不同土地利用方式土壤理化性质的月际变化——以滇池柴河流域为例

Monthly Variations in Physical and Chemical Properties of the Soil under Different Land Use Patterns—A Case Study of the Chaihe River Basin of Lake Dianchi

以滇池柴河流域为研究区域,对设施农业、传统农业、坡耕地、撂荒地和林地等5种土地利用方式的土壤理化性质进行了逐月监测.结果表明:不同月份,各种土壤的理化性质在不同土地利用方式间的显著性差异不尽一致.各月平均下,不同的土地利用方式,其土壤的理化性质存在显著性差异(P<0.05),但不同土壤理化性质在不同土地利用方式间的显著性差异存在差别.因此,应加强不同土地利用方式土壤理化性质的连续监测,以全面掌握土壤理化状况.

Taking Chaihe river basin of Lake Dianchi as a study area,we conducted a monthly monitoring of physical and chemical properties of the soil for facility agriculture,traditional agriculture,in slope farmland,abandoned land and woodland. The result shows that significance level of physical and chemical properties of the soil under different land use patterns varies by month.In different months,under different land use patterns,there exists significant difference in physical and chemical properties of the soil(P <0.05).To fully grasp the physical and chemical properties of soil under different land use patterns.continuous monitoring should be strengthened.
