摘    要:由于城市绿地指标(包括绿地率和人均绿地指标)受城市边界的主观性和可变性以及城市中绿地的空间分布的影响而有很大差异,这些指标很难或不足以衡量城市绿化和环境质量。为此,笔者提出以景观可达性作为评价城市绿地系统对市民的服务功能的一个指标。以中山为例,这一指标不但可以完善绿地(或其它服务设施)实际效用的评价体系,同时,为实现以人为本的城市规划思想提供了一个有力的依据。

关 键 词:景观可达性  城市绿地  指标  评价

Abstract:Duo to the flexibility and subjectivity in defining urban boundaries,the commonly used idices for measureing the function of urban green system,such as average green area per capita and overall percentage green area,can hardly reflect the actual efficiency and their actual services for the citizens.The authors propose the use of landscape accessibility as a measurement of the services or function of the green urban system. This measurement can not only play as a complimentary index to the commonly used indices of urban green function (and other services),but also be used to evaluate the impact of landscape change,and the livability of urban environment.Zhongshan City of Guangdong Province is employed as an example. The GIS technology is intensively applied in the study.
Keywords:landscape accessibility  green area  GIS
