浅谈城市生活垃圾综合处理工程的总体规划设计

成功的总体规划是保证工程正常运行的前提。本文试图通过工程实例说明在进行环保工程的总体规划时，更应根据生产工艺、物料走向、防火及环境保护等结合厂(场)区的地质和气象等自然条件进行统筹安排，力求做到布置合理，达到建设快、投资省、运行经济安全的目的。     

MODELING FRAMEWORK FOR MANAGING COPPER RUNOFF IN URBAN WATERSHEDS1

ABSTRACT: A modeling framework was developed for managing copper runoff in urban watersheds that incorporates water quality characterization, watershed land use areas, hydrologic data, a statistical simulator, a biotic ligand binding model to characterize acute toxicity, and a statistical method for setting a watershed specific copper loading. The modeling framework is driven by export coefficients derived from water quality parameters and hydrologic inputs measured in an urban watershed's storm water system. This framework was applied to a watershed containing a copper roof built in 1992. A series of simulations was run to predict the change in receiving stream water chemistry caused by roof aging and to determine the maximum copper loading (at the 99 percent confidence level) a watershed could accept without causing acute toxicity in the receiving stream. Forecasting the amount of copper flux responsible for exceeding the assimilation capacity of a watershed can be directly related to maximum copper loadings responsible for causing toxicity in the receiving streams. The framework developed in this study can be used to evaluate copper utilization in urban watersheds.     

A grey multi-objective programming approach for sustainable land-use in the Miyun Reservoir basin, China

Miyun Reservoir is the most important water source to Beijing City. Land-use of the basin plays a great role in the protection of water resources. Hence a sustainable land-use planning is required to optimize land-use structure and protect water resources in the basin. Based on the complete land-use system analysis in Miyun, a grey multi-objective programming to basin land-use(GMOPBLU)model was developed and applied to land-use planning. Two alternatives were produced and analyzed by means of interactive adjustment and scenano analysis. The results showed the GMOPBLU model is a valuable approach for basin land-use planning.

基于GIS的城市火灾风险评价及其在防灾规划中的应用

随着经济发展和城市化进程的不断加快,城市火灾事故不断增多,造成的人员伤亡和财产损失也越来越严重。本文通过构建城市火灾风险评价指标体系,利用GIS中的空间分析功能对各指标体系按其权重进行叠加,得出城市的现状火灾风险等级区划图。根据风险评价现状确定防灾减灾规划的目标,采取相应的防灾减灾措施,并对规划后的火灾风险状况进行了预测,得出规划后的火灾风险等级,从而为消防和规划部门减少和预防城市火灾提供依据和参考。     

淮南市城市综合防灾规划简介

随着我国城市化进程的加快,自然灾害和事故灾害的发生给人民生命财产和城市经济带来的损失日益增大。以淮南市为例,探索了编制城市综合防灾规划的技术方法。规划在现状调研、灾害风险评估和用地安全评价的基础上,对应急指挥系统、应急通道、避难场所、应急物资保障等城市应急设施进行了规划布局;对防洪、抗震、消防、人防、地质灾害、突发水环境事故等防灾专项规划提出了指引;另外,规划也提出了防灾基本对策和实施措施。     

城市避难场所的规划建设和管理

城市避难场所是城市抗震防灾体系的重要组成部分,分析我国避难场所实施过程中出现的一些问题,提出科学规划避难场所,规范有序推进避难场所建设,做好避难场所维护管理,提高城市综合防灾能力,最大限度减少地震等突发灾害造成的人员伤亡和财产损失。     

气候变化背景下城市综合防灾规划自适应研究

探讨了城市总体规划层面如何进行气候适应性考量,提出在气候变化背景下自适应的城市综合防灾规划策略应全面渗透到城市总体规划的关键规划要素,尤其是土地使用规划和各专业系统规划中,而不应仅仅提出一些传统、孤立的应对措施。气候变化会导致潜在不适宜开发建设的用地范围大幅增加,加强论证气候变化对用地适宜性的影响,适度扩大禁建区和限建区的范围,是有效预防各类气象灾害及次生灾害的前提。各专业系统规划技术规范需加紧修订,突破传统思维,不能完全孤立地考虑单一的规划目标,进行气候适应性调整,并要积极预防不适应气候变化的已建人工构筑物成为事故灾害源。     

Disaster mental health training programmes in New York City following September 11, 2001

The need for mental health resources to provide care to the community following large‐scale disasters is well documented. In the aftermath of the World Trade Center (WTC) disaster on September 11, 2001, many local agencies and organizations responded by providing informal mental health services, including disaster mental health training for practitioners. The quality of these programmes has not been assessed, however. The National Center for Disaster Preparedness at Columbia University's School of Public Health reviewed disaster mental health training programmes administered by community‐based organizations, professional associations, hospitals, and government agencies after September 11. Results indicate that the quality and the effectiveness of programmes are difficult to assess. A wide range of curricula and a widespread lack of recordkeeping and credentialing of trainers were noted. Most of the training programmes provided are no longer available. Recommendations for improving the quality of disaster mental health training programmes are provided.     

Ecosystem services in infrastructure planning – a case study of the projected deepening of the Lower Weser river in Germany

We consider how ecosystem services can be incorporated into water infrastructure planning by studying the projected deepening of the Lower Weser river channel in Germany. We recalculate the project's benefit–cost ratio by integrating the monetary value of changes in different ecosystem services, as follows: (1) the restoration costs of a mitigation measure for a loss in fresh water supply for agricultural production in the estuary region, (2) the costs of a loss in habitat services, transferring the willingness to pay from a contingent valuation study to the area assessed in the environmental impact assessment, and (3) the benefits of emissions savings induced by more efficient shipping, taking a marginal abatement cost approach. We find that including monetary values for ecosystem service changes leads to a substantial drop in the benefit–cost ratio. On this basis, we argue for a reform of the standard cost–benefit analysis to facilitate more complete welfare assessments.
