| 分析生态系统服务的影响因子是管理生态系统并提出规划建议的基础。本研究基于InVEST模型量化广东省乡镇尺度的4种生态系统服务。结果表明，广东省各生态系统组成呈“三增两减”变化趋势，不同用地生态系统占比不同；可根据区域需求通过改变用地占比改变生态系统服务占比，进而优化区域生态系统服务。 |

| Abstract: |
| 【Objective】Guangdong Province, which has high intensity human economic activities, needs fine-scale ecosystem services research, which is the basis for managing multiple ecosystems at the same time and making specific planning recommendations. This study chooses township scale research. 【Method】In this study, the InVEST model was used to quantify four kinds of ecosystem services in Guangdong Province at the township scale. Four types of ecosystem services were selected to evaluate water yield, carbon storage, soil conservation, and habitat quality. All data are unified at a resolution of 30 m.【Result】The ecosystem composition of Guangdong Province showed a trend of ‘three increases and two decreases’, and the proportion of different land use ecosystems was different. According to the regional demand, the proportion of different ecosystem services can be changed by changing the proportion of land use, so as to optimize the regional ecosystem. |
