摘要
在对我国岩溶地区近年来水土流失研究现状、取得的成果及存在的问题进行综合性评价的基础上,展望了今后的研究趋势并提出了建议。结果表明:岩溶地区水土流失有其特殊的形成机理,其影响因素众多,流失过程更为复杂;水利部颁布的《土壤侵蚀分类分级标准》等规范、标准在岩溶地区有某种程度的不适宜性;目前对岩溶地区水土流失的研究缺乏系统性。引入地球系统科学等新的理论和方法,建立完善的水土流失监测研究平台,加强岩溶流域尺度上水土流失相关研究,是今后岩溶地区水土流失研究的主要方向。
The paper forecasts the future trend of study and puts forward suggestions based on the comprehensive evaluation of present status of study,achieved results and existing problems on soil and water loss of karst region in recent years in China.The outcomes show that: a) the soil and water loss of karst region has its own special mechanism of formation.It has numerous affecting factors and the process of loss is more complicated;b) the standards issued by the Ministry of Water Resources,such as Standards for Classification and Gradation of Soil Erosion has a certain inadaptability in karst region and;c) at present,the study on soil and water loss of karst region is unsystematic.Introducing new theories and methods of earth system science,establishing perfect platforms for monitoring and studying on soil and water loss and strengthening related research on soil and water loss of karst watershed scale are the main orientation for the study on soil and water loss of karst region in the future.
