摘要
贵州喀斯特山区是我国水土流失以及石漠化较为严重的地区,水土流失面积高达40%以上,由于贵州特殊的地质、地貌、气候、植被、环境、以及人口压力过大,水土流失日益严重。水土流失以及土地石漠化已成为贵州省生态环境中最突出的问题。自1980年以来贵州广大科技工作者采取了各种不同的水土保持措施,使局部地区得到改善,但总体不容乐观。本文在总结前人大量工作的基础上,综合考虑水土流失特征及其影响因素、因地制宜,提出经济、有效、合理的适宜贵州喀斯特地区的防治措施。
Guizhou karst mountain region is serious soil and water loss and rocky desertification area in China. The larger soil and water loss acreage is over 40%. Because of special natural environment such as geology,geomorphy, limate and vegetation, and gross popalation, Guizhou＇ s soil and water loss becomes more and more serious. The soil erosion and rocky desertification have become the prominent problems. Since 1980, many Guizhou＇ s science and technology workers have strived various soil and water conservation measures, which has gotten to rather a partial improvement than a overall one. Summarizing a lot of predecessor＇ s works, and comprehensively considering the characteristics of soil and water loss and its influencing factors ,this paper properly proposed a economical, effective and resonable prevent and administer measure suitable to Guizhou＇s kast region.
