Land Use Optimization Based On Theperspective Of Land Use And Regional Economic Coordination

Land is the material basis for human survival,and land use change has always been a research hotspot.There is an inseparable relationship between land use and regional economic development.From the relationship between regional economic development and land use,the coupling degree of the two is discussed to provide guidance for the sustainable use of land and the sustainable development of regional economy.opinion.This paper takes Xishui County in the Karst Mountain Area as the research object,and uses the theory of system theory,sustainable development theory,coordination degree theory and landscape ecology as the guide.Based on the collection of Xishui County economic data and land database,the use of mathematical statistics,Landscape analysis,entropy method,coordination degree evaluation and four-quadrant methods,pointed out the problems and characteristics of land use in Xishui County,calculated the regional economic and land use coordination degree of Xishui County,and used the four quadrant method based on the coordination result.Land use is divided,and different optimization conditions are set for different zones.The following conclusions are drawn:1.Problems and characteristics of land resources in Xishui County: The distribution of land resources in Xishui County is quite different,resulting in different levels of social and economic development in each township.The agricultural land resources are abundant,but the distribution is uneven.The forest areas of the towns and towns where the nature reserves and heritage sites are located are large.The large cultivated land area is mainly located in the towns and villages with relatively flat terrain in the south and west of Xishui County.Due to the influence of the terrain of the karst mountains,Cultivated land is broken.The overall level of land use in Xishui County is not high.The land use structure is not reasonable enough.There are obvious differences in the land landscape index of each township.The diversity index is 0.643 in Huilong Town and 0.386 in Sanchahe Township.The land use diversity is low,which will lead to ecological imbalance.Chengzhai Township and Tongji The highest degree of advantage in the town is 1.834,the lowest is 1.314 in Xijiu Town;the highest uniformity is 0.488 in Xijiu Town and the lowest is 0.275 in Sanchahe Township.In the land use transfer,the construction land mainly comes from cultivated land,grassland and forest land.The large amount of land transfer is the townships and towns surrounding the towns and industrial parks in Xishui County,which leads to partial land degradation and great pressure on land use ecological carrying capacity.2.Using the four-quadrant method to partition the land based on the results of coordination: constructing the evaluation index system of land ecosystem and regional economic coordination degree,and calculating the coupling coordination degree results of each township by means of the coupling coordination degree model.The results show that each township land ecosystem The degree of coupling with the regional economy is at a high value,indicating that the two are closely related in the process of social development.The coordination level mainly includes three types: reconciliation,near-disorder and mild dislocation.The main types of economic-land coordination are: reluctantly coordinating the eco-environmental lag,reluctantly coordinating the regional economic lag,on the verge of dysfunctional ecological environment,and on the verge of dysfunctional regional economy.Hysteresis type and mild imbalance area economic lag type.The four-quadrant method is used to adjust the economically lagging towns and towns in the mildly dislocated areas.Finally,the land use division of Xishui County is: reluctantly coordinating the eco-environmental lag,reluctantly coordinating the regional economic lag,the dying ecological environment is lagging,and the endangered regional economy There are four types of hysteresis.3.Optimization of land use space in each district: Different optimization conditions are set for different partition optimization strategies.Reluctantly coordinate the ecological optimization zone,follow the social and economic development,pay attention to the quality of the ecological environment,and appropriately increase the ecological land.Under this principle,the total optimization is 1096.527;the economic optimization area is reluctantly coordinated,and the tourism resources and forest resources are abundant,relying on tourism resources.The appropriate development and utilization of land in the district,increase the land for tourism infrastructure,and increase the competitiveness of tourism.Under this principle,a total optimization of 1980.131;the ecological optimization zone on the verge of dysfunction,the land use development degree is large,in the social and economic development,while paying attention to the quality of the ecological environment.The principle is to increase the ecological land use and alleviate the pressure on the land carrying capacity of the area.Under this principle,the total optimization is 11120.97;the economic optimization area is on the verge of dysfunction: the cultivated land resources in this area are rich,the economic development level is not high,the social economy needs further development,and the cultivated land resources are more Enrich,appropriately increase agricultural land,provide development for reforming agriculture,and use rich land resources to promote social and economic development.Under this principle,a total of 1235.248 is optimized.Through optimization and comparison,it can be seen from the landscape index that the problems in various districts have been alleviated to a certain extent,and land use has been sustainable.
