| 摘 要： | 岩溶峰丛洼地水土流失以地下漏失为主,水土流失过程特殊、复杂,非岩溶区原有的各项水土保持工程及生物措施不适宜该区。以广西平果县果化示范区为例,在系统分析典型峰丛洼地不同地貌部位、不同环境类型条件下水土流失的主要特点和过程的基础上,通过试验与示范,研发了适宜于峰丛洼地不同地貌部位的水土保持生物技术和工程技术,取得了较好的生态、经济、社会效益,可为我国西南岩溶区水土流失及石漠化的综合防治提供科技支撑。

| Abstract: | The soil and water loss is dominated by underground leakage in karst peak-cluster depression area and the process is very specific and complicated.The engineering and biological measures that available in non-karst area are not suitable for karst area.In this paper we took Guohua pilot area of Pingguo County,Guangxi Province as an example,based on systematic analysis of the characteristics and processes of soil and water loss under different geomorphological positions and different environmental conditions in the typical karst peak-cluster depression,through test and demonstration,developed the biological and engineering techniques of soil and water conservation that are suitable for different geomorphological position of peak-cluster depression and achieved good ecological,social and economic benefits,providing scientific and technological support for the comprehensive control of soil and water loss and rocky desertification in the karst area of southwest China. |
