湿地的消长与区域气候变化密切相关,沼泽湿地的气候调节功能不仅能削减沼泽气温和湿度的波动幅度,而且也能减缓相邻区域气温和湿度的变幅。而沼泽的疏干会导致地方气候的温、湿变幅增大,灾害性天气增多。研究沼泽动态与灾难性天气之间的关系,有利于认识资源与环境的相互影响作用。采用遥感技术分析了阿尔泰山西北部分布的沼泽湿地24年来的动态变化,将它与该地区24年来的灾害性天气发生情况做了比较分析,对两者内在联系进行了定性分析。结果表明阿尔泰山西北部的沼泽动态变化与灾害性天气现象之间在某种程度上确实存在着内在联系。这个结果一方面证明了沼泽湿地缓解气候生态功能的重要性,另一方面表明了沼泽的变化在某种程度上可能会导致灾害性天气。
The growth and decline of wetlands are closely related to the regional climate change. The climate regulation of marsh wetlands can not only reduce the swings of marsh air temperature and humidity, but also reduce the amplitude of temperature and humidity in adjacent areas. The swamp dewatering will lead to the local climate of temperature and humidity increases, disastrous weather increased. Studying the relationship between swamp dynamics and catastrophic weather is good for understanding the interaction between resources and environment. Using remote sensing technology, the dynamic changes of the distribution of marsh wetlands in the northwestern Altai Mountains over the past 24 years were analyzed and compared with the occurrence of disastrous weather over the past 24 years in the area. Qualitative analysis was made on the intrinsic relations between the two. The results show that there is indeed some intrinsic link between swamp dynamics and disastrous weather phenomena in the northwestern Altai Mountains. On the one hand, this result proves the importance of swamp wetlands in mitigating climate and ecological functions and on the other hand indicates that swamp changes may to some extent lead to disastrous weather.
