中国城市化与城镇居民住房

随着住房制度改革的不断深入,我国城镇居民人均居住面积有所提高,居住水平有所改善。但是,中国城市化发展的特点很容易造成城镇居民居住水平提高的假象。本文分析了造成这些假象的原因。

一种用粪便样方法估计林麝种群密度的新方法

数量(密度)特征是动物种群的一个重要特征，是定点研究一个野生种群生态的一项非常重要的基础工作．其数量和年龄结构为进一步分析其种群的密度、移动、巢域和核域，尤其是为种群动态提供依据，也是珍稀动物保护和资源动物管理利用的先行工作和重要组成部份．关于野生动物种群数量的具体统计方法，有不少的文章报道，然而从动物的空间分布格局来研究大型脊椎动物却较为少见，这主要是受研究方法的限制．为此，作者对此进行了改进，提出了一种新的研究方法：临时空间样方法，并将其应用到冶勒自然保护区林麝的数量调查研究中去．结果表明：(1)集聚分布指数CA=12．09，说明冶勒自然保护区的林麝有较高的集聚度；(2)林麝粪堆在野外的分布属于聚集分布，并与负二项分布拟合较好；(3)在冶勒自然保护区，生活有62～98只左右的林麝，其密度为：1．0～1．6只／km^2．林麝在冶勒自然保护区呈现聚积分布的原因是由于环境和人类活动因素造成的．图1表2参24     

The transformation of multi‐storey dwellings by self‐help: workers’ city,Helwan, Egypt

Self‐help extensions to government‐built housing are now accepted as a valuable addition to the housing stock in many third world countries. This paper describes self‐help extensions being made to five‐storey walk‐up flats in Helwan, Egypt, to provide more living space for households which have grown too large for the two rooms initially provided. It is argued that the cooperative effort and standard of construction are resulting in an acceptable new environment. Government response should be to encourage and guide such extensions wherever they occur.     

Adaptation of local building materials — a key to rapid housing development in Nigeria

There are some experts who are dealing with research on locally made materials for building in the Ministry of Housing and Works in Nigeria. It has been discovered in the Ministry that lateriate clays can be fired and used for building even two‐storey buildings depending on the firing and the pressure (Ogunbamwo, 1975). The Ministry has constructed a block of bungalows of low‐cost housing units with mud at Ikoyi, off Kingsway Road. No one will know that these houses are mud houses if not at closer inspection. Unfortunately, no effort has been made to continue or improve on this laudable adventure in Nigeria.     

RUNOFF POLLUTION FROM MULTIPLE FAMILY HOUSING1

ABSTRACT: Increasingly, residential development in urbanizing areas is accomplished by large housing projects, composed of clusters of townhouses or garden partments. It is hypothesized that the runoff from such developments should carry more pollution than that from the same number of housing units on separate plots, because the runoff is conveyed directly to drainage channels rather than being drained across lawns and gardens, which may absorb part of the pollutants. In order to evaluate this effect, storm event data were obtained from a planned unit development near Hightstown, N. J., using samples taken every 10 minutes throughout the storm at two different storm sewers. Results show heavy metals pollution about what had been anticipated, in accordance with the hypothesis given above, and BOD ammonia and phosphates higher than predicted. The results are significant for areawide water quality planning in metropolitan areas, where projections of future pollution loadings depends upon the land use.     

居住小区交通噪声概率分布特征及其评价

在连续35天监测的基础上，分析了道路交通流量的概率分布特征，发现道路交通流量在时间上呈对数正态分布。该分布导致小区交通噪声在时间上具有明显的正态分布特征，其中小区临街交通噪声在空间上也呈正态分布。将上述概率分布特征应用到小区道路交通噪声评价中，使得评价结果不仅具有一般的大小意义，还具有概率分布意义。     

“Housing for all” at the era of financialization; can (post-disaster) cities become truly socially resilient and egalitarian?

This paper examines the realism of the resilience ambition and process of the U.S. housing system, shedding light on its heterogeneity as well as the financialization currently acting as the driving force in real estate production. The resilience ambition leading to enhanced justice and egalitarianism is understood as the provision and maintenance of post-disaster housing for all within an institutionally diverse landscape of housing policy makers and implementers. Particular emphasis is given to the post-Katrina institutional transformations resulting from multifarious interactions between multilevel institutional structures and a diverse landscape of low-income housing policy implementers – referred as social resilience cells (SRCs) in this paper. The nature and level of these transformations determine the degree to which resilience in its heterogeneous form has been incubated in New Orleans. The paper concludes with a discussion on the macro conditions and bottom-linked governance structures under which all SRCs could be better bolstered in a post-financialization, radicalised neowelfare U.S., and which in turn create possibilities for materialising the resilience ambition.
