面向实施的老旧小区改造模式探索--基于低冲击开发理念的借鉴

In the era of stock planning,the renovation of old residential communities has become an important part of urban development in China.However,the renovation planning is difficult to implement.The paper points out three main factors that affect the implementation of old residential community renovation under the current system:complex property right structure,multiple stakeholders,and lack of funds.Based on the concept of Low Impact Development,and with minimizing the impact as the goal,the paper proposes a new mode for the renovation of old residential communities:through an analysis on property rights and interest game in old residential communities,and according to cost estimation,priority should be given to renovating the public elements that neither involve property rights or core interests nor require too many funds,including public space,roads,supporting facilities,etc.,with community management to be properly improved.In the end,with the renovation of Quanyechang Community of Wuhan City as an example,the paper concludes that this renovation mode can not only meet the urgent needs for renovation,but is also easy to implement.

城市住区公共服务设施与老年生活圈匹配规划研究

China entered an aging society in 1999 based on the United Nations’definition that an aging society is one where the population aged sixty and above accounts for more than 10 percent of the total population.Accordingly,community-based home care for older people has become a social trend and the main policy orientation of the urban elderly care service system.How to meet older people’s needs for living and caring services in urban residential areas is a major challenge for China to conduct urban redevelopment.This paper analyzes the supply-demand match of age-friendly public service facilities in communities based on the daily needs for public service facilities and the living circle characteristics of older people.Then it conducts an empirical study on typical residential communities in Suzhou and puts forward a hierarchical allocation strategy and improvement suggestions for age-friendly public service facilities in the self-sufficient community living circle,the near neighborhood living circle,and the urban expansion living circle.In addition,it proposes measures for improving the allocation of public service facilities in case communities in Suzhou through urban renewal.

Ocean energy applications for coastal communities with artificial intelligence–a state-of-the-art review

Ocean energy plays essential roles in reducing carbon emission and transforming towards carbon neutrality, with cleaner power production, whereas the vertical cascade ocean energy systems with spatiotemporal power supply characteristics might lead to fluctuated power frequency, disruptive disturbance and grid shock. Hybrid renewable energy dispatch, coordinated demand-side management, and electrical energy storages for grid ancillary services provision with different response time-durations are effective solutions to integrate ocean energy with stable and grid-friendly operation. This study is to review advanced ocean energy converters with thermodynamic, hydrodynamic, aerodynamic, and mechanical principles. Power supply characteristics from multi-diversified ocean energy resources are analysed, with intermittency, fluctuation, and spatiotemporal uneven distribution. Hybrid ocean energy storages with synergies are reviewed to overcome the intermittency and provide grid ancillary services, including pumped hydroelectric energy storage, ocean compressed air energy storage, and ocean hydrogen-based storage in different response time durations. Applications of diversified ocean energy systems for coastal residential communities are reviewed, with energy management and controls, collaboration on multi-carrier energy networks. Furthermore, application of artificial intelligence is reviewed for sustainable and smart ocean energy systems. Results indicated that, effective strategies for stable and gridfriendly operations mainly include complementary hybrid renewable system integrations, synergies on hybrid thermal/electrical storages, and collaboration on multi-carrier energy networks. Furthermore, depending on the geographical location, flexible on-shore and off-shore installation of transformers can provide large-scale ocean energy system integrations for long-distance transmission, with low transmission losses, low resistive losses, and simple system configuration. Research results can provide a heuristic overview on ocean energy integration in smart energy systems, providing alternatives for solar and wind energy resources and paving path for the carbonneutrality transition.
