| 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。 |
| 关 键 词： | 土壤溶解有机碳 果树 岩溶区与非岩溶区 |

| Abstract: | 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. |
| Keywords: | Soil dissolved organic carbon Fruit tree Karst and non-Karst area |
