利用青藏高原贡嘎山、海北、五道梁、拉萨等4个野外台站2000～2002年的观测数据、陆地生态系统模型与2001年MODIS遥感数据相结合的方法来估算青藏高原区域的净初级生产力.结果表明:青藏高原区域的净初级生产力空间分布趋势表现出由东南向西北逐渐递减的梯度,该趋势也与水热梯度表现基本一致;整个青藏高原的净初级生产力为302.44×10~(12)gC yr~1,其中森林的净初级生产力最高,120.11×10~(12) gC yr~1,占整个高原净初级生产力的39.7%;全年中夏季(6～8月)的净初级生产力最高,246.7×10~(12)gC yr~1,约占全年总净初级生产力的80%.用实测数据验证模拟结果表明,二者非常相符. |

The Tibetan Plateau is the least human-disturbed region in the world. Its outstanding topographic features and ecological characteristics give it a fame of "Natural Lab" for global change research. An improved TEM model based on MODIS satellite data and field observations data during 2000-2002 were used to estimate annual net primary productivity (NPP) in the Tibetan Plateau. A validation by using the observed NPP at different sites shows that the estimated NPP is well agreed with the measured NPP. The simulated results show that the estimated annual primary productivity of the entire Tibetan Plateau is 302.44 * 10~(12) gC yr~1, among which forest NPP takes up 39.7% of the total, though forests comprise only 9.74% of the Tibetan Plateau region; NPP accumulation for summer is 246.7 * 10~(12) gC yr~1, which is 80% of the year total. |
