The research on dynamic changes of urban green spaces in Wuhan at a local scale

Abstract

Urban green spaces play a vital role in urban ecological construction and sustainable development. The primary objective of this paper is to monitor the dynamic changes of urban green spaces in Wuhan city, China from a local perspective. Combined with ArcGIS and Fragstats software, we applied two landscape metrics to detect the change process and change type of urban green spaces during two consecutive periods, 2009-2014 and 2014-2019 at pixel level. The results showed that except for few edge regions, the coverage of urban green spaces declined during 2009-2019. The urban green patches tended to be more fragmented mainly in the central part of Wuhan in the past decade. At the same time, the research results could provide reasonable decision support for the protection of urban green spaces.
