海南岛水资源开发利用展望

海南岛是我国第二大岛、自然条件优越，资源丰富，经济发展潜力大。但由于海南岛孤悬海上，与大陆无任何水源联系，岛上的所有生物和社会经济发展所需的水只能靠当地降水。虽然降水资源丰沛，但时空分配很不均匀，干湿季分明，长达半年的旱季降水很少，再加上目前缺水必要的水利工程进行调蓄，大部分地表径流白白流入大海，可利用水资源不多，致使当前城市生活和农业用水较为紧张。为改变这种局面和满足未来需水要求，从现在开始，必须加快进行水利建设，拦蓄水量为全社会提供更多的水资源。展望未来，水资源开发前景是十分诱人的。单从水源条件的保证性分析，2010年以后工业产值可翻一番，城市人口可增至700万人。

PROSPECT ON WATER RESOURCES EXPLOITATION,AND UTILIZATION IN HAINAN ISLAND

ainan is the second largest island in China which has great potential in agricultural development thanks to its advantageous natural conditions and rich resources. But however,. currently, all the water required for domestic use and socio-economic development in Hainan has to, depend upon precipitation because of isolation of the iD1and on the sea and its disconnection with the continent in water sources. Of the plentiful precipitation, the available water resources are inadequate for the uneven temporal-spatial. distribution of sufficient precipitation brings little rainfall in 'the .half. year-long dry sea6on which is clearly distinct from wet season. In addition, the lack of necessary water conservancy projects to regulate and store surplus watrer in wet season results in the discharge of most surface runoff into sea for nothing. As a consequence, the demands of available water for both domestic purpose in urban area and agricultural production fall short of supply. In order to change the present situation and satisfy future water requirements, efforts should be doubled to quicken the speed of water conservancy construction for the sake of providing more water resources to the society by means of improving water storage capacity.
