共生理论下汉长安城遗址保护与发展策略探究

The Protection and Development Strategy of Chang’an City of Han Dynasty Site Based on Symbiosis Theory

随着城市扩张速度的加快,城市周边的大遗址生存空间逐渐被蚕食,大遗址的保护和发展已经成为一个棘手问题。本文以汉长安城遗址为例,借助“共生”理念的引入,探讨共生体系的形成途径,即在宏观层面形成遗址发展依托西安市的寄生模式,在中观层面形成遗址区和村落非对称均衡发展的偏利共生模式,在微观层面形成遗址点和周边环境的对称性互惠共生模式,同时加强各个层级之间的空间联动,营造多元化的共生环境,形成一个完整的、正向的共生体系,进而激发汉长安城遗址的发展活力。

With the rapid expansion of the city, the living space of the large sites around the city has been gradually eroded. The protection and development of the large sites has become a thorny problem. Taking Chang’an city of Han Dynasty as an example, this paper discusses the formation of symbiosis system by introducing the concept of “symbiosis”, that is, to form the parasitic mode of site development relying on Xi’an city at the macro level, to form the preferential symbiosis mode of asymmetric and balanced development of site area and villages at the meso level, and to form the symmetrical reciprocal symbiosis mode of site and surrounding environment at the micro level. At the same time, we should strengthen the spatial linkage between different levels and create a diversified symbiotic environment, so as to form a complete and positive symbiotic system and to stimulate the development vitality of the chang’an City of Han Dynasty.
