摘要 【目的】探讨农业土地利用过程中喀斯特浅层地下水化学变化及农业种植活动对地下水质量的影响。【方法】在贵州中部喀斯特石漠化地区对不同生态区(阔叶林区、农林交错区、旱作农业区、复合农业区)进行植被和土壤调查及浅层地下水和地表径流水的采样分析。【结果】喀斯特石漠化区生态模式从阔叶林生态系统-农林生态系统-旱作农业生态系统-复合农业生态系统方向的演替过程中,其浅层地下水的HCO3-、SO42-、Ca2+、Mg2+、Na+、K+、NH4+、Cl-、PO43-、NO3-、Pb的含量发生了明显的变化,在以种植玉米为主的低复种指数地区表现为NH4+及Pb、Cd含量的增加,而在以种指玉米或水稻、疏菜或油菜的高复种指数地区则表现在NO3-、SO42-、NH4+及Pb、Cr和Cd含量的增加。【结论】高复种指数农业区地下水的化学组成发生了明显地变化,浅层地下水质量出现一定程度的下降;作物种植结构和施肥水平是影响地下水质量的重要因素,在喀斯特地区发展农业生产的同时要兼顾地下水资源的保护。 【Objective】This paper focused on chemical composition changes of shallow groundwater in agricultural land usage and the effects of agricultural planting activity on the quality of shallow groundwater. 【Method】The vegetations and soils were investigated, and groundwater and runoff were sampled in various agricultural ecological areas of karst rocky desertification areas in Guizhou province. 【Result】Under the order of ecological pattern from forest ecological system, forest-agriculture ecological system, dry ...
