By analyzing soil quality of 4 kinds of land use types in Kalamay agriculture development area according to principal component analysis, we draw the conclusions: nature shrub tree land is affected little by mankind, a great deal of organic matter return to soil every year, and root system can improve soil physical quality, can absorb salt from soil, so the soil quality of nature shrub tree land is the best; the soil quality of farmland is better than the soil quality of manpower Tamarix Bulrush land, which may be reasoned that man make for soil quality by irrigation to exclude salt and fertilizing organic muck in the earlier oasis digging up period. Soil physical qualities of tree land get harden and worsen for flooding irrigation, furthermore climate in Kalamay is dry and rainless , the other irrigation is very long time after the former one, so soil get harden severity and result soil physical quality get worse and worse.

利用主成分分析法分析新疆克拉玛依农业开发区四种土地利用方式下的土壤质量，得出：天然灌木林地，受人为影响较小，每年有大量有机物质返还土壤，且天然灌木的根系可以很好的改良土壤的物理性质，同时所选天然灌木林灌木多是耐盐碱并且本身又具有吸收积累来自土壤的盐分，土壤质量最好；农田受到的人为影响最大，但农田综合得分却好于人工柽柳芦苇地综合得分，这可能是由于在开垦初期的绿洲农田，受到了人们灌水压盐及增施各种有机无机肥料等有利于土壤质量提高的措施所致；乔木林地，由于人们用大水漫灌的方式灌溉，致使林地土壤变得板结，土壤物理性质下降，加上克拉玛依地区气候干燥少雨，一次灌溉后较长时间后才有下一次灌溉，致使土壤理化性质恶化，土壤质量不高。
