福建农业气候资源时空分布特征及其对农业生产的影响

通过对近30~40a来福建省光温水资料的分析,阐述热量、水分、光照资源的时空分布特点及对农业生产的影响。结果表明,20世纪90年代以来福建的热量条件总体趋好,但仍常出现阶段性低温冻害过程;降水资源丰富,但存在降水年际变化大、年内分配不均的特点,常导致暴雨洪涝或干旱发生,使农业生产造成严重损失;日照南多北少,并集中在作物生长季内,能满足作物和果树的光合生长需要。

Characters of Temporal and Spatial Distribution of Agro-meteorological Climate Resources and Their Impacts on Agricultural Production in Fujian Province

Based on data of light, temperature and water in the last 30-40 years in Fujian Province, characters of temporal and spatial distribution of light, heat and water resources and their impacts on agricultural production were analyzed. Results showed that the quantity of heat became abundance generally since the 1990s but the low temperature damage and freeze often occurred. The precipitation resource was rich but the uneven inter-yearly distribution led to the occurrence of rainstorms and droughts and loss of agricultural production. The radiation concentrated in the growing period could meet the development requirement of crops and fruit trees.
