摘要
进行了镜湖湿地植物群落的调查研究,研究了不同干扰条件下(林地区、草地区、水库区与建设用地区)镜湖湿地植物多样性概况。研究结果表明:镜湖湿地4个区域中共有植物物种150种,分属75科90属,主要以被子植物为主(140种)。①林地区域上共有植物103种,优势物种合欢(Albizia julibrissin Durazz.)的株高,样方所有植物盖度及生物量分别为75.6 cm,85.6%,1608.1 g/m^2,该区的Shannon-Winner指数,Pielou均匀度指数和Simpson植物优势度指数分别为2.1,0.9与0.64;②草地区域共有植物95种,优势物种早熟禾(Poaannua L.)的株高,样方所有植物盖度及生物量分别为20.1 cm,79.4%,387.9 g/m^2,Shannon-Winner指数,Pielou均匀度指数和Simpson植物优势度指数分别为1.8,0.7与0.65;③水库区域上共有植物69种,优势种喜旱莲子草(Alternanthera philoxeroides(Mart.)Griseb)的株高,样方所有植物盖度及生物量分别为6.3 cm,59.3%,227.8 g/m^2,Shannon-Winner指数,Pielou均匀度指数和Simpson植物优势度指数分别为1.1,0.4与0.8;④建设用地区域上共有植物73种,优势种诸葛菜的株高,样方所有植物盖度及生物量分别为18.9 cm,55.8%,355.4 g/m^2,Shannon-Winner指数,Pielou均匀度指数和Simpson植物优势度指数分别为1.2,0.5与0.7。从整体上看,绍兴镜湖湿地植物资源较丰富,物种多样性较高,但不同干扰条件,会影响不同区域的物种多样性及物种组成。
Based on the investigation of plant communities in JingHu wetland,the species diversity under different disturbance conditions(forest area,grass area,water storage area and construction area)was studied.The result showed that there was a total of 150 plant species,belonging to 75 families and 90 genera,in the four areas of JingHu wetland,which was mainly angiosperms(140 species).①There were 103 species in the woodland area.The height of dominant specie(AlbiziajulibrissinDurazz.)was 75.6 cm.The plant cover and biomass of each plot was 85.6%,1608.1 g/m^2,respectively.The Shannon-Winner diversity index,Pielou evenness index and Simpson index was 2.1,0.9 and 0.64,respectively.②There were 95 species of plants in the grassland area.The height of dominant specie(Poaannua L.)was 20.1cm.The plant cover and biomass of each plot was 79.4%,387.9 g/m^2,respectively.The Shannon-Winner diversity index,Pielou evenness index and Simpson index was 1.8,0.7 and 0.65,respectively.③There were 69 species of plants in the reservoir area.The height of dominant specie(Alternanthera philoxeroides(Mart.))was 6.3 cm.The plant cover and biomass of each plot was 59.3%,227.8 g/m^2,respectively.The Shannon-Winner diversity index,Pielou evenness index and Simpson index was 1.1,0.4 and 0.8,respectively.④There were 73 species of plants in the construction land area.The height of dominant specie(Orychophragmus violaceus)was 18.9cm.The plant cover and biomass of each plot was 55.8%,355.4 g/m^2,respectively.The Shannon-Winner diversity index,Pielou evenness index and Simpson index was 1.2,0.5 and 0.7,respectively.In short,JingHu wetland was rich in both plant resources and species diversity,but different disturbance conditions affected species diversity and species composition.
