中文摘要	贵州碳酸岩盐出露面积达12万多km2,占全省国土总面积的73%,是我国喀斯特地貌最发育的省份;山多坡陡,人地矛盾尖锐,生态环境极为脆弱,水土流失和石漠化问题突出,是我国石漠化面积最大、危害最严重的省份.石漠化地区缺水少土,属于造林困难地带和生态治理的重点地区.文章以喀斯特石漠化发育典型的花江大峡谷右岸的贞丰县兴北镇顶坛片区为例,在阐述顶坛片区的自然环境条件及石漠化现状的基础上,详细分析了目前正在实施的几种石漠化生态治理模式,对这几种模式的效益进行了对比研究,指出了它们的优点与存在问题,并提出了相应的对策建议.
英文摘要	Karst landforms are wildly distributed in Guizhou province, China, and 73% of its total area is covered by carbonate rock ahe outeroppmg area of carbonate rock accounts to 12*10~4 km~2), and 92.7% of its total area beiongs to mountainous and hilly region. The area of sloping cultivated land accounts to 69.5% of the total cultivated land, where the eco-environment is very fragile Contradiction between human being and cultivated land is protruding, and soil erosion and rocky desertification is very serious Owing to he lack of surface water and soil in karst rocky desertification region, vegetation habitat is worsened. So it belongs to a kind of diffcult areas for afforestation and becomes one of key areas for ecological construction in China. This paper, taking Dingtan distract of Huajiang Gorge (in Baipanjiang river of Zhujiang river system) as an example, expounds the natural conditions and current status of the rocky desertification in Dingtan distract, and explores eco-controlling models of the desertification which are being put out effects such as "Chinese prickly ash + breeding pigs + marsh gas" (model one), "Alpina zerumbet (pers) Burtt + breeding pigs + marsh gas" (model two), "grain (for example: maize) crops and economic plants + Chinese prickly ash model or Alpina zerumbet (pers) Butt" (model three). Especially, after contrasting the effects of model one with model two and three, the author points out the advantages and disadvantages in the above-mentioned models, and finally puts forward some corresponding proposals to harness rocky desertification.
