地球总水量的绝大部分储存于海洋中,淡水所占的比重很小,开发、利用、保护、管理好淡水资源,是世界各国共同关注的问题。本文介绍了地球水储量、陆地水资源、水资源开发、利用、保护现状及其展望,世界各国农业、工业、城市生活等各项用水状况及今后发展趋势。随着经济发展和人口增加,用水量日益增加,水的供需矛盾突出,必须提出解决供需矛盾的对策、采取相应措施,进行全面观划、节流开源、防治污染,强化管理。
Most of the Earth’s total water is stored in the oceans and the proportion of freshwater is very small. It is a common concern of all countries in the world to develop, utilize, protect and manage freshwater resources. This paper introduces the status of water reserves, land water resources, water resources development, utilization, protection status and prospects, the status of water use in agriculture, industry and urban life in the world and its future development trends. With the economic development and population increase, the water consumption is increasing day by day, and the contradiction between supply and demand of water is prominent. Countermeasures to solve the contradiction between supply and demand must be put forward and corresponding measures should be taken to conduct a comprehensive planning, cut expenditure, prevent and control pollution and strengthen management.
