城市园林绿化是在城市中种花种草、植树造林等,通过栽种植物达到改善城市环境的目的,在提高城市生态水平的同时,也促进了人与自然和谐相处。但由于城市经济发展程度不同,各地城市园林绿化发展呈现出不平衡性,导致城市园林绿化出现了一些问题,制约着城市园林绿化的健康发展。 相似文献

城市化与生态型城市园林绿化若干问题的分析 总被引：1，自引：0，他引：1
城市园林及绿化已提高到从人类生存、生活环境的角度来认识。一些发达国家已将生态学科和环境学科列入城市科学，以推动城市建设和管理从宏观上体现人与自然最大限度的协调与和谐。《中国21世纪议程》把经济、社会、资源与环境视为一个密不可分的以人为中心的复合系统。城市园林绿化作为其中的一个组成部分，正在得到全社会的关注和支持。笔者根据我国著名学者钱学森提出“山水城市”的建设方向和我国不少城市正在实践的“园林城市”、“花园城市”等可持续发展城市建设新理念，对城市化与生态型城市园林绿化的现状与发展作了初步分析。认为改善城市生态环境，保证城市可持续发展是城市园林绿化可持续发展的根本目的。 相似文献

遍览如今的城市建设,可谓是"水泥森林",一栋栋大楼林立,无不是水泥冰冷的身影。虽然我们主张建设绿化生态城市,但由于经济杠杆的原因,我们的绿化空地一直在缩水,我们追求的绿化目标也一直不能实现。同时,随着社会的发展,城市作为物质的积累,文化的结晶,其规模也迅速扩大。相应地出现了空气污染、水体污染、热岛等不利于人们生存的诸多因子。作为以人为本的城市,迫切需要改变这种生态状况。因此,生态城市建设是社会发展到一定阶段的产物,是城市发展的必然,也是一个城市文明程度的标志。本文就目前城市建设的现状,谈谈关于发展城市林业化绿化,促进生态建设提几点看法,以供大家商榷。 相似文献

城市园林绿化是当前城市基础设施建设中的重要组成,高质量的城市园林景观不仅可以绿化城市,同时还能对城市生态系统起到调节作用,从而为城市居民提供更加优质的生活环境。现阶段,各地区城市园林绿化面积随着城市发展而不断增加,部分城市园林绿化过于注重城市园林的观赏性,没有发挥出园林绿化所带来的生态调节功能,使城市园林绿化功能性受到很大影响。本文就当前城市园林发展现状进行分析,探讨城市园林绿化过程中存在的问题,并提出几点改善措施。 相似文献

When planned coherently, urban green spaces have the potential to provide cities with a range of unique ecosystem services that support ecosystem and human health. This paper draws on existing green space planning literature to argue that the integration of community gardens into standardised and previously under-utilised public park landscapes represents an innovative approach to providing ecosystem services. Particular focus is given to the challenges facing green space planning in Perth, Western Australia. At an individual level, community gardens provide a venue for an alternative and more accessible form of physical activity – gardening – and a restorative park environment that is a more attractive destination for neighbourhood walking. At the community level, gardens can facilitate bridging interactions between different social groups, whilst providing opportunities for local residents to participate actively in green space planning processes. Perhaps most importantly, community gardens can provide unique opportunities for environmental education that lead to enhanced local ecological outcomes. The paper concludes with a brief overview of the main challenges likely to be faced with this integration, and some strategies that may allow them to be overcome. It is hoped this paper will provide a background for future case studies, and a catalyst for increasing integration between formal green space planning and community garden development. 相似文献

随着科技的进步,人们对生活的条件和质量有了更高的要求。可持续发展、生态等关键词越来越深入人心。现在的发展已经抛弃了原来的只要经济不要环境的发展观。城市里高楼林立,车行如梭,烟尘弥漫,工作节奏很快,缺乏自然美,易使人产生压抑感、疲劳感,缺乏宁静感。美好的园林景色,不仅能满足人们的观赏需求,其改善环境质量的功能是不容置疑的。种植园林树木是防治污染、保护环境的重要措施,树木在调节气候、净化空气、保护环境方面有着重要的作用。 相似文献

Sky gardens have been actively studied and installed in different cities. Their development potential in compact developing cities has received little attention. Using remote sensing and GIS techniques, this study evaluates the vegetation configuration and development potential of sky gardens in urban Hong Kong, their underlying location, land use and building factors, and future planning and implementation concerns. Existing sky garden area is limited with sparse vegetation cover and low biomass. Existing podium gardens exceed roof gardens by about nine times. District development age has little effect on existing and potential sky gardens. Old towns have higher potential roof and podium gardens than new towns in most land uses. The effect of land use on potential sky gardens varies greatly by districts. Buildings with 10–20 floors have higher potential roof gardens in most districts. Building area is the main determinant of potential roof garden, and population density of potential podium gardens. Three scenarios of realization, namely minimum (20%), medium (50%) and maximum (80%), are adopted to project sky garden provision in individual districts. The projection extends to the contribution of new sky gardens to urban greening in terms of green cover and greening rate in districts. The challenges include susceptibility to typhoon damage in high-rise exposed sites, aggressive weed invasion, lack of roof-slab loading data in old buildings, and poor building maintenance. The opportunities include affordability of the new technology, enabling government policy, and establishment of scientific and research foundation in the local context. The development strategy could aim squarely at stringent technical standards and contractor skill requirement, and programme prioritization based on research findings. The study provides useful hints, approaches and recommendations for a systematic sky-garden action plan in Hong Kong and other similar compact cities. 相似文献

Global patterns in urban green space are strongly linked to human development and population density
Urban green space is important for alleviating high temperatures, pollution, and flooding in cities. Furthermore, it is becoming increasingly clear that urban green space is important for the mental and physical health of humans residing in cities and that urban green space may harbor unique biodiversity. Understanding the extent and drivers of urban green space is thus important. While urban green space has been mapped and studied at local to national scales, the global patterns and drivers of urban green space remain unknown, potentially hampering effective planning and allocation of resources toward reaching sustainable development goals. Here, we quantified the effect of environmental and socio-economic drivers (temperature, precipitation, human development, and population density) on urban green space globally by focusing on national capital cities. We used satellite imagery to map urban green space using two measures: the Normalized Difference Vegetation Index (NDVI), and the fractional cover of “green” land cover classes. NDVI is useful as it includes all vegetated surfaces, also small ones like gardens. However, land cover classes allow the exclusion of certain classes such as sports fields or cropland. We used boosted regression trees to show that climatic variables accounted for 75 % of the relative influence in urban green space, with a positive effect of precipitation and a negative effect of temperature. Importantly, socioeconomic variables accounted for 25 % of the influence on global urban green space, with a positive effect of human development index (HDI) and a negative effect of population density. HDI in relation to urban green space has not previously been tested globally, and our study shows that significantly affects urban greenspace. The results demonstrate that cities where development status is low and population densities are high, typically in the Global South, have less urban green space than the climate would predict. The results therefore suggest that human wellbeing does not only benefit directly from increasing human development and decreasing population densities in urban areas, but that these effects may be compounded by also improving nature’s contribution to people. 相似文献

Green Space System Planning (GSSP), taking all the green space within the city administrative area as a complete and comprehensive system, is a kind of official statutory planning that the Chinese government requires all the cities to draw up as a supplement for cities' Master Planning. It is the primary legal basis for green space protection and construction. Its temporal scale is 5 ∼ 20 years, and the planning area is gradually expanding from the urban area to the city area. With China's increasing emphasis on the ecological environment, green space development has been injected with more ecological functions. Simultaneously, the requirements for green space are added to the policy documents issued by several administrations about urban and rural planning. As a result, the qualitative and quantitative requirements for GSSP have become more complex than ever before. This article reviews and summarizes the laws, regulations, policy documents, and standards (national and industrial level) related to GSSP in the urban and rural planning field from the perspective of government requirements. The results show that the Chinese government's requirements for GSSP can be divided into three levels: mandatory, ecological, and promotional level. Furthermore, transforming the three-level requirements to their corresponding aims, this article constructed a hierarchical, multi-objective Aims-Indicators-Methods (AIM) framework of GSSP based on various aims and requirements. We hope that the AIM framework of GSSP can be more practical, which means regions can select an appropriate AIM framework according to their own environmental and economic conditions and simplify the preparation of GSSP. 相似文献
