This rich variety of genes , species , and biological communities gives us food , wood , fibers , energy , raw materials , industrial chemicals , and medicines - all of which pour hundreds of billions of dollors into the world economy each year 基因、物种和生物群的丰富的多样性给我们带来了食物、木头、光纤，能量，原料，工业用的化学药品和医学用药，所有的这些每年都给世界经济注入好几千亿美圆。
The geological setting of chengjiang biota firstly , the pattern of chinese tectonic has been cited , which can help us to understand the place of china in the world clearly and easily . secondly , the lower cambrian of china and the early cambrian geomorph of eastern yunnan have been included 澄江生物群的地质构造背景首先介绍了中国区域大地构造格局，其次是关于中国的寒武系和滇东地区早寒武世古地理概貌的论述，紧接着是澄江化石库的古地理概貌。
Comparison and study of the biotic characters in the jinggu and longchuan basins in yunnan province show that : ( 1 ) the two basins underwent the developing period , expanding period and shrinking period from early miocene epoch to pliocene epoch ; ( 2 ) the climate in the region was dry in early miocene epoch , warm and humid in middle - late miocene epoch and dry in pliocene period ; ( 3 ) the basins expanding in middle - late miocene epoch formed a semi - deep - lake to deep - lake environment 通过对云南景谷盆地及陇川盆地新生代生物群特征的对比，探讨了新生代两大盆地环境演变：早中新世到上新世为湖盆发展期湖盆扩大萎缩期，气候为早期的千燥中新世早期的温暖湿润中新世中晚期的寒冷阴湿上新世的干燥，而中新世中晚期湖盆的扩大形成的半深湖深湖环境为油气的形成提供了有利条件。
Abstract : comparison and study of the biotic characters in the jinggu and longchuan basins in yunnan province show that : ( 1 ) the two basins underwent the developing period , expanding period and shrinking period from early miocene epoch to pliocene epoch ; ( 2 ) the climate in the region was dry in early miocene epoch , warm and humid in middle - late miocene epoch and dry in pliocene period ; ( 3 ) the basins expanding in middle - late miocene epoch formed a semi - deep - lake to deep - lake environment 文摘:通过对云南景谷盆地及陇川盆地新生代生物群特征的对比，探讨了新生代两大盆地环境演变：早中新世到上新世为湖盆发展期湖盆扩大萎缩期，气候为早期的千燥中新世早期的温暖湿润中新世中晚期的寒冷阴湿上新世的干燥，而中新世中晚期湖盆的扩大形成的半深湖深湖环境为油气的形成提供了有利条件。
During the primary research work of chengjiang biota , the paleontologists had an idea that the bivalved arthropod kunmingella douvilleiyas the dominant species because they found that eighty percent of the fossils they excavated in chengjiang fossil lagerstatte were kunmingella douvillei . and they also found that naraoia longicaudata , naraoia spinosa and isoxys auritus which belong to arthropoda were the sub - dominant species 在澄江生物群研究初期，双瓣壳节肢动物朵氏昆明虫( kunmingelladouvillei )化石数量占澄江化石库中所有化石产量的百分之八十，因而古生物学家曾认为kunmingelladouvillei是该库的优势种。
There are 25 genera and 47 species of conodont , 4 genera and 6 species of coral and some foraminifera . ch . 4 biostratigraphical regions based on the study on the conodont , coral and foraminifera fossils in research area , it was discovered that the biota features are resemble to the south china . so a conclusion can be drawn that the research area and south china belong to the same biogeographical region 生物地层分区本文通过对牙形刺、蜒类、珊瑚等化石的对比研究，发现研究区的生物群特征与华南区生物群相近，这表明在该区早、晚石炭世与华南区及东古特提斯区同属一个生物地理区系。
