水资源是区域经济社会发展重要的基础支撑物质系统。水资源的利用及其承载力研究是区域水资源规划和开发利用管理的重要依据。以黔南州为实例,分析了当地水资源变化趋势和用水结构变化,应用“承载人口数”定量研究黔南州地区不同福利生活水平下的水资源所能承载的人口数量与经济发展规模,并对几种方法进行了对比研究,结果发现水资源承载力不能就水资源单因子研究地区人口承载力,应根据地区资源因子找出承载力的控制因子。黔南州喀斯特人口承载力的决定性限制“原位性资源”是土地资源人口承载的极限,地区水资源丰沛,但水资源开发利用率低,已成为影响和制约喀斯特地区可持续发展主要制约因素,水资源可承载的人口数量有足够的空间,建议在考虑技术上的可行性、经济上的合理性以及生态环境的可承受性,通过工程措施提高黔南州水资源开发利用率,推动黔南州2020年全面建成小康社会。 |

Abstract: |
Water resource is an important regional supporting material system of the economic and social development.The carrying capacity of water resources is the important basis of regional water resources planning and management.Taking Qiannan Autonomous Prefectureas an example,this paper analyzed the change trend of local water resources and the structure of the per capita water consumption,calculated the water resources carrying capacity(WRCC)and economic development scale of the different living benefit levels by taking the “population carrying capacity” as synthetic index.The results showed that WRCC cannot be decided by the single water resources factor,but should be identified in accordance with the least local resources bearing capacity factor(the control factor)of different resources.The decisive limitations “in-situ resources” of the Qiannan Autonomous Prefecturewere the ultimate population carrying capacity of the land resources.The water resources of Qiannan Autonomous Prefecture were abundant but the development and utilization rate were low which restricted the sustainable development of the Karst area.Finally,with consideration of the rationality of technical feasibility,economic and environmental sustainability,it suggested to use engineering measures to improve the water resources utilization rate of QiannanAutonomous Prefecture,and promote the building a well-off society of Guizhou in 2020. |
