人为干扰对北京野鸭湖市级自然保护区植物多样性的影响
Effects of anthropogenic disturbance on plant diversity in Yeyahu Municipal Natuer Reserve of Beijing
摘要
Abstract
Species richness ( S) , Shannon-Wiener index ( H) , Simpson index ( D) and Pielou evenness index( E) , Jaccard index ( Cj ) and Sörenson index ( Cs ) were used to study species diversity under 3 different disturbance of Yeyahu Municipal Nature Reserve in Beijing.The 3 different disturbance intensities were low interference, interference and strong interference.Among them, species richness were 83, 93 and 30.It showed that the species richness in interference region was the largest, it accorded to the Intermediate Disturbance Hypothesis.The trends of diversity(H), dominance(D) and evenness(E) were substantially the same , but they had no simple relationship with species richness . Meanwhile the similarity of plant communities was basically in proportional to the total number of species.In conclusion, by comparing the species diversity of plant communities before and after the wetland restoration, it was proved that short-erm recovery of the species was not obvious .The wetland protection and restoration projects had a long way to go.关键词
