Carbon sink in rocky desertification restoration, Southwest China: A case of the peak-cluster depression areas

The vulnerable environment and unreasonable human activities have resulted large scale of karst rocky desertification (KRD) in Southwest China,accompanging huge carbon stocks loss.To introduce the studies on carbon sink in the processes of KRD restoration projects in the peak cluster depression areas,Southwest China,this paper,based on literature analyzing,summarizes the progress and shortcomings on the carbon spatial distribution and its dynamic processes,as well as the evaluation and quantitative measurement of carbon sink under different patterns KRD restoration projects.In the next work,the second term of KRD restoration project should focus on water and soil conservation,rocky desertification prevention,and taking vegetation construction as a supplement.According to the available results on soil surveys,carbon sink mechanism,and local economic crops growing,it is a good chance to optimize the allocation of resources so that the government can make sure short-term benefits to local farmers.As a reward,more farmers will agree with the KRD restoration projects to create a sustainable and green industral chain.
