摘要: 在快速城市化的背景下,构建城乡生态安全格局是中国缩小城乡生态安全水平差距,促进城乡生态融合发展的重要途径。城乡生态差异性导致城乡生态融合发展进程缓慢。以城乡生态融合为导向,以武汉市为例,分析当前城乡生态融合水平及其影响因素,并基于此测算生态融合综合影响度构建综合生态阻力面,识别中观尺度下的生态源地,基于最小累积阻力和重力模型识别重要生态廊道,利用水文分析模型优化廊道,从中观尺度构建了武汉市城乡整体生态安全格局。研究表明:(1)武汉市城乡生态融合水平存在明显的空间分异,城乡生态处于不平衡的发展状态;(2)城乡生态融合发展的主要驱动力为生态环境和人为活动因素,社会经济影响较小;(3)构建了包括51个城乡生态源地,115条重要生态廊道,220条辐射廊道,129个生态节点的“三横两纵”网状生态安全格局;(4)城乡生态融合影响度指数修正的生态阻力面更符合城乡实际,由此构建的生态安全格局具有促进城乡生态融合发展的作用。构建武汉市城乡生态安全格局,以期为城、乡的生态空间优化提供更微观的理论参考,为促进城乡生态融合、保障城乡生态安全及促进区域可持续发展提供科学参考。

Abstract: In the context of rapid urbanisation, building an urban-rural ecological security pattern is an important way for China to narrow the gap between urban and rural ecological security levels and to promote integrated urban-rural ecological development.The urban-rural ecological differences lead to the slow process of urban-rural ecological integration development.Taking Wuhan city as an example and urban-rural ecological integration as an orientation, this paper analyzed the current level of urban-rural ecological integration and its influencing factors.A comprehensive ecological resistance surface based on the measurement of the comprehensive impact degree of ecological integration was constructed.The ecological sources at meso-scale and theimportant ecological corridors based on the least cumulative resistance and gravity model were identified.The corridors were optimized by using a hydrological analysis model, and an overall urban-rural ecological safety pattern in Wuhan was constructed.This study showed that: (1) There was obvious spatial differentiation in the level of urban-rural ecological integration in Wuhan, and urban-rural ecology was in an unbalanced state of development; (2) The main driving force for the development of urban-rural ecological integration was the ecological environment and anthropogenic activity factors, with less socio-economic impacts; (3) A ‘three horizontal and two vertical’ network of ecological security patterns were constructed, which included 51 urban and rural ecological sources, 115 important ecological corridors, 220 radial corridors and 129 ecological nodes; (4) The ecological resistance surface corrected by the urban-rural ecological integration influence index was more in line with the urban-rural reality, and the ecological security pattern demonstrated the effect of promoting the development of urban-rural ecological integration.The ecological security pattern of urban and rural areas in Wuhan was constructed to provide a more microscopic theoretical reference for the optimization of ecological space in urban and rural areas, as well as to provide a scientific reference for the promotion of ecological integration between urban and rural areas, for the safeguarding of ecological security in urban and rural areas, and for the promotion of sustainable development in the region.
