生态空间发挥着维持区域生态平衡的功能,其范围识别与评估是实现区域可持续发展的关键.以青岛市为例,系统构建了生态系统服务功能和生态敏感性评级指标体系,利用GIS和RS技术,对青岛市生态空间进行定量识别,将识别结果与土地利用状况结合分析.得出结论如下:(1)青岛市生态空间面积为10 989.22 km2,占青岛市国土面积的97.31%,其中核心型、辅助型和过渡型生态空间面积分别为 735.17km2、3 069.44 km2和 7 184.61 km2,分别占研究区面积的 6.51%、27.18%和 63.62%.(2)对生态用地利用类型统计发现,90%左右的建设用地处于生态空间范围内.本研究可为区域国土规划和生态空间优化布局提供参考,并为相关研究提供经验借鉴.
Ecological space plays the role of maintaining regional Balance of nature,and its scope identification and assessment is the key to achieve regional sustainable development.Tak-ing Qingdao city as an example,a system of ecosystem service functions and ecological sensitiv-ity rating indicators was constructed.GIS and RS technologies were used to quantitatively iden-tify the ecological space in Qingdao city,and the identification results were combined with land use conditions for analysis.The conclusion is as followings.(1)The ecological space area of Qingdao city is 10 989.22 km2,accounting for 97.31%of the total land area of Qingdao city.The core,auxiliary,and transitional ecological space areas are 735.17 km2,3 069.44 km2,and 7 184.61 km2,respectively,accounting for 6.51%,27.18%,and 63.62%of the research area.(2)According to statistics on the types of ecological land use,about 90%of construction land is within the scope of ecological space.This study can provide reference for regional land planning and ecological space optimization layout,and provide experience for relevant research.
