一、从我国淡水资源短缺看加快发展海水淡化制造产业的重要性近年来我国淡水资源总量为2.75万亿立方米左右,水资源总量位居世界第6位,但人均淡水资源量只有2125立方米,仅为世界人均占有量的四分之一,被联合国列为13个贫水国之一。目前,有16个省、区、市人均水资源量低于1700立方米,为中度缺水。同时,淡水资源时空分布极不均
First, from the shortage of fresh water resources to see the importance of accelerating the development of desalination manufacturing industry In recent years, the total amount of freshwater resources in China is 2.75 trillion cubic meters, the total amount of water resources ranked sixth in the world, but the per capita fresh water resources only 2125 Cubic meter, accounting for only one-quarter of the world’s per capita, ranked by the United Nations as one of 13 water-poor countries. At present, the water resources per capita in 16 provinces, districts and municipalities is less than 1,700 cubic meters, which is moderately water-scarce. At the same time, the spatial and temporal distribution of freshwater resources is extremely uneven
