中文摘要	针对2016年度国家重点研发计划项目喀斯特断陷盆地石漠化演变及综合治理技术与示范之课题一断陷盆地生态环境地质分异及石漠化演变机理,旨在揭示喀斯特断陷盆地碳、氮、钙、水在生态系统中的迁移规律,阐明生态系统演替和石漠化演变过程及驱动机制。为此,选择蒙自盆地南洞地下河流域和泸西小江喀斯特盆地流域石漠化治理示范区,在对岩性、地形、地貌、生态水文、植被、社会经济、气象、土壤等因子分异特征研究的基础上,利用径流小区定位观测、同位素技术、生态化学计量学和模型模拟预测等技术手段,定量刻画典型流域植被与水文过程的交互作用,确立流域生态需水关键期及需水量,明确植被生态水文耦合过程对碳、氮、钙、水等物质传输的影响,评价生态系统碳固持能力,获取影响生态系统演替和石漠化演变过程的关键控制因素,预测生态系统演替和石漠化演变趋势,进而为喀斯特断陷盆地石漠化区面向生态的水资源合理配置和生态功能恢复提供理论依据。
英文摘要	According to the national key research and development program of ChinaEvolution,integrating treatment and technological demonstration of rocky desertification in karst graben basin,the task ofecological, environmental and geological differentiation of rocky desertification and its driving mechanism in karst graben basin was to reveal the migration of carbon,nitrogen,calcium and water,as well as evolution process and driving mechanism of ecosystem succession and rocky desertification. In this respect,the factors of lithology,topography, ecology,hydrology,vegetation,socio-economy,meteorology,soil,etc. were studied in the demonstration areas of Mengzi and Luxi rocky desertification control. Moreover,the interaction between vegetation and hydrological processes in the typical watershed was established,and the critical period and water requirement of the ecological water demand in the watershed were established. The ecological and hydrological process of the vegetation,as well as nitrogen,calcium and water cycling,and the carbon sequestration ability of ecosystems were used to predict the evolution of ecosystem succession and rocky desertification. The results provided the theoretical basis for the rational allocation of ecological water resources and ecological restoration in rocky desertification area.
