成渝城市群多情景土地利用模拟及生态系统服务权衡协同关系研究
Multi-scenario land use modeling and ecosystem service trade-off synergistic relationship study in Chengdu-Chongqing urban agglomeration
摘要
Abstract
Taking the Chengdu-Chongqing urban agglomeration as the study area,using the relevant data of land use from 2000 to 2020,the PLUS model was used to simulate the land use changes under different scenarios in 2030,and the ecosystem services under different scenarios were evaluated with the help of the InVEST model,presenting the trade-offs and synergistic relationships spatially,which is of great significance to guarantee the regional ecological security and the sustainable development of the region in the future.The results of the study show that:The amount of construction land under different scenarios simulated by PLUS shows an increasing trend,the area of cultivated land under the cropland protection scenario increases significantly,and the area of forest land under the ecological protection scenario increases significantly.The spatial characteristics of ecosystem services differed significantly,the distribution of carbon storage,habitat quality and soil conservation were relatively similar,showing two cores and a circle-like distribution with low in the center and high in the surroundings,and the water production showed a pattern of high in the southwest and low in the northwest.Habitat quality and carbon stock,soil conservation and carbon stock,soil conservation and habitat quality,soil conservation and water production,and habitat quality and water production under different scenarios all showed significant synergies,and water production and carbon stock showed insignificant synergies.By clarifying the impacts of future land use changes on ecosystem services in the Chengdu-Chongqing urban agglomeration,we can provide information for land use decision-making in the region,and provide references for ecological security.关键词
