基于多功能景观服务的城市绿地服务半径研究——以包头市为例

A Multifunctional Landscape Research on Service Radius of City Green Spaces:a Case Study on Baotou City,Inner Mongol ,China

城市绿地是城市"社会-经济-自然"复合生态系统的重要组成部分,城市绿地承担着越来越多的生态、经济和社会功能.本文根据多功能景观服务的概念,以内蒙古包头市建成区为研究区,选取城市绿地提供的缓解热岛效应、休闲休憩和避灾3种景观服务,对城市绿地的服务半径进行研究.结果表明:包头市城市绿地景观服务半径覆盖较好,但仍然有一些城区无法获得城市绿地提供的服务;将多功能景观服务用于研究城市绿地服务半径是一种可行的方法,为评价城市绿地质量提供了一种新的思路.

City green spaces play an important role in ecological and socio-economic functions, which are an important part of the complex ＂ social-economic-natural＂ city system. Based on the concept of multifunctional landscape services, the built-up area of Baotou city was selected to understand service radius of the urban green space. Three landscape services were selected such as heat island effect remission, recreation and relaxation and refuge function for residents. The results showed that：l） the distribution of radius of green landscape service of Baotou City is better, but there are still some areas cannot get the services2）Its feasible to using multifunetional landscape services for the study of radius of urban green space service and evaluating the quality of urban green space.
