The traditional urban form in historic ningbo has undergone many radical transformations over the past two decades . the relatively homogeneous traditional fabric of the city has been damaged and remodeled following modernized urban models . this paper aims at synthesizing urban renewal and conservation through examining the revitalization of a particular traditional urban area . the case of the west yuehu area of ningbo is selected to show the planning approaches and proposals , constraints and contradictions regarding revitalization under this social transition . the methodology used in the research is divided into two parts : literature review and field study . the theoretical part of the research regarding urban conservation in china is based on literature review . the field study is conducted by the authors and groups of students from southeast university . the complete methodology attempts to illustrate the dimensions of urban renewal by examining the processes , conflicts and results of revitalization of historic urban areas , considering the present changing socio - economic context 在过去20年中,宁波传统历史街区经历了快速转型.新的城市形态取代了传统城市形态,传统城市格局遭到了破坏.本文通过对一些特殊历史街区的分析研究来阐明城市中的保护与更新.以宁波月湖西部地区为例,提出了规划设计的方法,阐述了其中的一些限制性因素及矛盾与冲突,并以此为例来阐述在此大背景下再现城市活力的重要性.文中运用了2种学习方法:一是通过对资料的学习来获取理论来源,二是通过现场调研获取第一手资料.试图通过对传统历史街区在更新过程中的冲突与结果的分析来阐明传统历史街区更新和再现活力的情况
In recent years , the function and construction of the city could not adapt to the possession in our country course of the economics developed rapidly , so the renew and reform of the old area in the city became an important discussion during the growing of the city in our country . this dissertation is based on the present condition and the problem in the old area of our countries , commenced from the city ' s space construction and its appearance , proceed comparison the renewal and the development of the old area space in domestic and international city , and investigate the renewal process of the space construction in the old area of city 近年来，由于我国城市经济的迅速发展，使得城市原有功能结构和物质设施不能适应时代需要，因此城市旧区的更新与改造就成为我国城市发展中所面临的一个重要课题。本文针对我国城市旧区更新的现状和问题，从城市的空间结构及其形态入手，对国内外城市旧区空间结构的更新与发展进行比较，总结出城市旧区空间结构的更新过程。
During the process , the labor legislation gradually improves , the ideas of the labor law continue updating , and the labor law has changed from a private law to a law composed of private attribute and public attribute . the labor law becomes possessing the attributes of the social security law and a part of it . the thesis is divided into three parts in order to probe the proposition that the labor law is a part of the social security 从古今中外各国劳动法立法的完善、劳动法属性的演进和劳动法理念的更新过程中,可以发现:劳动法的立法宗旨最终定位为寻求个人利益和社会利益的协调发展;劳动法律关系的主体、客体和内容兼具“公” 、 “私”属性;劳动合同体现出国家意志和当事人意思自治的完美结合;劳动争议解决的手段也是“公” 、 “私”并用;劳动保障监察更是以保护劳动者利益为目标。
