| 摘 要： | 草地群落的退化演替以植物个体、种群与群落层次上植物的动态以及土壤理化性状的改变等现象为表征。主要从植物个体形态特征、草地退化模式、草地土壤养分变化等方面对退化的响应,探讨了草地退化演替的特征和趋势,建议今后对草地的退化演替机理、放牧生态学、恢复生态学、界面生态学及草地的价值评估等方面进行更深入的研究。

| Abstract: | The degeneration of grassland community is characterized by the trends of plant individual,the population,the community and the variations of physical and chemical features of soil.The characteristicsand trends of the degeneration grassland are discussed according to the response of the several main factorsto the grassland degeneration.The factors include the features of plant individual form,the patterns of the de-generation nd the variations of soil nutrition.It suggests that the further research must be done in some as-pects such as the mechanism of degeneration and succession of grassland,grazing ecology,restoration ecology,interface ecology,grassland value evaluation. |
