摘要: 山西万家寨引黄工程从万家寨水利枢纽至太原市呼延水厂, 全长285.03 km 。引黄工程沿线有种子植物1 040 种, 隶属于422 属100 科, 其中裸子植物3 科5 属9 种;被子植物97 科417属1 031 种(双子叶植物79 科321 属793 种, 单子叶植物18 科96 属238 种)。引黄工程沿线种子植物属的区系成分类型多样, 具有明显的温带色彩。突出特征是温带成分占优势, 达246 属, 占总属数的58.29%(其中北温带成分155 属, 占总属数的36.73%), 在植物区系的组成中具有重要作用。在引黄工程沿线种子植物种的区系成分中, 中国特有种占绝对优势, 达311 种, 占总种数的29.90%, 它们是构成引黄工程沿线优势植被类型的建群种和优势种的主要成分, 如青、华北落叶松、油松、小叶杨、青杨、垂柳、旱榆和黄刺玫等。

Abstract: ShanxiWanjiazhai Yellow River Diversion Project (YRDP)is a large diversion project from Wanjiazhai, Pianguan to Huyan, Taiyuan, and its length is about 285.03 km totally.It plays an important role in solving the problem of the absence of water resource in Taiyuan and Datong.There are 1 040 species of seed plants alongside YRDP that is a transect 285.03& #215;1 km2, belonging to 422 genera and 100 families, among which gymnosperms have 3 families, 5 genera and 9 species, and angiosperms have 97 families, 417 genera and 1 031 species.The angiosperms are composed of dicotyledon and monocotyledon, having 79 families, 321 genera and 793 species, and 18 families, 96 genera and 238 species, respectively.The flora of genera has some typical characteristics of warm-temperate flora.Among them, temperate distribution elements, having 246 genera and accounting for 58.29% in total genera, hold a significant dominant position.Moreover, among the floristic elements of species, endemic to China has 311 species, accounting for 29.90% in the total, and makes evidently dominant, and they are the major elements of the edificatos and dominant species of dominant vegetation types, such as Picea vilsonii, Larix principis-rupprechtii, Pinus tabulaeformis, Populus simonii, Populus cathayana, Salix babylonica and Ulmus glaucesens.
