Abstract

The desertification reversion process vulnerability refers to the sensitivity of desertification reversion phenomenon on social-ecosystems' various disturbances, and the tendencies and possibilities of reversion trend decline or reverse development due to lack of the capacity to respond to adverse disturbances. It has great significance for system governance and comprehensive regulation of desertification, and reversion trend sustainability from the perspective of social-ecological systems to comprehensively analyze the contribution mechanism of desertification reversion process vulnerability. Yanchi County, a typical area of desertification reversion in agro-pastoral ecotone, is taken as the study region in our study. Based on the DPSIR model, we constructed the vulnerability evaluation model and applied the fitting curve to explore the vulnerability contribution mechanism. The results showed that:(1) The curve of desertification reversion process vulnerability slowly rose during 2003-2005. In 2006 this index rapidly rose and reached the maximum value (0.733) in 2007 then declined to 0.442 from 2008 to 2011. After 2012, this index showed a slight rise and then fell. (2) Social factors, especially the human activity is the important influence factors of the desertification reversion vulnerability. The population urbanization, ecological management index, the number of electromechanical well, planting trees and grass area each year, teacher/student ratio and net income per capita of rural households have a great contribution to vulnerability of desertification reversion process. Their curve fitting R² are all higher than 0.5. (3) Population urbanization, ecological management index, year afforestation area and water consumption per ten thousands Yuan GDP were the significant factors to slow down the vulnerability, while increase of the population proportion of non-agricultural livelihoods will increase the vulnerability. (4) With the electromechanical wells, rural household income and county economy development, the vulnerability of desertification reversion process rose first and fell later, while with the increase of teacher/student ratio and per unit land area of fixed assets investment, the vulnerability fell first and rose later.
