Neglecting the relations between water resources and the ecosystemis a fault of water resources management in the 20th century, which directly causes many questions: the degeneration of ecosystem, the demolishment of the habitat of the wild biology, the withering of the river and wetness, the degradation of the self cleaning of water bodies and so on.

忽视水资源与生态环境系统之间的关系是20世纪水资源管理的失误，直接导致生态环境的退化，引发森林退化、野生生物栖息地破坏、生物多样性减少、河湖湿地萎缩、河道断流、河川淤积、水体自净能力降低、水环境恶化和地下水位下降等诸多问题。

The process of ecological degradation in the vicinity of Shaoguan Pb/Zn smelter may be summed as: heavy metals and acidic deposits from the waste gas from smelter resulted in the vanishment of the sensitive plant species, increasing accumulation of heavy metals in soils and acidification of topsoil worsened the chemical properties and then shallow-rooted plant, mainly the herbaceous, vanished. With the demolishment of the vegetation cover, increasing water-soil erosion worsened physico-chemical properties of soil and, subsequently, some woody plants disappeared and barren land was finally appeared.

该生态系统的退化过程可以归纳为：来自于冶炼废气的重金属和酸沉降导致了敏感植物的消亡，丧失了对土壤的缓冲保护作用；重金属在土壤表层的积累，酸性物质在土壤表层的增加导致的土壤酸化以及由此引发的有机质与养分的淋溶和重金属及Al的活性增加，加剧植被的快速退化，特别是浅根植物的衰亡；地被层的破坏，导致水土流失和土壤侵蚀加深，进一步恶化表层土壤的理化性质，一些木本植物随之消失，最终形成光板地。
