县域尺度下生态系统服务供需匹配及生态建设——以陕西省为例

Matching Supply and Demand of Ecosystem Services and Ecological Construction at County Scale:Take Shaanxi Province as An Example

利用生态系统服务价值量、社会经济数据,并通过标准化及冷热点等方法分析了陕西省所有县级行政单位ES供需的数量匹配和空间匹配特征,并以匹配结果为依据,划分生态建设类型,提出针对性的建设措施。结果表明:陕西省各县市ES供给和需求均存在明显的空间分异特征,且各评价单元匹配关系较差,其中空间关系表现出明显的供需冷热点空间错位特征,数量匹配一致性也较差。基于评估结果,将陕西省划分五类生态建设区域,并针对各区域供需特征及匹配关系,从生态、产业、人口等方面针对性地提出建设与管理措施。

Based on the value of ecosystem services,social and economic data,and through the methods of standardization and cold and hot spots,this paper analyzes the quantitative matching and spatial matching characteristics of ES supply and demand in all county-level administrative units in Shaanxi Province,and based on the matching results,divides the types of ecological construction,and puts forward the corresponding construction measures.The results show that:The supply and demand of ES in all counties and cities of Shaanxi Province have obvious spatial differentiation characteristics,and the matching relationship of each evaluation unit is poor,among which the spatial relationship shows obvious spatial dislocation characteristics of cold and hot spots of supply and demand,and the consistency of quantity matching is also poor.Based on the evaluation results,Shaanxi Province is divided into five types of ecological construction areas,and according to the regional supply and demand characteristics and matching relationship,construction and management measures are put forward from the aspects of ecology,industry and population.
