摘要
根据深圳市水土流失调查资料和产沙观测数据,通过选取影响水土流失的主要因子:地形、植被、降雨、土壤、城市化人为影响因子等,建立了符合深圳地区的多元回归方程,其中城市化人为影响因子是根据城市水土流失现状提出的,并通过深圳3个水保试验站的调查资料反推求得。通过两组实测资料检验,表明建立的模型具有较高的精度,能够较好的反映深圳地区的水土流失特点。
According to the survey data of soil erosion and measured water and soil loss in Shenzhen City,the key factors associated with soil and water loess,namely landform,vegetation,rainfall,soil and urbanization artificital element,were collected and an empirical model was established based on these factors.The factor of urbanization artificial element was obtained from the meadured data from 3 local stations in Shenzhen City.The precision of the prediction model was tested by two sets of measured data,showed that it has a high precision and can represent the characteristics of soil erosion in Shenzhen City.
