长春师范学院校园土壤研究

对长春师范学院校园内的土壤进行理化性质分析,发现第一食堂、学生第八公寓和第一教学楼路旁土壤的自然含水量和有机质含量低于人工林地和校园草坪土壤。家属区人工菜园土壤有机质含量较高,与居民人工施肥有关。从长春师范学院校园不同取样点土壤的垂直剖面来看,土壤亚表层的有机质低于表层土壤,但是自然含水量高于表层土壤。从整体来看土壤的pH值呈中性,各样点差别并不明显。长春师范学院的校园土壤污染加重,应采取相应措施进行防治。

Study on the Campus Soil of Changchun Normal University

The soil of Changchun Normal University is gathered and tested.The results show that the soil moisture and organic content of the student canteen,the eighth apartment building and the first student building are less than the ones of forest and lawn.The organic content of soil is higher in the garden in front of inhabitant building because it may be fertilized by the inhabitants.From the vertical section of soil,it is found that organic matter content is less than the surface while soil moisture is reverse.The PH value of soil is neutral in Changchun Normal University,but the difference in various places is not obvious.The soil pollution of Changchun Normal University is becoming more and more serious,therefore some measures should be put forward to prevent and deal with this problem.
