Dynamic Change Remote Sensing Monitoring and Driving Forces Analysis of Hulun Lake Wetland
Author : Zhiguo Pang, Yanan Wu, Jingxuan Lu and Wei Qu
Based on the multi-source remote sensing(RS) data of Landsat MSS\TM\ETM+ and HJ-1A, in this paper the dynamic variation of the Hulun Lake wetland area from 1975 to 2011 was revealed, and the driving forces was analyzed by using the normal differential water index (NDWI) model and supervised classification method. The results show that the Hulun Lake has presented a trend of shrinking and degradation in the past 36 years, which the water body area decreased by 22.7% and the figure of wetland area declined by 25.9%in 2011 compared with that of 1975. It is believed that natural factors are the main causes that led to the reduction of water body and wetland area in Hulun Lake, and socio-economic factors accelerate the degradationof the Hulun Lake wetland to some extent.
