摘要
土壤溶解有机碳是当前环境学的研究热点之一。从土壤溶解有机碳的空间变化的角度出发,研究了果树在岩溶区与非岩溶区土壤溶解有机碳的表现。结果表明,不同区域、不同树种、不同取样深度的土壤溶解有机碳的含量均不同,非岩溶区、20cm的土壤溶解有机碳含量较岩溶区、50cm为高,不同树种在不同区域不同深度有不同的表现。低pH对应较高的土壤溶解有机碳含量。
Dissolved organic carbon （DOC） in soil is one of the present research focuses. DOC was response to the different fruit trees in Karst and non-Karst area. the results showed the contents of soil DOC were different in different areas, trees and depth of soil.The contents of DOC in depth of 0-20cm in non-Karst area were higher than that in Karst area, whereas different in the depth of 20-50cm. Lower pH had made DOC increased in soils.
