中文摘要	维护生态安全格局对于生态环境的维护和改善、支撑经济社会可持续发展具有重要作用。生态保护红线是识别区域生态安全格局的基础框架和关键组分,划定生态保护红线有助于保障生态安全。为研究山西省生态安全格局空间识别,结合山西省生态环境现状,应用水源涵养、水土流失、维护生物多样性、防风固沙生态系统服务功能与水土流失、土地沙化生态敏感性评价划定生态保护红线的方法,利用最小累积阻力算法的思想,通过确定生态保护红线为生态源地、进而得出缓冲区、生态廊道、辐射通道和战略节点识别生态安全格局。结果表明:研究区生态安全格局分为三级,依次分为高安全水平格局、中等安全水平格局和最低标准安全水平格局,各分区面积比例分别为24.45%,25.66%和30.24%,有效突出了山西省生态安全格局分布,为保障我省生态系统的完整性、生态系统服务功能的重要性具有重要的意义。
英文摘要	Maintenance of ecological security pattern is important for the maintenance and improvement of the ecological environment,and has an important role to support sustainable economic and social development. Ecological protection red line is the basic framework and the key component of ecological security pattern,the delineation of the red line has contributed to protect the ecological security.In order to study the spatial pattern of ecological security pattern in Shanxi Province,combining with the current situation of ecological environment in Shanxi province,we used the evaluation ecosystem service function of water conservation,soil erosion,biodiversity maintenance,windbreak and sand fixation,and the ecological sensitivity of soil and water loss,land desertification to delineate ecological protection red line,used the minimum cumulative resistance algorithm to determine the source-ecological protection red line and buffer zone,ecological corridor,radiation channel and strategic nodes to identify ecological security pattern.Above all,classification of ecological security in the study area,the ecological security will be divided into the pattern of high level security,low level security and the lowest standard level security,the proportions of the areas were 24.45%,25.66%and 30.24%,respectively.It is important to highlight the distribution of ecological security pattern in Shanxi Province,which is of great significance to ensure the integrity of the ecosystem and the importance of ecosystem services.
