海南甘蔗种植的气候适宜性分析及区划

Climate Suitability and Regionalization of Sugar Cane Cultivation in Hainan

利用海南14个气象站点1971-2005年35a的实测资料,与甘蔗种植的主要气候指标及生长的主要气候条件进行对比,分析了海南各地的水热条件,并评价了该地区甘蔗种植的气候适宜性。结果表明,海南各地区气象因子中温度差异不大,影响甘蔗种植的气候条件主要是降雨量。全省除东方由于降雨量<1000mm不适宜种植外,其余各市县均可种植,其中白沙、琼中、屯昌、万宁、琼海、儋州五市县为最适宜种植区,其余为次适宜种植区。

By using 35 years data of 14 weather stations from 1971 to 2005 in Hainan and contrasting with main climatic index and climate condition for sugar cane cultivation and growth,hydrothermal condition of different region was analyzed in Hainan.Meanwhile,climate suitability was appraised.The results showed that the meteorological factors had little difference,and precipitation was the key factor for sugar cane cultivation.All regions were suitable to sugar cane planting except Dongfang city for precipitation<1000mm.Baisha,Qiongzhong,Dunchang,Wanning,Qionghai,Danzhou were the best regions,as the others were better regions.
