应用BIOME-BGC模型研究典型生态系统的潜热通量——半干旱地区吉林通榆的模拟

With BIOME-BGC Model on the Latent Heat Fluxes of the Typical Ecosystem: Simulations in Semi-arid Area at Tongyu,Jilin Province

年降雨量和年蒸发量在某种程度上反映了区域内水资源的丰富程度。随着社会和经济的发展，我国东北西部半干旱区的水资源供需矛盾日益突出。作者应用BIOME-BGC模型模拟了国际协调强化观测计划（CEOP）亚洲季风比较研究（CAMP）的一个地面观测基准站半干旱地区吉林通榆2002年10月-2003年9月草地和农田生态系统的潜热通量，并将模拟结果与通榆“干旱化和有序人类活动”长期观测站涡度相关法测定的观测值进行了比较，结果表明两者基本一致。此外，CEOP的观测数据对模型的验证和改进具有重要意义，半干旱区水资源的合理利用须引起当地政府和群众的重视。

The yearly rainfall and evaporation quantitively reflects the abundance of water resources in a region to a certain degree. Along with the development of the society and the economy in the western part of Northeast China, the conflicts between water resources supply and demand is increasingly obvious in the semi-arid area. This paper used the BIOME-BGC model to simulate latent heat fluxes of grassland and farmland ecosystem at Tongyu of Jinlin Province, and compare the simulations with the observations from the long-term station on aridification and the ordered human activity. This observation station is also one of the reference sites of Coordinate Enhanced Observation Period （CEOP） . The CEOP datasets is significant in validating and improving the model. The reasonable use of water resources in semi-arid area should be paid more attention to by the local government and people.
