摘　　要：据t检验法结合主成分分析法,对比筛选出适合新疆于田-若羌绿洲带用于刑侦搜查的土壤特征元素。结果表明:研究区16种土壤特征元素CaO,MgO,Na_(2)O,Ba,Zr,Sr,I,Cr,Hg,B,As,Cu,Zn,Br,Sc和Li的含量信息可用于区分于田-若羌绿洲带4个地区不同土壤特征。基于此,将统计的土壤类型信息、地形地貌信息、地理坐标信息及特征元素信息等,作为于田-若羌绿洲带土壤元素特征数据库建立的参考依据,进而提高刑侦搜查效率。By combining T-test with principal component analysis,the soil characteristic elements suitable for criminal investigation and search in the Yutian-Ruoqiang Oasis Belt of Xinjiang were compared and screened.The results showed that the content information of 16 soil characteristic elements CaO,MgO,Na_(2)O,Ba,Zr,Sr,I,Cr,Hg,B,As,Cu,Zn,Br,Sc,and Li in the study area can be used to distinguish the characteristics of different soils in the four regions of the Yutian-ruoqiang oasis belt.Based on this,the soil type information,terrain and geomorphology information,geographic coordinate information,and feature element information collected will be used as a reference for establishing a soil element feature database in the Yutian-Ruoqiang Oasis Belt,thereby improving the efficiency of criminal investigation and search.
