摘要:

根据山东省地理环境和生态资源现状,收集整理相关成果数据,通过ArcGIS平台融合分析,对组成全省生态安全框架的重要生态源地、主要生态廊道和生态节点进行识别,评价生态安全格局的安全性、稳定性和连通性等。结果表明:山东省生态源占全省陆域面积的32.25%,包含生态源地图斑59块,主要集中分布在鲁中南山地、胶东半岛、南四湖和黄河三角洲区域;生态廊道总长度1.02万km,主要依托流域面积1 000km2及以上河流生态带;生态节点350个,主要分布在鲁北平原、胶东半岛东部沿海一线、鲁西南片区等区域,与生态障碍点分布高度重合。以小流域为评价单元,分析其优化提升区域布局,探讨分类分区生态保护修复对策,以期为山东省省级国土空间规划编制及开展全省生态保护与修复提供参考。

Abstract:

According to the present situation of the geographical environment and ecological resources in Shandong Province,the relevant data are collected and collated,and the important ecological sources,main ecological corridors and ecological nodes that constitute the ecological security framework of Shandong province are identified through the Arcgis platform fusion analysis,the security,stability and connectivity of ecological security pattern are evaluated. The results show that the ecological resources in Shandong province account for 32.25% of the total land area of the province,including 59 patches of the ecological source map,and are mainly distributed in the mountainous areas of south-central Shandong,Jiaodong Peninsula,Nansi Lake and the Yellow River Delta.The total length of ecological corridor is 10.2 thousand km.There are 350 ecological nodes,which are mainly distributed in the Lubei plain,the east coast of Jiaodong Peninsula and the southwest part of Shandong Province. Taking small watershed as evaluation unit,this paper analyzes its optimization and promotion of regional layout,and discusses the countermeasures of ecological protection and restoration of classified and divided areas,so as to provide reference for the compilation of provincial territorial spatial planning and the ecological protection and restoration of Shandong Province.

Key words: ecological pattern, ecological security, identification and optimization, conservation and restoration, Shandong Province
