Research on the Long-Term Effects of Agricultural Activities on the Environmental Geological Characteristics of Shallow Groundwater
农业活动对浅层地下水环境地质特征的长期效应研究

摘要

研究农业活动给浅层地下水环境地质特征带来的长期变化。分析农业灌溉、施肥、农药使用等活动，研究这些活 动对浅层地下水水位、水质和水化学特征的影响。经过研究可知，农业活动改变了浅层地下水的补径排条件，造成水 位上升、水质变坏、元素迁移转化失常。明确这些长期效应，有利于制订科学的农业水资源管理措施，保证浅层地下 水资源的可持续利用，给农业和生态环境协调发展提供依据。

Abstract

This paper studies the long-term changes in the environmental geological characteristics of shallow groundwater caused by agricultural activities. Activities such as agricultural irrigation, fertilization, and pesticide use are analyzed, and their impacts on the groundwater level, water quality, and hydrochemical characteristics of shallow groundwater are examined. The study shows that agricultural activities have changed the recharge, runoff, and discharge conditions of shallow groundwater, leading to groundwater level rise, water quality deterioration, and abnormal element migration and transformation. Clarifying these long-term effects is conducive to formulating scientific agricultural water resource management measures, ensuring the sustainable utilization of shallow groundwater resources, and providing a basis for the coordinated development of agriculture and the ecological environment.
