摘　　要：县城是我国重要的城乡人居形态,县城绿色低碳建设是实施我国双碳战略的重要领域。受山区自然地理环境和人地关系影响,山地县城建设面临建设用地局促和生态环境脆弱的双重约束,高度形态管控是处理好就地城镇化空间容量和山水生态安全格局之间矛盾的关键技术支撑。传统高度形态管控路径偏向引导经济“增量”空间集聚,缺乏对地方山水格局传承和绿色低碳发展需求的技术回应。研究以浙南山区永嘉县上塘中心城区为例,通过梳理绿色低碳建设与山地县城高度形态管控的空间逻辑,提出以山水融入为基础建立空间秩序框架,以主客互馈为原则满足空间价值需求,以山城眺望为支撑建构空间管控途径。借助山城视觉互馈的技术方法,提出山水融入目标下的高度形态管控指标体系,构建“主客互馈”的整体管控数字模型并建立“空间高度+控制强度”双维管控机制。最后,在山地县城总体城市设计中,从整体空间结构重塑、视廊景观层次丰富、城市魅力界面优化三方面实现高度形态的绿色低碳管控及其空间技术传导。The green and low-carbon construction of counties,an important urban-rural habitat pattern,is an important area for implementing the double carbon strategy.Affected by the natural geographical environment and man-land relationship,mountainous counties are faced with the dual constraints of limited construction land and a fragile ecological environment.As a consequence,height form control is the key technical support for handling the contradiction between the spatial capacity of in-situ urbanization and the ecological safety pattern of mountains and rivers.Traditional height form control tends to prioritize the spatial clustering of economic growth,lacking the technical response to the inheritance of local landscape and the demand for green and low-carbon development.This paper conducts a case study on Shangtang central urban area in Yongjia County located in the mountainous area of southern Zhejiang Province.It develops a spatial order framework in which mountains and rivers are integrated based on summarizing the spatial logic between green and low-carbon construction and the height form control of mountainous counties,to meet the demand for spatial value enhancement by following the principle of subject-object mutual feedback and to develop space control approaches with the support of mountainous city overlook.Taking the mountainous city visual feedback as technical means,it puts forward a height form control indicator system guided by the goal of landscape integration,develops a digital model of overall height form control featuring subject-object mutual feedback,and establishes a two-dimensional control mechanism of“space height”and“control intensity”.In terms of the overall urban design of mountainous counties,the green and low-carbon control and spatial technique conduction can be achieved through reshaping the overall spatial structure,enriching the visual landscape hierarchy and optimizing the urban charm interface.
