A Study on Distribution of Production, Living and Ecological Space in Karst Areas Based on Lorenz Curves and Land Use Transitions
was studied to provide theoretical guidance for the sustainable development
county-level land planning
and conservation of environment in karst areas.[Methods] Lorenz curves
Gini coefficients
and transition models were used for the comprehensive study of the production
living and ecological space in Duyun City from 2009 to 2018.[Results] ① In 2018
ecological space constituted 69.19% of the total area
followed by production space
which accounted for 26.87% of the total
and living space accounting for the smallest percentage
which accounted for 3.94%. ② From 2009 to 2018
the areas of production space and the ecological space showed a downward trend
whereas that of living space showed an upward trend. In terms of secondary space transfer
the increased areas of urban and rural living space came from agricultural production space and forest ecological space
and urban development occupied a part of forest land resources and agricultural resources. ③ In terms of Lorenz curves and Gini coefficients from 2008 to 2019
ecological space and production space were evenly distributed. Whereas
compared with the other two types
the curve of living space diverted farther away from the line of perfect equality
showing a concave curve. Gini coefficients from 2009 to 2018 were between 0.3 and 0.4
and the distribution of living space was basically reasonable. ④ From the perspective of location entropy
areas with an advantage of ecological space were mainly concentrated in the western part of the study area
areas with an advantage of living space were mainly concentrated in the central part of the study area
and areas with an advantage of production space were mainly concentrated in the southern and eastern part of the study area.[Conclusion] The three types of space were appropriately distributed in Duyun City
with ecological space as the dominant type. Future urban construction should be premised on the preservation of ecological space
with planning for urban development while limiting the use of ecological land.
