【摘要】 中国自1978年改革开放以来，随着城市化的迅速推进以及大城市的不断扩张，导致了城市生态环境系统的明显退化，产生了一系列的城市生态环境问题。主要表现在空气污染、噪音污染、交通拥挤、用地用水短缺、城市垃圾堆积如山等等方面，这些环境问题已成为我国各城市关注的焦点，有专家指出：“环境问题处理不好，将成为威胁中国社会协调发展的一颗定时炸弹”。因此，如何较好地解决城市化发展与城市生态环境的冲突，是我国学术界值得探讨的重点难点课题，也是我国各城市普遍面临的实际问题。 珠三角凭藉其地缘、人缘、政策的优势，经过二十多年的不懈努力，社会经济实现了超常规的发展，成为中国社会经济发展最快、城市化水平最高的地区之一。然而，珠三角在经济建设取得辉煌成果，令全世界瞩目的同时，生态问题凸现，环境污染问题逐渐暴露，这些问题已成为珠三角社会经济发展的一个制约因素，要解决好历史遗留的环境问题和控制发展过程中出现的环境问题，仍然是一项长期而艰巨的任务。 为此，本文首先回顾了生态恢复与恢复生态学的发展历程、理论基础、研究现状和研究发展趋势；其次全面系统地分析了珠三角区域概况和植物景观现状；在此基础之上，对珠三角城市植物景观恢复技术与质量评价体系进行了深入研究，取得了如下主要成果： 1．丰富了城市植物景观理论 提出了要用植物的标识功能作为城市植物景观建设的一个重要原则和指标。植物标识功能是一个崭新的概念，它极大地丰富了城市植物景观理论。 在总结前人研究成果的基础上，深入分析了景观、城市景观、城市植物景观、景观压力、景观尺度等概念，提出了营造城市植物景观的新原理和新技术。 2．分析了珠三角城市植物景观现状 珠三角城市植物景观主要表现为：植物种类偏少，植物景观结构简单，生物多样性降低，灌草丛比重较大，景观质量不高，这些因素引起了城市植物景观质量和生态服务功能有所下降，出现了比较明显的退化状况。 在研究珠三角城市植物景观退化的原因、过程、机理、类型以及景观特征的基础上，提出了解决城市植物景观退化的途径——营造以乡土植物为主体的城市植物景观系统。 3．划分了城市植物景观类型 在全面分析城市植物景观特征的基础上，结合珠三角的实际情况，把城市植更多还原

【Abstract】 With the modernization and exploitation of big cities, obvious degradation of city ecosystem and series of environmental problems occurred since reform and opening up of China in 1978. These problems include air pollution, noise pollution, traffic jam, short of soil and water, deposits of garbage etc. These problems have been the focus of city attention and the expert pointes out that if environmental problem was not handled well, it will be a time bomb of Harmonious Society in China. Therefore, resolving the contradiction of development of cities and city ecosystem is the key project to explore in Chinese science society, also it is a practical problem facing up to every city in China.Through more than 20 years endeavor, Zhujiang River Delta depended on the advantages of geographical features, personality and policies, and society and economy developed super normally, then the Delta became into the area which is the fastest area in economic development and the highest area in city modernization in China. However, environmental and pollution problems of Zhujiang River Delta have been a restricted factor to the social and economical development of the Delta. To resolve the historical environmental problems and the environmental problems in the process of regulating the development is still a long-term and arduous task.Therefore, this paper looked back the Eco-Restoration and the developmental process, theoretical basic, research situation and research tendency of restoration ecology firstly. Secondly, general situation and plant landscape situation of Zhujiang River Delta were analyzed comprehensively. On the base of this situation restoration methods and evaluation system of Zhujiang River Delta were studied deeply and the following are the major achievements:1. Richness of the theory of city plant landscapeIdentification function of plants was regarded as an important rule and index of the construction of city plant landscape at the first time. Identification function of plants is a fire-new conception and it enriches the theory of city plant landscape infinitely.On the base of previous research results, conceptions of landscape, city landscape, city plant landscape, landscape pressure and landscape scale were analyzed deeply, and new principle and new technique to construct city plant landscape were presented.2. Analysis of the status of city plant landscape in Zhujiang River DeltaThe main representations of city plant landscape in Zhujiang River Delta are few更多还原
