Abstract：

Analysis on spatial patterns and driving force of green space system, the evaluation of it and its correlation with related policies, could guide better planning for it in the future. London is one of the most successful examples in the world to promote the green belt around the city. Based on ENVI5.3 and GIS platform, this paper deeply explores the green space system of London since 1975 using MSPA (Morphological Spatial Pattern Analysis) from three perspectives: the temporal dimension, its spatial pattern types and their relationship with related policies. It finds that the green space system in London has experienced the development track of “dividing-combining-dividing” since 1975, which can be divided into three development stages: the fragmentation trend from 1975 to 1985, the integration of strip green space from 1985 to 2010, and networking of “point-line-face” green space between 2010 and 2018. On the whole, changes in the spatial patterns of the UK’s green space system are inextricably consistent with relevant policies, with all seven categories of green space patterns have greatly improved in the 21st century. As a dynamic system constantly developing and improving, the UK’s green space system is subject to the driving factors’ influence including construction land and bare land, which causes a phenomenon of “self-organization” development in certain periods. In addition, the protection and construction of “pores” and “edge” should be focused on specially when developing “park city”.
