一、黄河水资源利用的现状我国水资源丰富,多年平均降水总量共约6万亿立米,相应地表径流约2.7万亿立米,占世界第三位。地下径流据粗略估计约0.7万亿立米。但其地区分布很不均匀,具有南丰北枯的特点。长江和珠江两流域的总面积约占全国的四分之一,而其地表径流总量却占全国的二分之一。黄、淮、海三流域的 First, the status of the Yellow River water resources China is rich in water resources, the average annual total rainfall of about 6 trillion cubic meters, corresponding to surface runoff of about 2.7 trillion cubic meters, accounting for the third in the world. According to a rough estimate of about 0.7 trillion cubic meters of underground runoff. But its distribution is very uneven, with the characteristics of Nanfeng North dry. The total area of ​​the Yangtze and Pearl River basins accounts for about a quarter of the country’s total, while the total surface runoff accounts for one-half of the country’s total. Huang, Huai and Hai three river basins
