In order to accurately measure the sustainability of western China, "West Ecological Footprint Model" was set up. Calorie value per kilo of bio-products was introduced to solve the problem that different bio-products cannot be directly added in weight. The key parameters for the model were computed based on the actual data collected from western China. Finally, as an experiment, the model was employed in calculation of Ningxia ecological footprint as well as in sustainability assessment of Ningxia economic development. The results indicated that per capita ecological deficit of Ningxia was up to 0.749 hm2, and that ecologically surplus population took up 33% of the total in 2009; so, current Ningxia model for economic development is unsustainable. Proposals were put forward to better the situation, too. "West Ecological Footprint Model is suitable for studying ecological footprint among provinces in western China and it also provides a reference for ecological footprint analysis in other middle to small areas in China.%为了更准确评估和比较西部各地区发展的可持续性,“西部”生态足迹模型引入热值概念,克服了不同属性的生物产品不能直接加总的难题.计算“西部”生态足迹模型的核心参数,并尝试性的将该模型用于宁夏生态足迹核算.结果显示,2009年宁夏人均生态赤字达0.749 whm2,生态剩余人口占总人口的33％.认为,宁夏的发展已经不可持续,同时提出了改善性建议.“西部”生态足迹模型适用于西部地区间生态足迹分析,其思路也可为其它中小区域的生态足迹研究提供参考.
