- Abstract:
-
The long-term stationary monitor was conducted to investigate the effects of different control measures on soil quality evolution in the karst rocky desertification areas. Three kinds of measures were selected: closed forest, artificial afforestation, and terracing, and the abandoned measure was taken as the control. The results showed that both of the measures and time had obvious effects on the soil physicochemical properties. The soil physicochemical properties and the soil quality fertility had been significantly improved by closed forest, artificial afforestation, and terracing. The effects of closed forest and artificial afforestation on soil quality were better than that of terracing. In addition, closed forest and artificial afforestation could significantly optimize the soil C/N. The soil C/P of these two measures was higher than that of terracing, and the soil C/P of closed forest and artificial afforestation increased with time, which reflected that closed forest and artificial afforestation suffered from the risk of soil phosphorus deficiency. Closed forest and artificial afforestation had better effect on improving soil quality. However, these two measures may lead to poor effect of vegetation restoration with the time due to the lack of soil phosphorus. Rocky desertification control is a long process, in which human intervention is needed to achieve sustainable development.
