摘要

陆地生态系统对气候变化的反应已成为土地管理者和政策制定者关注的核心问题。极端气候和趋势对半干旱山区生态系统的生产力有很大的控制作用。伊尔加兹山脉位于土耳其从大陆型气候到相对温和的黑海型气候的过渡地带，其丰富的生物多样性为评估典型的半干旱山区生态系统对气候变化的脆弱性提供了独特的机会。因此，我们评估了中分辨率成像光谱仪（MODIS）预测的2000年至2010年间受地形和气候影响的伊尔加兹山脉年净初级生产力（NPP）的时空变化。年MODIS NPP范围为500至912克·米-2·y-1。海拔、坡向和植被类型与MODIS NPP显著相关。MODIS NPR对干旱高度敏感，在研究期间，研究像素的平均MODIS NPP普遍下降。MODIS的响应

NET PRIMARY PRODUCTIVITY OF A MOUNTAIN FOREST ECOSYSTEM AS AFFECTED BY CLIMATE AND TOPOGRAPHY

Response of terrestrial ecosystems to changing climate has become an issue of central importance for land managers and policymakers. Climate extremes and trends have a strong control on productivity of semi-arid mountain ecosystems. Located in a transition zone from continental type climate to relatively mild Black Sea type climate in Turkey, the Ilgaz Mountains with their rich biodiversity, provide a unique opportunity to evaluate vulnerability of a typical semi-arid mountain ecosystem to climate change. Therefore, we evaluated spatio-temporal variation of annual net primary productivity (NPP) of Ilgaz Mountains predicted by Moderate Resolution Imaging Spectroradiometer (MODIS), as affected by topography and climate between 2000 and 2010. The annual MODIS NPP ranged from 500 to 912 g .m -2 .y -1 . Elevation, slope aspect, and vegetation type were significantly correlated with MODIS NPP The MODIS NPP was highly sensitive to droughts, and the mean MODIS NPP generally decreased across the study pixels in the study period. The response of MODIS
