| 摘 要： | 应用美国环保署EPA的地下水脆弱性DRASTIC评价方法,考虑地下水位埋深、含水层净补给量、含水层介质、土壤包气带、地形地貌、包气带介质和水力传导系数等7个评价因子,结合GIS技术,对云南丽江古城所在的丽江盆地地下水脆弱性从自然和人类影响两方面进行评价。研究表明,丽江盆地地下水脆弱性高,污染严重,水资源保障率低,已危及丽江世界遗产地下水生态安全。加强对水资源环境的综合研究和保护,是进一步推动丽江社会、经济、环境协调发展的重要工作。

| Abstract: | EPA's DRASTIC method was apllied to evaluate the groundwater vulnerability of Lijiang Basin in the historical city of Lijiang in Yunnan Province with the consideration of depth to the water table,net recharge,aquifer material,soil type,topography,impact of vadose zone and hydraulic conductivity of aquifer from the natural environment and humankind activities with the help of GIS technology.The research results show that Lijiang Basin is of high vulnerability,severe pollution and low security of water resources,which has threatened the groundwater ecology safety of Lijiang heritage site.Enforcing comprehensive research and protection of water resource environment is one of the most important work to make the society,economy and environment harmonious development in Lijiang area. |
