江苏省植物气候生产力时空演变特征
|
摘要
根据江苏省59站1960—2006年年平均气温、降水量资料,采用Thornthwaite Memo-riai模型计算了江苏植物气候生产力(TSPV),用EOF等统计方法分析了TSPV时空分布变化特征。结果表明:江苏省总体气候生产力水平呈南高北低的状态,随纬度增高而降低;北部气候生产力近年来不断增长,南部则较为平稳;EOF分析结果表明江苏的气候生产力主要有全省一致、苏南和苏北相反、江淮为中心等分布型。
EOF and other statistic methods have been used to study spatial-temporal distribution of climate-productivity with the data at 59 stations distributed in Jiangsu.The result showed that the average climate-productivity reduces with the increased latitude;in recent years,climate-productivity in north part of Jiangsu province was growing while in the south it was steady.The EOF analysis indicated the climate-productivity distribution in Jiangsu province can be divided into several categories.
