摘  要:丽江河间地块上岩溶水系统十分发育,查明其径流规律有利于“玉龙-古城”城区科学高效开发利用地下水资源,对地区经济发展和生态环境建设十分重要。作者采用岩溶地下水多层次径流模型对研究区岩溶水径流规律进行分析,查明丽江河间地块岩溶水径流在表层径流、浅径流、深径流不同层次的规律。综合地下水流量分析、水化学反演、同位素测试、示踪试验的结果,对结论进行验证,表明作者提出的径流模型有较好的应用效果。The karst water system on the Hejian formation of the Lijiang River is well developed,and it has been found that its runoff law is conducive to the scientific and efficient development and utilization of groundwater resources in the urban area of"Yulong-Gucheng",and thereby is very important for regional economic development and ecological environment construction.The author analyzes the law of karst water runoff in the study area using the multi-level runoff model of karst groundwater,and finds out the law of karst water runoff in different levels of surface runoff,shallow runoff and deep runoff in Hejian formation of the Lijiang River.Based on the results of groundwater flow analysis,hydrochemical inversion,isotope test and tracer test,the conclusion is verified,which shows that the runoff model proposed in this paper has a good application effect.
