伊犁河谷不同土地利用方式下土壤粒度特征
Characteristics of Soil Grain Size in Different Land Use Patterns in the Yili River Valley
摘要
Abstract
Ninety-eight soil samples were obtained from 14 soil profiles in different land use patterns in Xinjiang Yili River Valley area in order to guide the sustainable development of water and soil environment.Grain sizes of sample were determined by the EASY SIZER20.Fokker ward formula was used to calculate the median,the average particle size,standard deviation,kurtosis and skewness.The data were analyzed and mapped by using Excel and SPSS 19.0 statistical software.The results show that:(1) soil particle grade percentages of different land use patterns are different,but silt (2～50μm) and sand (50～2 000 μm) are the dominant particles.Contents of silt and sand in cultivated land are higher than those in wasteland,contnet of clay (＜2 μm) in the woodland is generally larger than that in the grassland;(2) coefficients of variation of soil particle sizes of different land use patterns are significantly different,the coefficients of variation of silt and sand contents in cultivated land are greater than those in wasteland,the coefficient of variation of clay content is opposite;(3) soil grain size characteristics of different land use patterns are different,the average particle size of cultivated land is significantly larger than that of grassland,wasteland and woodland.The sorting of wasteland is obviously better than that of the cultivated land and garden land.关键词
