The research of the composite index number ( Qi) of soil quality in different utilizing ways suggests that, Qi of forest plantation is obviously higher, whereas qi of sloping cultivated land is the lowest. 不同利用方式下土壤质量综合指数(QI)研究表明:人工林的QI值显著偏高,坡耕地的QI值最低。
The research of the composite index number ( PI) of soil quality in different soil locations suggests that, the soil quality index increases as the altitude of mountain slope location decreases. 山体坡面不同坡位下土壤质量综合指数(PI)研究表明土壤质量指数随山体坡面位置相对海拔高度的降低而增高。
Therefore, this pre-selection from the Shanghai and Shenzhen Composite Index and a number of units, ready to start the two-pronged empirical research. 所以本文预选取沪深综指和一些个股,准备从两个方面入手展开实证研究。
