推进山区工业化必须要有与之相适应的山区城镇建设。但是,从山区城镇建设的现状看,城镇建设明显滞后于工业发展的需要。对推进山区工业化进程有很大的制约。主要表现在以下几个方面:其一,基础设施建设滞后。一方面,受客观因素的影响,长期以来山区的水、电、路、讯明显落后于其他地区。另一方面,受主观原因的影响,在城镇建设中,我们往往囿于传统的观念,对城镇建设在工业发展中的作用缺乏足够的重视。其二,投资环境不尽人意。其三,市场辐射能力弱小。其四,综合服务功能残缺。 因此,推进山区工业化必须重视山区城镇建设。 首先,城镇是山区工业规模化生产的基地。山区工业化一个最基本的特征就是山区资源和农副产品得到 相似文献

现阶段,随着我国经济的不断发展,对于城镇的规划问题也越来越严重。为了使我国在城镇建设的时候,具有更高的竞争力,能够实现我国城镇的可持续发展。城镇规划管理是城镇的发展建设中非常重要的一个环节,对城市进行良好的规划管理,对于城镇的整体建设与发展有着非常强的指导意义。本文基于城镇在规划管理中的现状,对城镇规划管理的实施进行详细的研究探讨。 相似文献

景观生态学是景观学与生态学相结合的边缘学科。它以实现人与自然和谐发展为目标,对人类生存空间的规划、建设、保护和利用等内容进行综合研究。如何将景观生态学的相关理念应用到城镇景观规划设计中,已成为当前城镇规划与景观设计研究的热点之一。景观生态学的基础理念 景观生态学对城镇景观设计的影响具有层次性。首先,表现在城镇区域的宏观层面上。城镇是一个人工镶嵌体。它的建设是一个对城镇区域环境进行改造与利用的过程,因而在城镇规划中,对自然山水的利用有一个是“善待环境”还是“自我表现、唯我独尊”的价值理念的选择问题;第… 相似文献

In the past, river engineering works have often caused channel instability and adversely affected the river's conservation and amenity value. Recent guidelines have advocated a more natural approach to river engineering practice which retains habitat diversity within the river system. While a more natural approach is desirable, geomorphological guidance is required to ensure that the advocated changes are feasible and sustainable, both in the long and short term. The key requirement for sound environmental river engineering is a basic understanding of the natural processes controlling channel shape and dimensions. Examples are given in the paper to illustrate how such knowledge can be used to (a) stabilize rivers, (b) design environmentally-acceptable and stable flood-alleviation schemes, and (c) restore previously canalized rivers. The basis of the geomorphological input in the assessment and design process is a river survey which determines the factors controlling channel characteristics and how it will respond to planned changes. 相似文献

This paper reports the use of geomorphological mapping to obtain a better understanding of the terrain for the Lower Kihansi
Dam Access Road in the Udzungwa Mountains. The long-term accessibility of the road and protection of the natural resources
of the area were pre-conditions for the construction of this road, which was primarily to facilitate the transportation of
equipment, machinery and personnel during construction of a 54,000 m3 concrete gravity dam related to a 180-MW hydropower station. Black and white vertical aerial photographs supplemented with
field mapping were used to prepare a 1 : 5,000 geomorphological map of a possible route corridor. The mapping identified areas
with unfavourable ground conditions which were subsequently studied and characterized in order to select the final route.
In sections where it was not possible to deviate the road from the unfavourable areas, protection and stabilization measures
were considered during the design and construction phases. The road was constructed successfully and without causing damage
to the environment. Geomorphological mapping proved to be a useful tool in selecting the optimum route and appropriate construction
method.

小城镇总体规划“规模—布局—时间”模式研究 总被引:5,自引:1,他引:5
对中国来说,实施“小城镇建设工程”,是真正提高我国城市化水平和社会经济发展的一股“内生”力量,然而传统的小城镇总体规划“规模—布局—时间”线性模式,过分强调时间概念,严重束缚了小城镇的发展。作者分析了传统规划模式特点及其弊端的基础上,探讨了一种“规模—布局—时间”网状模式,在模式中,引入了经济区域、不定性、弹性绿地等概念,以期对于新世纪我国小城镇的规划、发展及提高,起到一定的推动作用。 相似文献

The authors examine processes underlying the growth of small urban areas in England. "There is evidence of 'people-led' growth in environmentally attractive locations (for example, through retirement migration). However, growth of small- and medium-sized towns also reflects employment decentralisation and deconcentration to freestanding or satellite towns, and the extension of commuter hinterlands.... Government policies encouraging growth are also demonstrated to be significant." The processes resulting in population decline in some small towns are identified. "The impact on modelling growth in urban areas of a diversity of causal processes and locational contexts for growth is considered." 相似文献

黑龙江林区中心镇是资源再生型城镇,是我国小城镇中比较特殊的一类群体,它们因资源而生,但也随着资源枯竭与政策调整、发展日趋陷入困境。研究寒地林区中心镇用地布局成为当前刻不容缓的问题。从中心镇大量的用地调查数据入手,调研黑龙江省内的各林业局、林场和与林业相关的建制小城镇。采用统计分析法,对用地进行定性和定量分析。通过对69个县市林业局的统计分析表明:林区中心镇所处的自然条件相似,一般以独立形态存在,规模小,分布广,工业布局分散,以国有林工业为主,土地和空间的集约度相当分散。通过调研,对林区中心镇用地规划提出四点对策建议。 相似文献

From the colonisation of the present Argentine territory by the Spaniards onwards, the foundation of towns and villages implied the effective occupation of the land. Towns were settled along the main commercial routes, while villages appeared in relation with the defence of the frontiers or the exploitation of natural resources. Most urban centres were the result of a pre-existing plan that included an urban layout and a plots system. After independence from Spain, new towns and villages were founded, especially in territories that had not been occupied in colonial times. The regular grid pattern layout introduced by the Spaniards continued to be predominant up to the twentieth century, something that allows us to refer to the typical Argentine urban feature and to its presence in the country's cultural identity. The purpose of this paper is to introduce the evolution of the most typical urban layout over four hundred years, including reference to the present situation of the main Argentine cities. 相似文献
