【摘要】 利用集对分析法诊断识别出2005-2017年贵阳市水资源承载力的演变特征和脆弱性指标。研究结果表明:水资源承载力评价等级均高于2.0,处于临界超载状态;实施节水型社会建设后水资源承载状态呈现向好态势;人均水资源量和供水量不足以及农业灌溉定额偏高是水资源承载力致弱的主要因子;夯实节水型社会建设、提升水资源利用效率和加强地下水战略储备资源的保护与利用是提升贵阳市水资源承载力的一个有效途径。更多还原

【Abstract】 The set pair analysis(SPA) is used to diagnose and identify the evolution characteristics and vulnerability of water resources carrying capacity of Guiyang City from 2005 to 2017. The results show that all level evaluation of water resources carrying capacity is higher than 2.0. After the construction and implementation of the water-saving society, and the water resources carrying capacity has shown an improved trend. Both inadequate water supply and high quotas of agricultural irrigation are responsible for the weakening of water resources carrying capacity. A series of effective ways, including the better construction of a water-saving society, improving the efficiency of water resources utilization and strengthening protection and utilization of groundwater strategic reserve resources are to better the water resources carrying capacity of Guiyang City.更多还原
