纳板河流域不同土地利用类型下土壤综合肥力分析
Integrated Soil Fertility Quality Analysis under Different Land Use Types in Naban River Watershed
摘要
Abstract
Soil physical and chemical properties of 38 topsoil (0 ~20 cm) samples collected from 6 types of land use (forest,mixed forest,maize,tea,paddy,rubber) at Naban River Watershed National Nature Reserve in Yunnan Province were tested to study the effect of land use type on soil quality by the method of soil quality index.Based on correlation analysis,the integrated soil quality indices of major land use were calculated with 5 indicators including soil organic matter,total nitrogen,available phosphorus,available potassium and pH.Results indicated that there was obvious difference of soil quality index among 6 vegetation types,and the order of integrated soil quality index was as follows; forest (64.30) > mixed forest (60.66) > tea (57.09) > maize (52.66) > rubber (41.49) > paddy (35.81).关键词
