- 摘要:
- 为了探究承接产业转移示范区的土地生态安全状况，在阐述土地生态安全概念的基础上，基于“驱动力—压力—状态—影响—响应”模型构建土地生态安全评价指标体系，商权法与层次分析法相结合测算各指标权重，运用物元分析法构建土地生态安全评价的综合评判模型，并以合肥市为例进行了实证研究。结果表明：2005—2009年、2011年合肥市土地生态安全级别为“不安全”，2010年为“较不安全”，2012年合肥市土地生态安全级别为“临界安全”；总体来看，2005—2012年合肥市土地生态安全呈现从“不安全”到“临界安全”跃升的趋势。该结论可为承接产业转移的合肥市社会经济健康、持续发展提供理论依据。
- Abstract:
- In order to explore the land ecological security situation of industrial transfer demonstration region, on the basis of the concept of land security and driving-pressure-state-impact-response model, the land ecological security evaluation indicator system was established. Analytic hierarchy process(AHP)and quotient method were applied to determine the weight of indicators. Matter-element analysis method was used to build the comprehensive evaluation model of land ecological security evaluation, and Hefei City was taken as an example for the case study. Through analysis, we draw the following conclusions. The land ecological security level of Hefei from 2005 to 2009 and 2011 was insecurity, it was less security in 2010, and was critical security in 2012. Overall, the trend of land ecological security in Hefei city zoomed from insecurity to critical security. The conclusion could be used to provide theoretical basis for the social and economic sustainable development under the situation of industrial transformation in Hefei city.
