近40年来中国西北内陆5个典型湖泊面积变化遥感分析
Remote sensing analysis on lake area variations of 5 typical lakes in the Northwest of China over the past 40 years
摘要
Abstract
In the context of global warming, study on the change of inland lakes in Northwest China not only has great significance in inland water resources management and sustainable development strategy, but also provides reference for assessing the impact of climate change and human activities on lakes. This paper se-lects five inland lakes in Northwest China, using Landsat MSS/TM/ETM+/OLI data from 1970 to 2015, normalized difference water index ( Normalized Difference Water Index and NDWI) and modified normalized difference water index ( Modified Normalized Difference Water Index, MNDWI) to extract five typical lake boundaries and obtain the annual precipitation, evaporation and temperature from meteorological station data of 5 lakes were used to analyze reasons for the area change. The results showed that area of Hongjiannao in the past 30 years overall was reduced, and the groundwater impoundment and underground coal mining were the main causes for area reduction. Bosten Lake in recent 40 years area showed a decreasing trend after the first increase, whose area was mainly affected by the surface runoff and snowmelt. The area of Hulun Lake tended to decrease in the past 40 years, and its area change was mainly affected by the runoff into the lake. Baer lake is relatively stable in recent 30 years, and its area was mainly affected by the runoff;the area of Qinghai Lake in the past 40 years showed a trend of decreasing and then increasing, and the change of its area was mainly affected by the regional precipitation and the inflow of lake.关键词
