摘要:
以气候变暖为主要特点的气候变化已成为当前研究的焦点,气候变化和不同类型的生态系统之间的相互作用更是受到广泛关注.东北地区作为我国气候变化的一个敏感区,观测记录和多种模式预估显示该区气候变暖显著并将进一步增强,降水变化趋势则不明显或略有增加.东北松嫩平原湖泊群是我国湖泊密度最大的湖区之一,但近几十年来,该区湖泊生态环境不断恶化,其中气候因素最为受人关注.本文从以下几个角度综述了松嫩平原湖泊群对气候变化的响应:(1)湖泊面积和湖泊水位;(2)湖泊水质;(3)湖泊生态多样性.在此基础上,探讨了该区未来气候变化对湖泊的可能影响以及湖泊的演变趋势,也阐述了在这种自然背景下的人类活动对湖泊环境演变的影响.

Abstract:
Climate warming as the main feature of climate change has become current research focus, and the interaction between climate change and different types of ecosystems is widely concerned. Northeast China is one of the most sensitive areas o£ climate change where the observation records and a variety of forecasting models show that it has experienced a significant climate warming period and the trend will be further enhanced. However, precipitations have not obvious trends or show alightly increase. Lake group in Songnen Plain is one of the highest density lake district in China. However, in the recent decades, its ecological environment has been continuously deteriorated due to several factors that climate change is the obvious one.In this paper, responses of Songnen Plain lakes to climate change are summarized from the following three characteristics:(1) lake area and lake water level; (2) lake water quality; and (3) lake ecological diversity. On the basis of above study, impact of future climate change on Songnen Plain lakes ami the lakes' evolution trend are estimated, Human activities' impact on the environmental evolution of the lakes is also discussed.
Key words:  Songnen Plain  lakes  climate change  human activities
