Research On The Coupling Relationship Between Land Use And Ecological Environment In Guizhou Province

Guizhou Province is an important ecological civilization pilot area in China,in recent years,with the economic development of land use change led to a series of environmental problems.It is especially necessary to study the temporal and spatial coupling between land use and ecological environment in this province.Based on the connotation of land utilization and ecological environment,combined with the economic status of Guizhou Province,land use status and ecological environment,this paper analyzes the coupling mechanism of land use and eco-environment in Guizhou Province by using DPSIR conceptual model,In addition,by comprehensively utilizing the index system of evaluating the coupling relationship with the ecological environment,the temporal-spatial coupling of land use and ecological environment in Guizhou Province was calculated by comprehensively using the entropy method,the coefficient of variation coefficient method,the coupling degree and the coupling coordination model,Finally,it puts forward some countermeasures and suggestions on how to promote the coupling between land use and eco-environment in Guizhou Province.Get the following conclusion:(1)By constructing a driving force-pressure-state-impact-response(DPSIR)model,the coupling relationship between land use and ecological environment in Guizhou Province has totally shown an upward trend over the past 12 years,which had a slight decline in 2010-2011 years,then quickly picked up again,reached the peak by 2014;(2)Coupling degree and coupling development degree model are used to evaluate the coupling relationship of land use and ecological environment in Guizhou province,from the time point of view,the overall coupling degree of land use and ecological environment in Guizhou Province is higher,the coupling degree is maintain over 0.9 from 2004 to 2015,the development of land use and ecological environment alone shows a trend from low to high,in respect of coupling coordination degree,the development of coupling coordination degree of land use and ecological environment in Guizhou province has gone through five stages,it is an uncoupling phase phase in the year 2004-2006,an bare coupling phase in the year 2007-2009,developing into a primary coupling phase in the year 20010-2011,the good coupling phase in the year 2012,the intermediate coupling phase in the year 2013-2015?(3)The coupling degree and coupling coordination degree of land use and ecological environment in Guizhou Province in the next ten years were measured and calculated by gray prediction method.The prediction results show that the land use and ecological environment index of Guizhou province will increase in the next ten years according to the current mode of development,but the gap between the two will be bigger and bigger.If large-scale change does not occur to Guizhou Province,the future level of land use and ecological environment will be higher and higher;from a spatial point of view,in 2016,land-use good coupling development of Guiyang City was ecological lagged type,showing that the development of land use level in Guizhou province is higher than that of ecological environment level;(4)The coupling development types of land use and ecological environment in states in Southeast if Qian belong to land use lagged type of uncoupling development type,the coupling degree of land use and ecological environment is very low;the coupling development types of land use and ecological environment in Bijie belong to land use lagged type of uncoupling development type,the coupling coordination degree of land use and ecological environment is very low.To this end,respectively from such four aspects as implementing comprehensive treatment of ecological environment,establishing ecological environment compensation mechanism,developing circular economy,vigorously promoting clean production,playing the role of overall land use planning in the protection of ecological environment,constructing the model of ecological environment friendly land use,and ensuring the sustainable use of land,the countermeasures to improve the coupling development level of land use and ecological environment have been put forward.
