摘　　要：治理岩溶山区石漠化,尽快恢复植被、实现生态系统的良性循环,水资源是生态建设所要考虑的主要问题之一。贵州普定后寨河流域是一典型的高原喀斯特流域。在分析了流域内喀斯特特征、水资源及开发利用现状的基础上,利用蓄满产流模型,对流域石漠化治理生态需水量作了预测,并对2010年在P=95%特枯年下石漠化治理后的水资源供需平衡作了分析,提出了流域水资源开发利用对策。The water resource is one of the important factors that should be taken into account in ecological construction for hammada harnessing, vegetation restoration, and realization of the benign circulation of the ecological system. Based on an analysis of the karst characteristics and current situation of water resources development and utilization in the Houzhaihe River Basin——a typical karst watershed, the ecological water demand of hammada harnessing in the river basin was predicted, and the coordination of water resources supply and demand after hammada harnessing was analyzed for 2010 under a probability of 95% for the low flow year. Finally, some countermeasures were put forward for water resources development and utilization in the river basin.
