南通市矿产规划编图中河道淤泥资源要素表达方式

在矿产资源种类单一的南通地区,砖瓦用黏土是其矿产资源规划的主体,基于保护耕地和环境的需要,全部利用河道淤泥作为砖瓦用黏土资源。因此,在该市矿产资源规划图件编制中,需要解决这一特殊的非传统矿产要素的表达问题;通过探索,采用概化综合属性、以点代面的表达方式,较为准确地反映了淤泥资源的分布、可用量及规划开发量等要素。     

绍兴市地质灾害易发分区研究

为了对绍兴市的地质灾害易发风险性进行定量评估,本文借助GIS软件对绍兴市进行网格划分,构建地质灾害易发风险性评价指标体系和指数评价模型。通过对地质灾害进行定量评估,将绍兴市地质灾害易发程度划分为高、中、低、不易发4个等级,并绘制了绍兴市地质灾害易发性分区成果图。研究成果支撑绍兴市地质灾害防治“十四五”规划,服务于绍兴市的地质灾害防治管理和决策。     

Excel结合CAD软件在矿产勘查中的应用

针对目前矿产勘查、储量核实中,储量估算结果块段多、数据杂,最后其估算数据及各项参数均须在图上以估算结果圈的形式表达,按常规方法在CAD中处理效率低,特别对于各块段各项数据的标注通过复制已有估算结果圈来修改容易出错的特点,讨论Excel结合CAD软件快速自动生成储量估算结果圈的方法,为处理相类似的数据提供参考。

MUSLIMS,HINDUS, AND SIKHS IN THE NEW RELIGIOUS LANDSCAPE OF ENGLAND*

ABSTRACT. This article examines the dramatic changes brought to English townscapes by Islam, Hinduism, and Sikhism. These “new” religions have arrived with the large‐scale immigration and subsequent natural growth of the minority ethnic populations of Great Britain since the 1950s. The article traces the growth and distribution of these populations and religions, as well as the development of their places of worship from front‐room prayer rooms to cathedral‐scale buildings. It explores the way in which the British planning process, dedicated to preserving the traditional, has engaged with the exotic.     

Uncertainties in global warming science and near-term emission policies

Abstract

It is argued here that stringent, early emission reductions are necessary in order to minimize ‘dangerous anthropogenic interference in the climate system’ (DAI), the stated Objective of Article 2 of the UNFCCC (United Nations Framework Convention on Climate Change). Given probability distribution functions (pdfs) for climate sensitivity and the temperature threshold for harm consistent with currently available evidence, and accepting a 10% risk of unacceptable damage as the threshold for ‘danger’, it is not possible to avoid DAI. Having adopted a precautionary approach in setting emission trajectories, the possibility arises that future resolution of uncertainties concerning climate sensitivity and the harm threshold may show the climate sensitivity to be low (1–2 K) and the harm threshold high (2 K rather than 1 K). Using a simple coupled climate-carbon cycle model, it is shown that if the climate sensitivity were to be definitively determined to be 2 K in 2020, then the emission reductions achieved by that time and planned for the next two decades are still fully needed. Only if climate sensitivity is very low (1 K) and the harm threshold is high (2 K) would the emissions achieved by 2020 not have been fully necessary. However, this would still lead to changes in ocean chemistry that are likely to be highly detrimental to marine life. Thus, when the full spectrum of impacts is considered, there is no plausible set of assumptions under which stringent near-term emission reductions are rendered unnecessary.     

Constraining and enabling factors to using long-term climate information in decision-making

We carry out a structured review of the peer-reviewed literature to assess the factors that constrain and enable the uptake of long-term climate information in a wide range of sectoral investment and planning decisions. Common applications of long-term climate information are shown to relate to urban planning and infrastructure, as well as flood and coastal management. Analysis of the identified literature highlights five categories of constraints: disconnection between users and producers of climate information, limitations of climate information, financial and technical constraints, political economy and institutional constraints and finally psycho-social constraints. Five categories of enablers to the uptake of long-term climate information in decision-making are also identified: collaboration and bridge work, increased accessibility of climate information, improvement in the underlying science, institutional reform and windows of opportunity for building trust.

Policy relevance

Our review suggests that stand-alone interventions aimed at promoting the uptake of climate information into decision-making are unlikely to succeed without genuine and sustained relationships between producers and users. We also highlight that not every decision requires consideration of long-term climate information for successful outcomes to be achieved. This is particularly the case in the context of developing countries, where the immediacy of development challenges means that decision makers often prioritize short-term interventions. Care should therefore be taken to ensure that information is targeted towards investments and planning decisions that are relevant to longer-term timescales.
