摘要： 台湾省位于我国东南部海中,由台湾本岛和附近数十个岛屿组成.陆地面积约36000平方公里.北回归线在本岛中部偏南处通过.近70%的面积为山地和丘陵,四列近乎平行的高峻山脉,南北纵贯全岛,超过3000米的山峰,多达60余座,最高的玉山主峰,高达3950米.本省冬季盛行东北季风,夏季盛行西南季风.太平洋北赤道暖流的一支沿台湾岛东海岸北上,并分流一股进入台湾海峡.在这样的地理位置、地形、季风和洋流等因素的共同作用下,形成台湾省干湿状况时空变化十分明显的特征.

Abstract: To evaluate the moisture conditions of Taiwan Province,four indices are used:aridity index Eo/r,precipitation excess r-Eo,evaporation ratio E/Eo and evaporation difference Eo-E,where Eo is the potential evaporation,r the precipitation and E the actual evaporation.The monthly and annual values of the potential and actural evaporation of 22 stations in Taiwan are calculated by using revised Penman and Turc formulae,respectively.Based on the analysis of the spatial and temporal distribution of the four indices,seven moisture regions in Taiwan are delimitated:The Northeast Perhumid Zone(A1),The East-Middle Perhumid Zone(A2),The Mountainous Perhumid Zone(A3),The West Humid Zone(B1),The Southwest Humid Zone(B2),The Southeast Humid Zone(B3) and The Penghu Semiarid Zone(C).
