摘　　要：植被净第一性生产力(NPP)是反映植被生态的重要因子,通过NPP对区域植被生态变化进行研究具有重要的意义.基于气候影响的自然植被的净第一性生产力模型,应用线性倾向值估计等统计方法,分析1981-2016年漳州市气候变化及NPP变化特征.结果表明,漳州市气候呈现气温显著升高、降水增多的暖湿化倾向,全市NPP年平均值随年际变化,并呈微略增加趋势,NPP年际总体波动幅度小,植被生产力较为稳定.漳州市NPP分布具有明显的县域差别,漳州南部县(东山、诏安)为NPP最小值区,而中部县(南靖、平和、云霄县)为最大值区,内陆山区县NPP值总体较沿海县市大.NNP空间分布呈现由东南部向西北部、南部向北部递增的分布态势,但各县市各年代NPP值都保持较为稳定,有利于漳州市良好生态的维持.漳州市降水与其NPP呈显著正相关,降水对NPP有着重要影响作用.Vegetation net primary productivity（NPP） is an important factor to reflect the vegetation ecology. It is significant to study the change of vegetation ecology through NPP. Based on model of the vegetation net primary productivity with climate, analyzed change characteristics of climate and NPP in Zhangzhou city in 1981-2016 by using statistical method of linear tendency estimation. The results show that temperature increases significantly and precipitation increases too. Climate becomes warm and moist in Zhangzhou city. The annual average of NPP is slightly increased with year,and the overall fluctuation of NPP is small and the vegetation productivity is stable. but distribution of NPP has obvious differences between county of Zhangzhou city. It is the minimum value area of NPP in southern Zhangzhou city（Dongshan and Zhaoan county）,while the maximum area is in central county（Nanjing, Ping He and Yunxiao county）, and the NPP value in the inland mountainous county is larger than that in the coastal county. Spatial distribution of NPP is increasing from the southeast to the northwest and south to the north, but NPP values of each county are stable in each age, which is beneficial to good ecology maintenance in Zhangzhou city. Precipitation has positive correlation with NPP significantly, and it plays an important role with NPP in Zhangzhou city.
