摘要:
通过对植物和蝗虫种群生物量的调查,研究了宁夏盐池县干草原沙化过程中植物和蝗虫群落结构、多样性与丰富度的变化,以及其相互关系.结果表明,植物和蝗虫群落随着草地的沙化程度表现出序列性演替过程,蝗虫群落多样性直接受植物群密结构变化的影响,但二者的变化趋势并不完全平行.草地沙化对蝗虫群落多样性和丰富度是一种灾变性影响:沙化导致植被结构与土壤硬度的变化,造成蝗虫产卵地条件的改变.
Abstract:
The biomass of plants and grasshopper population of the dry steppe at different desertification levels were investigated in Yanchi County, Ningxia, and the structure and changes in diversity and abundance of the plant and grasshopper communities in the desertification progress of the steppe, as well as their relationships were studied. The results indicated that the successions of plant and grsshopper communities occurred during the desertification progress; the changes in plant communities directly affected the diversity of grasshopper communities, but the changing trends or the two were not parallelly developing. The desertification of steppe greatly affected the diversity and abundance of the grasshopper communities, desertification led to the changes of vegetation structure and soil hardness, which changed the conditions of egg-laying habitats of grasshoppers.
