| 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...

| 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 Qingha... |
