摘 要：
基于CASA模型,利用我国自主研发的FY-3C气象卫星资料和同期地面气象观测数据,估算了2016年海南岛天然橡胶林的净初级生产力及其时空分布。2016年海南岛橡胶林NPP平均为556.32 g C/m~2/a,儋州、白沙、澄迈等市县是橡胶林NPP的高值区, NPP在600 g C/m~2/a以上。水热条件的改善会直接影响天然橡胶的NPP,其时间分布具有明显的季节性规律。4～9月海南岛气温适宜、降水充沛、太阳辐射充足,此段时间内的NPP约占生长季总NPP的82.05%,其中, 8月最大,达到95.75 g C/m~2/月, 10月之后开始明显下降。

摘 要：
The FY-3 C remote sensing data and meteorological data in 2016 were used to estimate the net primary productivity(NPP) and the spatial and temporal distribution of natural rubber plantations in Hainan based on CASA(Carnegie-Ames-Stanford Approach) model. The mean NPP of natural rubber plantations in Hainan in 2016 was estimated to be 556.32 g C/m~2/a. The NPP was more than 600 g C/m~2/a in the cities/counties like Danzhou, Baisha, Chengmai, etc. The improvements in moisture and heat conditions directly affected NPP, and the temporal distribution of natural rubber NPP was obviously seasonal. It was adequate in temperature, abundant in precipitation and sufficient in solar radiation during April to September in Hainan, and the NPP in this period accounted for 82.05% of the total NPP in the growing season. The maximum NPP was 95.75 g C/m~2 every month in August and the NPP began to decline significantly after October.
