摘要

Based on clarifying of related conceptions of land ecological security, this paper discusses the evaluation methods on regional land ecological security. Taking Hangzhou City in Zhejiang Province as study region, from the aspects of nature, economy, society, and according to PSR model, 18 indexes, which have significant impact on the ecological security in the region, are selected to construct the land ecological security evaluation index system. Moreover, the Analytic Hierarchy Process model is introduced to ascertain the weight of each index, and then each index's safety indicator. The land ecological security values are calculated from 2000 to 2006, and the result shows that during this period, although there is some improvement in Hangzhou City, the land ecological security is still in the grade of “Common”.
