摘　　要：随着城市化建设进程的不断加快,广西砂石需求量日渐增大,河道采砂作为建筑用砂的主要来源之一,不尽合理的采砂规划,简单粗暴的作业方式,不规范、不标准的监督管理对河道水生态环境系统都产生了巨大的影响,大规模的河道采砂会导致河床下切,河势失稳,河道生物多样性下降,水生态系统遭到破坏。本文对当前河道采砂影响水生态的几个主要方面进行分析、探讨,并提出了应对措施,为采砂行业监督管理提供参考。With the continuous acceleration of the urbanization process,the demand for sand and gravel in Guangxi is increasing day by day.River sand mining is one of the main activities as sand sources for construction.Unreason-able sand mining planning,simple and rough operation methods,irregular and non-standard supervision and man-agement have had a huge impact on the river water ecological environment system.Large-scale river sand mining can lead to the undercutting of the river bed,unstable river conditions,reduced river biodiversity,and destruction of the water ecosystem.This article analyzes several main aspects of river sand mining influencing water ecology,puts forward countermeasures,and provides reference for the supervision and management of the sand mining industry.
