More than 80 species have been collected and 18 of them including six new species and 12 new geographical records have been worked out in china . they are : comesoma , comesomatidae ; pomponema , cyatholaimidae ; marylynnia , cyatholaimidae ; pterygonema , ceramoneniatidae ; metachromadora , desmodoridae ; desmoscolex , desmoscolecidae aponema , microlaimidae ; gammarinema , monhysteridae ; metadesmolaimus , xyalidae ; rhynchonema , xyalidae ; xyala , xyalidae ; viscosia , oncholaimidae we found divergence in the species composition in different habiting area ( mud flat and sand flat ) . the investigation put emphasis on some area , try to know the distribution of marine nematodes for the later research of the position of marine nematodes in the benthic eecological system 這十一個屬包括:聯體線蟲科( comesomatidae )的聯體線蟲屬( comesoma ) ;杯咽線蟲科( cyatholaimidae )的華麗線蟲屬( pomponema ) ;杯咽線蟲科( cyatholaimidae )的瑪里林恩線蟲屬( marylynnia ) ;覆瓦線蟲科( ceramonematidae )的翼紋體線蟲屬( pterygonema ) ;鏈環線蟲科( desmodoridae )的后菱光線蟲屬( metachromadora ) ;微咽線蟲科( microlaimidae )的厚甲線蟲( aponema ) ;單宮線蟲科( monhysteridae )的嗜鯨線蟲屬( gammarinema ) ;希阿利線蟲科( xyalidae )的后棘線蟲屬( metadesmolaimus ) ;希阿利線蟲科( xyalidae )的吻腔線蟲屬( rhynchonema ) ;希阿利線蟲科( xyalidae )的雙翼線蟲屬( xyala ) ;瘤線蟲科( oncholaimidae )的顯齒線蟲屬( viscosia )此外我們報道了六個新種,并對一些已經報道過的蟲種進行重新的描述和討論。

Tide is the primary dynamic factor in building tidal flat ; it must be affect tidal creek system on mud flat . therefore , based on the raster image of the year of 2000 , the thesis has built correlation equations between average tidal ranges and the density of tidal creeks , the ratio of the width of outlet to the length of low tidal shore , the ratio of the area of tidal creek to tidal basin respectively . the result shows that the former is high well - marked correlation ; the two latter are well - marked correlation 潮汐是塑造潮灘的主要動力因素,它必然與淤泥質潮灘上潮溝系統的發育有密切的關系,為此,本文以2000年的衛片作底圖,對潮溝系的密度、溝口寬度占低潮線長度的比值以及潮溝面積與潮盆面積的比值,分別與平均潮差建立了相關關系,結果發現,潮溝系的密度與平均潮差之間存在著高度顯著的相關性,溝口寬度占低潮線長度的比值和潮溝面積與潮盆面積的比值與平均潮差之間存在著顯著的相關性。

Traditionally , oysters are cultured by the bottom culture method with spat collected by laying rock , concrete tile or post as cultch on the mud flat in may or june . the oyster spat takes four to five years to grow to marketable size 傳統上,香港養蠔都是使用海底養殖法,在5月或6月間在泥灘上放置石塊、瓦片或柱桿作為附器收集蠔苗,這些蠔苗要生長4至5年才可收成售賣。

Within the 10 meter depth contour there are 69 , 600 hectares of shallow mud flat fit for sea culturing . the major cash aquatic products are of 214 species , 120 families and 21 kinds . the area of salt field is 1677 . 6 hectares 3萬公頃,主要經濟水產品有14類107科173種,淡水主要經濟水產品有7類13科41種;且為粵東著名產鹽基地,現有鹽田面積167770公畝;全市有林面積20

Culture of oyster has been practiced along the intertidal mud flat of deep bay in northwestern corner of hong kong ( see figure ) for at least 200 years 蠔的養殖一直以來是在香港西北部的后海灣沿岸潮間帶泥灘進行的,迄今至少有200年的歷史(見圖) 。
