不同气候适宜区的橡胶产胶潜力研究

基于2000—2015年MODIS NPP遥感数据,利用橡胶产胶潜力模型得到了中国橡胶主产区年橡胶产胶潜力;利用橡胶树种植气候适宜性区划的研究成果,得到了中国橡胶主产区橡胶气候适宜区分布;在此基础上分析了不同气候适宜区橡胶产胶潜力的差异及不同高程上橡胶产胶能力的差异。结果表明:(1)中国橡胶主产区中,云南橡胶产胶潜力最高,海南次之,广东最低;近十多年除云南橡胶产胶潜力呈微弱减少外,海南、广东两省均呈增加趋势;(2)高气候适宜区产胶潜力平均值为103.25g·m^-2;中气候适宜区橡胶潜力平均值为99.92g·m^-2;(3)在高、中气候适宜区,海拔在500~800m区域的橡胶年产胶潜力整体高于500m以下区域。

Research on the potential of rubber production in different climate suitable areas

Based on MODIS NPP remote sensing data from 2000 to 2015,the annual rubber production potential of China’s main rubber production areas was obtained by using the rubber production potential model.Using the research results of climatic suitability zoning for rubber tree planting,the distribution of rubber climatic suitable areas in the main rubber production areas in China was obtained.On this basis,the differences in rubber production potential in different climate suitable areas and the differences in rubber production capacity at different elevations were analyzed.The results showed that(1)among the main rubber producing areas in China,Yunnan had the highest potential for rubber production,followed by Hainan,and Guangdong was the lowest.In the past ten years,except for the slight decrease in rubber production potential of Yunnan rubber,Hainan and Guangdong both showed an increasing trend.(2)The average value of rubber production potential in high-level and medium-level climate suitable areas were 103.25g·m^-2and 99.92g·m^-2,respectively.(3)In the high-level and middle-level climate suitable areas,the rubber annual production potential of the area with the altitude of 500-800 m was higher than that of the area below 500 m.
