摘　　要：大溪河流域环境工程地质问题主要表现为地质灾害、岩溶、水土流失三方面,本文调查和分析了上述问题的基本特征、影响因素及对国土规划的影响;在此基础上,结合大溪河流域的特色,对流域进行了国土功能分区与适宜性评价,分为:林业经济区、农业经济区、河谷经济区三个大区,详细阐述各区环境地质问题及适宜性情况,为流域规划开发决策提供参考建议。The main environmental engineering geological problems of Daxihe basin include geological disaster,karst geology, and soil erosion. Those questions have been analyzed through investigation, involving basic characteristics,influences and land- function regionalization. On the basis, the paper proposes three regions defined as forestry economic Zone, agricultural economic zone, valley economic zone concerning the local features,land- function regionalization and suitability appraisal, and also the detail understanding and suggestion of the following development in the Daxihe basin.
