Green Space System Design in Luoyang Using Huff Model

摘要

Green space system,as part of the urban ecological environment and urban landscape,plays a significant role in the protection of biological diversity of the urban eco-systems.During the process of rapid modernization in China,it is evident that in order to satisfy the residents' needs of entertainment and communication effectively;there should be abundant types and adequate arrangement of green space.And at the same time a comprehensive and stable hierarchical structure of green space system ought to be established.Huff Model is widely used in facility location planning and service area segmentation in business geography,and has potentials in urban facility planning and design.This paper aims to evaluate,design and optimize the urban green space in Luoyang City,Henan Province,using GIS and Huff Model.Considering the existing location,size and shape of the green space supply,the spatial distribution of residence and the urban transportation systems,the attractiveness between residence and green space is estimated.The spatial pattern and service capability of the green space system are also evaluated critically.Based on the findings,the possible optimization design of the green space system in Luoyang is discussed innovatively.Huff model test shows that the design improves the overall spatial accessibility observably.The case study shows that GIS technology and Huff Model have great potential in urban green space evaluation,planning and design.
