巖溶是一種起源于碳酸鹽巖與酸性大氣降水發(fā)生溶解侵蝕而形成的一種特殊地質(zhì)現(xiàn)象。巖溶地貌占全球陸地面積的7¹2%,世界上超過25%的人口依賴于巖溶含水層。然而,無論是在地理信息系統(tǒng)領(lǐng)域,還是在巖溶水資源的有限元建模方面,很少有關(guān)于計算技術(shù)應(yīng)用方面的研究。這可能主要是由于巖溶介質(zhì)不均一性強、地質(zhì)結(jié)構(gòu)復(fù)雜,致使其建模難度大。另一個問題是,對巖溶結(jié)構(gòu)特征的刻畫和認識還不夠充分,一般將其視為其他沉積地層。這導致了一些環(huán)境和基礎(chǔ)設(shè)施的破壞,以及巨大的經(jīng)濟損失。盡管存在這些挑戰(zhàn),但在過去十年中仍有一些成功的案例研究。但是,目前還沒有關(guān)于如何在巖溶環(huán)境中進行標準化水文建模的研究。此外,巖溶環(huán)境需要對其潛在的非均質(zhì)性和對環(huán)境風險的敏感性進行特殊處理。正是為了滿足這些需求,本文旨在提高對巖溶流域水文過程和可持續(xù)水資源管理的理解與認識。本文的研究工作概述了一些重要的研究問題,并著手系統(tǒng)地回答它們,目的是開發(fā)一種標準化的方法來模擬巖溶流域的水文過程。這些問題是:（1）巖溶流域與非巖溶流域有何不同?（2）巖溶特征對流域排泄系統(tǒng)有何影響?（3）流域內(nèi)主要巖溶特征對流量的體積貢獻是多少?這些特征...
