城市生态空间生态系统服务功能权衡协同及管控研究——以成都东部新城为例

Research on Trade-Off and Synergistic Relationship of Ecosystem Service and Space Regulation in City Ecological Space:A Case Study of Chengdu Eastern New City

生态功能空间范围划定与主导服务功能识别管控是城市生态功能空间规划的基本前提与首要任务。以成都市东部新城为例,将生态系统服务价值作为衡量生态功能空间存量标准,通过热点分析指标(Gi*指数)划定核心生态功能空间分布范围,同时筛选主导生态系统服务功能所对应的空间落位,识别不同类型的生态功能空间,并据此通过双变量空间局部自相关指数(Local Moran’s I)解读生态系统服务功能间权衡协同机制,尝试提出生态权衡协同视角下生态功能空间的识别与管控新途径,为构建新时期中国新城国土空间规划与生态文明建设提供理论依据。

The demarcation of ecological space and the identification and control of leading service functions are the basic premise and primary task of urban ecological space planning.Taking the Eastern New City of Chengdu as an example,this research takes the ecosystem service value as the standard to measure the ecological space stock,delimits the spatial distribution range of core ecological functions through the hot spot analysis index(Gi*index),and at the same time,the spatial locations corresponding to the dominant ecosystem service functions are screened to identify different types of ecological function spaces.Based on this,the bivariate spatial Local autocorrelation index(Local Moran’s I)was used to interpret the trade-off and collaboration mechanism among ecosystem services,and to try to put forward a new way to identify and control ecological function space from the perspective of ecological trade-off and collaboration,so as to provide a theoretical basis for the construction of new urban land space planning and ecological civilization construction in the new era.
