漳州市净第一性生产力动态变化及敏感性分析
Dynamic Changes and Sensitivity Analysis for Zhangzhou City’s Net Primary Productivity
【摘要】 利用1961~2000年漳州市气象资料,运用Thornthwaite纪念模型估算漳州市净第一性生产力(NPP),并进行动态分析及对年均温和年降水量的敏感性分析。结果显示漳州市净第一性生产力随年份增加呈起伏递增趋势,且与年降水量和年均温正相关;漳州市净第一性生产力对年降水量变化比对年均温变化敏感,如果年降水量和年均温呈递增趋势,则对两者的敏感性将减弱,尤其对年降水量变化的敏感性下降显著。
【Abstract】 Thornthwaite memorial model was used to estimate the net primary productivity of Zhangzhou city according to the meteorological data of 1961~2000,and to carry out the dynamic analysis and sensitivity analysis of the annual rainfall and annual average temperature.The result showed that Zhangzhou’s net primary productivity revealed a trend of fluctuation increase year by year,and it had positive correlation with annual rainfall and annual average temperature;it was more sensitive to annual rainfall than to annual average temperature.If annual rainfall and annual average temperature presented a trend of steady increase,the sensitivity of the net primary productivity to both would be weakened significantly,especially to annual rainfall.
