人为干扰对黄河湿地植物群落的影响及其机制
Effects of Human Disturbances on Plant Community of the Yellow River Wetland and its Mechanisms
摘要
Abstract
In order to analyze the different types of influence of human disturbance on plant communities in the Yellow River wetland and the relevant mechanisms,three wetlands in Zhengzhou section which were respectively af-fected by agricultural planting,reservoir construction and building construction,were selected after conducting a large number of field investigations.After measuring the plant communities and related environmental factors,re-dundancy analysis was carried out based on human pressure index evaluation system.The results showed that the whole wetland plant community showed an obvious degradation trend,and the function of productivity maintenance decreased.For the sample land with different types of human disturbance,the severity of human disturbance varied from the disturbance caused by reservoir construction to agricultural planting,and building construction.With in-tensification of the severity of human disturbance,the similarity coefficients of plant communities in different wet-lands declined successively,and the species richness index of wetland in Bird Nature Reserve and Taipingzhuang North wetland decreased by 15.98%and 37.05%,respectively,compared with the Taohuayu wetland,indicating that the overall construction of wetland plant communities gradually became simpler.Among the many factors cau-sing wetland degradation,the change of ammonium nitrogen content in soil had a significant negative correlation with species diversity index and species evenness index,and was one of the main reasons for wetland plant degrada-tion.关键词
