The study investigated the response of surface water quality to urbanization in Xi'an, China. We qualitatively described the change in urban land use from 1996 to 2003, analyzed the status of the surface water environment, and constructed a model of urban expansion to simulate the water environment's response to urbanization. Our results revealed that patterns of land use changed dramatically, the rate of economic growth exceeded that of urbanization during the study period, and increasing urban land use was correlated with fluctuations in water quality. The simulated results suggested that urbanization had reached the environmental carrying capacity based on the average land utility and the marginal costs of pollution.
该研究调查了中国西安市地表水水质对城市化的响应。我们定性描述了1996年至2003年城市土地利用的变化，分析了地表水环境状况，并构建了城市扩张模型以模拟水环境对城市化的响应。我们的结果表明，土地利用模式发生了巨大变化，研究期间经济增长速度超过了城市化速度，城市土地利用增加与水质波动相关。模拟结果表明，基于平均土地利用效率和污染边际成本，城市化已达到环境承载能力。
