基于“三线一单”的珠海市生态空间识别研究

Ecological space identification of Zhuhai City based on“three lines and one order”

基于“三线一单”编制技术指南要求,选取珠海市作为研究区域,开展生态空间识别研究,探索生态空间识别技术流程和方法。通过系统评估区域生态系统服务功能,叠加生态保护红线及各类重点保护区域,统筹协调区域经济社会发展空间,识别并划定珠海市生态空间面积334.16 km^(2),占全市陆域面积的19.23%,主要分布在香洲北面的凤凰山、大镜山水库集中区、斗门区的黄杨山以及沿海山地等区域,与珠海市生态安全格局基本保持一致。

Based on the requirements of the“three lines and one order”technical guide,this study selected Zhuhai City as the study area,carried out research on ecological space identification,and explored the technical process and methods of ecological space identification.Through the evaluation of regional ecosystem services function,we superimposed ecological red line and various key protected areas,coordinated regional economic and social development space,identified and demarcated Zhuhai s ecological space area of 334.16 km^(2),accounting for 19.23%of the land area of the city,which is mainly distributed in Phoenix Mountain in the north of Xiangzhou District,Dajingshan Reservoir concentration area,Huangyang Mountain in Doumen District,coastal mountains and other areas.It is basically consistent with the ecological security pattern of Zhuhai city.
