运用分形理论从等级规模和空间结构两方面探析了粤西地区城镇体系结构特征。研究结果表明,粤西城镇等级规模分维数q为0.9884〈1,说明粤西地区城镇规模等级结构较为分散,首位城市的垄断性弱,小城镇数目较少,处于中间位序的城镇数目较多,城镇体系结构不完善。城镇空间关联维数D为0.9304〈1,说明粤西地区的城镇体系在空间分布上比较集中,空间联系较为紧密,城镇之间具有加强联系、共同发展的先天条件。据此提出了粤西地区城镇体系发展的建议。  相似文献

以人口规模作变量.运用城镇体系的异速生长模型和Zipf维数模型,分析了1984-2001年湖州市城镇体系时空结构的生长状态,结果表明,在一个中心城市相对弱小、自然资源基本均匀分布、主导产业为劳动密集型产业区域内,中心城市并无竞争优势,相反由于次级城镇资源人口集聚的低成本,资源人口集聚速度高于中心城市,最后资源和人口在体系内均匀分布,区域无法形成具有较强竞争力的增长极,从而影响整个区域的可持续发展,为改变这种状况,政府必须采取相应措旌,使区域城镇体系时空结构生长呈优化的分形状态,促进整个区域的可持续发展。  相似文献

浦北县系广西钦州市的市辖县,目前的城镇化水平尚处在城镇发展的极化阶段,其城镇空间格局呈现出散点状分布,且密度偏小、缺乏高首位度城镇、城镇沿公路交通干线及江河分布的格局较明显。影响城镇空间格局的因素主要是自然条件的制约、城镇发展的基础脆弱及区域基础设施的牵引等,但浦北县城镇发展的动力较明显,具体表现为水果资源动力、乡镇企业动力、农业综合开发动力等。从浦北县的城镇空间格局现状来看,浦北县的城镇发展应采用梯度推移战略、培育和强化增长极策略、协调发展战略及点——轴开发战略等。可以预见,随着浦北县经济实力的提升,其城镇发展将从极化阶段向集聚——扩散阶段推进。  相似文献

基于城市体系的分形理论,从等级规模和空间结构两个方面对该区的城镇体系分布特征进行了研究.结果表明,山东省沿黄地区济南的城市地位垄断性较强,其他中等城市不够发育,沿黄地区城镇之间通达度较好,但由于黄河阻隔及区域经济联系的地区差异,城市体系空间结构欠理想.提出了该区城镇体系的发展策略:适当扩大中心城市,培育次级中心城市;大力发展港口和铁路交通,区内与区外的经济联系.  相似文献

通过对广东省番禺市城镇污水的调查研究,获得了三角洲河网地区城镇污水的水量、水质变化特征以及水污染特征:工业废水地域分布趋于分散,行业分布更加广泛,排放总量逐年递减;生活污水排放总量逐年递增;城镇污水中,污染物含量较低,BOD5/CODcr比值偏小;大量未经处理的城镇污水的直接排放以及河网地区潮流的顶托作用,使该地区部分河段水质恶化,进而影响到水源地水质.针对上述问题,提出了7条污水治理对策,以探讨实施三角洲河网地区区域水环境可持续发展战略的途径  相似文献

In this introductory article, I argue why this special issue focuses on the question of how the mathematical knowledge required at work can be characterised and developed in vocational education and workplace training. After some words on the importance of this subfield of mathematics education and the need to rethink metaphors of learning in this area, I summarise the structure of the special issue and highlight a few main points raised in the various contributions.  相似文献

In order to obtain maximum benefits from the educational system, it is imperative that the system should work as a unified coherent unit. Gaad, Arif and Scott (2006) conducted the systems analysis of the United Arab Emirates' (UAE) general education system. They analysed three components of the system in order to assess the development, delivery and evaluation. This paper utilises the same framework to analyse the special needs education (SEN) system in the UAE. Data for the research were collected through observations and semi-structured interviews. Analysis of the data identifies some possibilities for improvement. In the area of development, more teaching and supplemental material specific to special needs education needs to be developed. Currently, teachers are working with what is known as the 'para curriculum'. It is based on the regular textbook; with chapters that are difficult being simplified or removed. In the area of delivery, more training would be beneficial to teachers. The monitoring and evaluation component's analysis points out that the evaluation instrument used currently needs to be modified for special needs education monitoring and additional resources in the area of special needs education would required.  相似文献

A MODEL PROGRAM, the Administrators’ Roundtables, was developed to increase the leadership of school principals in special education. The program was designed to meet the individual needs of participants as well as provide information regarding “best practices” in the field of special education. The one‐year program components include a series of monthly roundtable sessions where principals discuss relevant topics, distribution of professional materials and information, and participant site visits to model special education programs. An evaluation of the program is given based upon a questionnaire presented to the special education staff of participants before and after they became members of the Roundtable and an interview with a sample of the participants in the program. Results indicated that the Roundtables have had a positive impact on principals’ awareness and knowledge in the area of special education policies and practices with some secondary, indirect effects on programs for students with handicaps.  相似文献

《Support for Learning》2005,20(3):129-134
In this article Lynne Meiring and Nigel Norman focus on the notion of entitlement and the demands this has made on schools and teachers to cater for the needs of a wide range of pupils previously denied an experience of foreign languages. In order to enable all pupils to realise their potential, facilities and strategies have to be reviewed and developed to ensure that their learning experience is appropriate. This article focuses on the contribution that one such facility, namely information and communications technology (ICT), can make towards removing some of the barriers to learning experienced by some pupils, enabling them to realise some of the benefits of what has often been perceived as a particularly inaccessible curricular area. The authors examine how the generic capability of ICT can enhance and enable the learning of pupils with special educational needs (SEN), but do not purport to consider specifically the specialised technology required for certain manifestations of special need.  相似文献

Because of the diversity of the 6 countries concerned, the contributions in this special issue both inform and challenge us about the contribution and the place of special education research. In this brief commentary, I put forward some reflections on the function, funding, and subject matter of special education research, on research on the education of teachers in special education, and on some possibilities for research and its application in traditional and less developed systems.  相似文献

Since 1980 when Zimbabwe obtained political independence, special education has not received the same priority as the entire education system. One of the manifestations of this discrepancy is the shortage of qualified special education teachers in the country. In order to address this trend and promote the development of special education, researchers have suggested the need for professional development in the area of special education. The purpose of this study was to identify the special education professional development needs of both special and general education in-service teachers in Zimbabwe. A semi-structured survey instrument, developed by the first and second authors, which included open- and closed-end questions was used in this study. The sample consisted of 204 schoolteachers drawn from two school districts of Zvishavane and Gwanda. The participating schoolteachers overwhelmingly expressed the need for more professional development in the area of special education. The schoolteachers also identified several topics that they considered to be important for professional development.  相似文献

抗渗性混凝土是一种有着特殊性能的混凝土,除具备一般混凝土的基本性能以外,较高密实度,是其特有的性质.因而可以用于特殊部位,一般多用于地下防水性与承载性相结合的结构或构件中.作者根据多年的理论研究与实践,将抗渗性混凝土的相对较高的密实度这一特点,应用于一个崭新的领域——抗渗性混凝土在有气密性要求的混凝土粮食筒仓中的应用,并取得了良好的效果.  相似文献
