The British road to post war planning: the forty‐year journey to the 1947 town & country planning act

This paper analyses the currents which gave rise to the 1947 Town & Country Planning Act. It describes the main statutory events in the first half of the 20th century and considers the progress made in implementing the legislation. It is argued that, while the 1947 Act was a major advance on what went before, it is not a significant departure.     

泗阳县黄河故道滩区综合开发模式研究和实践

1989年以来,泗阳县运用系统工程的方法,对黄河故道滩区洪涝沙碱旱的综合治理和滩区三荒资源的综合开发利用进行了研究和实践,创立了黄河故道滩区综合开发模式,缩短了开发周期,提高了开发效益,为黄淮流域季节性沙土河道滩区的治理开发树立了一个典范。本文将扼要介绍模式的提出、建立和实施效果。     

可持续发展中合理人口规模的研究：以苏南地区集镇为例

本文在分析农业人口转移数量、经济效益、社会商品销售额、集镇容纳能力的基础上,研究了集镇合理人口规模的界线。     

小城镇环境保护规划存在的问题与对策

根据全国生态环境保护“十五”计划要求,在计划期间力争60％的小城镇完成环境保护规划,广西小城镇由于经济发展不平衡,部分小城镇还比较落后,且存在较多的环境问题,目前小城镇的环境保护规划尚未得到有效的开展,因此应及时找出问题和差距,并根据存在的问题作出相应的对策,在计划期内是可以完成小城镇环境保护规划的目标,为广西小城镇的可待续发展提供环境保障。     

湘中地区恩口煤矿老采区复采的水害防治研究

湘中地区碳酸盐岩广泛分布,其中岩溶的发育受岩性、地貌、水文、构造运动等诸多因素的控制,主要分布在地下水排泄区,给煤炭资源的开发带来了严重水患。针对恩口煤矿水害问题,笔者在翔实的野外调查基础上,通过分析矿区水文地质条件、矿井水文地质特征;总结以往矿山防治水经验和教训;探讨今后老采区复采的防治水害方向和重点;认为壶天河的山口冲段、小碧河的西坪段、涟水河的杨家冲段等为重点防区,对河床铺底强度不可靠的部位应该重新加强铺底。     

THE CIRCUIT RIDING ORDINANCE ADMINISTRATOR: A SOLUTION TO SMALL COMMUNITY TECHNICAL INADEQUACIES1

ABSTRACT: Small, rural communities (less than 2500 population) in general do not have governmental staffs with the breadth required to satisfactorily implement and enforce a drainage ordinance. This fact has serious implications in rural Planning. Within a six-country rural area of Southwest Virginia, the circuit riding town manager program has been successfully conducted. The circuit riding town manager is a planning staff member who acts in the capacity of a town manager (assistant to the mayor) for five small towns, any one of which alone could not afford to support the services of such a professional. This note recommends that a circuit riding technical ordiance administrator program could be developed along the same lines. In this manner, the technical ordinance program for serveral small communities could be successfully implemented.     

Ageism: A Factor in the Nutritional Vulnerability of Older People?

Unlike other population groups, the rights, needs and contributions of older people in developing countries are not well understood. With the absence of information about how to assess the nutritional status and vulnerability of older people, HelpAge International joined forces with the London School of Hygiene and Tropical Medicine in the early 1990s to launch a research programme. Seven years later some of the basic questions can now be answered but there remains much more to do.
Although older people are increasingly acknowledged as a vulnerable group in emergencies, NGO responses often fail to meet their needs. The question is whether there are real difficulties in service adaptation or whether ageism is one of the greatest barriers to the provision of appropriate services for older people.     

老垃圾填埋场渗滤液回灌工艺参数研究

根据理论分析,通过回灌能够实现对老垃圾填埋场所产生渗滤液的场内处理,改善渗滤液水质,同时能加速老填埋场的稳定化进程.以深圳市10座老垃圾填埋场为研究对象,提出渗滤液回灌工艺及其参数.回灌方式以水平渗沟为主,设置聚乙烯罐调节水量.渗滤液回灌加速了填埋气体产生速率,降低了有效应力,可能引起垃圾体边坡失稳.较大的渗滤液回灌量(1.6%)导致较低的垃圾边坡安全系数(1.96).确定满足加速垃圾稳定化和填埋场稳定性的最佳回灌量是填埋场渗滤液回灌大规模应用需要解决的重要问题.     

小城镇基准地价更新方法研究

基准地价评估及更新是目前土地管理的一项重要和经常性的工作。针对小城镇的土地利用特点，对小城镇土地定级估价更新中的地价样本祷点、土地级别调整、基准地价更新评估等方面进行了研究，选择级别界线修订法更新小城镇土地级别，并在此基础上探索出适合小城镇特点的基准地价更新方法。     

城市老工业区土壤重金属污染状况与健康风险评价

本文对西部某老工业区土壤中As、Pb、Cr、Cd、Hg、Zn的含量、空间分布状况展开了研究,并依据《污染场地风险评估技术导则》对该老工业区的健康风险进行了评价。研究结果表明,该老工业区土壤重金属污染严重,6种元素与陕西土壤背景值相比超标100%,表明其不适宜作为居住用地开发。健康风险评价结果显示,As、Pb、Cr、Cd元素的非致癌风险值分别为3.83、1.7、1.94、1.09,均超过非致癌风险可接受值1,表明该老工业区对人们存在非致癌健康风险;对于致癌风险,As、Cr、Cd元素的致癌风险值远大于致癌风险边界值,分别超过致癌风险值的2个数量级(2.64×10-4)、4个数量级(1.94×10-2)、1个数量级(6.12×10-5),表示As和Cr已经达到了显著致癌风险的水平。
