基于生态足迹的潞安矿区土地利用可持续评价研究

Study on Sustainable Appraisal for Land-Use in Luan Mining Area Based on the Method of Ecological Footprint

采用生态足迹分析法和可持续发展模型法,对潞安矿区2005年土地利用实施可持续评价研究。研究结果表明:①潞安矿区2005年的人均生态足迹为2.3533hm2/人,而人均承载力为0.5978hm2/人;②生态赤字为1.7553hm2/人;③生态压力指数等级为3级;生态占用指数等级为3级;生态经济协调指数等级为1级;可持续发展指数等级为2级。表明潞安矿区是在生态赤字的前提下发展的,是一种弱可持续发展模式;提出了相应的发展建议。

The sustainable appraisal for land-use in Luan mining area in 2005 was studied based on the method of ecological footprint and sustainable development model. The results showed that per-capita ecological footprint was 2.353 hm^2, and per-capita ecological capacity was 0.597 8 hm^2 in Luan mining in 2005; per-capita ecological deficit was 1.755 3 hm^2; the grade of ecological tension index, ecological occupation index, eco-economy coordinate index and sustainable development index were Ⅲ, Ⅲ, Ⅰ, Ⅱ resp. These results indicated that the development of Luan mining area was on the premise of ecological deficit, and it was a weak sustainable development mode and the corresponding development suggestions were put forward.
