大学校园绿地土壤质量分析与综合评价

On Comprehensive Evaluation and Analysis of the Greenery Plot Soil Quality in Campus

以江苏师范大学泉山校区内3个不同功能区的绿地土壤为研究对象,采用多元统计的主成份分析方法计算得出土壤质量因子4个主成份,再借助SPSS统计软件得出土壤质量指标权重值及其方差极大旋转后主成份因子得分,最后计算综合评价得分。结果表明:该校区绿地土壤质量情况总体上为中等,其中以校园生活区内的绿地土壤质量综合水平最高,实验区次之,教学区最低。

The greenery plot soil of 3 different function areas in Jiangsu Normal University Quanshan campus were studied,4 main constituent of soil quality factors were calculated using multivariate statistical analysis application,besides,the weighing value of the soil quality index and the score of principal component varimax rotation＇s principal component score in virtue of SPSS statistical software,the comprehensive assessment score was calculated finally.The results showed that the soil quality status of the campus is midding in the mass,the score of the soil quality status in the school living quarter is tiptop,the school experimentation section takes the second place,the school teaching section takes the last place.
