廊道网络指数评价方法在绿地系统规划中的应用

由于城市绿地指标（绿地率和人均绿地指标等）受城市边界的主观性和可变性以及城市中绿地空间分布的影响而有重大差异，这些指标不足以衡量城市绿地的环境质量和生态功能。在绿地系统规划中，规划人员往往根据主观意见、服务半径分析等简单方法确定现状城市绿地分布存在的问题，缺乏对城市绿地生态服务功能的研究。规划研究缺乏数理研究方法的支撑，缺乏理性判断依据。为此，笔者提出利用景观生态学廊道网络指数作为衡量城市绿地系统功能的评价方法，该方法在规划前期研究和方案对比工作中特点突出，增强了规划方案的针对性和科学性。

Application of Gallery Network Index Evaluation Method in Green Space System Planning

There are many materially differences between the index of the urban green space, because the urban green space is influenced by the subjectivity and variability of city boundaries. These indicators are not enough to measure the quality of the environment and ecological functions of urban green space. During Green space system planning, planners often determine the current situation of urban green space distribution problems through the studying of service radius, or subjective views. Such simple methods are lack of ecological service function of urban green space. Planning studies lack the support of mathematical research methods and rational judgment. To this end, we propose the use of landscape ecology corridor network index as a measure of the function of urban green space system evaluation method, the prominent feature of the method in contrast the work of the pre-planning research and programs greatly enhanced planning program for and scientific.
