喀斯特槽谷区土地石漠化与综合治理技术研发

深入揭示流域尺度水-土-生资源格局和研发因地制宜的水-土-生治理技术是"十三五"石漠化治理工程的主要瓶颈。国家重点研发计划——"喀斯特槽谷区土地石漠化过程及综合治理技术研发与示范"项目(2016YFC0502300)针对槽谷区特点,锁定两个关键科学问题和五个关键技术,从过程机理研究-技术研发-应用示范3个层面解剖区域水/土/生物资源分布格局与地质地貌之间的关系,阐明石漠化过程中的相关生态变化机理,因地制宜地研发水土资源高效利用、土壤地上/下流/漏失阻控与生态恢复技术;研发野生砧木及经济树种互作效应与优化配套技术,构建槽谷区可持续的生态系统和生态产业模式并示范推广,为区域生态改善和贫困问题解决提供科技支撑。

Research and development of comprehensive rehabilitation measures for land rocky desertification in karst trough valley area

The bottleneck of the "Thirteenth-five" Program of Rock Desertification Control is to unveil the watershed scale water-soil-biology pattern and develop water-soil-biology restoration technologies corresponding to local conditions. The National key research and development program of China (2016YFC0502300) integrates multi-disciplinary teams to explore the land rocky desertification landscape restoration and for pilot test in the karst trough valley, two key scientific questions and five technologies are the foci of this program. The project will probe the relationships between the distributions of water-soil-biology and landscape and geology, and elucidate the mechanism of the ecological deterioration during the land rocky desertification process, and develop high efficient techniques on soil and water resources utilization and the soil flow/loss prevention upon/underground. Appropriated technologies for better combination the advantages of aboriginal wild rootstocks and economic tree species will be developed, with special aim to reconcile the seemingly conflicting interests between economy development and ecological protection, a sustainable ecosystem and eco-industry model in karst trough valley will be established, which will provide a scientific and technological support for regional ecosystem restoration and poverty elimination.
