    摘要:

    [目的]分析吉林省西部主要水体的动态变化,了解西部水资源现状,为水资源保护、利用和可持续发展提供有力支持。[方法]利用2000年以来的MODIS数据,采用目视解译的方法提取吉林省西部主要水体分布及面积数据,对年际、年内变化规律及影响因素进行分析。[结果]2000年以来,月亮泡水库、向海水库和查干湖均表现出向北部推进和水域面积增加的趋势;水体面积表现出明显的年周期变化规律,雨季期间及后期一般会出现较大的水域面积,形成了与季节性气候相适应的年周期变化状态;气候变化趋势,特别是降水对水体面积的影响较为显著,人类活动也起到了明显的推动作用。[结论]2000年以来,受气候变化及人类活动的影响,西部主要水体的水域面积有增加的趋势。

    Abstract:

    [Objective] To analyze the dynamic change of the major water bodies in Western Jilin Province in order to understand the current situations of water resource in the area, and to provide strong support for the protection, utilization and sustainable development of water resources.[Methods] We extracted the area and spatial distribution of major water bodies in Western Jilin Province by visual interpreting, based on MODIS images from 2000 to 2017. Moreover, the inter-annual and intra-annual variations of water area and the corresponding impact factors were analyzed.[Results] Since 2000, a northward tendency was showed in Yueliangpao reservoir, Xianghai reservoir and Chagan Lake, and the water area had increased. There was an obvious annual periodic change of the water area. Specifically, relatively larger water areas were found during the rainy season, which were compatible with the seasonal climate. The climate change, especially changes of precipitation had significant impacts on water area. In addition, human activities also played a significant role in promoting the growth of water area.[Conclusion] Affected by climate change and human activities, the water area of the major water bodies in Western Jilin Province has increased since 2000.
