山地城市空间管制要素、准则及区划--以四川省万源市为例

The Factors, Rules and Zoning of Spatial Control in Mountain City——Case Study of Wanyuan City of Sichuan Province

以空间管制为政策手段,探索空间管制要素、准则及区划方法,对协调土地资源开发与保护之间的矛盾、保障山地城市建设与生态环境的互适平衡关系具有重要作用。研究以四川省万源市为例,从资源保护、环境保护、风险避让和市政设施防护等方面,将空间管制要素划分为4大类,16小类;从用地的生态特性、生态服务功能以及相关法律法规、规章规范的要求,制定各要素的空间管制准则;并应用景观生态学,选取类型水平和景观水平的景观指数,在分析万源市城市规划区景观格局现状及空间异质性变化规律的基础上,提取景观斑块,构建景观廊道,进行空间管制区划的研究。

Land resource is limited and ecological environment is sensitive in the most mountain city. As a public policy, space control is an efficient method for solving the contradiction between land resource development and protection and ensuring the harmony between city construction and ecological environment. Finding the factors, setting up the rules and exploring the zoning methods are the most important things during the research of the space control in mountain city. During setting up the master plan of Wanyuan city, a mountain city in Sichuan province, how to find the factors, how to set up the roles and how to divide the zone about spatial control are researched. Firstly, the space control factors are divided into fiiteen kinds based on the land resource protection, ecological environment protection, infrastructure protection and risk avoidance. Secondly, the spatial control roles are formulated based on the ecological characteristic, ecological function and relevant laws, regulations, rules and norms. Finally, the space zoning is divided by using landscape index, analyzing the landscape pattern and spatial heterogeneity variation, extracting the landscape patch, and constructing landscape corridor.
