长期以来,中国农村小城镇的无序发展导致了大量小城镇病的产生,制约了我国农村城镇化的可持续发展。通过制定合理的政策措施,并与市场手段相结合,以区域为单元,对农村小城镇在空间结构、规模结构、产业结构、土地利用、基础设施等方面实施综合整理,是实现农村城镇化可持续发展的战略选择。  相似文献

一、小城镇的发展及主要环境问题小城镇是社会经济发展的必然产物,随着社会分工的不断演化使越来越多的人转向非农业,并在某一地区集居逐渐形成小城镇。目前我国小城镇主要有县(区)属建制镇、乡级镇及村镇三种类型。随着农村经济改革的不断深入,乡镇工业  相似文献

农村产业结构变化-农村剩余劳动力转移-农村小城镇发展这一链式反应是改革开放后农村社会经济发展和农村城乡一体化发展的新模式,然而对欠发达地区而言,这一链式反应存在着许多障碍因素,研究表明,在甘肃省酒泉市域,农村产业结构和农村劳动力结构同向转化,但二者存在着明显的相位差,在实现产业结构转化的同时并没有促成劳动力在空间上聚集,致使小城镇发展普遍不足,城乡一体化受阻,为了实现这一链式反应,必须加大乡镇企业的规模化经营,改革现有户籍制度,加强现有城镇基础设施建设,走内涵与外延相结合的发展道路。  相似文献

农村城镇化是我国城市化进程中的重要环节,同时也是小城镇建设的主要目标,对发展社会经济具有重要的意义。从我国现阶段城市化进程的特点、农村城镇化主要形式和存在的问题入手,结合景观生态学的原理,在农村城镇化研究的基础上引入景观生态学思想和方法,分析农村城镇化形成发展的生态过程与空间格局的内在联系,为小城镇建设提供一种新的思路和方法。  相似文献

近年来,许多地区在推进城镇化特别是新型城镇化过程中充分重视发挥信息化的效益。而信息化的同步发展,又促进了新型城镇化以节能、环保和经济可持续方式的发展。如河北、江苏、浙江、福建、吉林和四川等地,重视农村信息化发展,积极支持、引导和推进农村电子商务,通过电子商务应用改变农民传统的社会身份,提高经济收入和农民的组织化水平,促进农村和小城镇经济和产业结构优化,推进农民返村创  相似文献

发展小城镇是目前大力推进中国农村城镇化的一个核心战略.但在小城镇发展的过程中,存在着点多面广,遍地开花,缺乏重点规划等众多问题,从而造成比"城市病"危害性更大的"农村病".本文认为各地区应根据自身特点大力发展重点小城镇,以点带面,实行梯度开发战略.同时,以欠发达地区安徽省庐江县为例,构建了重点小城镇综合能力评价体系,并运用因子分析法、层次分析法(AHP)对庐江县小城镇进行综合能力评价,确定重点小城镇及其发展模式.  相似文献

我国农村城镇化的制度创新   总被引:1,自引:0,他引:1  
一、引言农村城镇化过程就是农村人口、资金、技术、土地等各种生产要素向城镇的空间聚集和使用方向的转变,农业人口比重下降,工业、服务业人口比重上升,生产方式、交换方式和生活方式向规模化、集约化、市场化和社会化发展。因此,要提高农村城镇化的水平,就必须强化产业结构聚集效应,设法使农村区域的产业,尤其是二、三产业发展聚集起来,更好地分工合作和获取信息,建立配套服务业,最终形成农村区域内的中小城镇,推动农村城镇化。所谓产业聚集效应是指以基础产业为支撑面,主导产业为龙头,主导产业、基础产业和一般产业有机结合形成新的经济…  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that  相似文献
