Abstract :
Community green spaces (CGSs) constitute a crucial element of urban land use, playing a pivotal role in maintaining the stability of urban ecosystems and enhancing the overall quality of the urban environment. Through the post-occupancy evaluation (POE) of green spaces, we can gain insights into residents' actual needs and usage habits, providing scientific evidence for the planning, design, and management of green spaces. This ensures that CGSs better meet residents' needs and improve their quality of life. The POE of CGSs relies heavily on high-precision data support. However, the current POE system for CGSs faces challenges, such as limited data collection methods, incomplete indicator systems, and excessive manual involvement. To address these limitations in data collection, this study proposes a comprehensive, dynamically monitored, objective, and sustainable POE system for CGSs. This system incorporates a multi-dimensional perception system that integrates the Internet of Things (IoT) and sensors to collect data from various sources. It establishes an evaluation framework from the perspectives of policy guidance and usage needs for CGSs, utilizing neural network systems and artificial intelligence techniques to compute the evaluation results. Using the Jiayuan Sanli Community in Beijing as a case study, this paper demonstrates the feasibility of the proposed system. A comparison between the POE results obtained using the multi-dimensional perception technique and those obtained manually reveals an 87% improvement in the accuracy of the evaluation results based on the multi-dimensional perception system. This system bridges the gap between planning perspectives and user experiences, contributing significantly to future urban land planning and land policy formulation.

Abstract :
This study aims to unravel the seasonal differences in outdoor thermal comfort (OTC) in a cold winter-hot summer region, as well as the comprehensive impact of meteorological and human factors, along with people's activity patterns in public spaces, on OTC. Questionnaire surveys, microclimate measurements, and photo recording were conducted over 21 daytime sessions in seven public spaces across winter and summer. The results indicated a significant seasonal OTC variance in Beijing. The neutral PET and neutral PET range were 21.9 degrees C and 15.2-28.6 degrees C for summer, and 14.3 degrees C and 6.1-22.5 degrees C for winter. Globe temperature primarily impacted OTC during both seasons, while wind speed was the only additional influential factor in winter. In Beijing, summer cooling is more crucial than winter insulation; however, winter wind protection is prioritized over summer ventilation. Some human factors, including age, activity level, visiting purpose, short-term thermal experience, and environmental stimuli, also influence OTC to some extent. Furthermore, this study identified significant variations in the temporal distribution and age demographics of attendees in various types of public spaces across different seasons, which considerably influence OTC. Our findings provide insights into the relationship between outdoor thermal comfort and public space use, which informs climate adaptive urban design.

Abstract :
在国家治理体系现代化改革的大背景下,开展国土空间规划城市体检评估,有助于及时揭示国土空间治理中存在的问题和短板,反馈规划实施效能。虽然,目前城市体检的实践较多,但是理论层面研究相对较少,导致评估科学性和系统性存在不足,亟需对城市体检原理的探索。因此,本研究引入循证治理理论构建城市体检框架,包括理论框架、内容循证和证据循证。在此基础上,通过对规划目标、规划实施和城市运行的指标循证,明确证据来源和证据等级,结合系统动力学描绘证据因果反馈路径,并以北京城市副中心体检为例进行方法论证,以期对城市体检理论发展提供新的思路。

Abstract :
Land-use patterns affected carbon emissions, which were influenced by urban land-use management in the long term. However, few studies linked carbon emissions with composite urban land-use management directly, leading to difficulties in reducing carbon emissions by urban land-use planning. Here, we proposed an integrated framework for carbon emissions accounting by land-use types and prediction through urban land-use manage-ment including the adjustment of urban growth mode and land-use structure. And the FLUS model and linear programming model were linked in the scenario analysis to predict carbon emissions. Finally, a decoupling model was used to evaluate the effects of urban land-use management on carbon emissions decoupling. A case study was conducted for Hangzhou from 1995 to 2015, showing the differences in carbon emissions in various scenarios for 2035. The results showed: (1) From 2010 to 2015, the carbon emissions of Hangzhou increased by 4.47 times, and it was dominated by the growth of carbon emissions for industrial land. (2) The potential of land-use structure optimization on carbon emissions reductions was from 23.80% to 28.04%, and that of compact urban growth was from 13.72% to 18.5%. (3) Decoupling relationships did not exist between carbon emissions and economic growth, and carbon emissions and urban land growth for all scenarios under urban land-use management in 2035. Our findings proposed an approach to consider practical ways to reduce carbon emis-sions through land-use management.

Abstract :
随着城镇化水平的提高、城镇化进程的发展,城市生态系统逐渐变得脆弱不堪,增强城市生态韧性水平对城市发展起关键性作用。以韧性的核心内涵为基础评估城市生态韧性水平,探究城市防范化解生态风险能力在空间上的差异,从而制定分区生态治理制度,是提升城市防范化解生态风险能力的有效办法。从抵抗力、适应力和恢复力三方面构建了城市生态韧性水平空间评估模型,以2020年北京市通州区行政边界、土地利用、重点排污单位、人口等数据为例,评估了2020年北京市通州区生态韧性空间格局,并利用空间自相关模型对其分区生态治理进行研究。最后利用地理加权回归分析模型(Geographical weighted regression, GWR)进行驱动力分析,探讨社会经济层面对城市生态韧性水平空间的影响,并提出建设性建议。主要得到以下结论:(1)在空间结构上,通州区生态韧性低值区域最多,占比为52.80%,主要分布于通州区北部、东北部、中部偏西及东南部;高值区域最少,占比0.83%,零星分布于偏西部地区和偏南部地区。通州区由于缺乏相对适宜的整体规划和统筹安排,使城市生态系统的循环体系受到了负面影响,从而导致东南地区抵抗力弱。同时,近年来降水点的南移使得大量水资源在城市热岛效应的作用下流失,通州区东南部及通州大运河沿线区域内恢复力呈现出大范围低值水平。(2)通州区中心偏西北地区为副中心的核心地带,呈现低韧性水平-高排污企业密度的集聚分布情况,且生态韧性低值区域主要集聚于新华街、中仓街、玉桥街等区域,说明这些区域的环境生态风险防范化解能力比较低,需要因地制宜地对生态危机做出可持续的分区生态治理,增强区域对生态风险的调节能力。(3)结合GWR模型的驱动力分析,城市生态韧性水平主要被城市功能多样性驱动,且城市功能多样性越强,城市生态韧性水平越低,在通州区西北部的城市副中心负向影响最为显著。研究结果为城市生态韧性水平发展优化提供了理论依据,为促进国土空间合理利用和有效保护发挥积极作用。

Abstract :
Commuting carbon emissions are an essential component of urban carbon emissions, and determining how to reduce them is an area of great debate among researchers. The current research lacks a tool and instrument that can extensively account for residents' commuting. Traditional methods are mainly based on questionnaire surveys, which have low accuracy at spatial and temporal aspects. High accuracy carbon emission accounting methods can effectively assist urban planning and achieve precise urban emissions reductions. This study applies a taxi commuting carbon emissions accounting method divided into two main steps. Firstly, the carbon emissions of taxi trajectories are calculated using taxi trajectory data and a carbon emission calculation method developed based on VSP. Secondly, the taxi trajectory and POI data are used to filter the commuter trajectory with the help of a two-step moving search method. In this way, the taxi commuting carbon emissions were obtained. Then, the spatial distribution characteristics of residential taxi commuting carbon emissions are analysed by spatial autocorrelation tools, which could facilitate low carbon zoning management. A typical working day in Hangzhou was selected as the research object of this study. The results show that (1) morning peak commuting carbon emissions in the main urban area of Hangzhou reached 2065.14 kg per hour, accounting for 13.73% of all taxi travel carbon emissions; and evening peak commuting carbon emissions reached 732.2 kg per hour, accounting for 4% of all taxi travel carbon emissions; (2) At the grid level, the spatial distribution of commuting carbon emissions in Hangzhou shows a single central peak that decays in all directions; and (3) The results at the resident community scale show that urban public transport facilities influence resident community commuting carbon emissions. In areas such as at the urban-rural border, resident community commuting carbon emissions show high levels of aggregation, and in the main urban area, resident community commuting carbon emissions show low levels of aggregation. This study not only provides a new method of commuting investigation but also offers constructive suggestions for future carbon emission reduction under Hangzhou's urban planning.
