内蒙古锡林郭勒草原是我国最具代表性的典型草原，曾经是生产力较高的重要牧业区。长期以来，由于气候变化及人类的过度开发利用，草原大面积退化。本项目以锡林郭勒草原白音锡勒牧场为研究区域，对退化草原不同恢复演替阶段的昆虫群落（包括蜘蛛）进行调查，分析恢复过程中群落的组成、结构、多样性的动态变化及其与环境因子的关系，并对不同恢复措施草地中起重要生态功能的昆虫群落，包括与牧草繁衍关系密切的传粉昆虫（传粉者）和与牧草营养关系密切的土壤动物（分解者）开展调查，明确不同恢复措施对传粉者和分解者的群落组成、分布、多样性的影响，揭示不同恢复程度及不同改良措施退化草原恢复过程中昆虫群落的特征，以期为草地生态系统恢复与重建提供昆虫学依据，并为当地生态恢复效果的科学评价提供参考。

Xinlin gol steppe, the most representative one of typical steppe in China, Was once an important pasture area with higher productivity. For a long time, due to excessive exploitation and climate change, a large area of grassland has degenerated.This project choice Baiyinxile ranch in Xinlin gol typical steppe as study area, investigate insect communities (including spiders) in different restoration succession stages of degenerated steppe, analyze dynamic changes in the composition, structure, diversity of insect communities and the relationship with environmental factors in the restoration process, and research the insect communities of important ecological function in the grassland dealt with different restoration measures, including pollinating insects(pollinators) and soil animals (decomposers), make clear the effect of restoration measures on composition, distribution, diversity of pollinators and decomposers, reveal the characteristics of insect community of degenerated steppe with different degree restoration and different restoration measures. In order to provide entomological basis for the restoration and reconstruction of grassland ecosystem, and provide reference for scientific evaluation of the recovery effect of ecological restoration.
