摘 要 ：在环境污染与城市化发展变化特征分析的基础上，利用计量经济学的方法，对1984～2004年咸阳市生态环境与城市化耦合特征进行了实证分析。结果显示，咸阳市工业三废排放量与城市化水平呈现倒“U”型曲线。工业废水排放与城市化的耦合曲线正处于倒“U”的右侧，而工业固体废物和工业废气与城市化的耦合曲线则处于倒“U”型左侧。目前咸阳市城市化水平还比较低，仍处于初级阶段。城市化进程的加快带来了人口的聚集和经济的快速发展，从而使三废的排放不断增加。在今后城市发展中，政府应加大环境保护力度,制定严格的环境保护政策，促使以煤炭为主的能源结构向清洁能源转变，以高能耗、高排放、高污染的经济结构向低能耗、低排放、低污染转变，以及以第二产业为主的产业结构向污染较少的第三产业转变，达到工业三废排放量逐渐下降，生态环境逐步改善，生态环境和城市化协调发展。

Abstract:This paper analyzed changes in environmental pollution and urbanization development to study the coupling effects of urbanization and eco-environment in Xianyang City for 1984～2004 by using economic method. The general relationship between industrial waste discharge and urbanization follows an inverted U-shaped curve. While the curve skews rightwards for industrial wastewater discharge, it skews leftwards for industrial exhaust gas, and solid waste. At present, the urbanization in Xianyang City is in the elementary stage. But when the urbanization takes off, discharge of the industrial waste will rise with increase in population and economic development. Therefore, along with urbanization, the local government should expand environmental protection and strengthen environment protection policies in order to promote energy structure transformation from coal to cleaner sources of energy; transform the economic structure from high energy consumption, emission and pollution to low energy consumption, emission and pollution; restructure industrialization from primary industry to tertiary industry with low pollution. Such policy shifts can gradually decrease the waste discharge, improve the ecological environment and harmonize the development of urbanization and the ecological environment. 
