- Abstract:
-
Vulnerability is an important indicator for regional ecology and environment assessment. Based on the VSD(vulnerability scoping diagram)framework, an indicator system of desertification vulnerability consisting of 17 natural and social economic factors was constructed to assess the evolutionary trend, identify important influencing factors, and propose strategies to control desertification in Inner Mongolia from 2000 to 2015. The results show that:(1)both exposure and sensitivity of desertification in Inner Mongolia showed significant spatial heterogeneity, the area experiencing the significant increase in desertification exposure mainly concentrated in the southwestern part, while the regions with obviously increasing trend of desertification sensitivity were mainly located in the central of Inner Mongolia; and the desertification adaptability of the whole region showed a stable increasing trend;(2)the desertification vulnerability of Inner Mongolia showed a spatial pattern of ‘lower-northeast and higher-southwest’; the regions with significant increasing trend of desertification vulnerability concentrated in the middle of the Urad Houqi and Bayan Nur, which were mainly induced by the increasing trend of exposure;(3)the adaptability improvement induced by economic development was the main reason for the reduction of desertification vulnerability in Inner Mongolia since 2000, and vegetation, wind erosion and dry-wet index were the key natural factors on the evolution of desertification vulnerability. The results of this research exhibited the great significance for desertification control and sustainable development of regional economy and society.
