侵蚀

Soil erosion is one of the main environmental problems in the world ,it is the root cause of land deterioration 、 soil fertility degression、 soil physico -chemical quality bad、 land use capability felling and ecological environment deterioration.

土壤侵蚀是世界上的主要环境问题之一，是造成土地退化、土壤肥力下降、土壤理化性质变劣、土地利用率降低、生态环境恶化的根本原因。

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。

The cause of formation is the new structure rising of the earth's crust and the erosion and denudation of the external force.
