摘 要: | 利用经改进的CASA模型,模拟分析了1999~2008年黄土高原地区植被净初级生产力(NPP)的变化趋势及其时空分布,并对其拟合可信度进行了分析。结果表明,在黄土高原地区水热条件较好的地区,实施退耕还林(草)工程对植被生长的变化及不同植被生态系统的生产力有着较明显的积极作用。

Abstract: | Based on improved CASA model,the change trend,spatial distribution and fitting reliability of NPP in the Loess Plateau were calculated form 1999 to 2008.The results showed that it had a positive effect of returning farmland to forest on change of vegetation growth and productivity of different vegetation ecosystem in good condition district of the Loess Plateau. |
