服务高效导向下泰山区域山水林田湖草 生命共同体生态网络构建研究

泰山区域山水林田湖草生态保护修复工程作为国家第二批山水林田湖草生态保护修复工程试点,是黄河重点生态区生态保护和修复重大工程的重要组成部分。基于景观生态学"过程-格局-功能"研究框架,将生态结构系统、生态过程完整、生态功能稳定作为生态服务高效的目标导向,构建了"源地识别-廊道优化-节点选取-网络构建"山水林田湖草生命共同体生态网络构建途径。在地理信息系统和遥感技术支持下,对泰山区域生态风险进行了评价,基于形态学空间格局分析、最小累积阻力模型、重力模型等模型方法,识别与优化了泰山区域的生态源地和生态廊道,在此基础上构建了泰山区域生态网络。

Study on the Ecological Network Construction of Life Community of Mountain-Water-ForestFarmland-Lake-Grassland in Taishan Area from the Perspective of Service Efficiency

As the second batch of national pilot ecological protection and restoration projects of mountain-river-forestfarmland-lake-grassland, the Taishan area is an important part of the major ecological protection and restoration project in the key ecological zone of the Yellow River. Based on the research framework of "process-pattern-function" in landscape ecology, the ecological structure system, the integrity of ecological processes and the stability of ecological functions are considered to be the goals of ecological service efficiency, the "source identification-corridor optimization-node selection-network construction" ecological network construction pathway for the life community of mountainriver-forest-farmland-lake-grassland was constructed. With the support of GIS and remote sensing technology, the ecological risks in the Taishan area were evaluated. Based on Morphological Spatial Pattern Analysis, Minimum Cumulative Resistance model, gravity model and other modeling methods, ecological sources and ecological corridors of the life community of mountain-river-forestfarmland-lake-grassland in the Taishan area were identified and optimized. Based on the above analysis, an ecological network was constructed in the Taishan area.
