基于CASA模型，通过使用GIS以及RS技术获得滁州市内植被、气候以及太阳辐射等地面空间数据，估算2001—2010年滁州市的植被净初级生产力，并分析其时空变化特征。根据研究区域生态系统的质量状况，掌握其时空分布规律。研究结果表明：从时间上来看，2001—2010年，滁州市植被净初级生产力呈增加趋势，其中：NPPMAX由2001年的646.546 gC／m2· a增加到2010年的752.478 gC／m2· a ，年均大致以近12 gC／m2· a的速度增加；从空间上来看，滁州市的植被NPP的空间分布格局产生较大变化，在过去10 a内，从同年与其他各区域相比较的结果来看，滁州市西北部植被净初级生产力逐渐减少，东南部逐渐增加，中南部则基本维持不变。

Based on CASA model ,the data of ground and space in Chuzhou City on the vegetation ,climate and solar radiation are gotten by using GIS and RS technology ,in order to estimate the vegetation net primary productivity (NPP) between 2001~2010 and analyzed the temporal and spatial variation based on the results .It is conducive to control the quality of regional ecosystem and the rule of spatial and temporal distribution .According to the result :from the aspect of time ,between 2001~2010 ,the NPP of Chuzhou shows an increasing trend .In 2001 ,the NPPMAX is 646.546 gC/m2 · a ,increasing to 752.478 gC/m2 · a in 2010 ,w hich gets to 12 gC/m2 · a every year approximately . From the aspect of space , the spatial distribution of Chuzhou vegetation NPP produces a significant change .For the past decade ,from the results of comparing with other regions ,the northwest of Chuzhou NPP has been decreasing .On the other hand ,southeastern is increasing gradually ,w hile the south of central is basically unchanged .
