Spatiotemporal Evolution and Prediction of Carbon Storage During the 14th Five Year Plan Period Based on InVEST and CA-Markov Models——A Case Study of Zhangjiajie City
Based on multi-scenario simulation of carbon reserves of different land use types,suggestions are pro-vided for achieving tourism and ecological development in Zhangjiajie City.Taking the land use changes in Zhangjiajie City in 2000,2010,and 2020 as the starting point,based on the InVEST model and CA Markov model,spatial scenario simulation and quantification of carbon reserves under different spatiotemporal land use types are conducted to explore the land use and carbon storage change patterns under different scenarios.The results show that Zhangjiajie City is mainly dominated by forest and farmland,and the increase in construction land are mainly farmland and grassland;Carbon storage exhibits significant clustering in spatial distribution;The carbon storage has shown a decreasing trend year by year,with a total decrease of 0.35 × 106 t.Under different scenario simula-tions,the total amount of carbon storage loss compared with 2020 is 3.44 × 106,3.04 × 106,3.99 × 106 t,and 4.93 × 106 t,respectively.The current land use situation under the comprehensive development scenario is the most reasonable,which can provide a basis for regional carbon balance and land use structure optimization,and help Zhangjiajie City achieve the"dual carbon"goal and high-quality tourism development.
