中文摘要以江西省赣州市为研究对象,探索构建了基于地理国情信息的土地资源生态系统服务价值核算体系,并将结果应用于江西省赣州市各县(市、区)土地资源生态补偿优先级的确定中。研究表明:与常规的土地利用分类相比,地理国情信息分类更加细化,能更为精确地核算土地资源生态系统服务价值。赣州市2015年土地资源的生态系统服务价值估算为2 138.89亿元,服务价值从大到小依次为调节服务、支持服务、供给服务和文化服务,且调节服务占比达70.49%。2015年各县(市、区)单位面积土地资源生态系统服务非市场价值最高的是寻乌县,但各县(市、区)不同类型生态服务功能的价值存在差异。从空间分布看,赣州市周边地区生态补偿优先级较高,而中部地区偏低,且单位面积生态系统服务价值偏低的西北部生态补偿优先级也较高。
英文摘要Land resources ecosystem service accounting is the internal requirement of promoting the construction of ecological civilization. Ganzhou City,located in Ganjiang upstream watershed,Jiangxi Province,is an important ecological barrier in Southern China and an important area to maintain the ecosystem health of the Poyang Lake Basin. Taking Ganzhou City as an example,the more suitable table of equivalence factor for Jiangxi area was presented,the method of value equivalent factor in unit area was used,and a service value account of land resources ecosystem was established based on the concept of broad-sense service value of land resources ecosystem. Then the land resources were divided into eight categories: farmland,forest,grassland,desert,bare land,construction land,water area and wetland, and the service value of land resources ecosystem in the form of value was calculated. The value of ecosystem services and its spatial distribution characteristics were applied to determine the priority of land ecological compensation for land resources in various counties, which provided reference for the application of geographic census data in the calculation of ecosystem services value of land resources. The results showed that compared with the conventional classification based on land use,the classification based on geographical national conditions was more refined for the land resources ecosystem services value can be more accurately calculated; in 2015,the total service value of Ganzhou land resources ecosystem was assessed at RMB 213.889 billion yuan,its order from big to small was regulating service,support service,supply service and cultural service,and the regulating service value took 70.49% of all the assets; in 2015,among all the counties,cities and districts,the county of Xunwu had the highest ecological service value per unit area,and all types of ecological service value varied in different regions. Analyzed from the spatial distribution,the ecological compensation priority in the surrounding areas of Ganzhou was relatively high,while the priority in the central areas was low. The northwestern areas had relatively high ecological compensation priority although their ecosystem service value per unit area was comparatively low.
