摘要:

利用光能利用效率模型(3-PGS)估算2003—2007年中国陆地植被NPP,并分析不同气候类型和植被类型的时空分布特征。结果表明: 2003—2007年中国陆地植被NPP年均总量为2.98 PgC, NPP年均值约为315.99 gC ·m-2 a-1; 中国陆地植被NPP的主要分布特点为沿水热梯度从东向西、从南向北递减,以海南中南部的热带林最高,而高原气候区最低; 全国植被NPP季节变化明显,不同气候区植被NPP均在7或8月达到峰值,12月或1月降至全年最低。

Abstract:

The paper aimed at investigating net primary productivity (NPP) of China terrestrial vegetation based on the light use efficiency model (3-PGS), and its temp-spatial pattern over various climate and vegetation types. The results showed that the annual mean NPP and annual sum of NPP in China terrestrial vegetation were approximately 315.99 gC ·m-2a-1 and 2.98 PgC, respectively during the period of 2003—2007. The distribution of NPP in China terrestrial vegetation was characterized as decreasing from southeast toward northwest China along the temperature and precipitation gradients. Tropical forests in the south-central of the Hainan island had the largest NPP value, whereas the plateau climate zone had the lowest values. NPP of China terrestrial vegetation also exhibited obvious seasonal changes with the peak values occurred in summer, and the lowest values in winter.
