中文摘要	针对张信宝先生用~137Cs断代法计算黔西北麻窝山岩溶盆地土壤沉积速率，以及对谢良胜等研究成果提出的质疑，笔者从黔西北麻窝山岩溶盆地环境现状、环境演变、土壤堆积、~137Cs活度等方面进行论述。认为：易地堆积土壤来源的不确定性导致土壤层中~137Cs来源复杂，不能根据其峰值确定沉积年代，但可以作为定性判定土壤侵蚀强度的依据；在资料匮乏和无测站数据时，沉积量测量法是盆地型喀斯特山区土壤侵蚀计算的有效方法；麻窝山特殊的环境地质条件为喀斯特石漠化系统研究提供理想场所。
英文摘要	According to the average sediment accumulation rate calculated by Zhang Xinbao with ~137Cs dating method as well as doubt on the research results of Xie Liansheng etc. the basin environmental status, environmental evolution, soil sediment, ~137 Cs activity in the Mawoshan Karst Basin of the Northwest Guizhou were represented and discussed again. The results indicated that the uncertainty of source of soil accumulation resulted in complex ~137 Cs sources in soil layer. The peak value of ~137 Cs could not be used to determine the deposition time, but it may be used as a qualitative criterion of soil erosion intensity. Measuring sediment is an available method to calculate the basin soil erosion in Karst mountainous area when there is no station data and lack of detailed information. Mawoshan Karst Basin with special environmental geological conditions is an ideal location for the studies on Karst rocky desertification.
