摘要:
 为解决快速城镇化导致的生态空间布局破碎等问题，构建起湖南省东部重要生态屏障，以湖南省株洲市为对象，通过形态学空间格局分析和景观连接度水平评价，筛选出景观连通性较高的生态源地斑块，基于最小累积阻力模型和重力模型，提取生态廊道并对生态廊道重要性进行评价构建株洲市生态网络，根据株洲市历史文化景观资源对生态网络进行优化。结果表明，1）初步构建的生态网络包括25个生态源地和300条生态廊道，共判别97个生态节点和92个生态障碍点，其中，市辖区及醴陵市西部、攸县北部的生态源地破碎化程度较高，生态廊道在东北部市辖区、西北部和攸县东部分布较少，重要生态节点主要分布在株洲北部，生态障碍点总体上呈现北多南少。2）增加了12个踏脚石斑块，其中4个作为补充生态源地，同时也新增106条生态廊道，以实现生态网络的优化。3）优化后的生态网络连通性增强，网络闭合指数、网络连接度指数和网络连通率指数分别增加了0.96、2、0.66。研究结果可为市域生态网络体系构建和国土空间规划与生态修复等研究提供参考和理论依据。
Abstract:
 Taking Zhuzhou City in Hunan Province as the research object,morphological spatial pattern analysis and landscape connectivity index were used to extract ecological source patches with high landscape connectivity.Based on minimum cumulative resistance model and the gravity model,the ecological corridors were extracted and the importance of the ecological corridors was evaluated to construct the ecological network of Zhuzhou City.The historical and cultural landscape resources of Zhuzhou City were used to optimize the ecological network.The research results showed that 1) the preliminarily constructed ecological network included 25 ecological sources and 300 ecological corridors,and a total of 97 ecological nodes and 92 ecological obstacle points were identified.The degree of fragmentation was relatively high.Ecological corridors were less distributed in the northeastern municipal area,northwest and eastern You District.Important ecological nodes were mainly distributed in the northern part of Zhuzhou.Ecological obstacle points were generally more in the north than in the south.2) Therefore,12 stepping stone patches were added,4 of which were used as supplementary ecological sources,and 106 new ecological corridors were also added to optimize the ecological network.3) After optimization,the connectivity of the optimized ecological network was enhanced,and the network closure index,network connectivity index and network connectivity rate index increased by 0.96,2 and 0.66,respectively.The research results can provide reference and theoretical for the urban ecological network construction of ecological security pattern and also can provide scientific basis for the research on land space planning and ecological restoration.
