白城市环境保护“十三五”规划思路与主要任务

白城市是吉林省重要的防风固沙屏障,但是受客观存在的不利因素与多年来人为的不合理开发影响,生态环境仍然较为脆弱.“十三五”期间,立足白城生态环境实际,以提升环境质量为主线,以突出的环境问题为导向,以生态保护与修复为重点,实施河湖连通工程、造林绿化工程、土地整理工程、湿地保护工程、草原治理工程等5大工程.针对关系百姓切身利益的环境问题,以大气、水、土壤为重点,实施蓝天工程、清水工程、土壤恢复治理工程.健全生态制度,推进生态文明建设,实现区域环境质量得到较大提高和生态脆弱环境得到明显改善.     

旅游业发展规划的环境影响因素识别探讨

2003年《中华人民共和国环境影响评价法》,从法律上确立了中国在规划层次上需要环境影响评价.目前旅游规划环境影响评价工作处于初期阶段,其理论与技术性问题需要进一步完善.以哈尔滨市旅游业"十二五"时期发展的总体规划为例,针对旅游业发展规划的环境影响因素识别进行探讨,采用矩阵法识别旅游业发展规划项目与人们活动对哈尔滨市自然资源、景观资源、生态环境、环境敏感区及社会经济文化的可能产生影响环境因素识别探讨,给类似规划的环境影响因素识别工作提供帮助.     

水污染的防治对策及控制优化规划研究

水是人类生活和生产必不可少的资源,可是随着经济的快速发展,水污染问题也日益显露出来。水污染的治理与控制优化规划已成为当今环境治理领域重要的研究课题。本文主要阐述了水污染的原因,类型分析,危害,防治对策及其控制优化规划,并对以后的水污染治理进行了展望。     

土地利用改造规划的多因子空间分析

以福清市土地利用分布为例 ,在完成土地利用状况和土地适宜性参评因子空间数据库基础上 ,集成土地适宜性综合指数模型和地块紧凑度模型 ,开发了基于地理信息系统的土地适宜性评价和土地利用控制决策支持系统。通过土地适宜性多因子空间分析 ,模拟大农业 (耕地、林地、园地 )各目标用地条件下各地块土地使用适宜度 ,并结合土地利用现状 ,得到单目标土地改造方案 ;再经模型优化和综合比较得出多目标土地利用改造规划可选方案。计算结果表明 ,福清市土地资源中开发改造为新耕地的潜力极有限 ,而用于开发改造新林地和园地的土地尚有226 80km₂ 和36 34km₂ ,为福清市土地利用改造规划和总体规划的制定和调整提供了定量依据。     

省级区域耕地保有量测算研究——以江苏省为例

预测了江苏省耕地供给变化趋势和耕地需求量。根据预测结果，对耕地供需平衡情况进行了判断，分析了不同的耕地集约利用水平、耕地种植结构对耕地供需平衡的影响耕地的供需状况。以此为依据，确定了区域粮食供应的优选策略。在此基础上，从区间估计的角度，探讨了耕地保有量的确定思路与方法，确定了江苏省规划期内不同时间阶段的耕地保有量区间，即到2010年耕地保有量应维持439．7-473．0万hm^2，2020年耕地保有量应维持420．8-458．4万hm^2。     

“多规合一”开展现状及成效分析

在研究"多规合一"发展演变历程的基础上,深入剖析"多规合一"的内涵:"多规合一"是各类规划的统筹,是系统的空间管理,是简政放权的手段。从市级、省级两个层面,论述了广州、厦门、海南等试点城市"多规合一"开展的现状,比较各试点城市牵头部门、规划体系、发展步骤等发展模式的不同,总结"多规合一"开展以来在解决规划打架、盘活土地资源、缩短审批时间、实现资源共享、加强生态管控等方面取得的成效,梳理出开展过程中遇到的难点和问题,并展望下一步工作。     

Integrated environmental management: strengthening the conceptualization

Although espoused by many, integrated environmental management (IEM) has been difficult to accomplish in practice. There are many reasons for this shortfall, but certainly a key factor is the lack of agreement among scholars and practitioners regarding the concept and its defining elements. Our purpose here is to sharpen the conceptual basis for IEM by elaborating and pragmatically characterizing a framework for the practice of more integrated environmental management. We outline four fundamental dimensions of IEM: (1) comprehensive, (2) interconnective, (3) strategic, and (4) interactive/coordinative. IEM efforts in the Black Earth Creek watershed in Wisconsin illustrate specific attributes and examples pertaining to our conceptualization of IEM. Acceptance of the conceptual framework elaborated here should alleviate some of the confusion associated with IEM and help move this widely heralded approach from theory into practice.     

Towards an agile participatory urban soundscape planning framework

This paper presents an agile participatory urban soundscape planning process model, which is proposed as a prerequisite on which to build and reference the efficacy of urban soundscape planning. The model was developed through data synthesis and analysis and mapping engagement with diverse stakeholders across four applied soundscape projects in Brighton and Hove, UK. To the best of the authors’ knowledge, the model is the first of its kind in applied soundscape practice. The data was collected through semi-structured interviews with key stakeholders and document analysis of published resources. The framework used for the analysis of the findings comprised four core urban planning stages: goals and objectives, engagement (e.g. prediction/modelling/design/planning), implications, evaluation. The study found that when integrating soundscape planning with core urban planning stages it was necessary to first identify the appropriate stakeholders in relation to the project context. It was found that these stakeholders could be wide-ranging and unexpected, thereby reinforcing the appropriateness of incorporating an agile approach in the resulting model. The study also found that users’ perceptions are central to soundscape practice and need to be considered at each stage of a planning process to produce an effective and sustainable outcome. A variety of specific events, appropriate to the requirements of the stakeholders, are important for engaging planning authorities, users and other stakeholders at different stages. This study also demonstrated that an evidence-based evaluation method is recommended in an agile participatory urban soundscape planning process to assess stakeholders’ engagement at each stage and to inform and guide subsequent steps in the planning process relevant to the local context(s).     

海绵城市规划指标分解案例研究——以北京A新城为例

设计指标分解是海绵城市规划设计的重难点,但目前并没有统一的标准来指导实践.为探索海绵城市规划指标分解方法,以A新城海绵城市专项规划为例,将年径流总量控制率、控制容积作为控制性指标,下沉式绿地率、透水铺装率、绿色屋顶率和调蓄容积作为引导性指标,结合建设情况、汇水面种类及构成情况等条件,利用海绵城市规划设计辅助计算软件加权...
