Results as following : in the east china sea and the yellow sea, zooplankton showed higher diversity in the low latitude and warm species occurred mainly in the south of 31 n, five communities were distinguished by twinspan method, based on data of species composition and environmental factors. they are : i ) yellow sea neritic community ( f ) with indicator species of labidocera euchaeta in autumn and centropages mcmurrichi in spring ; ii ) yellow sea central community ( hc ) with indicator species of themisto gracilipes, calanus sinicus and euphausia pacifica, the latter two species occurred only in autumn ; iii ) east china sea continental shelf mixed water community ( k ) with indicator species such as rhincalanus cornutus and pterosagitta draco which were confined in waters with high temperature and salinity, iv ) yellow sea and east china sea mixed water community ( he ) and v ) east china sea inshore mixed water community ( m )
根據twinspan等多元分析結果,比較各組群的浮遊動物種類組成和環境特徵,可將東、黃海浮遊動物群落分為5個,黃海沿岸群落( f ) ,指示種秋季為真刺唇角水蚤,春季為墨氏胸刺水蚤;黃海中部群落( hc ) ,指示種以細長腳蟲戎為主,秋季還有中華哲水蚤和太平洋磷蝦;東海外陸架高溫高鹽群落( k ) ,指示種為角錨哲水蚤、飛龍翼箭蟲等多種
狹布型暖水種類;黃東海交匯區群落( he )和東海近岸混合群落( m ) ,兩群落包含多種生態類型種類,其中溫
帶近岸低鹽種在he中較多,廣布性暖水種在m群落中較多。

The shape index tends to increase with growth of the patch area. the shape indices of the forest and the farm landscape between 1. 10 and 1. 30 and the shapes of them are close to rotundity. however, the shape indices of the herbage and the shrub landscape of temperate zone between 1. 30 and 3. 00 and the shapes of them are long and narrow

Taowan conglomerate was formed with underwater seismism at early cambrian period and consists of shattering sedimentary rock, tsunami rock, seismic turbidite and seismic volcanic rock. the shattering sedimentary rock consists of folded rock, cracked rock and autobreccia. the seismic turbidite is located in the south of luonan ductile shear zone and is called the narrow taowan conglomerate. contrarily the broad taowan conglomerate consists of shattering sedimentary rock, tsunami rock located in the north of the zone. the seismic sequence of shattering sedimentary rock - tsunami rock - seismic turbidite - seismic volcanic rock - normal sedimentary rock was first found in luonan shanxi and is rare among the reported examples about it, so it is a good example and offers power evidences to study how the southern marginal basin of huabei plate transferred to qinling orogenic belt
