城中村街巷空间绿视率分析与优化研究

Analysis and Optimization of Green Vision Rate in Street and LaneSpace of Urban Villages

绿视率作为人们对空间绿量的直观反映,也反映了道路与绿化的比例关系,所以绿视率和绿视率满意度能够以简洁的数据和评分反映街巷空间的绿化质量。以墨江县城中村街巷空间为例,采用现状调研、绿视率图像收集及计算、加上线下及网络问卷调查街巷空间满意度的方法进行研究,结果表明:(1)街巷空间平均绿视率均低于35%,居民满意度大部分评价为一般,现状景观质量较差,亟待提高。(2)经过对街巷空间绿视率及其满意度的深入评估,所得到的评价等级标准显示,在景观品质不佳的地区,公众对于绿视率的标准设定更高。(3)针对低绿视率现状提出空间优化、增加绿化、后期植物管理等优化策略,促进城中村人居环境的良好发展。

Green visual ratio,as an intuitive reflection of people's space green quantity,also reflects the proportional relationship between roads and greening,so green visual ratio and green visual ratio satisfaction can reflect the greening quality of street space with concise data and scores.Taking a space of streets and lanes in an urban village in Mojiang county as an example,methods such as current situation investigation,collection and calculation of green view rate images,and online and offline surveys are used to investigate the satisfaction of street and alley space.The results show that:①The average green view rate of street and alley space is below 35%,and the satisfaction of residents is mostly average.The current landscape quality is poor and urgently needs to be improved.②After an in-depth evaluation of the green visibility rate and its satisfaction with street and alley spaces,the evaluation level standards obtained show that in areas with poor landscape quality,the public sets higher standards for green visibility rate.③Optimization strategies are proposed such as spatial optimization,increased greening,and later plant management to address the current low green visibility situation,in order to promote the good development of the living environment in urban villages.
