| 摘 要： | 以苏南丘陵区邓下小流域为研究区，针对目前小流域内植被物种多样性状况和水平，选择物种丰富度指数（33、Shannon—Weiner指数（SW）、Simpson指数（SP）和Pielou均匀度指数（J）作为物种多样性的测度指标，分析不同植物群落结构特征。对流域内现有主要植被类型（茶园、杉木林、马尾松林、毛竹林、水田和旱耕地共6种）以0—10cm，10—20cm，20～40cm和40～60cm分层挖土壤剖面，分析各植被类型下土壤养分效应，以期为小流域综合治理与植被恢复中植被模式选择提供理论指导。 |

| Abstract: | Taking Dengxia catchment of hilly area in southern Jiangsu province as study area,targeting at the present condition and level of plant species diversity,the indexes of species abundance(S),Shannon-Weiner(SW),Simpson(SP) and Pielou(J) were chosen to be determined as measure index of plant species diversity,and the struc-tural characteristics of different plant community were analyzed.And soil profiles of the main existing vegeta-tion types(tea plantation,Cunninghamia lanceolata,Pinus massoniana,Phyllostachys pubescens,paddy field and dry cropland) were dug into 4 layers,0~10 cm,10~20 cm,20~40 cm and 40~60 cm,effects of soil nutrient in different vegetation were analyzed,so to provide theoretical guidance to vegetation restoration and reconstruction at the catch-ment com-prehensive management. |
| Keywords: | plant diversity soil nutrients main vegetation type catchment southern Jiangsu hilly region |
