三峡库区重庆段释氧服务供需关系的时空变化
Spatio-temporal variation of supply and demand of oxygen release services in Chongqing section of Three Gorges Reservoir Area
摘要
Abstract
The oxygen release service is one of the most important functions of ecosystem services and belongs to the gas regulation service function of ecosystem services,which plays an important role in slowing down the trend of global warming and stabilizing the local climate.Taking the Chongqing section of the Three Gorges Reservoir Area as an example,this paper analyzed the spatio-temporal variation of the supply and demand of oxygen release services and their spatial matching conditions from 2000 to 2020 based on ArcGIS,GeoDa,and other software,aiming to provide a scientific basis for optimizing the spatial pattern of the Chongq-ing section of the Three Gorges Reservoir Area.The results show that:from 2000 to 2020,① the total oxygen service supply in the Chongqing section of the Three Gorges Reservoir Area shows an increasing trend and pres-ents a gradually increasing spatial distribution pattern from southwest to northeast regions.② The total demand shows a decreasing trend,and the high-value area is distributed in the densely populated area.③ The overall supply and demand of oxygen release services are well matched,showing a spatial distribution trend of oversupply in the whole region.④ The spatial matching of supply and demand is mainly based on"spatial dislocation of high supply and low demand"and"spatial dislocation of low supply and high demand".关键词
