装修改造对结构整体安全性影响分析

归纳了危害结构安全的主要装修改造行为,提出装修改造对结构安全性影响应以整体结构为研究对象,分析结构整体抗力的变化。以实际工程为例,对装修改造前后建筑结构进行设计复核,重点分析了建筑荷载增加、承重墙窗下墙拆除对结构安全性的影响。指出在各种装修因素综合作用下,结构承重体系发生改变,尤其是抗震薄弱构件的出现,使结构整体抗震能力大大降低。提出保证建筑结构安全性的合理化建议,对防止突发性灾害具有重要意义。

城市空气质量达标规划的逻辑框架

针对环境空气质量达标规划目前没有明确规划编制的基本要求和主要内容之间的关联原则、未将长期规划方案落实到日常管理方案、过于重视长期空气质量目标与减排情景方案而对污染物减排方案重视不足、未将规划的成本效益分析作为主要方案设计依据等逻辑不清的问题,从人群健康的角度出发,构建达标规划的逻辑框架：提出空气质量目标和人群健康目标相一致的目标体系;设计与空气质量目标一致的污染物减排方案,通过成本效益或成本有效性分析明确优先序,按照重污染日（周）、重污染月、采暖期等优先序实施区域内污染物排放量的绝对减排,并落实到排污许可证中;实施空气质量“日”管理,根据预测模型对未来重污染天气进行污染源排放管理,并对污染源减排方案实施持续动态评估和调整.     

Improving protected area effectiveness through consideration of different human-pressure baselines

Previous assessments of the effectiveness of protected areas (PAs) focused primarily on changes in human pressure over time and did not consider the different human-pressure baselines of PAs, thereby potentially over- or underestimating PA effectiveness. We developed a framework that considers both human-pressure baseline and change in human pressure over time and assessed the effectiveness of 338 PAs in China from 2010 to 2020. The initial state of human pressure on PAs was taken as the baseline, and changes in human pressure index (HPI) were further analyzed under different baselines. We used the random forest models to identify the management measures that most improved effectiveness in resisting human pressure for the PAs with different baselines. Finally, the relationships between the changes in the HPI and the changes in natural ecosystems in PAs were analyzed with different baselines. Of PAs with low HPI baselines, medium HPI baselines, and high HPI baselines, 76.92% (n=150), 11.11% (n=12), and 22.86% (n=8) , respectively, showed positive effects in resisting human pressure. Overall, ignoring human-pressure baselines somewhat underestimated the positive effects of PAs, especially for those with low initial human pressure. For PAs with different initial human pressures, different management measures should be taken to improve effectiveness and reduce threats to natural ecosystems. We believe our framework is useful for assessing the effectiveness of PAs globally, and we recommend it be included in the Convention on Biological Diversity Post-2020 Strategy.     

污染场地风险管控可持续评价指标体系构建及关键影响因素分析

以可持续发展理论和风险管理理念为基本原则的污染场地可持续风险管控已成为当前国际社会场地管理的重要决策问题和研究前沿热点,为明确影响污染场地风险管控可持续发展能力的决定性因素,基于国内外污染场地可持续风险管控相关文献的系统调研,构建契合我国场地管理背景的区域污染场地风险管控可持续评价体系,通过指标综合权重计算判定影响风险管控可持续发展能力的关键因子.结果表明,区域尺度上可能影响我国污染场地风险管控可持续性的指标多达44个,涵盖环境、社会、经济和技术这4个维度,单指标影响程度为0.26%～5.01%(平均值2.27%).潜在风险和温室气体排放(环境指标)、健康与安全和公众参与(社会指标)、管控成本和环保投资(经济指标)、修复周期和修复效果(技术指标)是影响我国污染场地风险管控可持续发展的重要因子,影响程度为1.89%～5.01%(平均值3.58%).具有较强政策敏感性的指标,包括考核指标、投融资创新、名录管理、能力建设、安全利用和制度建设等,对风险管控可持续性已经产生1.18%～3.48%的正向影响,随着政策制度的深入落实与全面地域推广,其对风险管控可持续发展的助力效应将更加明显.

Toward sustainable livelihoods after war: Reconstituting rural land tenure systems

Land tenure plays a primary role in sustainable development efforts. However armed conflict and its repercussions reconfigure the network of social relations upon which all land tenure systems depend. In post‐conflict settings new laws have the opportunity to address tenure issues in the context of what people are already doing ‘on the ground’, with a view to moving from the fluidity of post‐conflict situations to a more solidified and peaceful social and legal environment. However there exists a lack of tools to analyze postwar land tenure and the prospects for reconstituting tenure systems to support recovery and development. This paper uses the Sustainable Livelihoods framework to examine postwar land tenure issues in order to draw out latent opportunities within emergent informal smallholder tenure constructs which may have utility in the reconstitution of national tenure systems.
