【摘要】 <正> 海南岛气候区划,自50年代以来,已有过多次研究。高由禧把海南岛划分为5个气候区;何大章等把海南岛划分为8个气候区;广州地理研究所《广东气候区划》把海南岛划为16个区;丘宝剑、卢其尧把海南岛划为23个区;“中国农业气候区划”把海南岛划为4个基本区;其后1980—1981年间各部门对海南岛所作的各项应用气候区划很多,原则、指标、界线更是众说纷纭。我们认为,地区气候区划是探索气候地理规律性的,是所有气候区划(包括各种应用气候区划和综合气候区划)的基础。更多还原

【Abstract】 Hainan Island is a part of tropical China, The differentiation of temperature within Hainan Island is not significant, but that of rainfall distribution is quite remarkable. According to the principle of climatic division the main indices of climatic division in tropic should be given way from the heat (temperature) to the moisture (rainfall, rainy, season……). On the other hand, although the climate of Hainan Island is belong to tropical, but it is modified deeply by the monsoon, as the northen part of this island there appears a the Island, play an important role of climate division. Hence, moisture, temperature and topography of Hainan are chosen as the three main indices for the division work simultaneously. The climatic division of Hainan should be divided into eastern side and the western side by the parameter of water balance; also divided into nortern part and southern part by the thermal parameter (temperature), they made a cross shape over the Island; again, divide the mountain and the lower flat land(corespondant of wind condition) which made a circle shape. By mean of that, the regional division of Hainan may be after a model (fig. 1) divided into 8 division parts as follow: 1. NE part seashore plain climate, more cool, windy and more wet, such as in Wenchang. The shore lin forest belt should be built for agriculture. 2. NW part seashore plain climate, more cool, windy but more dry, such as Lingao. 3. NE part hill district and basin climate, more cold and wet in winter, such as Tunchang. 4. NW part mountain arid hill district and basin climate, occasionally fierce cold winter. It is harmful to rubber tree cultivation, such as in Baisha. 5. SE part seahore plain climate, more windy, more warm, and wet, such as Qionghai. Shore line forest belt should be built up for agricuture. 6. SW part seashore plain climate, more warm, fierce dry, such as Dongfang. 7. SE part of mountain and hill district, valley and basin climate; more wet and warm, such as Baoting. It is favour for rubber and other tropical crops, as, an old district of tropical agriculture. 8. SW part of mountain and hill district basin climate, more warm and dry, such as Ledong. There are many small areas with more favorable local climate for rubber here and there. It is a new region for the cultivation of rubber and other tropical crops or forest.更多还原
