摘要
贵州喀斯特山区生态环境脆弱,特殊的地质、地貌、降水等自然因素与人为因素的交叉影响使贵州喀斯特山区成为水土流失严重、生态环境恶化、人民生活贫困的地区。本文探讨了喀斯特山区水土流失因素,提出了人为因素是贵州山区水土流失的主要因素,并提出了防治水土流失与土地退化的几项工程技术措施和政策措施,对解决贵州喀斯特山区的土壤匮乏,发展农业生产,改善生态环境有一定的意义。
The ecological environment of karst mountain area in Guizhou is fragile. The influences of the special natural factors （ geology, ground form , rainfall ） and human factors make＇Guizhou karst mountain area become the area of serious soil erosion, worse ecological environment and living poverty. This article probes into the soil erosion factor of the karst mountain area. It has been pointed out that the human factor is one of the main factors of soil erosion of Guizhou.
