Temporal And Spatial Evolution Of Ecological Land And Its Influencing Factors In Anze County

Land is the foundation upon which humankind depends on for survival and development.It is the material carrier for production and living.Human development and social progress cannot be separated from the support of the land.Instead,it is the most important part of the land—ecological land.Maintaining an important mission of maintaining regional ecosystem stability,but in recent years,with the rapid development of urbanization,its ecological service function is gradually weakening or even gradually lost.The quantity and structure of ecological land use shows new changes,At present,there are few studies on the dynamic changes of ecological land use and they are mainly conducted in hot cities.The research at the county level is basically blank.Therefore,this paper selected Anze County of Linfen City,Shanxi Province as the research object.Anze County is a mountainous agricultural county.It is a national-level ecological demonstration area and a provincial-level ecological demonstration county.Like most areas with rapid urbanization,there are With the problems of irrational land use structure and drastic reduction in ecological land use,in order to study the characteristics of ecological land use change and influencing factors,This paper extracts the second adjustment data of Anze County in 2009 and the status data of land use in 2016,and analyzes the dynamic changes of ecological land use in Anze County in the past ten years by using methods such as land use dynamic degree,land transfer matrix and land use relative rate.From the qualitative exploration and quantitative exploration of the influencing factors of its changes,the principal component analysis is mainly adopted,and the suggestions for the sustainable development of ecological land use are proposed in combination with the development characteristics of Anze County in order to provide a reference for the sustainable land use in Anze County.The findings are as follows:(1)Based on the previous conception and classification of ecological land use,the predecessors defined the connotation of ecological land use in this paper:The types of land use in the region or urban land that mainly provide ecosystem service functions can be improved directly or indirectly.Eco-environment,improve the relationship between people and land in the region,and estimate the value of the ecological service function of each land type,and divide the ecological land into cultivated land,garden land,forest land,grassland,water area and other ecological land.(2)On the basis of clear classification of ecological land use,the dynamic change process was analyzed.From 2009 to 2016,the ecological land use in Anze County decreased as a whole,reducing the total land area by 471.14 hm~2.The proportion has dropped by 0.3%.Except for the reduction of the area of gardens,forest lands and grasslands,all other land types have increased to varying degrees.In particular,the area of cultivated land has increased the most,and the area of forest land has decreased most.The area and the smallest proportion of all the land in the garden The conversions between land use types are complex and mainly involve the conversion of cultivated land,garden land,forest land,construction land and other ecological lands.The largest amount of transferred out of the garden was the cultivated land.Within towns and towns,the largest difference is grassland,and the least difference is the garden area.Among them,the relative change rate of ecological land in Mabi Township is the largest,and that in Minshi Town is the smallest.(3)The reason for the change of ecological land use in Anze County is multi-level,which is the reason driven by many factors.Among them,the natural factors are relatively stable,they mainly play a cumulative role,the human factors are more active,and the selected14 indicators are adopted.The analysis of principal components shows that economic development,increase of population and improvement of living standards are the main reasons for the change of ecological land use.Finally,based on the analysis of the characteristics of ecological land use change and influencing factors,some suggestions are proposed that are beneficial to the sustainable development of ecological land use in Anze County.
