摘要
生态保护重要性评价是国土空间规划体系中“双评价”工作的重要组成部分,是区域农业生产、城镇建设协调发展的基础保障。以武汉都市圈为例,利用遥感数据作为主要的数据来源,基于生态系统服务功能重要性和生态敏感性评价模型,结合生态斑块集中度,构建生态保护重要性评价体系,划分生态保护重要性等级。结果表明,武汉都市圈生态保护极重要区面积为1.86万km^(2),占武汉都市圈总面积的32.02%;生态保护高度重要区面积为1.94万km^(2),占武汉都市圈总面积的33.46%;生态保护极重要区和高度重要区主要分布在东部的大别山脉和南部的幕阜山脉等生态系统服务功能极重要且生态极敏感的地区。该研究可以为区域生态空间和生态保护红线的的优化提供数据支撑,对武汉都市圈的绿色发展、生态保护具有重要的参考价值。
The evaluation of ecological protection importance is an important component of the"dual evaluation"work in the national spatial planning system,and is the basic guarantee for the coordinated development of regional agricultural production and urban construction.Taking the Wuhan metropolitan area as an example,remote sensing data is used as the main source of data.Based on the importance of ecosystem service functions and ecological sensitivity evaluation models,and combined with the concentration of ecological patches,an ecological protection importance evaluation system is constructed to classify the importance levels of ecological protection.The results show that the area of the extremely important ecological protection zone in the Wuhan metropolitan area is 18600 km^(2),accounting for 32.02%of the total area,and the area of the highly important ecological protection zone is 19400 km^(2),accounting for 33.46%of the total area.The extremely important and highly important ecological protection zones are mainly distributed in areas with extremely important ecosystem service functions and ecological sensitivity,such as the Dabie Mountains in the east and the Mufu Mountains in the south.This study can provide data support for the optimization of regional ecological space and ecological protection red lines,and has important reference value for the green development and ecological protection of the Wuhan metropolitan area.
