Evaluation and analysis on comprehensive utilization of"production-ecological-living spaces"in Zhengzhou City in the past 18 years
Land space is the basic resource for social and economic development and construction of a country or a region,and it is the carrier,foundation and support of human society and economic development.Based on land use in Zhengzhou statistical yearbook data,with the help of ArcGIS,SPSS and other software operating platforms,using the analysis of land use information entropy value method,comprehensive evaluation analysis of land use of Zhengzhou city junior space,space for Zhengzhou city junior provided theoretical basis for the reasonable use and the planning and construction.The results showed that:(1)in 2010,the production space accounted for 70.63%of the total land area in Zhengzhou,followed by the living space and ecological space,accounting for 16.31%and 13.06%respectively.From 2010 to 2017,the area of production space showed a decreasing trend,the proportion of which decreased by 8.13%.The area of living space and ecological space showed an expanding trend,and the proportion of which increased by 2.92%and 5.21%respectively.(2)In the study period,the transfer amount of"production-ecological-living spaces"spatial area was large,with a total area of 2391.06 km2,accounting for 31.65%of the total area of Zhengzhou city.From the perspective of spatial transfer map,the transfer rates of production space to living space and ecological space,living space and ecological space to production space map unit were 11.88%,7.22%,6.70%and 4.26%,respectively.(3)From 2010 to 2017,the comprehensive utilization evaluation index of"production-ecological-living spaces"in Zhengzhou City increased from 0.38 to 0.735,and the production space,living space and ecological space increased from 0.145,0.025 and 0.209 to 0.289,0.17 and 0.39 respectively.It shows that the comprehensive utilization of"production-ecological-living spaces"in Zhengzhou has been optimized and improved,and the intensive degree of comprehensive utilization of"production-ecological-living spaces"space has gradually increased.The research results provide data basis for the rational layout and planning of"production-ecological-living spaces"in Zhengzhou City,so as to improve the land quality of"production-ecological-living spaces"in Zhengzhou City.
