目前大部分研究已注意到海洋酸化造成珊瑚钙化作用的减缓，以及礁石有机物、某些主要浮游生物群所受到的影响；但对生态系统「脱钙作用」的发生会造成什么长远的效果，则所知甚少。

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。

Primary results are shown as followings: 1. PH measuring results of soil solution and eluviation solution show that the ability of experimental plot the acid buffer capacity of soil is stronger under the experiment condition,there is no obvious acidification in soil which after acid rain eluviation. The result has substantial differences with that gotten by most of investigationers in similar work before.

这一结果与以往类似研究中多数研究者得到的结论存在本质区别，原因可能在于此次试验的试验条件与以往研究的试验条件不同，其中最主要一点是在本次试验中使用的土壤样品的重量比以往试验均显著增大，而且使用的是土壤结构和组成等均未经破坏的原位土，从而使入渗酸雨与承受酸雨沉降的土壤之间的比例关系更接近自然酸雨沉降过程，以此为基础得到的试验结果应该更加客观、可靠。

In order to complete the investigation, impersonality feasible experiment solutions and devices are designed independently to systemically investigate on activation and transfer characteristic of soil heavy metal under acid rain effect. Primary results are shown as followings:1. PH measuring results of soil solution and eluviation solution show that the ability of experimental plot the acid buffer capacity of soil is stronger under the experiment condition,there is no obvious acidification in soil which after acid rain eluviation.The result has substantial differences with that gotten by most of investigationers in similar work before.
