前言 根据《北京市老龄事业发展报告(2019)》数据显示,北京的老年人口总体上呈现中心城区老龄化程度高,郊区相对较低的分布特征,尤其是东城区和西城区,65岁以上老龄人口比例达到17％,远高于全市平均水平,位于各区第一1.而广泛分布于北京老城的传统平房区由于形成年代较早、人口密集,老龄化问题尤其突出.2021年1月27日通过的《北京历史文化名城保护条例》中明确指出,要将"传统胡同"作为保护对象,推动成片传统平房区的保护和有机更新2.因此在目前以居家养老为基础的养老体系下,老年人群势必成为传统胡同空间的主要使用者,充分考虑老城老年居民的特征与需求,将会成为传统胡同保护与更新的重要环节.

传统村堡是中国北方长城沿线现存聚落的主要类型之一,集防卫性与居住性于一体.在其发展变迁历程中,由于受到战争局势、地理环境、日常生活、经济商贸等多方面因素的影响,在引发村堡功能属性转变的同时也导致村堡聚落空间形态发生嬗变.文章选取河北蔚县村堡中的特殊聚落类型——多堡聚落为研究标本,梳理了明清时期的村堡聚落形成背景,初步探析特定时期多堡村落与集镇空间的组群形态,并归纳出聚落空间形态的演变特征,最后在分析多堡聚落核心价值和保护现状的基础上,从4个层面提出具体的保护原则和发展策略,以期凸显出多堡聚落所蕴含的聚居图景与空间精神,为当代乡村振兴与传统村镇遗产保护提供借鉴和启示.

传统民居建筑在社会历史发展中具有不可替代的意义与价值,我国对于传统建筑的保护开始较早,但是对传统民居的保护起步较晚,从目前的保护成果来看,也不尽如人意.传统民居的保护手法有多种,民宿的出现为民居建筑的保护方法提供了新的可能,动态可持续性的民居保护可能会对民居价值的继承与传播产生更好的作用.文章试图从民宿改建方面分析民宿对北京民居保护的可行性及现实意义,并结合现状给出一定的保护策略及建议.

城市是一个生长的有机体.随着时间更替,城市中自然会出现新的建筑元素,北京四合院建筑也不例外.北京老城建筑更新中“新”与“旧”的关系一直受各界关注,新的元素如何存在于传统四合院中,并为其带来活力是当代建筑师面临的焦点问题.文章以建筑原真性为指导原则,从北京四合院更新中的新旧关系出发,诠释“差异并置”在四合院更新中的重要价值,并对四合院更新中差异并置的手法和原则进行解读.

文章论述地产结合美术馆的方式,将艺术植入于地产建筑之中,从经济利益出发,最大限度地覆盖项目,达到营销目的的同时更推进艺术创作.不同的营建方式,也有不同的经营模式和特点.从现阶段的发展而言,经济利益是地产美术馆的建设驱动力,文化生态是环境因素,地产的美术馆将最终目的是与文化艺术的高度融合,从而实现从生产到生活方式的根本性的转变.

随着社会文明的发展,时代的进步,图书馆作为城市重要的公共建筑正在发生着深刻的变革.传统的以保存、收藏书籍资料为核心的观念正在向以为人服务为宗旨的观念转变.在这一过程中作为载体的图书馆建筑也应顺应这一变化,以人的行为特征和模式为出发点,正确处理好人与知识载体、人与人、人与空间之间的互动关系,为人们知识的获取、思想的交流、公共生活的丰富提供便利和物质保障.

Shibaozhai historic tower, being boasted the sole dependent wooden structure of 400 years old, has being erected at the bank of the Yangtze River in Chongqing. The tower was built in way of special technique caled Chuandou structural system that was once prevalent in the region of southeastern China. Nowadays the Chuandou structure system is identified as a typical intangible heritage in China. The structural features and carpentry skils of the wooden tower are intensively described, folowing the analysis of the dependent structure how to subtly combine it with the clif and finaly realized the unique building is discussed in this paper. Finaly the protective measures and technical key points of restoration of the wooden tower are also stated.

Due to wind's unsteady and intermittent characteristic,the active power of wind turbine in the optimal wind-energy tracking control strategy fluctuates with the change of wind speed,which influences the power quality of wind turbine,causes fluctuation of grid frequency,and even causes stability problem to the grid.The control strategy of full power back-to-back pulse-width modulation AC-DC-AC converters of direct-driven permanent magnet synchronous generator is analysed.A flywheel energy storage system with the DC-side of converters with no change of converters' current control strategy is proposed.The energy control strategy to the flywheel energy storage system is designed to smooth the active power of wind turbine,in which the smooth power calculation method is presented.A simulation study is done on a 1.3 MW direct-driven permanent magnet synchronous generator based wind turbine.Simulation results show that the presented energy control strategy to the flywheel energy storage system can effectively smooth the active power of wind turbine to improve the power quality.
