墨西哥领土面积近200万平方公里,人口8500万,多年平均降雨量780毫米,年径流量47立方公里,可再生地下水55立方公里,年人均水量5000立方米,为世界平均值的两倍。然而,水资源地区分布却不均。占国土面积75％的大城市、工业区、灌区仅拥有三分之一的水资源,而另外25％的国土上水资源丰富,这一方面造成排水和洪水问题;另一方面又提供了可开发的水电资源。最近60年,墨西哥政府在开发水资源方面投资建设了一系列水利工程。其中包括:1270座水库,总库容为1.5亿立方米,约
With an area of nearly 2 million square kilometers and a population of 85 million, Mexico has an average annual rainfall of 780 millimeters, an annual runoff of 47 cubic kilometers and a renewable groundwater of 55 cubic kilometers. The annual per capita water volume is 5,000 cubic meters, twice the world average. However, the distribution of water resources is uneven. Large cities, industrial areas and irrigation districts, which make up 75% of the country’s land area, have only one-third of the water resources, while the other 25% have abundant water resources on the territory, which causes drainage and flood problems; on the other hand, Development of hydropower resources. In the recent 60 years, the Mexican government has invested in the construction of a series of water conservancy projects in the development of water resources. Including: 1270 reservoirs, with a total capacity of 150 million cubic meters, about
