西部地区水资源基本状况 水资源总量 西部地区地表水资源每年为14563亿立方米,约占全国地表水资源总量(每年27100亿立方米)的54％;地下水资源为4613亿立方米,约占全国地下水资源总量(每年8700亿立方米)的53％。扣除地表水与地下水之间的相互转化量(重复计算量),西部地区水资源总量为15880亿立方米,约占全国水资源总量(每年28000亿立方米)的56.7％。
The basic situation of water resources in the western region The total amount of water resources Surface water resources in the western region each year for the 1456300000000 cubic meters, accounting for about 54% of the total surface water resources (271000000 cubic meters per year); groundwater resources 461300000000 cubic meters, about Accounting for 53% of the total groundwater resources in the country (870 billion cubic meters per year). After deducting the amount of interconversion between surface water and groundwater (calculated repeatedly), the total amount of water resources in the western region is 1.5880 trillion cubic meters, accounting for 56.7% of the total national water resources (2.8 trillion cubic meters a year).
