摘 要：The impact of human activity on biodiversity is very complicated, making it difficult to design practical indicators for ***,state and response indicators are listed within Chapter15 of Agenda21,but no mention is made of driving force indicators and how they relate to biodiversity protection. This paper repre- sents an effort to identify and then operationalize the idea of driving force indicators at national *** human induced factors affecting biodiversity were discussed: (a) habitat loss and fragmentation; (b) overexploitation of resources;(c)species introduction;(d)pollution;and (e) climate change. From these five factors, a subsetwas selected to serve as possible driving force indicators:(1)habitat loss, (2)the ratio of exotic species to indigenous ones, and (3)the change in pollution status. Although the three indicators are relatively simple,they coverthe most important human impacts on biodiversity and offer the potential for further redefinition and ultimate use within the spirit of biodiversity protection.
