Research on Mountainous Landscape Pattern Gradient Changes in Beijing Donglingshan Area

Abstract

Abstract: The mountainous landscape structures display the landscape functions and ecological processes. The changes of landscape structures are always an important content of mountain landscape research.In this paper,Beijing Donglingshan area was taken as the strdy site.Study plots were set in the area. By virtue of GIS,landscape dynamic list was made for the years of 1984,1994 and 2002.Results showed:1)during the recent 18 years,landscape structures represented a trend of fragmentation;2)The effects of human activities on landscape types were different.Agricultural cultivation and logging made forest and grassland become farmland and shrubs;3)Villages and farmlands were made up of small patches and possessed higher complex edges.Shrubs,forests and grasslands were composed of big patches and possessed lower complex edges.

Key words: landscape pattern, gradient change, mountains
