面向国土空间规划的科学性、可操作性、层级性等内涵,探讨了资源环境承载能力评价和国土空间开发适宜性评价(“双评价”)与国土空间规划之间的基本逻辑问题、应用挑战与应对方法。通过系统梳理“双评价”的理论发展和相关政策响应,剖析了“双评价”在应用探索、内涵扩充、系统支撑三个阶段的研究重点和服务目标,阐明了承载力评价与适宜性评价之间关联逻辑的演进历程。总结了当前“双评价”在应用上的几个关键挑战:一是“双评价”应用于“三区三线”划定的逻辑尚未明确;二是当前承载能力评价与未来规划决策之间存在逻辑悖论;三是“双评价”在不同层级国土空间规划中传导失灵;四是两个评价之间的关联逻辑仍存在争议。为此,提出了应对“双评价”挑战的四点建议:深化理论认知、拓展评价维度、建立传导机制、厘清内在关系,以提升“双评价”对国土空间规划决策的支撑能力。 相似文献

中国县域土地利用结构类型研究 总被引:24,自引:3,他引:24
论文简要阐述了土地利用结构和土地利用结构类型研究的意义,进而提出了土地利用结构类型划分的原则、依据。在此基础上,基于土地利用分县的详查数据,以全国2475个县域为基本单元,运用最小方差法对其进行了土地利用结构类型的划分。对初次分类结果进行分析,制定原则并对其进行处理,将定性分析与定量研究相结合,最终确立了一个由6个土地利用结构系列和44个土地利用结构类型构成的中国县域土地利用结构类型分类系统。最后,对中国县域土地利用主要结构类型的地域分异规律及开发利用方向进行了探讨。 相似文献

全球气候变化给人类社会文明带来严峻挑战,需要人类社会采取共同措施和行动积极应对。应对全球气候变化是当今世界最能体现人类共同命运的领域,深度参与并积极推动全球气候治理体系改革和建设是中国推动构建人类命运共同体的重要实践,也是生态文明理论和实践的重要方面。应对气候变化是我国生态文明建设的重要内容和内在要求;以共同价值理念构建人类命运共同体,凝聚各国力量携手合作应对全球气候变化,是全球生态文明建设和构建人类命运共同体的具体实践,也为应对全球气候变化提供了良好载体和国际平台。文章通过分析可知,应对气候变化、生态文明建设与构建人类命运共同体三者之间,呈现出相互促进、和谐共生的"三位一体"特征;人与自然共生的生命共同体是前提条件,人类的任何实践活动都要以自然生态系统为基础和前提;人类命运共同体在整合各国力量方面,为生态文明建设提供了社会基础;生态文明包容各国文明,凝聚价值共识,成为生命共同体和人类命运共同体的价值导向。中国倡导人类命运共同体理念,是全球生态文明和人类命运共同体的积极倡导者、推动者和践行者,既为应对全球气候变化提供了价值基础,也提供了强有力的实践支撑;应对气候变化是全球生态文明建设和人类命运共同体构建的生动实践。因此,加强生态文明建设和构建人类命运共同体,为全球应对气候变化提供了理论基础和国际平台,也将为全球可持续发展贡献中国智慧和中国案例。 相似文献

This study aims at describing, analyzing and evaluating the relation between management styles and process dynamics of a complex planning process confronted with unexpected dynamics. The development of an aquatic disposal site for dredged contaminated sediments in Oslo was managed by a project management style focused on timely and cost-effective implementation. Coupling the remediation project with another infrastructural project and the actual construction of the site led to unexpected dynamics in terms of resistance and controversy. Project management had difficulties in adjusting its style accordingly, resulting in even more delay and resistance. Managing complex planning projects requires a style suitable to the characteristics of the project and the capability of adjusting it to changing circumstances. The paper concludes with some explanations why it is difficult to change management styles in complex planning and implementation processes and complexity-embracing approaches to deal with this. 相似文献

将突发事件应对能力分为一般应对能力和特殊应对能力,以大学生为样本编制量表,在社会居民中验证其适用性,量表有良好的信效度和适用性。对浙江省11个地区的居民抽样调查表明,积极行为能力强于情绪管理能力,传染疾病和火灾应对能力比较强,食物中毒应对能力比较弱;城市居民强于农村居民,男性比女性强;社会居民强于大学生,50岁以下的比较强;机关干部最强,农民最弱;受训者强于未受训者,受训者太少。突发事件应对训练竭待加强。 相似文献

Our study examines how personality and coping influence soldiers' psychological health among 648 US Army personnel who were at that time deployed in Iraq at the height of an insurgency. Conscientiousness, neuroticism, and extraversion were associated with different coping behaviors, and these were in turn related to psychological distress. Conscientiousness was positively associated with problem‐focused coping and negatively with avoidance coping, whereas neuroticism was most positively associated with avoidance coping. Extraversion was positively related to both seeking social support and avoidance coping. As expected, avoidance coping was positively associated with psychological distress. Coping style explained more variance in the relationship between personality and distress among soldiers who perceived higher levels of threat, thus supporting a moderated mediation hypothesis. We discuss implications for facilitating the stress coping of workers who face acute and potentially traumatic stress exposures. Copyright © 2011 John Wiley & Sons, Ltd. 相似文献

This paper explores the level of vulnerability to the hazard of fire that exists in Makola Market in Accra, Ghana, and assesses how this threat can be reduced through a community‐based risk assessment. It examines the perceptions of both market‐stall occupants and primary stakeholders regarding the hazard of fire, and analyses the availability of local assets (coping strategies) with which to address the challenge. Through an evaluation of past instances of fire, as well as in‐depth key stakeholder interviews, field visits, and observations, the study produces a detailed hazard map of the market. It goes on to recommend that policymakers consider short‐to‐long‐term interventions to reduce the degree of risk. By foregrounding the essence of holistic and integrated planning, the paper calls for the incorporation of disaster mitigation measures in the overall urban planning process and for the strict enforcement of relevant building and fire safety codes by responsible public agencies. 相似文献

为了研究逃生者在疏散标识引导下的火灾疏散效率与逃生认知应对规律,基于实地调研与问卷调查结果,采用Anylogic软件,对常规标识与增设标识2种教学楼火灾疏散情境进行仿真模拟。研究结果表明:在疏散过程中,增设标识能使各疏散出口的疏散时间相对持平,避免了常规疏散中通道过早闲置的现象;人流在一层教学楼的平均疏散时长缩短了约10%,显著缩短了整栋教学楼的疏散时间。据此火灾标识疏散仿真过程与人的认知反应提出了火灾疏散与标识认知应对规律模型。 相似文献
