Co-ordination for disasters

This paper was prepared in 1978 on the basis of a review of sociological and anthropological fieldwork conducted up to that time. Although theoretical in presentation its conclusions are formulated in accordance with the author's own extensive observations of organizational response to natural disasters in developing countries, especially those having sudden onset. Practical implications for co-ordination agencies and pre-disaster training are drawn.     

面向国土空间规划的“双评价”：挑战与应对

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。     

生态文明视角下的国土空间底线管控：“双评价”与国土空间规划监测评估预警

生态文明新时代下的空间规划体系对国土空间底线管控提出了明确要求,“双评价”与国土空间规划监测评估预警是底线思维的体现。研究“双评价”与国土空间规划监测评估预警在国土空间底线管控中的作用和地位,通过国土空间规划“一张图”实施监督信息系统的建设,对二者的联系及其相互作用进行体现,构建二者的联动方式,服务于国土空间底线管控及治理的全过程。“双评价”与国土空间规划监测评估预警共同组成底线管控的两个阶段,前者是开展底线管控的基础,后者是底线管控的路径和手段,两者皆是生态文明新时代下国土空间规划底线管控的重要工具,需以国土空间规划“一张图”实施监督信息系统为基础加强两者的有机结合。

魅力国土空间:重塑区域特色的国土空间规划策略

国土空间规划的提出使我国的规划体系进入到新的发展时期与发展语境,国土空间开发方向已从生产空间为主导转向生态、生活、生产空间相协调。如何将基于“三生空间”概念的传统国土空间认知提升到丰富文化脉络、生态特征、生活基础的复合魅力国土空间,如何对不同区域的发展进行侧重,杜绝对单一发展模式的盲目跟风,是国家和地方面临的共同重大主题。结合国土空间在历史与现实不同时期的发展表征和形成原因,在回溯空间认知过程、反思空间规划实践的基础上,厘清了魅力国土空间的概念与内涵,提出国土空间规划体系下魅力国土空间的关注焦点,从区域发展平衡、管控弹性调整、空间要素流动、发展目标优化等方面阐述了魅力国土空间的作用与功能。     

国土空间规划新时代旅游规划的定位与转型

我国已经迈入以国土空间规划引领“多规合一”的空间治理新时代,对各专项规划的管控约束性更严、技术性和衔接性要求更高。为此,本文重新审视了旅游规划的性质和地位,并基于产业专项性和空间融合性特征,将旅游规划分为战略规划、协调规划、发展规划和开发规划。以旅游发展规划为示例,提出了六大转型:规划理念从无限思维向边界思维、融合理念和空间思维转变,编制思路从甲方意志向市场导向转变,规划内容从大而全向专而精转变,技术路线从概念逻辑向空间逻辑转变,规划方式从封闭向开放转变,规划技术从缺乏技术到技术融合转变以期推动旅游规划衔接和融入新时代国土空间规划体系,进一步引领中国旅游产业的转型升级和高质量发展。

Cumulative effect assessment in Canada: a regional framework for aquatic ecosystems

Sustainable development of the aquatic environment depends upon routine and defensible cumulative effects assessment (CEA). CEA is the process of predicting the consequences of development relative to an assessment of existing environmental quality. Theoretically, it provides an on-going mechanism to evaluate if levels of development exceed the environment's assimilative capacity; i.e., its ability to sustain itself. In practice, the link between CEA and sustainable development has not been realized because CEA concepts and methods have developed along two dichotomous tracks. One track views CEA as an extension of the environmental assessment (EA) process for project developments. Under this track, stressor-based (S-B) methods have been developed where the emphasis is on local, project-related stressors, their link with aquatic indicators, and the potential for environmental effects through stressor-indicator interactions. S-B methods focus on the proposed development and prediction of project-related effects. They lack a mechanism to quantify existing aquatic quality especially at scales broader than an isolated development. This limitation results in the prediction of potential effects relative to a poorly defined baseline state. The other track views CEA as a broader, regional assessment tool where effects-based (E-B) methods specialize in quantification of existing aquatic effects over broad spatial scales. However, the predictive capabilities of E-B methods are limited because they are retrospective, i.e., the stressor causing the effect is identified after the effect has been measured. When used in isolation, S-B and E-B methods do not address CEA in the context necessary for sustainable development. However, if the strengths of these approaches were integrated into a holistic framework for CEA, an operational mechanism would exist to better monitor and assess sustainable development of our aquatic resources. This paper reviews the existing conceptual basis of CEA in Canada including existing methodologies, limitations and strengths. A conceptual framework for integrating project-based and regional-based CEA is presented.     

Linking Land Cover and Water Quality in New York City’S Water Supply Watersheds

The Catskill/Delaware reservoirs supply 90% of New York City’s drinking water. The City has implemented a series of watershed protection measures, including land acquisition, aimed at preserving water quality in the Catskill/Delaware watersheds. The objective of this study was to examine how relationships between landscape and surface water measurements change between years. Thirty-two drainage areas delineated from surface water sample points (total nitrogen, total phosphorus, and fecal coliform bacteria concentrations) were used in step-wise regression analyses to test landscape and surface-water quality relationships. Two measurements of land use, percent agriculture and percent urban development, were positively related to water quality and consistently present in all regression models. Together these two land uses explained 25 to 75% of the regression model variation. However, the contribution of agriculture to water quality condition showed a decreasing trend with time as overall agricultural land cover decreased. Results from this study demonstrate that relationships between land cover and surface water concentrations of total nitrogen, total phosphorus, and fecal coliform bacteria counts over a large area can be evaluated using a relatively simple geographic information system method. Land managers may find this method useful for targeting resources in relation to a particular water quality concern, focusing best management efforts, and maximizing benefits to water quality with minimal costs.The United States Environmental Protection Agency through its Office of Research and Development funded and managed the research described here. It has been subjected to Agency’s administrative review and approved for publication as an EPA document.
