摘    要:以往土地利用变化对气候的影响多是从地表参数的改变角度去研究,而气候变化的一个重要方面是温室气体的增加。通过收集整理三江平原生长季(510月)不同土地利用类型的温室气体排放通量,根据温室气体的增热潜能,比较得出,在三江平原林地、小叶章、毛果、漂筏、稻田和大豆几种土地类型中,对区域气候影响的大小依次顺序为:大豆>小叶章>毛果>林地>稻田>漂筏。由此表明,三江平原稻田对于区域的气候的变化贡献比旱地小。在过去几十年中,由于土地利用变化而导致温室气体排放的总变暖潜力增加,为三江平原气候变暖提供了佐证。

关 键 词:三江平原  土地利用  温室气体  区域气候

Abstract:Global-warming is one of the important environmental problems.Previous studies often interpreted the influence of land-use change to climate by studying the change of the earth surface's parameters.But the increase of greenhouse-gases,an important factor which influence the climate is neglected.By analyzing the data of fluxes of greenhouse-gases from various land-use types in Sanjiang plain,we compare the influence of different landuse to climate.The result expresses that the greenhouse effect of woodland>Calamagrostis angustifolia>Carex lasiocarpa>Carex pseudo-curaica>paddyfield>soybean are different.The magnitude of the influence can be soybean>Calamagrostis angustifolia>Carex lasiocarpa>woodland>paddyfield>Carex pseudo-curaica.So,if the wetlands will be changed into farm land,the rice paddy is more suitable than dry land.In the past years,for the land-use change in Sanjiang plain,total quantity of different greenhouse-gases has changed.Among them,the amount of CH_4 decreased,but that of CO_2,N_2O increased.The increase of GWP which is resulted by land-use change is one of important factors of region climate warming.
Keywords:Sanjiang plain  land-use  greenhouse-gas  regional climate
