摘要
目的水资源短缺问题已经成为锦州市经济发展的制约因素,针对锦州市的用水现状,从水资源、环境、经济以及社会等角度综合评价锦州市水资源承载力的大小,为锦州市经济可持续发展提供理论依据.方法基于锦州市水资源数据、社会经济数据、水文数据等,通过查阅文献、实地调研和数据整理,运用可持续发展理论,分析锦州市水资源现状,采用'虚拟水赤字评价方法'和'经济社会及生态环境评价方法'分别从广义和狭义水资源的角度对锦州市水资源承载力进行评价.结果锦州市2011—2015年水资源承载力从广义水资源角度看,除了2014年和2015年特枯水年时,水资源严重不足;2011—2013年水资源对经济、社会及生态的发展仍处于可支撑的范围;2011—2013年区域水资源对虚拟水的生产和消费均处于可支撑状态;2014年和2015年锦州市的水资源量不足以供给城市的生产生活、消费和经济发展的用水需求;由于水资源的不足,锦州市对地下水资源进行超采,导致地下水位逐年下降,造成了水量及水质的破坏.结论锦州市的水资源承载力已经严重不足,应当大力发展科技,找到合理利用绿水资源的科技手段,来提高水资源的利用效率,使锦州市的水资源承载力得到提升.
The shortage of water resources has become a constraint of the economic development of Jinzhou.Based on the current situation of Jinzhou,comprehensive evaluation of the water resources carrying capacity of Jinzhou from the perspectives of water resources,environment,economy and society provides a theoretical basis for the sustainable development of Jinzhou.Based on water resources data,social economic data and hydrological data of Jinzhou,the status of water resources in Jinzhou is analyzed by consulting literature,field researches and data compilations,applying sustainable development theory.From a broad and narrow perspective,we use the'virtual water deficit evaluation method'and'economic social and ecological environment assessment method'to evaluate the water resources carrying capacity of Jinzhou.The research results show the water resources carrying capacity of Jinzhou from 2011 to 2015.From the perspective of general water resources,water resources are seriously inadequate except for the 2014 and 2015 special dry years.From 2011 to 2013,water resources were still sufficient to support economic,social and ecological development;And regional water resources can support the production and consumption of virtual water from 2011 to 2013.In 2014 and 2015,the amount of water resources in Jinzhou failed to meet the water demand for production,consumption and economic development of the city;Due to the shortage of water resources,Jinzhou has overexploited groundwater resources that leads to the drop of groundwater level year by year and the destruction of water quality and quantity.The water resource carrying capacity of Jinzhou has been seriously insufficient.We should vigorously develop science and technology and use green water resource more efficiently and effectively to increase the water resources carrying capacity of Jinzhou.
