摘 要:贵州岩溶地貌发育,山多地少,水土流失严重,生态环境恶化,农业生产条件差、水平低,发展可持续农业既是贵州特殊农业生态环境的客观要求,也是兴黔富农和实现农业现代化的必由之路,然而贵州岩溶山区脆弱的生态环境束缚着该区农业的可持续发展。对贵州岩溶山区生态环境脆弱性成因进行了分析,归纳为:地形的复杂性、地质环境的特殊性、降水的不均匀性和人为因素4个方面。从土地农业生产、水资源利用和自然灾害3个方面阐述了该区脆弱的生态环境对农业可持续发展的约束作用,最后提出了相应的对策。Guizhou province is located in the southwest of China where the karst landforms are widely distributed but its eco-enviroment is fragile. Most Guizhou area is occupied by mountains and hills where the soil ersion is very serious,and the natural conditions of agriculture produce is adverse,therefore the level and efficiency of agrictthure produce is also very low. The only way of agriculture development in Guizhou Karst mountain region is to carry out sustainable development strategy. Whereas fragile eco-enviroment is restricting the agricultural sustainable development in the region. The paper analysed The cause of the fragility in Guizhou Karst mountain region was analyzed and the effect of fragile eco-enviromental restriction on the region was as follows: land using, water resource and nature disaster, etc. Finally, the corresponding countermeasures were suggested.
