Abstract

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
