岩溶地区水资源承载力与经济社会的可持续发展

Water carrying capacity and economic society development in karst region

岩溶地区生态环境脆弱,水资源承载力相对较小.从水资源、环境、人口和发展几个方面,分析了水资源承载力具有时空性、动态性、适度性等特性.影响水资源承载力的因素主要有:水资源条件、岩溶生态环境因素、社会生产力水平、经济技术条件、社会消费水平与结构、其他资源影响及市场与政策法规制度等.可以从"开源"与治污,建设调蓄工程,强化节水措施,加强水权管理等4个方面提高岩溶地区水资源承载力.

In the karst region the ecosystem environment is bad while the carrying capacity of water resources is poor. According to the water resources, environment, population and recent development , a systematical research is made to analyze the characteristics of space-time, dynamic and adjustment for the water resources carrying capacity. The factors influencing water carrying capacity are as following: the conditions of water resources, karst ecosystem environment, social productivity, economy and technology ,social consumption ability and structure ,market policy and regulations. There are four ways to increase the carrying capacity of water resources in karst regions :tapping and waste treatment ,sluices engineering construction , water saving reinforcement and authority administration .
