Land Use/Cover Change and Its Landscape Ecological Risk Analysis in the Black Soil Region of Songnen High Plain——A Case Study of Bayan County
摘要
Abstract
Land use/cover change and its landscape ecological risk analysis are the basis for realizing regional land ecological and sustainable development.In this paper,Bayan County in Heilongjiang Province was taken as the study area,the spatial analysis function of GIS was used to make the layer algebra operation of the interpretation data of the remote sensing image in 1991,2006 and 2009,quantitatively analyze the land use change situation,the transition situation of every land use type in the 18 years,and the ecological risk index method was used to calculate and analyze the change situation of the landscape ecological risk in the three periods,and finally,the Kriging interpolation of the ecological risk index was performed to get the spatial distribution situation of its landscape ecological risk in Bayan County.The results showed that in the 18 years the land use change and the transition of every land use type were comparatively complex,and the main transition occurred among the cultivated land,forest land and other kind land;the change of land use structure led to the remarkable temporal-spacial differences of the landscape ecological risk index,and the change extent of the area proportion of every level ecological risk region;the interpolation result shows that the ecological risk increases year by year,and the ecological risk distribution was mainly affected by the terrain and land use type.The landscape ecological risk of Bayan County has the enlarging trend,ecological protection and construction of the area which is higher than the medium level should be strengthened so as to realize the coordination development of the ecological environment and society economy.关键词
