摘要:Yangtze River Economic Zone is a large scale with a wide span and significant ecological differences. In this article, based on 1088 natural reserves in Yangtze River Economic Zone, 10 different types of ecological zones are divided by patch density, patch direction and patch connectivity, combined with their respective topography, weather and climate conditions. Connecting the 10 ecological belts, Yangtze River Economic Belt can be formed into an ecological net-work with one horizontal axis and four vertical axes. According to the patch density and connectivity of the natural re-serve, the ecological network can be divided into maintenance area, steady construction area and accelerating construction area. In the maintenance area, due to the significant differences in patch patterns, the west belt should maintain the func-tion as natural reserves, while the middle belt and east belt should serve as the channel between patches. In the steady construction area, the ecological land should be connected by ecological land with certain economic functions. The steady construction area lies in the developed areas, so the urban ecological corridors and landscape parks should expand the green areas and improve the ecological network.%长江经济带面积大,跨度广,生态水平差异大.以长江经济带1088个自然保护区为基础,根据斑块密度、斑块走向、斑块联通度等,结合地形地貌、气象气候等条件,在长江经济带划出10条不同类型生态带.将这10条生态带连接后,可以在长江经济带协调性均衡构建"一横四纵"的生态网络.在这一网络中,根据自然保护区斑块密度和联通度,划分成保持维护区、稳步建设区和加速建设区.在保持维护区,西部和中东部在斑块格局特征上差异显著,对于西部主要是保持自然保护区面积,而对于中东部则要将保持保护区面积和维护斑块间通道相结合;稳步建设区应结合具有一定经济作用的生态用地,加强斑块联通;加强建设区位于经济较发达地区,应结合城市生态廊道,景观公园等扩大绿地面积,完善生态网络.
