- Abstract:
-
In order to grasp the change trend of ecosystem and habitat quality in Datong Beichuan Heyuan River Source Area National Nature Reserve and optimize the protection countermeasures and measures, the changes of land use and vegetation coverage in the National Nature Reserve of Datong Beichuan River source area were analyzed based on the three time nodes of 2005, 2010 and 2015. Based on the habitat assessment module of invest model, the habitat quality of the reserve was assessed, and the vegetation coverage(VFC)was used to modify the habitat suitability(H)index, so as to get more accurate results of habitat quality assessment. The results showed that shrubbery, grassland and bare land were the main land uses in the reserve area; from 2005 to 2015, the change of land use was not significant, a small part of bare land was converted to grassland, the overall habitat quality of the reserve area was significantly improved, especially the shrubbery in the north and south, which was basically consistent with the distribution pattern of vegetation coverage in the reserve area.
