地处祖国最南端的海南省,是我国第二大岛,区域包括海南岛和西、南、中沙群岛的岛礁及其海域,总面积3.4万平方公里。全岛有大小河流154条,从中部山区或丘陵区向四周分流入海,构成河流短小,水流湍急,呈放射状的海岛水系。海岛雨量充沛,水资源总量达319亿立方米,为国民经济的发展提供了有利的条件。然而,由于这里属热带季风气候,素有“台风走廊”之称,降雨量集中在夏秋季,冬春多旱象,又受地形和河流特征的制约,只有充分建库拦蓄,水资源才能得到
Located in the southernmost tip of the motherland, Hainan Province is the second largest island in China. The region includes the islands and reefs of Hainan Island, West, South and Zhongsha Islands and its sea area with a total area of 34,000 square kilometers. There are 154 large and small rivers throughout the island, which are diverted into the sea from the central mountainous or hilly areas and form a short-span, fast-flowing, radial island water system. With abundant rainfall, the island has a total of 31.9 billion cubic meters of water resources, which provides favorable conditions for the development of the national economy. However, since this is a tropical monsoon climate, known as the “typhoon corridor,” said the rainfall concentrated in summer and autumn, winter and spring more drought, but also by the terrain and river characteristics of constraints, and only fully reservoir storage, water resources can be obtained
