Balanced Consideration of Urban Park Green Space to Provide Services and Disservices

Ecosystem services(ES),the benefits of ecosystem function and structure to human well⁃being,have been receiving continued attention from international community since the publication of the millennium ecosystem assessment(MA).While humans enjoy all kinds of services provided by the ecosystem,they are also adversely affected by the services provided by the ecosystem,which are called ecosystem disservices(EDS).Based on EDS related research,this paper expounds the EDS concept and connotation to urban park green space as the research object,defines the concept and classification of urban park green space ecosystem disservices(PEDS),and introduces the influencing factors of the listed examples of urban PEDSs.It also discusses equilibrium relationship of the urban park green space service and disservice,and summarizes the research on urban PEDS to improve the meaning of human well⁃being.Finally,it points out the factors that should be considered in the planning,design,management,and maintenance of future urban park green space.

Study on the Distribution Characteristics and Influencing Factors of Park Green Space in Wuhan City

The distribution characteristics of park green space in Wuhan City were studied by standard deviation ellipse(SDE)method,average nearest neighbor index,kernel density estimation(KDE)method and scale index method.At the same time,the influencing factors of its distribution were discussed from three aspects of nature,social economy and culture with a geographical detector.The results show that(1)the distribution of park green space in Wuhan was relatively concentrated,and the directionality was not strong.The distribution mode was clustered mode.There were four main aggregation centers,which were located in Jianghan District,Qingshan District,Dongxihu District and Wuchang District respectively.Among them,the scale index of Jianghan District was the highest,up to 0.5902,while that of Xinzhou district was the lowest,only 0.0047.(2)The order of interpretation intensity of park green space distribution in Wuhan was population density(0.382)>regional GDP(0.278)>location of historical relics(0.165)>urbanization rate(0.136)>watershed zoning(0.069)>altitude(0.012).(3)The interaction of population density and watershed zoning had the strongest explanation for the distribution of park green space in Wuhan.Except for the influence of population density,the interaction of urbanization rate and regional GDP had the strongest explanation for the distribution of park green space in Wuhan.

Utilization Pattern of Olympic Parks and Its Application in Beijing

With great promotion of mega-events in both quantities and qualities in China, the research of Mega-events has been increased. As a global hallmark event, the Olympics, with their enormous scale, universal attraction for the media and tremendous political significance, have increasingly drawn attention from the researchers. It is obvious that Beijing has been greatly impacted by the 2008 Olympic Games as the host. The event aroused close attention of researchers, especially the problem how the Olympic stadiums and facilities can be utilized after Olympic Games. The paper employed 3 methods to conduct a survey, that is, sending questionnaires to tourists, in- terviewing with government officers, and collecting information about former Olympic Parks from Intemet and lit- eratures. The utilization of former Olympic Parks after Games was summarized and some experiences were refined. Besides, 3 main bodies including government, business operators and visitors which formed basic driving forces to influence the park＇s use were analyzed. At the same time, the paper believes that 3 topics affect the park＇s utilization involving ＇prepare to use＇, ~how to use it＇ and ~how to manage it＇, and Beijing Olympic Park can also follow that thinking and reference in the ft^her practices. Based on it, suggestions are given that Beijing Olympic Park can be planned spatially from 3 layers, the point, line and area, based on their function and infrastructure in the Games, and the area would be shaped as a new urban center with multi-functions while Mega-events and sport events are still the main content of the park.

The Scale-Effects of Different Land Use Types on the Distribution Pattern of Park Green Space at Multiple Grid Scales-A Case Study on the Main Urban Area of Nanjing,China

Exploring the scale-effect of different land use types on the distribution pattern of urban park green space(PGS)at multiple grid scales would inform rational allocation and efficient collaborative construction of urban development land at different scales.Selecting 300-m,500-m,1,000-m,and 2,000-m grid scales,the research employed Create Fishnet tool in ArcGIS and Geodetector to construct a scale-effect analysis framework that revealed the scale-effects of different land use types on the distribution pattern of PGS at multiple grid scales in the main urban area of Nanjing,China in 2006,2012,and 2017.Main research results are:1)the overall distribution pattern of PGS showed the evolution characteristics from polarization to advancing quality and efficiency,while the trend gradually weakened with the increase of grid scale;2)the scale-effect of other land use types on PGS increasingly enhanced-the larger the grid scale,the more obvious the synergistic or compressive effect;3)the interactive scaleeffects of different land use types gradually enhanced-the larger the grid scale,the more significant the overall factor interaction;and 4)at the 300-m grid scale,the major interaction factors were residential,transportation,industrial/manufacturing,water area,and administration/public services,which gradually changed to residential,water area,and administration/public services up to the 2,000-m grid scale.The findings of this paper are expected to deepen the theory of the coupling between PGS and other land use types,as well as provide scientific support and a basis for efficient allocation,spatial layout optimization,and sustainable development of urban spaces.

城市绿地系统规划中社区生活圈规划理念运用策略——以岳阳市为例

社区生活圈休闲空间配置效率关乎休闲空间能否满足居民美好生活的需要。从《城市居住区规划设计标准》提出“生活圈居住区”到《社区生活圈规划技术指南》提出“社区生活圈”,社区生活圈以公共绿地为主的休闲空间规划相关规定日趋完善;《城市居住区规划设计标准》明确了公共绿地配套规模和复合利用,《社区生活圈规划技术指南》拓展了休闲空间范畴、复合利用范围,《城市绿地规划标准》等标准规范从指标整合、设施设置两方面进行有效补充;但系列标准规定对休闲空间系统挖潜整合不深入、利用范围规定不完善、功能实现措施不到位,导致根据标准规范编制的城市绿地系统规划中休闲空间服务要素配置效率不高。选取3个城市近期编制的城市绿地系统规划案例进行分析,印证生活圈有关绿地标准规范解读结果。基于此,提出研究国土空间规划体系下城市绿地系统规划中社区生活圈规划理念高质量运用策略的思路,将休闲空间纳入公园体系,对规模、布局和功能进行系统性整合,并以岳阳为例进行实践,总结出城市绿地系统规划中“整理资源构建完整系统、复合利用提升效率品质、精准供给保障规模覆盖、规划指引控规精准继承”四大社区生活圈规划理念运用策略,保障休闲空间服务要素高效配置,以期为城市绿地系统规划中社区生活圈理念应用提供借鉴经验。

基于大语言模型绿电预测和绿电交易的园区综合能源系统集群多目标协同运行方法

为实现传统工业园区数字化和智能化升级,助力区域高质量发展,亟需园区智能化调度模型。为此,该文结合智慧园区管理系统和园区综合能源系统物理模型建立园区综合能源系统集群架构,提出了园区综合能源系统集群绿电交易三阶段协同运行方法,以解决多园区综合能源系统绿电交易的问题,实现分布式绿电的精准预测以及就地消纳。首先,基于大语言模型LLAMA-7B实现绿电预测,进一步以绿电功率划分购售电园区。其次,基于绿电价格配额曲线预测模型和动态绿电定价策略,制定园区间绿电交易差异价格。在此基础上,建立了多目标低碳经济优化运行模型,从而解决绿电交易所带来的经济因素和环境因素的矛盾问题。算例分析表明:所提出的模型可以统筹规划园区综合能源系统集群的经济成本、实际碳排放量和新能源利用率,对多园区综合能源系统的智能调度具有积极的推动作用。

工业园区清洁生产评价指标体系构建与应用

我国在重点行业清洁生产评价方面已开展了大量工作,但是工业园区清洁生产评价仍处于起步阶段,需要进一步开展理论研究和实践探索。本研究回顾了工业园区清洁生产评价方法的研究进展,分析了相关学术研究和标准制定存在的不足,基于国家层面已发布的工业园区绿色低碳发展领域相关评价标准,构建了包含6项一级指标和32项二级指标的工业园区清洁生产评价指标体系,并以此对我国华中地区X园区进行评价分析。结果显示,2020—2022年X园区的清洁生产水平整体呈上升趋势,并于2021年达到了清洁生产Ⅱ级水平,但是距离清洁生产先进水平仍有一定差距。针对清洁生产评价发现的问题,本研究提出了深化固体废物综合利用、改善园区空气质量、强化园区生态建设、完善清洁生产管理机制、加强清洁生产能力建设等对策措施,X园区有望在2024年达到清洁生产先进水平。该评价指标体系在X园区得到了较好的应用,具有一定的适用性和可操作性,可以为工业园区开展清洁生产评价提供参考,并为提升清洁生产水平提供决策支持,促进工业园区减污降碳协同增效和绿色低碳高质量发展。
