摘要
目的揭示古代西安地下水污染过程和原因及其污染物质的长期积累对城市发展的影响。方法在野外实地考察和查阅文献记载、考古实证的基础上,结合现代环境地学理论和方法进行研究。结果西安地下水污染始于汉代,唐代以来最为突出,污染物质长期积累,使得污染日益加剧;城市发展对地下水的开采及生活污水、垃圾、人畜排泄物等不合理排放是造成地下水污染的主要人为原因;西安所处的特殊地形条件和地下水水文条件是造成地下水污染物质长期积累的客观原因;地下水污染引起的水资源短缺成为其后城址迁移的重要原因之一,现代西安城市地下水污染是历史上污染物不断富集和积累的结果。结论在当前西安城市水资源开发利用和环境治理规划中,必须充分考虑西安特殊的地形和地下水水文条件及污染物质在地下土壤沉积物和地下水中长期积累的问题。
Aim To explore the process of the underground water pollution and its reason, and its impact on urban development in ancient Xi＇ an. Methods Using field research, desk research and theories of modern geography. Results The underground water were polluted from the Hart dynasty and deteriorated afterward. The pollution caused damage not only to the special terrain and water environments in ancient Xi＇an and also to the unreasonably utilization of water resources. Conclusion The shortage of underground water resources because of pollution resulted in the urban development. The pollution of underground water in present gears was mainly caused by the accumulation of contaminations in historical periods. So we must consider the special terrain and water conditions in solving modern water utilization.
