長江江豚在洞庭湖的分佈范圍主要集中在從城陵磯到鯰魚口一帶，其種群數量大致為100 150頭。The analyzed results are as follows : the late 1960 ' s cutoff of riverbends increased both the runoff amount and the sediment transport amount of the lower reach of jingjiang river, while the sediment deposition decreased in the lkngting lake area ; after the mid 1980 ' s, both the middle reach of yangtze river main stem and the dongting lake occurred a trend of decreasing annual sediment transport as a result of decreasing sediment releasing from the upper reach of yangtze river ; and in the recent 3 years ( 2003 - 2006 ), the three gorges reservoir first impoundment additionally reduced the sediment concentration in the middle reach of yangtze river flow with a long time, so a distance would be quite long for suspended sediment recovery, but the distance for bed - material load of suspended sediment recovery would be quite short
分析結果表明： 20世紀60年代下荊江裁彎后，三口（松滋口、太平口、藕池口）分流分沙減少，下荊江徑流量和輸沙量相應增加，洞庭湖泥沙淤積減少； 80年代中期以後，長江中游幹流及洞庭湖出口的年輸沙量呈減少趨勢，城陵磯至武漢河段河床由淤積轉為趨向沖淤平衡；三峽工程初期蓄水運用后，長江中游含沙量沿程恢復距離較長，但床沙質部分恢復距離相對較短。This paper describes unique succession of calcareous tempestite from the early cambrian qingxudong formation, northeastern guizhou province
摘要在黔東北銅仁江口地區下寒武統清虛洞組下部發育一套特徵典型、序列特殊的鈣質風暴巖。Surface, the easliy wear and tear parts use grinding - resistant material, extruding part use variable cylinder diamethe extruder with compact structuures, transmission gear with hard gear ter detachable pitch, great extruding p0ressure, high vacuum degree, low loading capacity ( electricity - saving more than 25 % than the same product ). it reaches advanced domestic level andcan replace imported items. it is suitable to produce hollow brick with high hole ratio, coal waste rock hollow bricks, shale hollow bricks, prower coal ash hollow - bricks. the extruder won the scienttific and technological progress pride of the lst building material scientific and techniques achievement exhibition in jiangsu province and the golden prize of the mational brick and tile energy - saving lxln achievement
