基于生态系统服务供需关系的国土空间生态修复分区研究——以云南省为例

Study on zoning for ecological remediation of territorial space based on the ecosystem services supply and demand:A case study of Yunnan Province

以云南省为研究区,通过量化生态系统服务供给与需求水平,分析二者匹配关系,研究全省县域尺度的生态保护与修复分区。结果表明,生态系统服务供给与需求存在空间异质性,二者空间上整体表现为互补关系。滇西北和滇西南林区是高供给区,滇东城镇化较为发达地区是低供给区和高需求区。依据供需特征,将云南省分为4个区域,供需协调型(高供给-高需求),应重点提高除水域外其他生态用地供给水平;城乡重构型(低供给-高需求),应重点关注城市绿地空间配置及覆盖;重点修复型(低供给-低需求),在局部地区开展水土保持、矿山修复等修复工程;生态保育型(高供给-低需求),以生态保育为主要目标,实现森林质量的整体提升。

Taking Yunnan Province as the research area,the ecological protection and restoration zoning work at the county level was carried out by quantifying ecosystem service(ES)supply and demand and mapping the matching relationship between the two.The re⁃sults showed that obvious spatial heterogeneity was seen in both ES supply and demand,and these two showed a complementary rela⁃tionship spatially.The forest areas in the northwest and southwest Yunnan were high supply areas,while the eastern parts were low supply and high demand areas.The Yunnan Province was divided into four regions according to the characteristics of supply and de⁃mand:coordination type(high supply-high demand),which should focus on improving the supply level of other ecological land ex⁃cept water areas;urban and rural remodeling type(low supply-high demand),which should pay more attention to the spatial alloca⁃tion and coverage of urban green space;key restoration type(low supply-low demand),which should carry out soil and water conser⁃vation,mine rehabilitation and other rehabilitation projects in local areas;ecological conservation type(high supply-low demand),which should take ecological conservation as the main goal to achieve the overall improvement of forest quality.
