摘要 了解不同季节陆地净初级生产力(NPP)的变化及与气候的相互关系以及其空间分布对深刻理解贵州陆地生态系统对全国气候变化的响应和陆地碳循环研究具有重要意义.本文使用1981—2000年间GLO—PEM模型模拟的贵州陆地NPP数据和同期气温、降水等数据,研究不同季节贵州陆地植被NPP的变化.结果表明,在1981—2000年期间,春季和秋季NPP都呈显著增加趋势,夏季和冬季NPP都呈减少趋势,春季是NPP增加速率最快的季节,夏季是NPP减少速率最快的季节.夏季NPP增加最高的区域分布于贵州南部的多数地区;夏季NPP降低最多的区域分布于贵州西北部. Study of the seasonal change in terrestrial net primary productivity (NPP) and its relationship with climate helps to understand the responses of Guizhou terrestrial ecosystem to global climate change and is important to carbon cycle research. In this study, time series dataset of Guizhou terrestrial NPP from Global Production Efficiency Model (GLO-PEM model) and corresponding information on climate were used to explore the seasonal trends of terrestrial NPP in Guizhou from 1981 to 2000. Seasonal NPP in Guizhou was found to show a significant increase in spring and autumn and a significant decline in summer and winter during the period of the 20 years studied. Spring NPP had the largest increase rate, while summer NPP had the largest decline rate. The largest increase in summer NPP occurred mostly in regions located in southern Guizhou, while the regions with the largest decrease in summer NPP were mainly located in northeastern Guizhou.
