- Abstract:
- The objectives of the study were to explore the transformation law of plant species diversity and soil physical and chemical properties and their relationship in the karst rocky desertification ecosystem of Southwest China. The representative karst rocky desertification ecosystem, that is, Houchang at Qianxi County of Guizhou Province, was selected as experiment site. Based on the field investigation and laboratory analysis, the plant diversity, soil physical and chemical properties and their correlativity in the succession of karst rocky desertification were studied by the method of ANOVA, multiple comparisons, correlation analysis, and so on. Results show that the vegetation of karst rocky desertification ecosystem is very simple, the four indexes of plant diversity all are low, and the evenness and diversity indexes are significantly related with the succession of rocky desertification. There are significant differences of soil physical and chemical properties between different degrees of rocky desertification ecosystem, and with the increased degree of rocky desertification, most of soil physical and chemical factors decreased firstly and then increased. Soil physical and chemical properties are obviously related with plant diversity indexes. The change of soil physical and chemical properties can remarkably influence the characteristics of plant diversity in karst rocky desertification ecosystem. The results have important values for the protection of karst forest ecosystem and the control of rocky desertification.
