Research on landscape pattern change and regional ecological restoration： A case study of Mentougou District, Beijing
In this paper, we chose two TM images of 1979 and 2005 as data source, based on normalized difference vegetation index and improved pixel binary model. After geome try revision, atmospheric correction and terrain revision with the aid of remote sensing technology, we calculated the vegetation coverage of Mentougou District, and dynamically monitored the vegetation cover changes of this district. The result shows that the vegeta tion coverage has a downward trend. Then we analyzed the temporal and spatial changes of the vegetation coverage based on the basic geographic information data and DEM data of this district, and studied the landscape ecology characteristics of the changes using （}IS technology and ecological landscape indicators by dividing the area into four parts as eco logical fragile areas, ecological control area, ecological coordination area and ecological stability area, and based on the characteristics for each division we proposed some sugges- tions for the ecological restoration, which can provide decision support for the local gov ernment to carry out some ecological restoration Projects.
