摘要
岩溶区的水土流失具有特殊性,地上与地下流失并存,而且水土的地下漏失常被忽视。本文从自然因素和人为影响两个方面简述了石漠化产生的原因。在此基础上,重点分析了石漠化地区水土地下漏失的危害、水土地下漏失的作用机制,并通过综述土壤地下漏失研究方法,提出了石漠化地区水土地下漏失防治措施建议。研究旨为岩溶石漠化水、土地下侵蚀控制提供依据和参考。
Compared with non-karst area,the soil and water loss in karst area has its specificity,that is soil and water loss occurred at the same time in surface and underground leakage.Especially,the underground leakage is not well known by people.In this paper,we analyze the causes of rocky desertification from natural and human factors.Then,we give detailed analysis on the hazard and the active mechanism of the soil and water underground leakage in Karst rocky desertification.Finally,by summarizing the research methods of soil underground leakage,we propose the prevention and control measures of underground soil and water leakage in Karst rocky desertification.The purpose of this paper is to provide basis and reference for the control of underground soil and water leakage in Karst rocky desertification.
