Evolution of the"Production-Living-Ecological Spaces"Pattern in Jinzhai County and Analysis of Driving Factors
The pattern and functions of the production-living-ecological(PLE)space in ecological functional areas are transforming due to rapid urbanization.Using land use data of Jinzhai County,Anhui Province in 2009,2014 and 2019,the land spaces were classified,and the landscape pattern index as well as ArcGIS overlay analysis method were used to explore the spatial-temporal evolution characteristics of the PLE pattern and functions in the study area,and the gray correlation model was used to reveal the key driving factors that caused the evolution of the"production-living-ecological space"pattern in the study area.The results show that:(1)The distribution pattern of"production-living-ecological space"in Jinzhai County is different in horizontal and vertical regions.Ecological space is widely distributed,and production space is mainly distributed in flat areas such as the northern and central parts of the land.Living space is scattered in production and ecological space.(2)The transformation of land use structure and function has undergone significant changes,with more active changes from 2014 to 2019.The structural changes mainly include a decrease in production space,an increase in ecological space,and a decrease in fluctuations in living space;The main manifestation of functional transformation is the mutual transformation between production space and ecological space,with an increase in the proportion of living space transferred out.(3)Macro policies,urbanization development,industrial development,and ecological governance are important driving factors for the evolution of the"production-living-ecological space"pattern.
