由于人为因素与自然灾害的影响,作为珠江水系和湘江水系主要发源地的桂北山区固有的生物链遭到撕裂,生物多样性被破坏,人类和其他生物赖以生存的水资源大幅减少,水环境面临愈来愈严重的威胁。科学分析这一现状,寻求修复涵养水资源的对策,消除水环境危机,已经成为刻不容缓的大事。 Due to human factors and natural disasters, the inherent biological chain in the mountainous areas of northern Guangxi as the birthplace of the Pearl River and Xiangjiang River systems has been torn apart, the biodiversity has been destroyed, and the water resources that depend on human beings and other living organisms have drastically decreased. Water environment is facing more and more serious threats. To scientifically analyze this status quo and seek solutions to water conservation and eliminate the crisis of water environment has become a pressing task.
