| 中文摘要:自第三纪以来, 康滇地块的地壳运动十分活跃, 形成了喀斯特断陷盆地。由于该区“盆-山”地形变化剧烈, 山地气候反差大; 而西南季风的控制, 使得该地区旱季是雨季的2倍, 水资源的时空分配不均, 土壤流/漏失严重, 植被立地条件差, 以至于石漠化问题缓解不明显。2016—2020年, 在该区实施了国家重点研发计划典型脆弱生态修复与保护专项项目“喀斯特断陷盆地石漠化演变及综合治理技术与示范”, 为我们了解喀斯特断陷盆地关键带与生态地质特征、总结已实施石漠化综合治理工程成果提供了条件。在《地球学报》编辑部的大力支持下, 从4个方面“水资源、水土流失、生态地质、生态服务”, 15篇文章构成“喀斯特断陷盆地关键带与生态地质”专辑, 专辑并没有包括专项项目的全部内容, 但对深入了解喀斯特断陷盆地的地质、气候、水文、生态和生态服务功能提供重要的参考价值。 |

| Abstract:The crustal movement of Kang-Dian block has been extraordinarily active since the Tertiary, resulting in the formation of the karst graben basin. Due to the dramatic changes of the “basin-mountain” topography in this area, the climate shows tremendous contrasts. Simultaneously, the control of the southwest monsoon leads to the dry season twice as much as the rainy season in this region, and the uneven distribution of water resources in both spatial and temporal aspects. Moreover, soil flow/leakage is serious and vegetation site conditions are poor. Then, rocky desertification here cannot be easily controlled. During 2016 to 2020, “Evolution of Rocky Desertification in the Karst Graben Basin and Comprehensive Treatment Technology and Demonstration” under the support of the national key research and development program was implemented in this region, which provided us an approach to better understand karst critical zone and ecological geological characteristics. Under the substantial support of Acta Geoscientica Sinica, 15 articles, which embrace four aspects of “water resources, water and soil erosion, ecological geology, and ecological services”, form the special issue of “Critical Zone and Eco Geological Environment in the Karst Graben Basin”. Though this special issue does not include the entire content of the special project, it provides a paramount significant reference value to understand the geology, climate, hydrology, ecology, and ecological service functions in the karst graben basin. |
