| 摘 要： | 利用已建立的评价指标体系,对海河流域水资源安全现状进行评价。在海河流域的当地水资源量按372×108m3计算、引黄水量为60×108m3的条件下,海河流域的水资源保障是不安全的。但这种不安全属于气候干旱周期的不安全,如果气候转为类似1950～1970时期的湿润期,海河流域从水量来说就是安全的。海河流域的水资源不安全更突出的是水质不安全,所以加强水污染防治工作是提高海河流域水资源安全程度的首要选择。

| Abstract: | Using the water resources security appraisement indicator system constructed in paper "Regional water scarcity indicators and water resources security appraisement indicator system" (Jia Shaofeng et, 2002), authors appraise the situation of water resources security of Haihe Basin Water resources security means the normal need of human living, economic production and ecological sustaining to water resources can be satisfied by affordable cost The local total water resources of Haihe Basin is 372 billion cubic meter while 6 bcm can be divided from Yellow River, so the total water resource available for Haihe Basin is 432 bcm Besides about 11 bcm for ecological requirement, 8 bcm difficult to use (depleting in the form of ground water evaporation), there is about 24 bcm of consumerable water resources in Haihe Basin But human living and economic production has consumed about 30 bcm per year The gap between consumerable water resources and real depletion is offset by over withdrawal of ground water, engrossing of ecological water requirement, using seawater and reusing polluted water Because of the over exploitation of water resources in Haihe Basin, the water resources development in Haihe Basin is not sustainable and there exists strong water resources insecurity in Haihe Basin But the water resources insecurity of Haihe Basin is not permanent but has the quality of temporal scarcity in the period of less precipitation In 1980’s, averaged annual precipitation was 30% less than long term average In 1990’s it’s 4% less than long term average But in 1950’s, it’s 47% more than the average And in 1960’s, it’s 11% more than the average So, if a high water period comes, the water security situation in Haihe Basin will change much better Besides the water quantity problem, water quality problem is more serious to water resources security in Haihe Basin All pervading water pollution and sewage irrigation has caused threat to water and food safety. |
