These include: Pinus forests, Quercus forests, Robinia pseudoacacia forests, Platycladus orientalis forests, mixed forests, economic forests, shrubs, bare rocks, uncultivated land, waters, and buildings. Based on the remote sensing images and the field-surveyed data, the structural changes during a 15 years period from 1986 to 2001 in various types of landscape within eight zones are analyzed using the 3S techniques and fractal methods. Four kinds of indexes, including the fractal dimension, diversity index, dominance, and fragmentation of landscape, are evaluated for each type of landscape. The results confirm that: (1) the fractal dimension is the characteristic parameter that generally provides the information about the landscape structure and its change. Its value is a comprehensive index reflecting the changes of spatial distributions, patch numbers, and patch areas. The higher the value, the more irregular the patch shape of landscape becomes, and so is the more complex the landscape structure. There are no significant differences on the fractal dimension values measured in 1986 and in 2001 among the landscape types except that Robinia pseudoacacia forests maintain a higher value. (2) The landscape structure is affected by many environmental factors. At the tourist sites it is mainly affected by the human activities; while at the high altitude sites it is controlled by the uniqueness of the vertical zonation. The variation tendency of fractal dimension values within each of eight different zones is similar in these two studying periods. (3) The landscape diversity and fragmentation index in 1986 were higher than those in 2001 from most sites, while the landscape dominance indexes were decreased slightly over this period. %K landscape structure %K fractal dimension %K GIS
