摘要: 为了促进武汉城市圈整体的土地可持续利用,均衡系统内部各市域土地生态安全水平,探究城市个体与城市圈整体的状态和差异。以各市域和整体区域为研究对象,以改进的文献参考法为基础,结合DPSIR模型构建武汉城市圈土地生态安全评价指标体系,使用主成分分析法计算2015年各城市土地生态安全水平综合值,并比较了整体与各市域水平间的差异。结果表明,武汉城市圈整体土地生态安全水平良好,但城市圈内部各市域发展较不均衡;总体表现为南北纵向水平差异优于东西横向差异,并呈现出从中心至外环逐渐恶化的趋势;城市规模、城市化水平与土地生态安全水平没有直接的线性关系;根据地生态安全值,将组成城市圈的9个独立市域划分为4个阶梯并给出相应的措施进行改善。

Abstract: In order to promote the sustainable use of the land in Wuhan Metropolitan Area,to balance the level of land ecological security in all municipalities within the system,explore the status and differences of urban individual and the whole area. Therefore,based on the improved literature reference method and the DPSIR model,the evaluation index system of land ecological security of Wuhan Metropolitan Area was constructed,using principal component analysis to calculate the comprehensive value of urban land ecological security in 2015,then,compared the difference between the whole and the city level. The results show that:the overall ecological security level of Wuhan Metropolitan Area is good,but the development of cities within the group is relatively uneven. There is no direct linear relationship between urban scale,urbanization level and land ecological security level. According to the ecological security value, the nine independent cities that make up the Wuhan Metropolitan Area are divided into four ranks and the corresponding measures are given.

Key words: ecological security, Wuhan Metropolitan area, evaluation, principal component analysis
