Abstract: Increasing species loss due to human-induced habitat destruction is a formidable task in conserving global biodiversity. In order to reverse the negative situation in which traditional theories and practices can hardly stop the trend of species extinction, a holistic strategy for biodiversity conservation at landscape and regional levels is raised and underpinned by GAP analysis approach. GAP analysis is to integrate land cover, species distribution and land stewardship in a GIS context to identify the "gaps" that need special attentions in the future planning of regional biodiversity conservation and land use. This paper reviewed the GAP Analysis Program in US focusing on its basic technical processes, related theories and practical progress made recently as well as the key constraints in application. Also, necessity in theory and application to conduct similar research and applications in China is discussed based on the key issues existing in the biodiversity conservation in China.
