In order to promote the further healthy development and disciplinary construction of the rising discipline pollution ecology of soil-plant systems and give full play to its more and more important role in solving environmental pollution and food-chain safety at the national level,this paper reviewed the inceptive work and early researches in this scientific area,traced the development of disciplinary definition and connotation,and basic principles and methods,and expounded and prospected the scientific mission,principal research contents and future development of this subject.

Ascites syndromes disease is a common and ubiquitous disease in the industrial culture with turbot, which often results in turbot's massive mortalities. In June 2006, an outbreak of ascites syndromes disease of the cultured turbot Scophthalmus maximus occurred in an indoor farm in Shandong Province of China Through the isolation, purification as well as cultivation of the bacteria in the diseased fish, and by tracing the bacteria in the well water, rearing pond water along with the feeding trash fish, it was found that the bacterium RF-1 which existed in the trash fish was similar to the bacterium FS-1 in the diseased turbot; artificial infection test demonstrated that the bacteria RF-1 and FS-1 had the same infection symptoms for healthy turbots.

腹水病是工厂化养殖大菱鲆的一种常见病和多发病，常造成鱼类大规模的死亡。2006年6月山东某大菱鲆Scophthalmus maximus养殖场发生大规模腹水病，通过对病鱼细菌的分离、纯化和培养，对养殖井水、养殖池水和所用饵料小杂鱼进行细菌追踪调查，将从该养殖场所用小杂鱼中分离得到的细菌RF-1与鱼体分离的细菌FS-1进行比较，并对其进行人工感染试验，结果证明这2株菌对健康大菱鲆都具有很强的致病性，而且感染症状完全一致。

In June 2006, an outbreak of ascites syndromes disease of the cultured turbot Scophthalmus maximus occurred in an indoor farm in Shandong Province of China. Through the isolation, purification as well as cultivation of the bacteria in the diseased fish, and by tracing the bacteria in the well water, rearing pond water along with the feeding raw fish, it was found that the bacterium RF-1 which existed in the trash fish was similar to the bacterium FS-1 in the diseased turbot; artificial infection test demonstrated that the bacteria RF-1 and FS-1 had the same infection symptoms for healthy turbots.

Many a village Bose, fit only to course a mud-turtle in a victualling cellar, sported his heavy quarters in the woods, without the knowledge of his master, and ineffectually smelled at old fox burrows and woodchucks' holes; led perchance by some slight cur which nimbly threaded the wood, and might still inspire a natural terror in its denizens;—— now far behind his guide, barking like a canine bull toward some small squirrel which had treed itself for scrutiny, then, cantering off, bending the bushes with his weight,imagining that he is on the track of some stray member of the jerbilla family.

许多村中的牛，行动迟缓，只配在储藏食物的地窖里追逐乌龟的，却以它那种笨重的躯体来到森林中跑跑跳跳了，它的主人是不知道的，它嗅嗅老狐狸的窟穴和土拨鼠的洞，毫无结果；也许是些瘦小的恶狗给带路进来的，它们在森林中灵活地穿来穿去，林中鸟兽对这种恶狗自然有一种恐惧；现在老牛远落在它那导游者的后面了，向树上一些小松鼠狂叫，那些松鼠就是躲在上面仔细观察它的，然后它缓缓跑开，那笨重的躯体把树枝都压弯了，它自以为在追踪一些迷了路的老鼠。
