| Beijing is located in the north-west of North China plain. Because of Beijing rapid development and population increase, the intensity of anthropogenic interference, roads, residential areas increased, the size of groups growing, and fast industrial growth, the original landscape constantly threatened and environmental quality also declining. In ERDAS,ARCINFO, software support, based on two sources of remote sensing images, using quantitative analysis and the application of quantitative methods of landscape pattern, we studied the pattern of the landscape impact factors and the status quo and Beijing landscape pattern analyses changes. Research shows 2001-2005 landscape pattern has undergone big changes. Between 2001 and 2005 , broken degrees increase, the overall increase in the number of sub-Victoria and the overall landscape of broken complicated. Beijing pattern of the past five years the landscape changes characterized by urban construction sites and the continuous expansion of rural construction sites, large occupation of farmland, construction sites and farmland area increased risk of higher. Beijing within six Central dramatic changes in the pattern of the landscape as the Beijing region, the period from two landscape pattern index shows that the human visual impact of a certain degree tend to increase and heterogeneity of the broken phase. Findings of the Beijing landscape pattern and changes in the urban landscape of the ecological environment is of great significance to the rational use of land and urban planning. |
