国家森林城市的建立是为了调节城市气候，实现城乡一体化发展。研究了珠三角城市群NFC建设前后生态系统支持服务与调节服务的变化及其相互关系。采用InVEST模型和CASA模型对5种生态系统服务功能（ESs）进行了评价，并利用相关分析分析了生态系统服务功能之间的关系。结果表明：(1)2005 - 2020年建设用地显著增加，耕地减少最多，林地次之；(2) 2005 ~ 2020年珠三角地区除NPP外，其余ESs均呈下降趋势。(3)支持服务与调节服务之间存在协同关系，其内部服务呈正相关关系。本研究证明了支持服务对调节服务的保障作用，我们发现NFC的构建可以抑制ESs的下降。在此基础上，提出了以自然为本的森林城市发展对策。
The establishment of national forest city (NFC) is to regulate the urban climate and realize the integrated development of urban and rural areas. We explored the changes and relationships between ecosystem supporting services and regulating services before and after the construction of NFC in the Pearl River Delta urban agglomeration (PRD). InVEST and CASA models were used to evaluate five ecosystem services (ESs), and correlation analysis was used to analyze the relationship between ESs. The results showed that (1) Construction land increased significantly from 2005 to 2020, while cultivated land decreased the most, followed by woodland. (2) All ESs except NPP decreased from 2005 to 2020 in the PRD. (3) There was a synergistic relationship between supporting service and regulating service, and their internal services are positively correlated. This study proved the guaranteed effect of supporting services on regulating services, and we found that the construction of NFC can restrain the decline of ESs. Based on the above results, we proposed nature- based solutions for the development of forest cities.
