| 摘 要： | 地处热带的海南西部干旱问题突出，干旱已经成为当地发展农业生产的制约因素。从地理边缘视角，根据历史资料研究海南西部的干旱特征与成因，为海南西部干旱防治提供科学依据，可丰富区域干旱研究的内容与方法。研究发现，海南西部干旱具有以10年为周期的波状变化，干旱程度由沿海向内陆递减；海南西部是海陆交错带与山地平原交错带，山地、平原、海洋三大系统在干旱形成过程中发挥着不同的作用。

| Abstract: | Western Hainan is located in tropical zone, but its climate is very arid, and the drought has become a promi- nent problem in the development of local agriculture. Based on historical data of the drought, its characteristics, origin and forming mechanism have been studied in western Hainan from the perspective of geographic fringes. Drought is a 10-year cycle of undulant change, and the degree of drought reduces from coastal areas to inland. Western Hainan is the sea-content ecotone and mountain-plain ecotone, and the three systems of mountains, plains and ocean play different function in the formation of drought in western Hainan. The results provide a scientific basis for western Hainan to pre- vent and treat the drought. |
