【摘要】：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。
[Abstract]:It is the main bottleneck of the rocky desertification control project in the 13th Five-Year Plan to reveal the pattern of water-soil-living resources on the scale of river basin and to develop the water-soil-growth control technology according to local conditions. The National key R & D Program-"Development and demonstration of the process of Land Rocky Desertification and Comprehensive Control Technology in the Karst trough Valley" (2016YFC0502300), in view of the characteristics of the valley area, locks on two key scientific problems and five key technologies. The relationship between the distribution pattern of water / soil / biological resources and geology and geomorphology was dissected from three levels of process mechanism research, technology development and application demonstration, and the related ecological change mechanism in the process of rocky desertification was clarified. To develop efficient utilization of soil and water resources, control of soil aboveground / downflow / leakage resistance and ecological restoration, mutual effects of wild rootstocks and economic tree species, and optimization of matching techniques according to local conditions, The sustainable ecosystem and ecological industry model in trough valley are constructed and promoted to provide scientific and technological support for regional ecological improvement and poverty solving.
