摘要
通过对塔里木盆地南缘克里雅河流域于田地区典型盐渍化区域进行多次野外调研,在GPS定点,土壤采样及室内分析的基础上,借助Excel、SPSS等统计软件对研究区不同时期总可溶性盐进行分析比较,得出该区存在明显季节性积盐,并通过CAC>1,得出相同结论。对土壤进行分类,该区均属于氯化物和硫酸盐氯化物型土壤。在地下水埋深一定范围内,分析了各样点的土壤含盐量和地下水矿化度的关系,相关关系显著。特别地对该区9月的土壤盐分组成状况进行分析,并有针对性地提出该区的土壤改良措施,有效的配制冬灌用水定额。
The field survey were conducted on typical salinized land in Yutian area, southern part of Tarim Basin.By means of SPSS statistical software, soil total dissolved salt content were analyzed in different period in this region. Results showed that：the region being obvious seasonal salt plot,and CAC〉1 can get the same result. The soil in the region belongs to chloride and sulfate chloride type by the soil classification. The relationship between soil salt cotent and ground water mineralization in different samples was analyzed and was found to be remarkable. The soil salt content was specially analyzed in September. Finally, some countermeasures for improving salinized soil were put forward.
