景观建设正在成为我国城市建设过程中突出的问题。分析了号观、城市景观的概念与特点,回顾了国外城市景观的研究发展和16世纪以来景观建设的历程,认为国外城市景观建设的特点在于以建筑控制法规为中心,注重景观评价的制度化和立法。从规划设计实践、理论研究和专业建设、法规制度建设三个方面对我国城市景观建设的现状问题进行了剖析,最后提出了推进我国景观建设发展的三个构想:确立景观权益的法律地位和推进景观评价的制度化;进一步丰富规划控制手段;整顿行业、建立规范。 相似文献

景观生态学在城市规划和管理中的应用 总被引:53,自引:2,他引:53
城市是典型的人工景观,空间结构上属于紧密汇聚型,功能上表现为高能流、高容量和文化上的多样性。城市景观生态研究包括城市空间结构与生态过程,城市景观风貌与城市生态建设,城市景观规划是其最直接的应用。首先论述了城市景观质量与价值评价,包括景观美学评价与景观视觉容量。城市空间结构和景观规划原则是该文论述的主题,包括城市空间布局、城市空间扩展的廊道效应以及城市绿地系统的空间结构分析;以上海和广州市的绿地系统为例进行了重点介绍,最后对于城乡交错带的景观变化进行分析,用景观格局及其动态来描述城乡交错带的城市化过程特点,介绍了上海和沈阳的典型研究。 相似文献

本文论述嵖岈山国家地质公园花岗岩地貌景观的类型、花岗岩地貌景观特征,对河南遂平嵖岈山花岗岩地貌景观特征与国内外典型花岗岩地貌景观进行了对比分析,嵖岈山花岗岩地貌景观特征:①嵖岈山花岗岩地貌景观主要是花岗岩像形石地貌景观,各种形态的花岗岩像形石有100多个。受中粗粒正长花岗岩矿物成分、结晶程度、球状风化的影响,大多数花岗岩像形石表面圆滑棱角很少,看起来不抽象更形像逼真。②嵖岈山花岗岩体呈岩株产状,分布面积不大,使花岗岩体整体地貌景观精巧典雅看似“天然盆景”。③嵖岈山拔地而起的山与平原接壤的独特地貌地形,让嵖岈山花岗岩地貌景观看起来又非常雄伟壮观。④嵖岈山花岗岩洞穴(石棚)地貌景观众多,洞套洞、洞连洞,洞长达几十米甚至上百米。嵖岈山花岗岩地貌景观美学观赏价值极高,嵖岈山花岗岩地貌景观的美学观赏价值体现在:美、奇、雄、险、幻。认为嵖岈山花岗岩地貌景观的特征是因嵖岈山花岗岩为中粗粒正长花岗岩,矿物颗粒结晶比较粗且岩性较均一、岩体内节理裂隙发育程度疏密适中、独特的地貌部位和北亚热带向暖温带过渡地带的气候条件形成的,是花岗岩地貌显著地带性有力见证。为发现类似的具有美学观赏价值的花岗岩地貌景观提供借鉴。 相似文献

国内外多功能景观研究进展与展望 总被引:12,自引:0,他引:12
作为沟通自然景观与人类社会的重要桥梁,景观功能一直以来都是景观生态学的重要研究内容;多功能景观通过对自然景观功能赋予人类价值评判,与土地利用决策紧密相关,已成为当前景观功能研究的重要发展方向、多学科景观综合研究的重点领域和景观生态学新的学科生长点。在系统梳理多功能景观概念内涵的基础上,对比分析了其与景观多功能性、生态系统服务及多功能农业的概念异同;并从景观多功能性评价、多功能景观空间识别、多功能景观规划与管理等3个方面,重点探讨了近年来国内外多功能景观研究的进展及其主要不足;最后,展望了当前国内外多功能景观研究的重点发展方向,即多功能景观权衡机理解析、多功能景观区域类型识别、多功能景观尺度与划区效应评估、多功能景观动态预测及情景模拟。 相似文献

Geographical analysis, diagnosis and prognosis of landscape centre on regional questions. Within this framework landscape diagnosis helps to evaluate capabilities of or hazards to landscape elements or landscape units, starting from an analysis of the equipment of the landscape and of land use patterns, taking into account tendencies of their development. Landscape diagnosis is connected with landscape prognosis, which characterizes conditions and processes of changes in the landscape and contributes to decision making with regard to landscape development. Examples from the densely populated areas round Halle and Karl-Marx-Stadt and the fruit-growing Havel region around Potsdam will serve to show that small-scaled and medium-scaled landscape diagnoses can be developed as secondary diagnoses mainly on the basis of thematic maps, which can then be used in the offices for regional planning in the GDR. Large-scaled landscape diagnoses, however, will be shown as directly derived from field data and as immediately applicable (as a working basis) to landscape management. The synthetic aspect, which takes into consideration the present state and the development of landscape as a whole, will apply to all scales. 相似文献

This study was taken up to investigate the effects of landscape patterns on the soil erosion processes in a mountain–basin watershed. The revised universal soil loss equation and sediment delivery distribution models were used to estimate the soil erosion processes. The landscape patterns include the landscape metrics at the landscape level, landscape composition and configuration indicators on the basis of source–sink landscape theory. In the study area, the grassland, bare land, farmland and construction land were the sediment-source landscape; the forest and shrub were the sediment-sink landscape. The correlation analysis results showed that the soil erosion processes were significantly associated with the landscape patterns of the study area. At the landscape level, fragmentation metric was positively correlated with soil erosion; diversity metric was negatively related to soil erosion and sediment yield at the sub-basin scale. Among the source–sink landscape composition and configuration indicators, the composition indicator was positively correlated with soil erosion rate and sediment yield. In the configuration landscape indices, the shape index was negatively correlated with soil erosion rate and sediment yield; the fragmentation index was positively correlated with soil erosion rate and negatively correlated with sediment delivery rate. These results indicated that the optimization measures, such as increase in the area, connectivity and regularity of sediment-sink landscape, or decrease in the proportion, connectivity and regularity of sediment-source landscape, were favorable for soil conservation. Furthermore, the landscape indicators based on the source–sink theory could provide more information for landscape pattern optimization to reduce soil erosion. 相似文献

中国园林与西方园林由于思想文化的差异在园林设计语言上形成了不同的风格,这种差异在古典园林中表现得更为明显。在现代园林中,由于国际化进程的加快在园林设计语言风格上的差异日趋减少,不能再用某一固定定义得到完全的划分,取而代之的是设计上个性化、多样化的艺术形式的产生,丰富着园林的设计语言。本文通过对中西古典园林在建筑、水体等方面设计语言运用上的比较,以及现代园林中设计语言多样化的分析,目的在于丰富和深化园林设计语言,创作更加优秀的园林艺术作品。 相似文献
