摘要:
根据峰丛洼地区石漠化治理碳汇的现有研究文献,系统总结了峰丛洼地区石漠化治理过程中的碳储量空间格局及其动态过程、不同模式下的碳汇评价与定量化等方面的研究进展与不足,提出了峰丛洼地区二期石漠化治理应关注碳汇稳定性、受气候变化制约等问题,从而优化资源配置的思路;展望了峰丛洼地区二期石漠化治理工程中碳汇研究的趋势:一方面,将土壤分布格局、碳汇耦合机理研究和增加当地经济效益相结合,提高当地农民参与石漠化治理的积极性,推广和发展第一期石漠化治理工程的成果和经验;另一方面,将遥感技术与石漠化治理碳汇研究相结合,构建更多碳汇估算模型,为二期石漠化治理碳汇定量化服务.
Abstract:
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.
