环境保护--大遗址保护的可持续发展基点

当前大遗址保护的发展理念已趋向从传统的一维生态环境观上升到二维环境观（生态环境、社会文化环境）.从大环境观概念着手,可实现大遗址保护的可持续发展.在二维环境视角下,汉长安城大遗址形成了独特的文化景观,以此分析大遗址环境保护的方法,并从技术层面与社会管理层面上寻求大遗址保护的环境突破,最后得出结论：环境保护是大遗址保护可持续发展的基点;应以人为本,寻求保护措施的可操作性和有效性;要不断探索与完善文化遗产保护的有效方法和理论.

Environmental protection:basis of sustainable development of great site protection

The developmental idea of great site protection ascends from traditional one-dimensional ecological environment to the two-dimensional environments which include ecological environment and social cultural environment. On the basis of the conception of big environment, the sustainable development of great site protection can be realized. The particular cultural landscape of the site of the Han Chang'an City are come into being from the angle of two-dimension environments. Means of great site protection is analyzed and the breakthrough of great site protection is sought after from the technique field and social management field. At last, three conclusions are drawn: environmental protection is the basis of sustainable development of great site protection; being human-oriented, protection measures should seek maneuverability and validity; and continuously seek and perfect the effective methods and the theory of relic heritage protection.
