中国水资源

中国每年的平均降水

水资源总量降水形成的地表和地下产水量,即地表产水量与降水入渗补给地下水量之和。由两部分组成:第一部分为河川径流量,即地表水资源量;第二部分为降水入渗补给的地下水量,即地下水资源量中与地表水资源不重复的水量。

中国水资源总量约为2.81万亿立方米,地表水资源量为2.71万亿立方米,折合年径流深284mm;地下水资源量0.8288万亿立方米,不重复计算地下水资源量0.1009万亿立方米。

水资源总量分三部分:技术手段和经济因素等原因难以利用的;维持生态系统和地下水位等可持续发展因素预留的;可供人类经济社会发展利用的水资源可利用量,即在维持适宜的生态环境基础上,通过经济合理、技术可行的工程措施在当地一次性河道取水和地下抽水量,为8000亿立方米,约占水资源总量的30%。

Approach to static program analysis In computer science, abstract interpretation is a theory of sound approximation of the semantics of computer programs, based on monotonic functions over ordered sets, especially lattices. It can be viewed as a partial execution of a computer program which gains information about its semantics (e.g., control-flow, data-flow) without performing all the calculations. Its main concrete application is formal static analysis, the automatic extraction of information …
