利用地学信息图谱的江西省生态服务价值结构研究

Study on Structure of Ecosystem Services Value Assisted with Geo-Information Tupu in Jiangxi Province

  • 摘要: 提出了生态服务价值结构的概念,并引入地学信息图谱,以江西省为研究区,利用HJ卫星数据,获得了江西省各县的土地利用类型面积;以修正的生态服务价值估算方法,计算得到了各县6种不同土地利用类型的生态服务价值;利用Weaver组合指数,对江西省县域生态服务价值进行类型划分;将生态服务价值类型与地学信息图谱相结合,使江西省生态服务价值谱系化,依此分析了江西省生态服务价值图谱结构类型特征与组合类型特征,为区域生态环境的可持续发展和构建低碳江西提供了参考建议,为生态经济研究提供了参考。

     

    Abstract: This paper advances a concept of structure of ecosystem service value,introduces geo-information tupu and takes Jiangxi Province as the study area.Firstly,the various types of land use and their areas for each county in Jiangxi acquired by classifying the HJ remote sensing images.Then,the ecosystem service values for six type of land use are calculated by the modified estimation method of ecosystem services value.Thirdly,the ecosystem service values for counties are classified to different types based on the weaver combination index.Finally,combined with ecosystem service value types and geo-information tupu,and ecosystem services values genealogy of Jiangxi province are acquired.The characters of the structures and their combination types of ecosystem service value in Jiangxi province are analyzed following the above procedure,in order to give scientific suggestions for sustainable development of regional ecological environment,Low-carbon Jiangxi establishment,and ecological economy research.
