摘　　要：新型城镇化是我国新时期社会经济发展的重大战略,城镇化进程带来的资源与环境需求对新时期水土保持工作提出了高质量发展的要求。深圳市作为高度城镇化地区,长期引领城市水土保持工作,但并未形成适合自身高密度经济单元、高科技产业类型、高质量环境要求的水土保持区划。以深圳市为研究对象,通过数理统计方法构建了水土保持区划指标体系;基于层次聚类分析和地理信息系统(GIS)空间叠加分析等定量手段和定性修正,划定了以最低行政层级的街道为基本单元的水土保持区划方案,并针对各分区水土流失特征与经济社会发展定位,提出了区域化水土流失防控重点和策略。区划方案与城市空间扩张、内部功能调整形成的格局一致,充分体现了深圳市城市水土保持特色,可用于指导深圳市水土保持分区审批、分类管理、分级防控,进而为实现深圳新时代的历史使命提供支撑。New urbanization is a crucial strategy for China’s economic and social development in the new era.The increasing demands for environments and resources resulting from urbanization necessitate a focus on high-quality development in the field of soil and water conservation.Shenzhen,as a highly urbanized area,has been at the forefront of urban water and soil conservation efforts.However,there is a lack of suitable regionalization that accounts for its high-density economic units,high-tech industries,and high-quality environment.An index system is established for soil and water conservation regionalization using mathematical statistical methods.By employing hierarchical cluster analysis and GIS spatial superposition analysis,a regionalization scheme based on street level,which represents the lowest administrative level,is delineated.Additionally,major measures and strategies for preventing and controlling soil and water loss in each region are proposed in consideration of the characteristics of soil and water loss as well as the orientation of economic and social development.Importantly,the regionalization scheme aligns with the prevailing pattern of urban space expansion and internal function adjustment.These results can serve as guidance for regionalization approval,classified management,and hierarchical prevention and control of soil and water conservation in Shenzhen.
