摘要
为探究新型城镇化背景下区域生态安全的时空演变规律及其障碍因子,以安徽省为例,构建生态安全评价指标体系,运用综合评价模型和趋势分析法测度其生态安全水平及时空演化趋势,同时引入障碍度模型对其障碍因素进行诊断分析。结果表明:新型城镇化视角下安徽省生态安全水平总体较低,呈现以合肥为核心的"核心-边缘"结构,极化现象明显。经济与城镇化发展驱动力不足和生态安全响应机制不健全是其主要障碍因素。
In order to explore the spatial-temporal evolution of regional ecological security and its obstacle factors under the background of new urbanization,taking Anhui province as an example,the index system of ecological security was constructed,and the comprehensive evaluation model and trend analysis method were used to measure the level of ecological security and spatio-temporal evolution trend.At the same time,the obstacle degree model was introduced to diagnose and analyze the obstacle factors.The results show that the overall level of ecological security in Anhui province is low from new urbanization perspective?presenting a"core-edge"structure with Hefei as the core,and the polarization phenomenon is obvious.The lack of driving force of economic and urbanization development and the imperfect response mechanism of ecological security are the main obstacles.
