摘要
基于武汉市黄陂区野佛沟径流场监测的径流和泥沙数据,通过类比法建立土壤流失量的预测模型,完成了从土壤流失监测到土壤流失预测研究的重大突破,为该类型区生产建设项目水土流失背景值的预测提供依据。同时对径流场监测的径流和泥沙数据进行统计分析,结果表明:土壤流失量的大小与降雨强度有着密切关系,其值的大小受环境因素的影响远比径流深度的影响复杂。
According to the runoff and sediment data of Yefogou Runoff Field in the Huangpi district in Wuhan city,we can establish the prediction model of soil loss rate in analogy,so as to provide foundation for the prediction of the background value of soil and water loss in the production and construction project areas which are located in Huangpi district.An important breakthrough that from monitoring to prediction in soil loss has come true on account of the prediction model in this area.Meanwhile,the runoff and sediment data from the survey in runoff field are input to statistical analysis,whose result shows that the rate of soil loss is bound up with the rainfall intensity,and its amount is more complexly influenced by environmental factors than runoff depth.
