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。
Soil dissolved organic carbon is one of the hot topics in current environmental studies. From the perspective of spatial variability of dissolved organic carbon in soils, the effect of fruit tree on soil dissolved organic carbon in karst and non-karst areas was studied. The results showed that the contents of soil dissolved organic carbon in different regions, different tree species and different sampling depths were different. In the non-karst area, the content of dissolved organic carbon in 20cm soil layer was higher than that in karst area and 50cm depth. Different tree species differed in different depths Performance. Low pH corresponds to higher soil dissolved organic carbon content.
