摘要
指出了近年来,许多学者提出中国西北特别是新疆地区气候由暖干向暖湿转型的观点。西北干旱、半干旱区湖泊及其流域的生态环境变化倍受关注,针对这些问题,选用2000~2013年7、8、9月份的Landsat TM/ETM+/OLI多期遥感影像,采用"综合分析法"对阿勒泰西部地区水域面积时序变化进行了动态分析,从自然因素和人类活动两个方面分析了引起该地区水域面积变化的主要因素。结果表明:阿勒泰西部的水域面积2000~2005年水域面积略微下降,2005年后逐年增长,这一变化与该区域的人类活动和气候变化的影响关系密切。
In recent years,many scholars have put forward the view that the climate in northwest China,especially in Xinjiang,is changing from warm and dry to warm and wet.The change of ecological environment of lakes and their basins in arid and semi-arid areas of northwest China has attracted much attention.In response to these problems,selecting Landsat TM/ETM+/OLI multi-phase remote sensing images from July,August and September of 2000-2013,this paper uses“Comprehensive Analysis Method”to dynamically analyze the temporal variations of wa-ter area in the western Altay,and analyzes the main factors that caused the change of water area in this area from two aspects of natural factors and human activities.The result shows that the water area of western Altay declined slightly from 2000to 2005,and increased year by year after 2005,which is closely related to human activities and cli-mate change in the region.
