摘　　要：红碱淖是国家重要的湿地自然保护区,对该地区水域面积变化的动态监测及其原因分析具有重要的意义。本文通过近33 a(1986-2018年)MSS、ETM、OIL卫星遥感影像数据和气象数据进行分析,结果表明:红碱淖所在区域年均温呈升高趋势,降水在波动中略增加。红碱淖水域面积呈先减小后缓慢增加趋势,1986年面积最大(58.61 km 2),2015年面积最小(29.96 km 2),缩减比例达49%。从2016年开始,水域面积持续稳定增加,持续锐减态势得到有效遏制。红碱淖水域面积变化与降水、气温等气象要素有一定关系,但最主要受人为干扰方面的影响,生态保护意识的提升对维护区域湿地生态安全具有显著作用。Hongjiannao is an important wetland nature reserve in China.It is of great significance to monitor the dynamic changes of water area in Hongjiannao and to analyze its causes.In this paper,based on analyzing MSS,ETM,OIL satellite remote sensing image data and meteorological data of Ejin Horo Banner from 1986 to 2018,the results show that the annual average temperature in Hongjiannao has tended to increase,and the precipitation has increased slightly in fluctuation.The water area of Hongjiannao has decreased first and then increased slowly.The largest area was 58.61 km 2 in 1986 and the smallest area was 29.96 km 2 in 2015,with a reduction of 49%.Since 2016,the water area has been steadily increasing,and the trend of continuous sharp decline has been effectively curbed.The change of water area of Hongjiannao is related to precipitation and temperature,but the most important is human activities,the raising of awareness for ecological protection plays an outstanding role in protecting ecological safety of wetland.
