岩溶山区土壤性质及其对土下溶蚀速率的影响
Effects of Soil Properties on the Dissolution Rate of Karst in Soils in Karst Mountain Area
摘要
Abstract
Taking the karst area of Zhongliang mountain as a case study, the authors discussed the impact of landuse and season cover on karst processes based on the data of field standard limestone tablet, moisture,porosity, pH, and organic matter content of soils. The results showed that there was appreciable difference in average dissolution rates of limestone tablets. They were from the highest to lowest as follows: wood land, grass land, vegetable land, tilled land. The dissolution rate of wood land was the highest one, which was much higher than the others. With compared the dissolution rate of rainy season and the whole year,it found that the dissolution rate of rainy season was higher than the whole year's, temperature and rainfall were the important fators in the dissolution process. The results indicated that the multi-variable coupling of the soil pH, organic and soil water affected the dissolution rate. Human activities could change soil properties or inhibit the process of karst. Wood land is conducive to the dissiolution of carbonate rocks,which can promote soil formation rate of dissiolution in karst region. Therefore,increasing vegetable cover in karst area is an effective measure to prevent desertification.关键词
