摘　　要：在人口膨胀和快速城市化的全球化背景下,构建人与自然和谐的生态景观是城市景观规划和设计的基本美学观和价值观。缺乏统一的指导原则和评价标准使得城市生态景观建设出现了很多问题,也限制了生态景观的进一步推广和实践。基于文献调研和专家咨询的方式,归纳了城市生态景观的基本内涵和指导原则,并提出了针对性的评价指标。通过问卷调查的方式,获取了170余份有效问卷,据此分析公众对城市生态景观的理解和需求。可以依据该结果为城市生态景观的定量评价提供初步的权重值,为进一步完善生态景观建设的理论和方法提供了参考和依据。The world＇s population is becoming urbanized as people migrate to the cities. It is expected that most urban growth will occur in less developed countries during the next decades. One of the major effects of rapid urban growth is ＂urban sprawl＂ that increases traffic, saps local resources and destroys open space. Urban sprawl is responsible for changes in the physical environment, and the form as well as spatial organization of cities. Urban ecosystems not only provide recreational and aesthetic values, but tangible benefits of clean air and water, conservation and reuse of natural resources, increased biodiversity, and other products that increase the livability of our communities. Creating sustainable urban ecosystems involves optimizing landscape constructions based on considerations that are ecological and social. The main goal of urban planning is to make all amenities and comforts available to the public without imposing many negative effects on society and environment, referred to as ＂ sustainable growth＂. Therefore, urban ecological landscape is drawing wide attention. Developing ecological landscapes will be capable of contributing to the advancement of technological and scientific solutions that can address the grand challenges of urbanization. However, there are lots of problems in existing urban ecological projects owing to lack of uniform guidelines and evaluation indicators of ecological landscapes. Therefore, it is important to build evaluation indicators used to guide urban ecological landscape construction. This paper reviews the progresses of ecological landscape research and summarizes the essential characteristics of urban ecological landscapes.Ecological landscape can be defined as an anthropogenic or managed landscape with deliberate form of human intervention, and with careful protection to improve natural conditions or repair environmentally destructive impacts. Among various features of urban ecological landscapes in related references, three basic merits are summarized in this
