摘　　要：水系形态是内外动力条件共同作用的结果,通过分析水系形态特征参数,可以获取流域内河流排泄能力、河流侵蚀能力、地表水下渗能力等信息。清江流域是三峡岩溶区典型的山区河流,由于交通条件的限制,如何快速高效地掌握清江流域的地下水资源总体分布特征,一直是该地区水资源调查工作的难点。为了解决上述问题,使用Aster GDEM数据对清江流域的24个子流域(SW1-SW24)的6个线性参数、8个面状参数以及3个起伏度参数进行分析。依据不同的参数所指示的地下水潜力特征,将每个参数赋予一个序列值。将不同参数的序列值求和后的新序列作为不同子流域的优先级序列。通过对比地下水水位统测工作得到的泉流量信息,对优先级结果进行了验证。发现清江流域的优先级与地下水资源潜在区有较好的对应关系,流域的优先级高的流域也是地下水资源丰富的地区。清江流域中游北岸地区地下水资源量最为丰富,上游次之,而在下游以及南岸地区较少。揭示了DEM数据在水系特征评价和相关参数提取中所起到的重要作用,为水资源评价和管理工作提供了新的思路。Stream morphology result from the combined effect of internal and external dynamic conditions. Capacities of the river basin, such as river drainage, river erosion, and surface and water infiltration, can be obtained using morphometric analysis. The Qingjiang River is a typical mountain river basin in the Three Gorges karstic area. The rapid and efficient grasping of the overall distribution characteristics of groundwater resources in the Qingjiang watershed has been a challenge in water resources surveys in the area. For the above problem, Aster GDEM data were used to analyze 6 linear, 8 aerial, and 3 relief features of 24 sub-watersheds according to the groundwater potential characteristics indicated by different parameters. Each parameter is assigned a sequence value. The sum of the sequence values of different parameters is used as the priority sequence of different sub-watersheds. Further more, the results validated with the discharge of the springs, show that the prioritization of the Qingjiang watershed is well correlated with the groundwater potential zones. The higher prioritization basins are likewise areas of abundant groundwater resources. In Qingjiang catchment, comparing with upper and lower reaches of Qingjiang River, the northern tributaries in the middle reaches are abundant in groundwater resources. This study reveals the importance of DEM data in the evaluation of water system features and in the extraction of the related parameter, and provides new ideas for water resources evaluation and management.
