摘要: 通过陆地生态系统碳循环模型(CASA模型),利用AVHRR的NDVI长期监测数据,逐像元模拟1981~2008年中国陆地生态系统NPP的时空变化,分析其对气候因子的响应关系。结果表明,中国陆地生态系统NPP总量在3.38 ~4.35 Pg C/a之间变化,平均约为3.8 Pg C/a,且研究期间呈上升趋势。在青藏高原、新疆天山地区和东北大小兴安岭、长白山等冷湿区,NPP年总累积量和年均温呈显著正相关,和年降水量呈显著负相关;地处华北的太行山、燕山等山区和内蒙古中部草原区等干燥环境区,NPP与年降水呈正相关关系;青藏高原及新疆地区和华北平原、四川盆地等农业区,NPP与年均温呈正相关关系。

Abstract: In this paper, using terrestrial ecosystem carbon cycle model (CASA model) to possess the AVHRR NDVI long-term monitoring data, we simulated the spatio-temporal changes of the NPP of terrestrial ecosystems by pixel in China from 1981 to 2008, and analyzed the relationship between NPP and climate factors. The results show that the total NPP of terrestrial ecosystems of China varied between 3.38-4.35 Pg C/a, averaging about 3.8 Pg C/a, and there is a upward trend in 1981-2008. In the cold and wet areas such as Qinghai-Tibet Plateau, Tianshan Mountains and the northeastern region of Da and Xiao Hinggan Mountains and Changbai Mountain, the total accumulation NPP and annual average temperature have a significant positive correlation ship, and significantly negatively correlated with the annual precipitation. In the dry conditions, such as Taihang Mountains and Yanshan Mountains, located in the north of China, and the central Inner Mongolia grassland regions, NPP and annual precipitation are positively correlated. In Qinghai-Tibet Plateau, Xinjiang and the agricultural regions such as North China Plain, Sichuan Basin, there has a positive correlation between NPP and average annual temperature.
