镇(乡)域规划是在我国推进健康城镇化和城乡统筹战略的大背景下提出的,是《城乡规划法》规定的镇规划和乡规划的一种形式,其规划区范围覆盖镇乡行政辖区的全部。空间利用布局、空间管制和居民点体系规划是镇(乡)域规划中具有基础性的重要内容。然而,我国村镇空间基础数据的缺乏给镇(乡)域空间利用布局和管制的实际操作带来困难,居民点体系规划则存在依靠主观判断、缺乏科学依据的问题。针对上述问题,论文对RS和GIS技术在镇(乡)域规划中应用的必要性和可行性进行了分析,并结合河北省曲阳县产德乡乡域规划实践,探索在镇(乡)域规划中引入RS和GIS技术:(1)通过遥感影像解译、空间利用数据库的建立以及与土地利用规划的协调,实现镇(乡)域空间利用布局和管制;(2)通过30分钟和60分钟可达性分析分别确定村民耕作半径和中心村服务半径,提高居民点体系规划的科学性。在此基础上,论文对RS和GIS技术在镇(乡)域规划中的整体应用技术路线进行了总结和设计。 相似文献

随着国家对农村地区发展的重视程度不断加深,乡村发展成为当前热烈讨论的话题,空心村作为我国乡村发展历程中所特有的现象,得到了广泛关注。本文以保安镇土地、产业、资源、人口四个方面的困境为导向,立足于我国空心村整治研究现状,探讨基于空心村治理的镇域空间管制规划路径。以空心村治理为指向,提出完善管制体系、发展特色产业、均衡城乡资源三大空间管制策略,以缓解空心村在镇域层面治理的困境,为镇域层面治理空心村提供新思路。 相似文献

镇域村镇体系规划中产业空间定位分析 总被引:1,自引:0,他引:1
建制镇量大面广,既处于我国城镇体系中的最基层,又直接带动与服务于农村经济社会的发展,因此建制镇既有城市的产业集聚与中心职能,又有发展与服务于农业等任务;村庄亦具有一定的地域空间范围及组织经济社会发展的职能,它是建制镇规划的基本单元。所以,建制镇总体规划尤其是在镇域村镇体系规划中应体现这一特点并逐渐向上述发展目标诱导。 以镇城区与村域为单元的镇域村镇体系规划主要应明确镇区与村域产业发展方向、社会化服务设施与基础设施配套、人口分布与调整、耕地保护与土地利用以及镇域村镇整体上上述内容的结构与布局。在镇域村 相似文献

一、建立健全城乡一体的规划体系 近年来,在规划编制工作中十分注重在空间上要打破城乡分割,从区域整体出发,妥善处理城镇建设和区域发展的关系,统筹安排区域基础布局,避免重复建设,限制不符合区域整体利益和长远利益的开发活动,逐步建立省域城镇体系规划、分片城市群空间发展战略规划、城市总体规划、县(市)域总体规划、乡(镇)域总体规划和村庄总体规划,以及相应层次的专项规划和详细规划组成的城乡空间规划管制体系;在时间上要突破现有规划期限的限制,妥善处理城乡规划的战略性与可实施性之间的关系,更加注重城乡规划实施的系统性和计划性,建立战略规划、总体规划、近期建设规划和年度项目规划组成的城乡规划实施行动计划体系.各层次的规划要突出重点,明确强制性内容,逐步形成纵向衔接、横向协调,层次分明、管制有效的城乡规划体系. 相似文献

一、研究区域基本现状新疆地处欧亚大陆腹地,地貌轮廓表现为“三山夹两盆”,山地与平原的面积大致各占50%,镶嵌于戈壁沙漠的绿洲仅有7万平方公里。新疆土地面积166.49万平方公里,占全国总面积的六分之一。气候干旱,荒漠广布,是中国最大的干旱区,是亚洲干旱核心区,也是世界上著名的干旱区之一。水资源短缺,生态极度脆弱。新疆2004年底有1950万人,人均GDP已经超过了1000美元,城镇化进入了快速发展阶段,特别是小城镇的发展速度较快。但新疆特殊的干旱区绿洲环境,使得小城镇的发展存在许多问题。一是城镇规模小而散,基础设施配套差,城镇集散和… 相似文献

Nearly 1500 urine samples were collected from female farmers in eight regions widely scattered in the islands of Japan in the winter of 1987-1988. The samples were analysed for manganese by wet ashing and flameless atomic absorption spectrophotometry under strict quality control. The values observed after adjustment for a specific gravity of 1.016 were distributed log-normally with a geometric mean of 0.65 microgram/l and a geometric standard deviation of 2.47. There was no effect of aging or any effect of smoking on the urinary manganese concentration. The inter-regional difference may be present but not yet conclusive. As no sex difference was observed in a previous study, it may be possible to deduce that the value may possibly stand for the "background" level of both men and women, either smoking or non-smoking, among the general Japanese population. The observed value is discussed in comparison with values reported in the literature. 相似文献

Although the Dirección de General de Protección Civil (DGPC), an agency of the Spanish government, has been responsible for the collection of data and the statistical analysis of fires since 1985, it has not as yet issued any reports. It is true that a couple of studies have been made, but in neither case did they use a standardized methodology but relied simply on the heterogeneous information provided by the fire brigades which cooperated in the studies. At that time Spanish fire brigades did not have special units for professional fire investigation, nor was the information derived from standardized methodologies suited to research purposes. In addition, information was extremely scarce and basic, focussed only on the fire, the use of the building and personal data of the victims. In this context, the project for a Fire Investigation Unit in the Fire Brigade of Málaga (the sixth largest Spanish province in inhabitants) was set up. Although inspired in the methodologies used in the USA and in the UK, the aim was to create a customized methodology for the first scientific investigation of fires in Spain. Our research was conducted in 2007. Using the methodologies of the USA and the UK, our own methodological approach and the Spanish regulations, we drew up a questionnaire with 110 variables arranged into 6 modules. We studied 96 fires out of the 154 emergency fire calls received in 2007, having omitted some emergency calls for various reasons. Our results revealed that it was necessary to generalize the installation of fire extinguishers in residential buildings, to train the general public in the use of these devices, to promote the use of fire and smoke detectors in residential buildings, to encourage the inspection and control of old electric installations and to monitor the new installations, to generalize the implementation of emergency and evacuation plans and to design new systems and materials for the cabinets where hand-held extinguishers are stored. 相似文献

AbstractInequalities relating to ownership of housing have become a major issue de jour in many Western societies. This article examines how the distribution of homeownership in Sweden relates to two factors widely seen as significant to such inequalities, namely parental tenure status and place of birth. We use longitudinal registry data to examine the bearing of these two factors on individual-level tenure progression since the beginning of the 1990s for persons at different stages of their housing careers. We extend existing understandings of Swedish homeownership patterns by demonstrating that inequalities relating to place of birth and parental tenure intersect with one another in ways that substantially advantage certain subgroups while disadvantaging others, and by demonstrating that experiences of entry into homeownership have in recent years been changing in markedly different ways for these different subgroups. Overall, Swedish homeownership inequalities, far from dissipating, appear to be hardening along existing lines. 相似文献

边坡稳定性的关键问题是确定最危险滑动面(潜在最危险滑动面)和边坡的稳定系数。国内外一般是采用先假定边坡滑移模式,然后近似确定最危险滑动面,再求近似的边坡稳定系数的方法来分析边坡的稳定性,但假设的边坡滑移模式难以反映边坡滑移的实际状态。因此本文探索利用遗传算法搜索最危险滑动面,并得到最小稳定系数及对应的最危险滑动面曲线,取得了较好的效果。 相似文献
