Appraisal of Land Ecological Security Based on Ecological Footprint
摘要
Abstract
Land ecological security is an important factor for the health of ecological system and sustainable development. However, it is short of systematic and effective appraisal methods. The ecological footprint method was applied to the appraisal of land ecological security based on the concept of land ecological pressure and its calculation method. The Hechuan district of Chongqing city was taken as a case study of its ecological footprint, land ecological carrying force, ecological deficit and land ecological pressure index from the year 2006 to 2010. The results showed: (1) land ecological carrying force was decreasing and land ecological pressure index was increasing with obvious deficit for the research area; (2) the land ecological security was graded as the extremely insecure within the 5 years; (3) the contradiction between land ecological need and supply was increasingly obvious. Finally, countermeasures were given for strengthening the land ecological security of the research area. The ecological footprint method is scientific and feasible in terms of land ecological security appraisal.关键词
