探析生態(tài)園林建設與城市可持續(xù)發(fā)展
摘 要:隨著社會和經濟的發(fā)展,城市化已成為人類社會發(fā)展的一個必然趨勢,但由此引發(fā)的一系列環(huán)境問題如:空氣污染、水質惡化、地下水位下降、噪音污染、光化學污染、酸雨現象、城市熱島效應等也隨之顯現出來。我國近年環(huán)境狀況公報提出,全國500多座大中城市大氣質量符合世界衛(wèi)生組織標準的不到1% 。如何利用園林植物的生態(tài)效應為城市可持續(xù)發(fā)展服務是每一個城市規(guī)劃工作者共同面臨的問題。文章分析了生態(tài)園林建設與城市可持續(xù)發(fā)展的關系,發(fā)展現狀與前景,并對其未來可能的發(fā)展方向與思路提出了見解。

Abstract: With the social and economic development, urbanization has become an inevitable trend of development of human society, but it triggered a series of environmental problems such as: air pollution, water quality degradation, falling water tables, noise pollution, photochemical pollution, acid rainThe phenomenon of urban heat island effect also will be apparent. China in recent years State of the Environment, the more than 500 large and medium-sized urban air quality in line with World Health Organization standard of less than 1%. How to use the ecological effect of landscape plants for sustainable urban development is a common problem facing planning workers in each city. This paper analyzes the relationship of the ecological garden construction and sustainable urban development, the development situation and prospects, and its possible future development direction of insights and ideas.
Keywords: ecological garden; urbanization; sustainable development

引 言:生態(tài)平衡失調已經成為城市可持續(xù)發(fā)展的主要限制因子。探尋一條城市可持續(xù)發(fā)展的生態(tài)綠色道路已越來越受到人們的關注,并成為國內外學術界研究的一個熱點。作為城市生態(tài)主體的— 園林更是從此突破了“美”的范疇,進入了生態(tài)園林的新階段。為此,本文指出以下粗淺見識,旨在對生態(tài)園林建設與城市可持續(xù)發(fā)展的思路、現狀和前景進行一些有益的探討。
1 生態(tài)園林概述
生態(tài)園林的科學內涵為:1)依靠科學的配置,建立具備合理的時間結構、空間結構和營養(yǎng)結構的人工植物群落,為人們提供一個賴以生存的生態(tài)良性循環(huán)的生活環(huán)境;2)充分利用綠色植物,將太陽能轉化為化學能,提高太陽能的利用律和生物能的轉化率,調節(jié)小氣候。吸收環(huán)境里的有毒氣體,衰減噪聲,調節(jié)生態(tài)平衡。3)美化景觀,在綠色環(huán)境中提高藝術水平,提高游覽觀賞價值,提
