基于生态功能区划理论的市域生态功能区划探讨——以曲靖为例

The Ecological Function Zoning Based on Urban Ecological Theory—A Case Study of Qujing,Yunan Province

曲靖自1997年撤地设市以来,经济迅速发展,亟需一个合理的生态功能区划方案。在对生态功能区划理论研究的基础上,采用基于主导标志的顺序划分合并法和基于要素叠置的类型制图法将曲靖划分为3个区:经济文化密集区、生态协调区(包含5个生态亚区)、生态支持区(包含1个生态敏感支持功能亚区和1个生态脆弱型支持功能亚区)。认为实现可持续发展需在协调各生态功能区的同时,还应充分认识到该区域的生态异质性,充分发挥各功能区的作用功能,通过功能单元的异质性和多样性维持和提升区域的生态稳定性。

The economic of Qujing has developed rapidly,ever since it become a municipal city in 1997,needs a reasonable ecological function regionalization scheme. Based on study of urban ecological theory,sequence division and merging method based on the order of dominant symbol and type mapping method based on elements superimposed were adopted to divide Qujing into three regions： economy / cultural leading zone,environmental regulating zone（ containing five ecological subregions） and ecological supporting zone ecological coordination zone（ containing five ecological subregions）,ecological support zone（ containing an ecologically sensitive support subregion and ecologically fragile type support functional subregion）. It was thought that realizing the sustainable development,need the coordination of various ecological function areas at the same time,also should fully realize the ecology of the region heterogeneity,give full play to the role of the function in each functional area,through heterogeneity of functional units and diversity maintaining and enhancing regional ecological stability.
