title: [Land degradation and landscape ecological construction in Liaoning Province].
abstract: The degradation degree, area and distribution of three types of degraded land caused by erosion, desertification and salinization were investigated in Liaoning Province by using landsat TM 1:250,000 and GIS Data. The area of eroded, desertificated and salinized land occupied 92.5%, 3.39% and 2.22% of the total provincial land area, respectively. Therefore, the land in this province was classified into three degradation regions: contemporary erosion degradation, geological erosion degradation, and desertification and salinization degradation region. The characteristics and the cause of degradation for each region were also analyzed. According to the local situation and the theory of landscape ecology, some landscape construction and restoration models were proposed.
