Abstract: LUCC affects the safety and health level of ecosystem by changing land ecosystem structure and functions. Based on the data of land use change in the Ganzhou district during the period from 2001 to 2008, in this paper an ecological risk assessment of land use was developed, and a comprehensive evaluation on ecological benefit risk of LUCC and social effect was carried out based on Markov probability transition matrix. Moreover, a spatial quantitative analysis on the ecological risk of land use/cover change in 2008 was carried out so as to provide a reference to achieve a coordinated development between ecological environment and socialeconomic construction. The results are as follows: (1) The ecological risk of land use/cover change in the Ganzhou district occurred mainly in cultivated land and unused land, and its proportion was as high as 87.32% in 2008. (2) A complex conversion of land use types occurred during the study period. Ecological risk was extremely high in the ecotone. (3) Increase of land use degree index reflected the increasing extent and deepness of land use in the Ganzhou district. (4) Composite risk index of land use was increased to some extent during the period from 2001 to 2008, and the regional potential ecological risk will be affected by human activities to some extent.

Key words: LUCC, oasis city, land ecological risk, Ganzhou district
