| 摘 要： | 以宁夏回族自治区盐池县柳杨堡人工封育区植被为研究对象,利用法国生态学专家Godron提出的方法测定植被稳定性.结果表明:研究区的5个样地(核心区、边缘区、外围区、新翻区和对照区)植物群落的稳定比分别为38/62、34/66、34/66、41/59和36/64,与稳定点20/80均有很大差距,表明柳杨堡封育区的植被群落不...

| Abstract: | Taking the vegetation of Yanchi County of Ningxia Hui Autonomous Region as the study object,the stability of the vegetation was determined using the method proposed by French ecologist Godron.The results indicated that the stability ratio of five sample plots(core area,edge area,outside area,new plowing area and control area)were 38/62,34/66,34/66,41/59 and 36/64 respectively.There was a big gap between the stability ratio of all the five plots and stable point 20/80,which indicated that the vegetation of L... |
