为了探究好水川流域坡面产流产沙规律,以该流域11个观测点的土壤含水量、土壤渗透系数和土壤容重数据为基础,通过极差法对数据进行标准化处理,运用模糊聚类分析模型对坡面11个土壤观测点进行聚类分析。结果表明:流域土壤观测点可分为7个种类,聚类分析可直观地再现流域坡面土壤的差异性,有效提高坡面土壤的观测效率。
In order to explore the law of runoff and sediment yield in the watershed, the data of soil water content, soil permeability coefficient and soil bulk density at 11 observation points in this basin were used as the basis to standardize the data by using the range method. By using fuzzy clustering analysis model Cluster analysis was conducted on 11 soil observation sites on the slope. The results show that the soil observation points in the basin can be divided into seven categories. Cluster analysis can directly reflect the difference of the soil on the slope and improve the observation efficiency of the soil on the slope.
