【摘要】：城市的空气质量问题直接关系到城市的经济发展和生态环境建设,也影响着城市在国内外竞争中的地位。近几年,我国各省市政府对各个城市的空气质量的改善也越来越重视。众所周知,绿色植物能够通过自身的光合作用等吸收染污气体,净化空气,基于此本文主要对园艺景观绿色植物对空气净化的作用进行分析和预测,通过搜集国内外关于园艺景观绿色植物空气净化方面的研究资料,以浙江省的11个城市的空气质量为研究对象,分析园艺景观的空气净化作用。文章首先在绪论对研究背景、研究的意义、国内外的研究综述以及主要的研究内容及路线进行分析,为本文的研究奠定了一定的理论研究基础。然后主要选择浙江省的11个城市的园艺景观以及对应的空气质量作为本文的研究对象。对浙江省的气候情况以及植被状况进行分析。并且对本文采用的三种研究方法:野外调查法、CITYGREEN模型以及层次分析法进行阐述。接着重点使用上述的三个方法,对浙江省的园艺景观的空气净化作用进行评价和预测。使用层次分析法确定评价指标体系模型、并构建判断矩阵、计算权重及一致性检验、对指标进行无量纲化以及确定空气净化作用的评价标准。然后根据确定的指标体系,对浙江省园艺景观绿色植物的空气净化作用进行分析和研究。首先对浙江省的园艺景观绿色植物的调查对象的选择、园艺景观的具体分布情况等进行阐述,然后具体结合第三章的模型对园艺景观植被结构对空气净化作用以及不同城市的园艺景观对空气净化作用的影响进行分析。最后,通过前文的研究提出提高空气质量的方法和策略。
[Abstract]:The problem of urban air quality is directly related to the economic development and ecological environment construction of the city, and also affects the position of the city in the competition at home and abroad. The provincial and municipal governments in China are also paying more and more attention to the improvement of air quality in various cities. As we all know, green plants can absorb polluted gases and purify the air through their own photosynthesis. Based on this, this paper mainly analyzes and predicts the effect of green plants on air purification in horticultural landscape, and collects the research data on air purification of green plants in horticultural landscape at home and abroad. Taking the air quality of 11 cities in Zhejiang Province as the research object, the paper analyzes the effect of air purification on horticultural landscape. The domestic and foreign research review, the main research content and route analysis, Then the horticultural landscape and the corresponding air quality of 11 cities in Zhejiang Province were selected as the research objects. The climate and vegetation of Zhejiang Province were studied. The situation is analyzed, and the three research methods used in this paper are described: the CITYGREEN model and the analytic hierarchy process. This paper evaluates and predicts the effect of air purification on horticultural landscape in Zhejiang Province, uses analytic hierarchy process (AHP) to determine the evaluation index system model, and constructs a judgment matrix to calculate the weight and consistency test. Dimensionless indicators and criteria for determining air purification. Then, according to the established indicator system, This paper analyzes and studies the air purification function of green plants in horticultural landscape in Zhejiang Province. Firstly, the selection of investigation objects and the distribution of green plants in horticultural landscape in Zhejiang Province are expounded. Then the effects of vegetation structure on air purification and the effects of horticultural landscape on air purification in different cities are analyzed with the model of Chapter 3. The methods and strategies of improving air quality are put forward through the previous study.
