偶然与必然--对子长县城空间形态拓展的思考

摘要

Due to the restriction of the topography and geomorphology in the gulied loess plateau, the urban space is expanded along the guly and valey land, which seems to have become a necessity. Based on the main problems of zonal spatial form and the future development demands and the analysis and selection to the large surounding area of the county which may afect the future development of Zi Chang County, the layout is finaly determined. Such a form can ease and avoid the limitation of the zonal shape in the resource consumption, social economy and environmental benefits, but also combine city with nature to the fulest extent. Although its formation seems come from a certain chance, it is the result of deep consideration of the county’s actual situation and its future development opportunities, it is a necessity of the fuly respect to the nature and the environment.%黄土高原沟壑地区城市由于受到地形地貌的制约，使得城市空间沿川道带状扩展，这似乎已经成为了一种必然。在分析当前子长县城带状空间形态的主要问题以及未来发展诉求的基础上，对可能影响到未来子长空间拓展的县城及其周边进行大面积、全覆盖的用地分析与选择，最终确定了环状布局形态。这样的形态能缓解和规避带状形态在资源消耗、社会经济、环境效益上的局限性，同时最大限度地使得城市与自然环境融为一体。它的形成虽然具有一定的偶然性，却是深入考虑子长县城现实状况和未来发展机遇的结果，是充分尊重自然、尊重环境的必然。
