一、海南岛热带季风气候有优势也有劣势 海南岛热带季风气候,是我国热带自然资源最具优势的地区。水热资源丰富,年太阳总辐射量为4800—6000MJ/m~2,年日照时数大部分地方都>2000h,年平均气温22.4—25.5℃,年降水量大部分地方>1700mm。在高温多雨的条件下,物质循环、能量交换迅速,成土作用快。森林资源丰富,热带珍贵树种与野生动植物种类繁多,植物约257科,4000种以上,其中热带树种(含引进树种)有200科、2000多种,本地热带树种有111科、1400多种,多于西双版纳与台湾。
First, Hainan Island has advantages and disadvantages of tropical monsoon climate Hainan Island tropical monsoon climate, is China’s tropical natural resources the most advantageous areas. The annual total solar radiation is 4800-6000MJ / m ~ 2, annual sunshine duration is more than 2000h, annual average temperature is 22.4-25.5 ℃, annual precipitation is mostly 1700mm. Under hot and rainy conditions, material circulation, rapid energy exchange, faster soil formation. The forest is rich in resources. There are a large number of tropical rare species and wild animals and plants. There are about 257 families and over 4,000 species of plants. Among them, there are 200 species and 2,000 species of tropical species (including introduced species), 111 families and 1,400 species of native tropical species In Xishuangbanna and Taiwan.
