文章论述了昆明马料河水环境综合整治项目区域及其工程概况,水土流失预测范围、时段、方法和结果。水土流失预测结果:工程建设期和自然恢复期产生的水土流失总量为52396.26 t,新增水土流失量为51681.88 t。诱发水土流失的区域包括河道区、绿化景观区和淤泥干化场区。主要因素是工程施工扰动破坏地表,弃渣和临时堆存表土引起的水土流失,属典型人为加速侵蚀。
The article discusses the general situation of Kunming River water environment improvement project area and its engineering, soil erosion prediction range, time, methods and results. Prediction results of soil and water loss: The total amount of soil and water loss during the construction period and natural recovery period is 52,396.26 t, and the amount of new soil and water loss is 51,681.88 t. The areas where water and soil loss are induced include river area, landscape area and mud drying area. The main factor is soil erosion caused by construction disturbance disturbing surface, spoil and temporary storage of surface soil, which is a typical man-made accelerated erosion.
