【摘要】 城市作为人类文明的标志和社会经济发展的载体，是人口、产业、资金、生产力和科学技术高度集中的地域，是区域经济活动的核心，同时也是各种矛盾的焦点。城市社会和经济的发展给城市带来人口快速增长、住房紧张、交通阻塞、生态环境污染、耕地以及其它不可再生资源的急剧减少等问题，城市生态系统面临着巨大压力和严峻的挑战，建立可持续发展的人与自然关系和谐相处的园林生态城市成为人们的必然追求和选择。 论文主要包括相关原理和应用案例二个部分。 在相关原理部分首先对前人关于城市建设学说和模式的主要研究成果进行了综述。继而讨论了园林生态城市的特点，建设园林生态城市的理论基础和基本原则；论述了创建园林生态城市的理论与实践意义。认为园林生态城市是以园林生态学和可持续发展为理论基础，在生态城市的基础上进一步发展的更高阶段的城市模式。 从国内外生态城市建设的现实和经验出发，论文认为园林生态城市不仅仅指城市生态系统要有相对稳定的生态平衡和良性的物质循环，而且要有深刻的文化和艺术内涵；园林生态城市的建设应该对提高民众的素质和生活质量，对加强物质文明和精神文明建设发挥积极的作用。 基于对园林生态城市的概念、内涵和相关基础理论的探讨，本文提出在城市建设进程中需要转变单纯发展经济的观念，树立科学发展观，积极开展环境保护和生态建设；在城市发展经济的同时，必须兼顾社会、经济、生态三个效益的协调和可持续发展。 在应用案例部分，本文以安宁市为例，在概括介绍该市近期发展历史和现状的基础上，应用有关理论和国内外经验，分析了安宁建设园林生态城市的优势和薄弱环节，利用遥感技术对生态环境建设进行适时监测和评价，并在此基础上提出包括对城市绿地系统的科学规划、通过对工业污染和水土流失的合理控制实现点面源污染的综合治理等兼具理论性和可操作性的园林生态城市发展途径、建设标准和调控对策。 基于对安宁市自然、社会和经济发展状况和生态环境现状的讨论分析，本文指出安宁生态环境建设中存在的主要问题是工业发展导致环境污染加重；能源问题和矿产资源的开发导致森林生态环境的破坏；城市布局不够合理，缺乏科学、统一的城市规划。 针对安宁是一个以钢铁工业、磷化工和盐化工为主导产业的工业城市，提出要建设园林生态城市和环境友好的节约型社会，重点要对安宁市的磷肥工业、钢铁工业和其它工矿企业进行点源污染控制，对这些厂矿的污染物排放必须通过环境工程辅以生态建设的手段进行综合治理。根据对安宁市水土流失与农业面源污染来源特征的现状调查，提出安宁市控制水土流失和治理面源污染的对策。 通过对园林生态城市建设的相关理论和应用案例研究，本文主要开展了以下工作： (1)从国内外生态城市建设的现实和经验出发，提出了园林生态城市的概念和内涵，认为园林生态城市是生态城市的更高级阶段。 (2)针对园林生态城市的内涵，提出建设园林生态城市的理论基础主要是美学原理、景观学原理、生态学原理和可持续发展理论。更多还原

【Abstract】 As loading media of civilization of human beings, social and economic development, cities are highly concentrated areas of population, industries, capital, productivity, science and technology. In consequence, cities are both the core area of regional economic activities and focus areas with varied problems and contradictions. Social and economic development in urban areas have brought about many of the problems such as explosive increase of population, housing shortage, traffic congestion, environmental pollution and sharp reduction of cropland and other non-renewable resources. Immense pressures and critical challenges are being faced by all urban ecosystems in the world, and building of sustainable, landscaping ecological cities where man and the nature coexist harmoniously has become the inevitable choice and inexorable pursuit.The dissertation is basically composed of two sections, i.e., corresponding principles related to landscaping ecological cities and a case study on application of these principles.Firstly, the relevant theories and models proposed and achievements of the related studies by former researchers were summarized in the first section. Secondly, the characteristics of landscaping ecological cities, the theoretical bases and fundamental principles for building landscaping ecological cities were discussed, and the theoretical and practical significance of building landscaping ecological cities in China were elaborated. It was believed that the landscaping ecological cities should be further developed and superior models of ecological cities, taking theories of landscape ecology and sustainable development as the theoretical foundations.Proceeding from the realities and successful experiences of both domestic and abroad in building the ecological cities, it was believed in that building of landscaping ecological cities should take considerations not only to the ecological balance and healthy cycling of the urban ecosystem, but also to creating profound culture and artistic intension; building landscaping ecological cities ought to play a very important and active role in promoting comprehensive更多还原
