备注

西藏河谷地带在区域经济发展过程中,需要通过前瞻性地思考城市体系空间布局,处理好高原生物产业的生产发展与生态良好间的关系,为产业“带+区+园+基地”的发展奠定基础。拉萨市、林芝市、日喀则市和山南市等是西藏河谷的区域中心城市,在河谷城市体系中逐渐形成以“拉萨市+山南市”为“双核”、以“林芝市+日喀则市”为“两次”的城市空间布局构架,并在此基础上形成“东枣核+西枣核”的“双枣核”结构,为河谷产业布局奠定基础。“东枣核”和“西枣核”分别需要以加查县和拉孜县为节点构建城市团,成为河谷城市体系中的重要节点。金墨链、卧波链、尼墨链、仲土链等都是西藏河谷主城市链上的重要段落,将乡镇中心地与县级中心地连接一起,在城市链上扮演着重要角色。
In the process of regional economic development in Xizang river valley region,forward thinking should be given to the urban system spatial framework to tackle the relationship between the production development of plateau biological industry and the healthy ecological environment to lay the foundation for industry development in types of “belt, district, park,and base”. During the construction of the valley urban system,Lhasa, Nyingchi, Shigatse and Shannan, the regional central cities of Xizang river valley,gradually form the urban space layout framework with Lhasa and Shannan as the “dual-core” cities and Nyingchi and Shigatse as secondary-core cities. On this basis, the city structure of a “double jujube-core”pattern is shaped, including the “west jujube-core” and the “east jujube-core”, for the development of the Xizang valley industry layout.Gyaca county and Lhatse county should be taken as the vital points to construct city groups in the “east jujube-core” and the “westjujube-core” respectively. The city chain sections of Jinda town-Medog county,Wolong town-Bomê county,Nyomo county-Maizhokunggar county, and Zhongba county-Tubuga township, which are all dominant in Xizang river valley region, integrate town-level centers and county-level centers and play an important role in the city chain.
