英文摘要	Environmental vulnerability assessments are important for environmental management and ecological protection, especially in arid regions experiencing water-use conflicts and environmental problems. The Shiyang River Basin (SRB) has considerable ecological value for the survival and development of vast arid regions in western China. Taking the SRB, an important and typical arid inland region in China, as a case study, a framework was built to evaluate the environmental vulnerability of such regions. Twenty-three evaluation indices were selected to represent hydro-meteorological, socioeconomic, soil biological and topographical factors. A spatial principal component analysis (SPCA) was performed to determine the contribution of each index, and the environmental vulnerability distance index (EVDI) model was applied to synthesize four groups of factors. An environmental vulnerability map was classified into the risk categories none, very low, low, moderate, high and very high, which represent 6%, 5%, 8%, 16%, 26% and 38% of the total area, respectively. The results show the following: (1) The environmental vulnerability of the SRB is high, and its spatial distribution reflects interactions between human activities and natural environmental factors. (2) At the geographical unit scale, environmental vulnerability increases from south to north, which reflects obvious regularity in the vertical zonal distribution. (3) At the administrative district scale, the environmental vulnerabilities of Liangzhou and Jinchang Districts are higher than those of other cities and towns and the environmental vulnerabilities of urban areas are higher than those of rural regions. (4) Three ecological management zones are defined based on the environmental vulnerability, and they require different protective measures and management modes. The evaluation results may be helpful for arid inland regional planning, environmental restoration implementation and sustainable development improvements in the future. The assessment framework proposed and practiced can also be applied to other regions by adjusting the factors relevant to the variables of concern in the region of interest.
