基于EOS/MODIS NPP数据集，对神东矿区植被净初级生产力(NPP)变化的时空特征及主要影响因素进行分析。研究表明，2000—2010年，神东矿区植被年NPP主要介于(98~160) gC/( m2�a)区间，11 a平均值为139.80 gC/( m2�a)，低于同期全国植被年平均NPP值360.97 gC/( m2�a)约61.3％，低于同期矿区10 km缓冲区年平均NPP值142.49 gC/( m2�a)约2％，同时也低于同纬度对比区域年均NPP值161.97 gC/( m2�a)约13.7％。11 a NPP值一元线性回归分析表明，3个区域2000—2010年平均NPP变化趋势及斜率特征大致相符，相关系数均达到0.94以上；植被NPP与同期气候因子的相关性分析表明，神东矿区植被年NPP与年降水量相关系数较大，为0.716。%Based on EOS/MODIS NPP satellite remote sensing datasets the net primary productivity NPP chan￣ges in temporal characteristics and main influencing factors were analyzed in Shendong coalfield. The study showed that NPP mainly stayed between 98 and 160 gC/ m2 a range and the average value of 11 a is 139. 80 gC/m2 a from 2000 to 2010. It was lower approximately 61.3% than the average NPP of the national vegetation 360.97 gC/ m2 a and lower approximately 2% than the average annual NPP of mine 10 km buffer value of 142.49 gC/ m2 a in same period. In addition the study showed that NPP of coalfield was lower approximately 13.7% than the NPP of 161.97 gC/ m2 a in analogy area. By a linear regression analysis of NPP values to the above three regions during 11 a it showed that the variation characteristics of Shendong coalfield and its buffer and analogy area were basically identical. The correlation coefficients of NPP among three areas have reached more than 0.94 from 2000 to 2010. The correlation analysis of NPP with the same period of climatic factors indicated that Shendong coalfield vegetation NPP with annual precipitation was greater correlation coefficient of 0.716.
