摘　　要：划定和保护生态空间是提升生态功能和改善环境质量的重要保障。本研究基于生物多样性维护、水源涵养、水土保持等重要性评估和盐渍化、水土流失等敏感性评估结果,开展了特大城市--上海的生态功能重要区域和生态环境敏感区域的空间识别,筛选了适合上海特征和需求的生态空间要素类型,并结合生态空间连续性、稳定性和管理要求,确定了生态空间分布并划分了管控单元。研究结果显示,上海市生态系统重要性和生态环境敏感性均主要处于一般等级,识别并确定的上海市生态空间面积为1879. 20 km2,共包括11种要素类型。全市共划定113个生态空间管控单元,其中80个为一般生态空间管控单元。本研究可为特大城市的生态空间识别以及长三角区域生态空间格局的构建提供重要参考。Delimitation and protection of ecological space is an important guarantee for improving ecological function and environmental quality.Based on the results of importance assessment of biodiversity conservation,water conservation,soil and water conservation and sensitivity assessment of salinization and soil erosion,this study carried out spatial identification of areas of important ecological function and sensitive ecological environment in megalopolis Shanghai,and screened out the types of elements of ecological space suitable for Shanghai's characteristics and needs.According to the requirements of continuity,stability and management of ecological space,the distribution of ecological space was determined and the control units were divided in this study.The results show that the importance of ecosystem and the sensitivity of ecological environment in Shanghai are mainly in the general level.The area of identified ecological space in Shanghai is 1879.20 km2,including 11 types of elements.There are 113 ecological space control units in the city,80 of which are general ecological space control units.This study can provide important reference for the identification of ecological space in mega-cities and the construction of ecological spatial pattern in the Yangtze River Delta region.
