Abstract

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.
