RESULTS: The main research findings are as follows. (1) SBH is an integrated heritage with multi-scale and broad characteristics. It is not limited to architecture, but also includes many planning heritages, landscape heritages and facility heritages. Meanwhile, there is some variation in SBH across construction fields. SBHs in fields B and C were the most widespread (73.10% of the total), while those in fields A, F, and G were less frequently mentioned (all less than 1.00%). In addition, the share of SBH specific to the basic type was uneven. Overall, the most frequently occurring basic types were factories and facilities, collective organization buildings, government agencies, and assembly buildings (all greater than 10.00%), while medical and healthcare buildings, recreation buildings and facilities, municipal services buildings, and religious and memorial buildings were less common (all less than 0.10%). (2) The evolutionary characteristics of SBH were closely related to the development of society and contained six chronological stages and three patterns. Among them, in terms of stages, 1953 to 1960 was the fastest growing stage for both the number and size of SBHs, influenced by the first Five-Year Plan, the Great Leap Forward and the People’s Communalization Movement. The period from 1966 to 1975 was the trough stage, especially from 1966 to 1969, due to the emergence of the Great Proletarian Cultural Revolution. In terms of fields, field F showed an evolutionary characteristic of no significant growth → sudden increase, while fields A and H fluctuated. The remaining fields of SBH were all featured by significant growth → significant reduction → smooth transition, as they were mostly directly related to major political events. In addition, SBH has evolved with time, demonstrating progressiveness in its function, structure, and size.
结果:主要研究成果如下:(1) 社会主义建成遗产是一宗综合遗产,具有多尺度和广泛性的特点。它不仅限于建筑遗产,还包括许多规划遗产、景观遗产和设施遗产。同时,不同建设领域的社会主义建成遗产也存在一定差异。工业领域和农林业领域的遗产最为普遍(占总数的73.10%),而财贸领域、科技领域和大众文化领域的遗产则较少被提及(均小于1.00%)。此外,针对基本类型的 SBH 所占比例也不均衡。总体而言,出现频率最高的基本类型是工厂及设施、集体组织建筑、政府机构和会堂建筑(均大于10.00%),而医疗卫生建筑、娱乐建筑及设施、市政服务建筑和宗教及纪念建筑则较少出现(均小于0.10%)。(2) 社会主义建成遗产演变特征与社会发展密切相关,包含六个时间阶段和三种模式。其中,从阶段上看,受第一个五年计划、大跃进和人民公社化运动的影响,1953-1960年是社会主义建成遗产数量和规模增长最快的阶段。1966-1975 年为低谷阶段,尤其是 1966-1969年。从领域来看,科技领域的社会主义建成遗产呈现出无明显增长→突增的演变特征,而财贸和外交领域则为波动。其余领域的社会主义建成遗产因多与重大政治事件直接相关,基本呈现出大幅增长→大幅减少→平稳过渡的特点。此外,社会主义建成遗产也随着时间推移而不断发展,在功能、结构和规模上都表现出渐进性。
