基于一种土地利用变化新指标的土地利用变化影响因素分析
Analysis of factors influencing land use change based on a new index of land use change
摘要
Abstract
Studying the mechanism of land use change is an inevitable requirement for ensuring the healthy devel-opment of the ecological environment in ecologically fragile areas.A new index,land use conversion degree,was constructed based on land use information Atlas,and the macro characteristics of land use transfer in the study area from 1990 to 2021 were depicted by means of land use transfer matrix and land use conversion degree.A fishing net was constructed to extract land use conversion degree,and its spatial autocorrelation was analyzed.The influencing factors of land use change in the study area were analyzed to serve the social and economic devel-opment of the forest-grazing area.The findings are as follows:(1)From 1990 to 2021,the macro pattern of land use types in the study area has little change.Woodland and grassland are the main land types in the study area.Woodland is mainly distributed in the mountainous areas in the east and north,grassland is mainly distributed in the southwest,and cultivated land is mainly distributed in the area where mountain and grassland intersect and river valleys.(2)From 1990 to 2021,the forest land showed an increasing trend,the grassland decreased year by year,and the cultivated land and construction land increased slowly.(3)Grassland,cultivated land and for-est land are the main types of land use change in this region,and grassland is the most transferred,mainly con-verted to woodland and cultivated land.(4)There is significant spatial autocorrelation of land use conversion de-gree,and there are obvious high aggregation and low aggregation.The frequent conversion area is in an inverted"C"shape,and it is distributed in the transition zone between mountain and grassland in the west of the Greater Khingan Mountains,that is,the zone with an altitude of 700～900 m.(5)GWR found that slope,temperature change and per capita GDP change were the main factors affecting land use in the region,and the increase of per capita GDP would reduce the land use conversion degree,while the increase of other factors would also lead to the acceleration of land use conversion.(6)Land use conversion degree is a reliable measure of land use change,which can integrate space and time to reflect the intensity of land use change.关键词
