流域景观格局对大型底栖动物群落结构的影响研究——以太子河山区段为例OACSTPCD
Study of the Influences of Watershed Landscape Pattems on the Community Structure of Macrozoobenthos——A Case of the Mountain Area of Taizi River
为研究太子河山区段大型底栖动物群落结构与陆地景观因子之间的相互关系,以水生态调查和遥感解译数据为基础,采用主成分分析和回归分析的方法分析了景观格局指数与大型底栖动物群落结构指数的关系,结果表明:大型底栖动物的物种数、EPT科级分类单元数(蜉蝣目、翅目、毛翅目)和ASPT指数与景现聚集度指数、最大斑块指数、连通度指数呈显著正相关,与景观香农多样性指数、分离度指数、景观形状指数呈显著负相关.研究结果反映了流域景观斑块的破碎化和人为干扰会对底栖动物群…查看全部>>
On the basis of the water ecological investigation and remote sensing data,the principal component analysis and regression analysis methods were used to analyse the relationship between landscape pattern index and macrozoobenthos community structure index,aiming at investigating the correlation between macrozoobenthos community structure and landscape factors in the mountain area of Taizi River.The results showed that the number of macrozoobenthos species an…查看全部>>
