There has been a certain recognition to sediment source , migration direction , depositional system distribution and reservoir favorable zones within sequence . ( 7 ) reservoir heterogeneity is strong in intra - system tracts and in inter - system tracts 對(duì)凹陷內(nèi)各層序(體系域)沉積時(shí)的物源、搬運(yùn)方向、沉積體系分布和有利儲(chǔ)層發(fā)育帶,都有了較確切的認(rèn)識(shí)。
Analyses of grain size and mineral components of surface sediments in the offshore area of the northeastern shandong peninsula were carried out to reveal the sediment source and the relationship between the characteristics of grain size distribution and sedimentary dynamic conditions in the littoral zone off the northeastern shandong peninsula 摘要對(duì)山東半島東北部濱淺海區(qū)海底表層沉積物的粒度和礦物組分進(jìn)行了分析,探討了其物源及其粒度分布特征與沉積動(dòng)力條件的關(guān)系。
Through the analyses of characteristics of gully thalweg and soil erosion in upland and gully land , sediment sources in small watershed , sediment yield relationship between upland and gully and ecological functions of vegetation corridor , it is considered that vegetation corridor combined with land preparation measures may block runoff and sediment from upland and reduce the amount of soil erosion in a watershed by 54 . 5 % ~ 77 . 0 % 摘要在分析黃土高原地區(qū)的溝沿線、溝沿線上下溝間地和溝谷地土壤侵蝕特征、小流域泥沙來(lái)源、坡溝侵蝕產(chǎn)沙關(guān)系的基礎(chǔ)上,結(jié)合廊道的生態(tài)功能和以往的研究結(jié)果,認(rèn)為在溝沿線的上部建立草灌與整地工程措施相結(jié)合的植物廊道,來(lái)攔蓄阻截溝間地的來(lái)水來(lái)沙,可使流域的土壤侵蝕量減少54 . 5 % ~ 77 . 0 % 。
