河南中原城市群多情景土地利用优化与碳储量评估
Multi-scenario Land Use Optimization and Carbon Storage Evaluation in Central Plains City Cluster of Henan Province
摘要
Abstract
Land use/cover change(LUCC)is the main factor leading to the change of carbon stocks in ter-restrial ecosystems.It is very important to study and predict the change process of land use and carbon stocks for the sustainable development of urban ecosystems.In this study,9 cities in the Central Plains City Cluster of Henan Province were selected as the research objects.Based on the PLUS and InVEST models,the spatial change characteristics of land use and carbon storage in the cluster during 2000-2020 were ana-lyzed,and the land use and carbon storage in the study area were predicted under the natural development scenario,cultivated land protection scenario and ecological town scenario in 2030.The results showed that 1)from 2000 to 2020,the proportions of land types in 9 cities of the cluster were cultivated land＞forest land＞artificial surface＞grassland＞water area＞bare land,and the expansion rate of artificial surface was the fastest.From the perspective of spatial pattern,the overall pattern of land use changed little from 2000 to 2020,but the local changes were more obvious,and the artificial land surface showed a radiating expan-sion trend from the center to the outside.2)From 2000 to 2020,the carbon reserves of the study areas were in the order of Zhengzhou＞Luoyang＞Pingdingshan＞Xuchang＞Kaifeng＞Jiaozuo＞Luohe＞Jiyuan＞Xinxiang,all of which showed a downward trend during the study period.The regions with obvious changes were the city centers and surrounding areas.3)Hot spots and cold spots of carbon storage in 9 cities of the cluster were scattered in the study area.Under the natural scenario,the distribution range of the cold point of carbon storage tended to increase gradually.Under cultivated land protection and eco-town scenarios,the range of hot and cold spots of carbon storage changed slightly.Therefore,it is suggested to improve the production potential of cultivated land and optimize the spatial pattern of existing land,improve the utiliza-tion rate of urban land,increase urban green land and other measures to reduce carbon storage in the study area.关键词
