing wasteland and sandbanks to forestation during this five-year period at a rate of 133.3 hectares per year, completing the whole 666.7 hectares at the end of five years. Commercial forest will be increased by 66.67 hectares annually to attain an aggregate of 333.3 hectares after five years and accounting for over 50% proportionally. While keeping in mind the target of constructing ecological forests, the forestry agency of Canshan District will, after setting up ecological and commercial forests, proceed further with improving the management in the following three areas: augmenting forestry resources, intensifying forest fire-prevention and upgrading pest control. The program requires that after subtracting 60 hectares of forestland diverted to other uses and consumed in timber production, the annual net increase in forest area should be 73.33 hectares, representing net increase in forest coverage of 3%, which should by 2005 attain 21%. A yearly quota limit of 600 cubic meters for timber production, a 3.6-hectare forest fire damage allowable acreage, and a minimum 80% forest pest control target will be instituted. 4.1.3 Current situation in greenery constructionThe total green surface built in the Nantaidao Island district is 695.77 hectares at present, of which public green space covers 153.09 hectares, exclusive green space (including green spaces in residential areas and those attached to units) 109.87 hectares, greenery devoted to production 29.1 hectares, green surface in scenic spots and famous sites 389.47 hectares, and roadside green space 14.24 hectares. The per capita share of public green space is 7.29 square meters, the green coverage ratio 34.65％，and the green surface rate 30.24％. 4.1.4 Survey and assessment of ecological status along the road will be builtGreen space along the Nanjiang Binlu has been completed, the landscaping of Cangqian Road being very good, where are planted chiefly Smallfruit Fig (Ficus microcarpa) with some Mango (Mangifera indica) and Buddhist Bauhinia; the remaining space consists mostly of demolished buildings with sparse sprinkling of trees. Field inspection of the terrain and land contour, land utilization, fauna and flora along the Phase-II Project of the Third Ring Road has provided relevant information, the survey of the existing ecological status revealing that along the line are mainly Mandarine (Citrus reticulata) orchards with a small amount of agricultural fields and vegetable plots, the fields interspersed with some Banana (Musa acuminata), Longan and Pomegranate (Punica granatum) plantations. There is a man-made forest at Aoshan (also called Duyuanshan) with luxuriant tree growth, the major species being Taiwan Acacia, Chinese Red Pine and Smallfruit Fig (Ficus microcarpa). For the investigation and survey findings, see table 4.1-1. On both sides of the viaduct at the southern end of the Kuiqi Bridge are cultivated fields, whereas at the northern end there are mostly demolished buildings with few trees.
