摘　　要：识别区域生态系统服务簇及其结构模式,是揭示人地系统客观规律的前提和基础。基于中国气候区划、农业自然区划和主体功能区划成果和三级流域单元,并遵循统一性、一致性、区域共轭性等规律,坚持尽可能保持自然与行政边界完整性的原则,对广东省陆域进行自上而下为主的地域区划,以最大化保持流域单元和生态系统的完整性;按照区划单元测算粮食供给、原料生产、水资源供给等12项区域典型生态系统服务价值量和z-score分值,最后运用K-均值聚类法,进行生态系统服务簇与模式识别。得到以下结果:广东省陆域涵盖中亚热带、南亚热带和边缘热带3个自然地带,可划分为9个经济片区共34个自然的流域单元,形成了“3+9+34”的三级地域区划方案;识别出水文调节保护型、水土保持调节型、生态保育公园型、生态宜居和谐型、综合协调供给型共5类生态系统服务簇的结构模式,展示出广东省陆域生态系统服务簇以珠三角为核心的空间对称分布模式;受地形、地貌等自然地理环境和土地利用等人类活动的影响,不同区域生态系统服务簇各具独特的地形和地理特征,承担着的生态系统服务功能各异。基于这些结果,研究提出生态系统服务簇模式的差异化生态系统管控措施,为省域国土空间规划的实践提供研究支撑。The effective and systematic identification of the regional ecosystem service clusters and structural patterns is prerequisite and foundation for revealing the objective laws of human-earth system.Based on the results of climatic zoning,agricultural natural zoning,major functional zoning division,and three-level watershed unit in China,the land area regionalization of Guangdong Province was carried out from top to bottom following the rules of unity,relative consistency,regional conjunction and the principle of maintaining the integrity of natural and administrative boundaries as far as possible to maximize the integrity of watershed units and ecosystems.The values and z-score of 12 typical ecosystem services such as grain supply,raw material production,and water resource supply were calculated according to the zoning units.Finally,the K-means cluster method was applied to identify ecosystem service clusters and patterns.The results are as follows:the study area covered three natural zones,namely the middle subtropical zone,the south subtropical zone and the marginal tropical zone,and was further divided into nine economic zones with a total of 34 watershed units,forming a three-level zoning system of“3+9+34”.Five types of ecosystem service cluster structure patterns were identified to objectively demonstrate the symmetrical spatial distribution characteristics of terrestrial ecosystem services in Guangdong Province with the Pearl River Delta as the core,which include hydrologic regulation and protection type,soil and water conservation regulation type,ecological conservation park type,ecological livable and harmonious type,and comprehensive coordinated supply type.Affected by terrain,landform and other natural geographical environment as well as human activities such as land use,each region of ecosystem service cluster type has its own unique terrain and geographical characteristics and undertakes different ecological service functions.Based on the research results of recognition and analysis of ecosystem se
