土地利用变化视角下生态移民区生态承载力研究
Ecological carrying capacity of ecological migration area from perspective of spatial and temporal changes in land use
摘要
Abstract
To explore the impact of land use changes on regional ecological carrying capacity in ecological migration area,this paper used land use degree index,dynamic degree,transfer matrix and other methods based on land data from 2000 to 2020 to comprehensively analyze spatiotemporal characteristics of land use changes in Hongsibu District in Ningxia since it was delivered from the three aspects of regional land use structure,dynamic change degree and spatial transfer.The ecological footprint method is used to calculate the ecological carrying capacity of Hongsibu District in different periods.The results showed that:① From a time scale perspective,the land use index in Hongsipu District showed a trend of first decreasing,then increasing,and then de-creasing from 2000 to 2020.The absolute values of various types of land area changes from high to low were grassland＞construc-tion land＞cultivated land＞forest land＞unused land＞water area.The absolute values of land use dynamics were construction land＞forest land＞water area＞unused land＞grassland＞cultivated land.② From a spatial scale perspective,the spatial changes in land use in Hongsipu District over the past 20 years have mainly been in a transfer of cultivated land to grassland,grassland to cultivated land and construction land,and unused land to cultivated land and construction land,accounting for 71.1％of the total transfer area.③ The per capita ecological footprint has undergone significant changes from 2000 to 2020,and there was a negative correlation between changes in ecological carrying capacity and ecological footprint.Cultivated land and grassland were the main factors affecting changes in regional ecological carrying capacity.④ Before 2015,Hongsibu District was in an ecological surplus state,but later turned into an ecological deficit.The current ecological sustainability situation in Hongsibu District is worrying.In the future,it is recommended to allocate land resources reasonably,protect forest and grassland resources,control fossil energy consumption,and maintain regional ecological balance and sustainable development.关键词
