Abstract
Based on GIS technology,the main urban area of Chongqing is selected as the research objective to study the characteristics and evolution of blue-green space in this area,and effective urban blue-green space planning suggestions are proposed based on the analysis results.Based on the spatial characteristics analysis of the central urban area,from 2005 to 2020,urbanization led to a sharp decrease in farmland area,with some blue-green land covered by buildings.Based on the analysis of regional spatial distribution,the current green space area of Banan District is 907.65km2,which is superior to other regions.At the same time,research has been conducted on the evolution of regional space.In the past 15 years,there has been a significant increase in urban construction land,which has had an impact on the blue-green space in the region.However,the blue-green space has increased since 2010.In the future,the region needs to strengthen the protection and development of blue and green spaces,in order to provide technical references for urban planning and development.关键词
