在公共建筑屋顶引入生产性景观是对城市闲置空间积极的利用方式,具有生态、经济与社会等多元价值,有助于缓解我国土地城镇化快速推进所带来的诸多城市问题.本文以城市商业综合体屋顶生产性景观为例,基于ArcGIS平台,采用实地调研与问卷访谈等方法,结合全国总体特征与重点案例对其发展现状进行分析,结果表明:(1)受到自然和社会因素的影响,当前我国商业综合体屋顶生产性景观空间分布不均衡,84.21％位于东南沿海及四川地区;(2)该类型生产性景观运营发展态势良好,自2013年起每年建成数量持续增长,其中以结合自然教育和亲子游乐体验活动的商业模式发展最为稳定;(3)经营状况良好的案例在平面布局、交通功能、景观要素和空间设计上都呈现出较强的相似性;(4)问卷访谈显示市民对屋顶生产性景观有较高的参与意愿,而经营者在实践中仍然面临政策、资金、种植知识等方面的困难.基于此,本文对该类景观发展中存在的问题进行剖析并提出相应优化策略,以期为商业综合体屋顶的设计以及大量屋顶闲置空间的利用提供参考.“,”The introduction of productive gardens on public building roofs is an active way to use urban idle space. It has ecological, economic, and social values and helps alleviate many urban problems caused by the rapid ad-vancement of land urbanization. This paper takes the productive rooftop garden of an urban commercial complex as an example, and assesses its development status based on methods including ArcGIS, field research, and questionnaire interviews, combined with the overall aspects of the country and key case analysis. The results in-dicate several key aspects of the current status of such gardens in China. (1) As affected by natural and social factors, the current spatial distribution of productive rooftop gardens of commercial complexes in Chinese mainland is uneven, with 84.21％ located in the southeast coast and the Sichuan region. (2) The operation and development of this type of productive landscape is in good shape. The number of rooftop gardens has continued to increase since 2013, and the scale is generally greater. Currently, the business model which combines nature education and parent-child amusement experience activities is the most stable. (3) Cases in good operating condition tend to have relatively related characteristics in layouts, traffic functions, landscape elements, and space design. (4) Question-naire interviews show that citizens are highly willing to participate in rooftop productive landscapes, while operators still experience challenges in policies, funds, and planting knowledge in practice. This paper analyses the existing problems in the development status and strategy of the rooftop productive landscape. It proposes complementary optimization strategies to serve as a reference for the rooftop design of commercial complexes and the utilization of a significant amount of idle space on the roofs.
