| Land resources are an important cornerstone of human survival and development.With the development of social economy,the acceleration of urbanization,the expansion of urban and rural construction land,the squeeze of a large number of agricultural and ecological land,the contradiction between urban,agricultural,and ecological space has intensified.Inconsistent contradictions between production and living activities and the internal relationships of natural ecosystems.At present,Jiangxi Province is in a stage of progressive economic development,and the rational use of land resources is particularly important.To this end,it is necessary to continuously improve the level of ecological construction,promote the coordinated development of the city’s "Ecology-production-living" space and coordinated development of the "Ecology-production-living" function,and realize the sustainable development of Jiangxi’s economic.From the perspective of time and space,the spatial functional pattern of"Ecology-production-living" and the intensity of human activities are analyzed to reveal the differentiation between the types of territorial space functions and the intensity of human activities,and help explore more effective land based on the relationship between the two Space function structure optimization adjustment plan.Taking Jiangxi Province as the research area,through data analysis,applying statistical models such as location entropy,Lorentz curve and Gini coefficient,and econometric models in landscape ecology methods,combined with the spatial clustering analysis of Arcgis 10.2 software,revealing the spatial and temporal differentiation characteristics of the spatial function types of"Ecology-production-living" in Jiangxi Province from 2006 to 2017,combined with the differentiation characteristics of the intensity of human activities in Jiangxi Province,to explore the correlation between them,in order to provide a basis for the formulation of land use policies in Jiangxi Province It provides a reference for the optimization of land space and the construction of ecological civilization in areas with rapid urbanization,and promotes the sustainable development of counties and cities in Jiangxi Province.The results show(1)From the perspective of space,it can be seen that the spatial function structure distribution of "Ecology-production-living" in Jiangxi Province is significantly different.The distribution of diversification index shows a decreasing pattern of higher in the north and lower in the south.The spatial differentiation of the concentration index is more significant,the overall dominance is higher,and it shows the spatial pattern of high and low in the middle of both sides of the north and south;spatial function structure Features with low level of uniformity.(2)From the time series,From 2006 to 2017,the distribution pattern of the"Ecology-production-living" spatial function structure showed a disproportionate structure.Among them,the ecological space area is the largest,the production space area is second,and the living space area is the smallest.With the change of time,the ecological space The area of land is decreasing year by year,and the area of living space and production space is increasing year by year.(3)By analyzing the location entropy,Lorentz curve,and Gini coefficient,it can be obtained that the spatial distribution of "Ecology-production-living" space in Jiangxi Province is unbalanced,and it tends to be unbalanced over time.Among them,the location entropy of production and living spaces in counties and cities varies greatly,mainly distributed in urban centers with better economic development;the change range of ecological space is relatively small,and the location entropy is located in the northeast and southern hills of Jiangxi Areas with relatively diverse topography such as mountains.(4)The intensity of human activities in various counties and cities in Jiangxi Province is characterized by an irregular decrease from the middle to the surroundings and from north to south.Its change trend is positively correlated with the diversification index and evenness index,and negatively correlated with the concentration index and dominance index.The greater the intensity of human activities,the more complex the composition of the landscape structure,the greater the diversification index and evenness index,and the smaller the concentration index and dominance index. |
