重庆市两江新区生态空间识别方法

Method of Delimiting Ecological Space in Liangjiang New Area of Chongqing based on Multi-source Data

生态空间是国土空间的重要组成部分,合理识别生态空间有利于维持经济发展和生态保护动态平衡。两江新区为内陆首个国家级开放新区,科学识别两江新区生态空间极为重要。该文基于多源遥感数据构建生态敏感性和生态系统服务功能重要性评价体系,再结合生态用地类型,识别两江新区生态空间范围。主要结论如下:(1)研究区生态敏感性以敏感为主,高度敏感以上区域为418.55 km^(2),面积占比为36.03%。(2)研究区生态系统重要性类型相对较为平均,中等重要以上区域为706.67 km^(2),面积占比为60.85%。(3)该文识别出来的两江新区生态空间面积为336.78 km^(2),约占研究区29%,生态用地类型以林地为主。

Ecological space is an important component of national land space,and reasonable identification of ecological space is conducive to maintaining dynamic balance between economic development and ecological protection.Liangjiang New Area is the first national level open new area in inland China,and it is extremely important to scientifically identify the ecological space of Liangjiang New Area.This article constructs an ecological sensitivity and importance evaluation system for ecosystem service functions based on multi-source remote sensing data,and identifies the ecological spatial range of Liangjiang New Area by combining it with ecological land types.The main conclusions are as follows:(1)The ecological sensitivity of the study area is mainly sensitive,with a highly sensitive area of 418.55 km^(2),accounting for 36.03%.(2)The ecological importance types of the study area are relatively average,with a moderately important area of 706.67 km^(2),accounting for 60.85%of the area.(3)The ecological space area of Liangjiang New Area identified in this article is 336.78 km^(2),accounting for about 29%of the research area,the ecological land type is mainly forest land.
