In general, it seems that the field margin and woodland were much fitter for carabid living than cropland; and it was beneficial to protect and establish such habitat for the biodiversity in agro-ecosystem.3 Because of the long-term intensively agricultural land using and rapid urbanization, the vegetation in the Dongbeiwang village was extremely homogeneous.

不同的生境类型下步甲群落的个体数量差异很大，农田生境中步甲群落个体数量都较低，林地和农田边界地带较高；不同土地利用类型下，步甲群落的物种数量也有显著差异，农田边界处步甲群落的物种数量最多，其次为林地和与边界相邻的农田，而农田中出现的物种数量最少。

Carabid beetle was selected as bioindicators and pitfall trapping was used as sampling method for animal biodiversity evaluation; for flora evaluation, both field experiment and releve approach were used with assistance of remote sensing image; for the evaluation of soil organic carbon change, a Regional Resources and environmental information system was established; and RS, GIS and biogeochemistry model were all used to evaluate the soil organic carbon change.

生物多样性研究中，动物多样性研究部分以步甲作为指示生物展开，方法为陷阱法；植物多样性研究部分采用田间试验以及遥感影像配合下的样方记录法；对区域土壤有机碳变化的研究采用遥感、地理信息系统和生物地球化学循环模型模拟相结合的方法。
