厂区围墙外侧绿带景观特征及评价——以安徽省宁国经济技术开发区为例

Landscape Features and Evaluation of Green Belt Outside the Factory Wall——Taking Ningguo Economic and Technological Development Zone,Anhui Province as an Example

近年来,开发区作为新型的产业形态在各地迅速发展。厂区围墙外侧绿带作为企业名片、城市画卷和绿色保障线,对提升园区环境品质和运行效率的作用日益突显。以安徽省宁国经济技术开发区厂区围墙外侧绿带为研究对象,选用层次分析法构建厂区围墙外侧绿带景观评价体系,选取20个典型样地进行景观特征分析及评价。结果表明,20个样地常用绿化植物共计27科36属46种,低矮常绿灌木应用较多,配置形式有规则式、自然式、特殊形式;景观质量整体水平不高,呈正态分布,Ⅰ级(C_(CEI)≥80%)景观质量样地相对较少。针对景观特征及评价结果,提出增加抗污吸毒能力强和观赏性植物的运用、丰富植物配置形式、进行景观提升改造等建议。

In recent years,development zones,as a new type of industry,are blossoming rapidly all over the country.As a business card,city picture and green guarantee line,the green belt outside the factory wall plays an increasingly important role in improving the environmental quality and operation efficiency of the park.Taking the green belt outside the factory wall of the Ningguo Economic and Technological Development Zone,Anhui Province as the research object,the landscape evaluation system of the green belt outside the factory wall was constructed by using the analytic hierarchy process,and 20 typical sample plots were selected for landscape characteristics analysis and evaluation.The results show that there are 46 species of common greening plants belonging to 36 genera and 27 families in 20 sample plots.Low evergreen shrubs are widely used.The configuration forms include regular,natural and special forms.The overall level of landscape quality is not high,showing a normal distribution.There are relatively few sample plots with grade I landscape quality.Based on the landscape characteristics and evaluation results,this article proposes suggestions,such as increasing the use of ornamental plants with strong anti-pollution ability,enriching the plant configuration forms,and improving the landscape.
