中国的基本国情是所谓的“人口众多,地大物博”。人口学家估计,中国未来人口将稳定在15亿～17亿。所以,在讲国情时又多加了一句:“人均资源相对不足。” 中国的国情,还不限于“相对不足”,而且还有地区分布上的严重不均衡。 中国水资源的分布也存在着类似的情况。中国的地表和地下水资源量约为每年2.8万亿立方米,居世界第4位或第6位。但是,在空间和时间分布上“严重不均匀”。占国土面积 The basic national conditions in China are the so-called “large population and vast territory.” Demographers estimate that China’s population in the future will stabilize at 1.5 billion to 1.7 billion. Therefore, when talking about the national conditions, he added: “The per capita resources are relatively inadequate.” China’s national conditions are not limited to “relative deficiencies,” but there are also serious disparities in geographical distribution. A similar situation exists in the distribution of water resources in China. China’s surface and groundwater resources amount to about 2.8 trillion cubic meters a year, ranking No. 4 or No. 6 in the world. However, there is “serious unevenness” in the distribution of space and time. The total land area
