To measure the supply-demand level and the development capability of urban ecolsystem is the prerequisite in ensuring urban sustainable development. By using the analysis model of ecological footprint and the improved model of urban ecological carrying capacity, the utilization rate and supply degree of natural resources in Harbin City in 1998-2005 were quantitatively studied, with the supply-demand level and development capability of the City's ecosystem measured and analyzed comprehensively. The results showed that in 1998-2005, the demand of Harbin urban ecosystem was greater than its supply. Though the ecological deficit had an annual decrement of 2.45%, the contradiction between demand and supply of the ecosystem was still obvious. The diversity index of ecological footprint and the development capability both presented an overall uptrend, but the increment of the latter was far greater than that of the former, which illustrated the enhancement of the development capability being based on the consumption of ecological resources, and the urban development being of not sustainable. Social economic measures should be adopted to coordinate the contradiction between demand and supply and to realize the sustainable development of Harbin City.
衡量城市生态系统的供需水平和发展能力是确保城市可持续发展的前提。运用生态足迹分析模型和改进后的城市生态承载力模型，对哈尔滨市1998 - 2005年自然资源的利用率和供给程度进行了定量研究，全面测度和分析了该市生态系统的供需水平和发展能力。结果表明，1998 - 2005年，哈尔滨城市生态系统需求大于供给。虽然生态赤字以每年2.45%的幅度递减，但生态系统供需矛盾仍较为明显。生态足迹多样性指数和发展能力均呈总体上升趋势，但后者的增幅远大于前者，这说明发展能力的增强是以生态资源的消耗为基础的，城市发展具有不可持续性。应采取社会经济措施协调供需矛盾，实现哈尔滨市的可持续发展。
