应用心理物理学方法对浙江省乡村绿地进行景观美学质量评价研究,分析不同人群对绿地景观的审美偏好、绿地景观美学质量的主要相关因子及其作用特性,构建评价模型。研究结果显示:1)不同群体的审美偏好总体上具有一致性,但对乡土化、城市化程度不同的具体景观存在差异;2)相应地,乡村绿地美学质量评价指标集,包含因评判群体而异和无异2类指标,前者可用以揭示审美主体的态度偏好差异,后者用以分析公众普遍审美情趣,构建评价模型;3)模型选出的关键因子为群落密度、绿地年龄、环境色彩对比度、群落色彩数量和绿视率5个。

包头市城市森林绿地树种选择及效果评价 总被引:6,自引:0,他引:6
以包头市东河区、青山区、昆都仑区、九原区、开发区等五个城区中公园、行道、游园、小区、厂区、防护带等景观类型中树种和群落为调查对象,利用植物物种数、丰富度、多样性指数、重要值等指标对包头市城市绿地植物群落进行调查,用层次分析法评价,对包头市城市绿化树种现状进行分析。针对出现的问题提出在今后城市绿化树种增加种类增加层片和季相,提高绿化的稳定性及不同时间的观赏要求,加大对乡土树种的开发和应用,提高适应性,以减少经济造价。

城市生态环境污染是当前人类面临的日益严重和亟待解决的环境危机之一,它不仅严重危害人类健康,而且已成为人类社会可持续发展的主要障碍,受到世界各国普遍关注和重视。城市的绿化植被作为城市生态系统中的还原组织,已被世界各国的城市发展实践证实其在城市中的价值不可忽视,且受到社会的普遍关注。文章阐述了城市植被对城市大气污染、城市水污染、城市土壤污染以及城市噪音污染等环境污染的植物修复作用。 相似文献

为了创造良好的老年人户外空间活动场所,了解老年人对街旁绿地的使用情况,选取保定市5处街旁绿地——农大园、乐凯园、百花园、茗畅园和同心广场,采用问卷法和量表法,对街旁绿地中老年人的基本情况、游憩情况及其对景观的总体评价进行调查,分析老年人对街旁绿地的使用状况,探求街旁绿地中老年人群的特点及需求,结果发现存在街旁绿地较少、空间组织较为单一、健身和娱乐设施缺乏、交通工具存放和管理较差等问题,提出针对不同的活动内容进行相应的空间组织、完善健身和娱乐设施、完善停车场设施等建议。 相似文献

Status of urban vegetation in Guangzhou City 总被引:11,自引:0,他引:11
GUANDong-sheng CHENYu-juan 《林业研究》2003,14(3):249-252
According to a survey for the urban vegetation of Guangzhou, urban vegetation has a significantly difference from natural vegetation because of intense human impacts. The research was conducted in a synthetic survey for soil, species diversity, roadside trees and ecological function of urban vegetation in Guangzhou City. The results showed that: (1) soil densities of urban roadside and park forests were higher than mean density of natural forest soil. The pH values of soil in urban roadside were higher too, and the content of organic matter and the concentration of nitrogen were lower. (2) Species diversity of urban vegetation was lower. The most number of species was only 16 species in tree layers of urban forest. (3) Tree growth was limited by narrow space in high-density urban area, where the trees with defects and disorders were common. (4) Comparing with mature natural forests, the productivity of urban vegetation was lower. The effect of urban vegetation on balance of carbon and oxygen were influenced by the low primary production of urban vegetation. Therefore, the growth condition for urban vegetation should be improved. Biodiversity, primary production and ecological function should be increased for urban vecletation in order to improve urban eco-environment. 相似文献

Visualization and landscape laboratories in planning, design and management of urban woodlands 总被引:2,自引:0,他引:2
Liisa Tyrvinen Roland Gustavsson Cecil Konijnendijk sa Ode 《Forest Policy and Economics》2006,8(8):811-823
Although participatory approaches are increasingly used in planning and management of urban woodlands, efficient tools are also needed to make the processes work. In urban forest planning impacts of proposed management regimes on aesthetic and recreational values are among the factors that interest the local residents the most. This article explores two potential methods for improving collaborative urban forest planning and design in Europe, based primarily on experience gained in the Nordic countries. The methods relate to the use of (i) computer-based visualization methods and (ii) demonstration forests and landscape laboratories. We suggest that use of both methods may lead to a major enhancement in forest planning and design. 相似文献
