福建省农业气候资源及生产潜力的分布特征分析

Analysis on Distribution Characteristics of the Agroclimatic Resources and Climatic Potential Productivity in Fujian Province

利用福建省15个气象站点1999～2008年气象资料,分析了福建省光、热、水等农业气候资源。运用孙惠南的模型计算了气候生产潜力,并从时间上和空间上分析它们的分布和变化特征。结果表明:福建省农业气候资源丰富,气候生产潜力较大,但是在分布上存在明显的地域性。从时间分布上看,农业气候生产潜力的年际变化受全球气候变暖的趋势影响不大,主要是受太平洋季风的年际波动影响。根据分析结果提出优化利用福建省农业气候资源的几点建议。

Using the data of meteorology in 15 meteorological stations in Fujian province from 1999 to 2008. The solar, temperature, water and other agroclimatic resources of Fujian were analyzed and the climatic potential productivity was calculated by using mathematic models of sun. The characteristics of distribution and changes of climatic potential productivity were analyzed from spatial and temporal. The results showed that the agroclimatic resources of Fujian are rich and the climatic potential productivity is huge, but regional distribution features are obvious. From the view of temporal distribution, the global warming trend had little effect on annual variation of agroclimatic potential productivity, which was mainly influenced by the annual fluctuation of pacific monsoon climate. At last, some measures of optimizing utilization of agroclimatic resources of Fujian were promoted.
