摘要
在野外考察、GPS定点和土壤采样分析的基础上,运用统计特征值、相关分析等方法,以格达良乡为例分析了阿图什市盐渍化土壤中有机质现状及有机质与盐分之间的相关性,并对耕地土壤有机质分级.结果表明,格达良乡耕地区有机质含量大于荒地区;除荒地有机质在0～15cm土层属强变异性以外,无论是荒地还是耕地,各个土层的变异性属中等变异性.通过对耕地土壤样品分析结果的统计,全乡耕地土壤有机质含量范围在0.517%～3.331%之间,平均值为1.79%;土壤有机质评价为4级的耕地,属较缺型.对于有机质与盐分之间的相关性分析,荒地区表层有机质含量与Mg2+含量达极显著相关;耕地区不管哪个土层、哪个因素之间的相关性都不显著.
Based on the field survey,GPS and soil sampling,organic matter of salinity soil and correlation between organic matter and soil contents in Atux city and classified soil organic matter of cultivated land were analyzed with statistical characteristic value and correlation analysis method.Result shows that the organic matter content of cultivated land area is larger than that of waste area.Except for that 0 15 cm soil layer of waste area belongs to strong variability,the organic matter of other layers of wast land or cultivated land belong to medium variability.Through the statistic value of soil samples of gedaliang,the soil organic matter of cultivated land area in town ranges from 0.517% to 3.331% with the average value 1.79%.Through the correlation analysis between the salt and organic matter,the organic matter is remarkably correlated with Mg^2＋ in surface area of waste land,but in cultivated land area,the correlation is not significant.
