Abstract

Abstract: This paper applied principal component analysis, combined with landscape pattern indicators affecting the ability to maintain the stability of landscape pattern, analyzed characteristic of landscape pattern from the landscape structure, features and heterogeneity, constructed evaluation model of the stability of landscape pattern, and evaluated the stability in the studied area by using land use data of Lanzhou city collected in 2000 and 2010. The results showed that landscape pattern had significant changes in Lanzhou city in recent 10 years. The conversion between the main landscape types was frequent and showed the feature of obvious unidirectional conversion. The stability of landscape pattern reduced gradually in the study area. However, the stability of landscape pattern had differences between every county, its' ranking followed Honggu District, Xigu District, Anning District, Yuzhong County, Yongdeng County, Gaolan County, Qilihe District and Chengguan District. The landscape types of the high stability are waters and grassland and the lowest is construction land. It should enhance the land potential, improve land use degree, plan construction land reasonably, and protect waters and grassland with ecological services.
