Abstract: In order to evaluate the landscape stability in mountainous area of southwest China, this paper analyzed the landscape stability in middle and upper reaches of the Wujiang River from three aspects of landscape matrix stability, landscape patch stability and landscape density stability based on the Landsat remote-sensing images in 2000 and 2015. The results showed that the landscape stability decreased during the period from 2000 to 2015. Landscape patch stability showed the characteristics of bare land>shrubbery>grass>water>forest>plantation>built-up land. Landscape density stability showed the characteristics of bare land>shrubbery>grass>forest>water>built-up land>plantation. There were significant spatial heterogeneities for landscape matrix stability, landscape patch stability and landscape density stability in each watershed. Ecological projects and rapid economic development are dominant factors affecting landscape stability in middle and upper reaches of the Wujiang River.

Key words: landscape pattern, stability, GIS, Wujiang River,China
