不同使用功能区土壤酸碱性的对比分析研究

Comparative Analysis of Soil Acidity and Alkalinity in Diff erent Functional Areas

本文对长沙市某大学校园内外的耕地、林地以及景观园林等不同功能区的土壤pH值进行了测定。结果显示:土壤pH值整体偏酸性。耕地、林地和景观园林的pH值大小排序为:景观园林>林地>耕地;下层土壤(10~20 cm)pH值低于表层土壤(0~10 cm)pH值;靠近公路的功能区土壤pH值均低于远离交通区域的土壤pH值。

The pH values of soils in different functional areas,such as farmland,woodland and gardens,were measured on and off a university campus in Changsha,China.The results showed that the pH value of the whole soil was slightly acidic.The pH values of cropland,woodland and landscape were as follows:Landscape>Woodland>cropland;lower soil(10~20 cm)pH value was lower than surface soil(0~10 cm)pH value;The soil pH value near the highway is lower than that far from the traffic.
