摘要: 以贵州省为核心的中国西南岩溶区面临双重危机:生态恶劣,石漠化严重;人口贫困,全国1/3强的贫困县分布在该地区。石漠化综合治理需要从岩溶生态系统结构和运行规律出发,重点关注岩溶地下水的开发和可持续利用,水土保持和土壤改良,植被恢复和可适应性的经济植物选择,力求区域生态经济双赢、农民脱贫致富。

Abstract: Karst areas in Southwest China, with Guizhou as the focal center, are confronted with ecological deterioration and large areas of rocky desertification. Human activities are defined as the driving force behind the soil erosion. Further, local farmers in the area suffer from poverty due to a lack of drinking water, food and a weak living environment. Over one-third of national poverty-stricken counties occur in this part of China. To balance ecological protection and economic development in the region and help local farmers out of poverty we propose integrated controls and discuss on ground water exploration and sustainable use, soil conservation and remediation, and vegetation restoration (especially economic plant species) in this paper.
