生态系统服务价值评估及其时空差异研究--以九龙江流域为例

Evaluation of ecosystem service value and its spatio-temporal differences--Taking the Jiulong River Basin as an example

以九龙江流域为例,估算了九龙江流域生态系统服务单位面积价值和总价值,并采用Geoda软件分析流域范围内各县市生态系统服务价值的时空差异特征.结果表明:2019年九龙江流域生态系统服务价值为1759.4981亿元.水域的生态系统服务最为显著;生态系统服务价值在时间分异上起伏较大,但空间上表现较为稳定,并具有联动效应和聚类特征;生态系统服务价值及其单位面积价值高值区基本分布在上游地区,低值区主要分布在下游城市群.

A taking jiulong River Basin as an example,the unit area value and total value of ecosystem services in jiulong River Basin were estimated,and the spatial and temporal differences of ecosystem services value among counties and cities in jiulong River Basin were analyzed using Geoda software.The results showed that the value of ecosystem services in jiulong River Basin region in 2019 was 175.94981 billion yuan.The ecosystem service of water area is the most significant.The value of ecosystem services fluctuated greatly in time differentiation,but remained stable in space,and had linkage effect and clustering characteristics.The high value of ecosystem service value and its unit area value were mainly distributed in the upstream region,while the low value was mainly distributed in the downstream urban agglomeration.
