摘    要:运用12种多样性指数综合分析了历山舜王坪草甸的物种多样性.随着放牧强度渐弱,物种多样性升高,土壤环境因子影响多样性指数,且有机质、N和K对各多样性指数的影响都较大.各群落多样性指数有大体一致的变化趋势,且其随Cu,K含量的增加而增加,说明土壤养分的增加有利于物种多样性的升高;而有机质和N增加群落多样性反而减少,这是因为人为干扰的影响超过了土壤环境因子的影响.综合以上分析得出,该研究地物种多样性指数的影响因子有放牧强度和土壤环境因子等,其中放牧的影响是最主要的.图3表3参15

关 键 词:山地草甸 物种多样性 放牧强度 土壤环境因子

Abstract:Using 12 diversity indices, the species diversity of Mountain Meadow was studied. It showed that the richness and heterogeneous indices were increased with the decrease of grazing intensity. Some results were concluded about the relationship between species diversity and soil environmental factors, such as organic matter, N and K. In the analysis of community diversity, it was obtained that Cu and K were two main influencing factors, the content of which increased with the increasing of the diversity, so the soil nutrient was helpful to increase the diversity. But the organic matter and N had negative effect on the diversity, which was different from former research. It was human disturbance that made the diversity indices decrease in spite of the high content of organic matter and N. So the human disturbance and soil factors were the factors influencing the species diversity in this research field, of which human disturbance was the main one. Fig 3, Tab 3, Ref 15
Keywords:mountain meadow  species diversity  grazing intensity  soil environmental factors
