陇东盆地水资源短缺，严重制约着经济发展，近年来探明白垩系洛河组地层赋存巨厚深层地下淡水。含水层水文地质参数的求解是深层地下水资源评价的关键，用抽水试验确定深层承压含水层水文地质参数是水文地质勘查研究的一项重要的内容。根据单孔、多孔、干扰抽水试验资料，采用稳定流、非稳定流多种方法求解陇东盆地深层含水层水文地质参数，避免了单一方法的偶然性、随意性，计算结果可信。最后探讨了抽水试验场地水文地质条件与所选取公式理论条件的差异对计算结果的影响。
隴東盆地水資源短缺，嚴重製約著經濟髮展，近年來探明白堊繫洛河組地層賦存巨厚深層地下淡水。含水層水文地質參數的求解是深層地下水資源評價的關鍵，用抽水試驗確定深層承壓含水層水文地質參數是水文地質勘查研究的一項重要的內容。根據單孔、多孔、榦擾抽水試驗資料，採用穩定流、非穩定流多種方法求解隴東盆地深層含水層水文地質參數，避免瞭單一方法的偶然性、隨意性，計算結果可信。最後探討瞭抽水試驗場地水文地質條件與所選取公式理論條件的差異對計算結果的影響。

Water resource shortage is seriously restricting the economic development in Longdong basin, but since recent years, exploration has proved very thick underground fresh water in Cretaceous Luohe Formation. It is the key to solve the hydrogeological parameters for assessment of deep groundwater resources. Pumping test used to determine the aquifer hydrogeological parameters constitutes the important content in hydrogeological investiga-tion. According to pumping test data of single well, multiple wells and interference well, various methods for steady and unsteady flow have been adopted to solve the hydrogeological parameters of aquifer, avoiding contin-gency, randomness of a single method, and the calculation results are reliable. Finally, the paper discussed the in-fluence of the difference of hydrogeological conditions at pumping test site and the theoretic conditions of the se-lected formula on the calculation results.
