Abstract：In the preparation of soil and water conservation plans,the predicted amount of soil and water loss in different conservation zones is an important basis for determining the focus of soil erosion prevention and control and for arranging conservation measures.At present,most production and construction projects have not conducted research and analysis on the impact scope of soil erosion and whether sediment and runoff are exported beyond the project area,which affects the implementation of soil and water conservation monitoring.The absence of impact area analysis leads to unreasonable arrangements of conservation measures during the planning stage and hinders the implementation of relevant monitoring requirements during the monitoring stage.By comparing and analyzing different regulations and requirements on soil and water loss prediction and monitoring,and taking a city park construction project as an example,an analytical approach for soil and water loss impact areas in point-type production and construction projects is proposed.By analyzing the direction of runoff and sediment within the project area,the internal and external impact areas of soil and water loss are determined,clarifying the occurrence periods,harmful effects,and final destinations of soil erosion in different areas.On this basis,the key areas for soil and water loss control in the project are identified,achieving the goals of hazard-based prevention and targeted measures.
