摘要
水土流失动态监测是落实国家生态文明建设决策部署的重要支撑。中国土壤流失方程(CSLE)被用于水土流失动态监测中水蚀区的土壤侵蚀模数计算,但其中各因子计算方法和参数取值因地而异。采用文献法对重庆市CSLE模型各因子的相关研究进行了检索,系统梳理和归纳了各因子的计算方法及参数取值等相关研究成果,提出了研究中存在的问题及未来研究的方向,希望能为重庆市水土流失动态监测及水土保持工作提供一定的帮助和参考。
Dynamic monitoring of soil and water loss is an important support for the implementation of the decision and deployment of the national ecological civilization construction. Chinese Soil Loss Equation(CSLE) is used for the calculation of soil erosion modulus in water erosion area for dynamic monitoring of soil and water loss,but the calculation method and parameter value of each factor vary from place to place. The paper retrieved the relevant researches of CSLE model factors in Chongqing by using the literature method,systematically summarized the calculation methods and parameter values of each factor and put forward the existing problems and future research directions,hoping could provide some help and reference value for soil erosion dynamic monitoring and soil and water conservation of Congqing municipality.
