基于MSPA和MCR模型的株洲市生态网络构建与优化
Construction of Zhuzhou Ecological Network Based on MSPA and MCR Models
摘要
Abstract
Taking Zhuzhou City in Hunan Province as the research object,morphological spatial pattern a-nalysis 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 corri-dors 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 op-timize 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.Im-portant 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 net-work 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 theo-retical for the urban ecological network construction of ecological security pattern and also can provide sci-entific basis for the research on land space planning and ecological restoration.关键词
