摘要
目前城市道路绿地规划评价的指标为绿地率和绿化覆盖率,该指标体系存在一定局限性,需要进一步完善。通过查阅大量文献资料,全面分析了绿地率、绿化覆盖率等指标的不足,从城市绿地空间结构类型、提高城市道路绿量的措施和方法、城市道路绿量定量研究的方法、城市道路绿量与道路其他环境因子的关系、影响绿视率的因素、绿视率与其他绿化评价指标的关系、提高绿视率的措施等方面论述了绿量、绿视率等指标的优点。研究表明,将绿量、绿视率纳入城市道路绿地规划评价指标体系,用绿地率、绿化覆盖率、绿量及绿视率等4个指标综合评价道路绿地,代表着今后发展的方向。
At present,the urban road-greenbelt plan evaluation indexes are green land ratio and afforestation coverage ratio.There are still some deficiencies in this evaluation index system,it is necessary to make further improvement.This paper analyses the deficiencies of green land ratio and afforestation coverage ratio completely by reviewing literatures.Advantages of other indices such as vegetation quantity,and green looking ratio were discussed from the aspects of the space composition types of urban green land,the methods of heightening urban road′s vegetation quantity and its quantitative research ways,the relationship between vegetation quantity and other environmental factors,the influence factors of green looking ratio,and the relationship between green looking ratio and other green evaluation indexes as well as the methods of heightening urban road′s green looking ratio.It was concluded that 4 indices should be adopted in the evaluation system,i.e.,green land ratio,afforestation coverage ratio,vegetation quantity and green looking ratio etc four indexes.
