新型城镇化背景下山东省土地生态安全空间格局研究

Spatial Pattern of Land Ecological Security in Shandong Province under The Background of New Urbanization

选取了18个指标构建了土地生态安全评价指标体系,并运用熵权法来确定各个指标的权重,通过土地生态安全评价模型确定山东省各市土地生态安全综合得分。研究结果表明:济南市、青岛市、烟台市、威海市为理想安全型;淄博市、泰安市为较安全型;枣庄市、潍坊市、日照市、聊城市的土地生态安全属于临界安全型;东营、德州和莱芜属于较不安全型;而菏泽、济宁、临沂、滨州则属于极不安全型。

This article constructed the index system of land ecological security evaluation from 18 indices.Using entropy weight method to determine the weight of each index,through the land ecological security evaluation model to determine the comprehensive scores of land ecological security.The result shows that,Jinan,Qingdao,Yantai,Weihai belong to safe ideal safe type.Zibo,Tai'an belong to safe type.Zaozhu-ang,Weifang,Rizhao,Liaocheng belong to critical safety type,Dongying,Dezhou and Laiwu belong to less safe type,and Heze,Jining,Linyi,Binzhou belong to extremely unsafe type.
