The longdong river capture between yufu river and daxin river in jinan city , took place in the early quaternary , when the denudation surface of yangping period has already formed and the quaternary tectonic upheaval began to start . the yiyuan river capture between yihe raver and dawen river , was formed in holocene 濟南龍洞河流襲奪是仰平期剝夷面形成后，魯中南山地第四紀構造抬升初期發生的襲奪現象；沂源河流襲奪則是在晚更新世晚期至全新世發生的襲奪現象。

The study results can be summerized as following aspects : ( 1 ) the basic settling curve of this basin was broken - line shape of seven sections in which upper jurassic , lower cretaceous , eocene , oligocene and neogene corresponded with the decline ones representing five episodic clear subsidences of this basin , late cretaceous to paleocene and early miocene corresponded with the rising ones reflecting the uplift and denudation of this basin . ( 2 ) the subsidence of this basin migrated from the east to the west , from mesozoic to cenozoic 研究表明： ( 1 )北黃海盆地的基本沉降曲線型式為7段折線狀，其中晚侏羅世、早白堊世、始新世、漸新世、新近紀為曲線下降段，代表盆地5幕較明顯的沉降；晚白堊世古新世以及中新世早期為曲線上升段，反映盆地的抬升剝蝕。

Bachu arch is a common forland uplift of southwest of tarim forland basin northeast of tarim forland basin . this arch previously is a low submerged paleohigh which rised integrality above water from late hercynian to terminal hercynian , was exposed to denudation mostly because of uplifting integrality in mesozoic , ulteriorly uplifted and strongly reformed in late himalayan . markit slope is a slope north dipping in early paleozoic , tilted in south - north orientation in hercynian 巴楚隆起作為塔西南前陸盆地和塔東北前陸盆地的共用前陸隆起，是一個早古生代潛伏于水下的低隆，海西晚期至末期呈整體性隆升，露出水面，中生代整體隆升，大面積遭受剝蝕；喜馬拉雅晚期進一步隆升和強烈被改造，才定型成現今的構造格局。

Based on the data of vector topographic map , the geomorphologic evolution stage of csmasp is studied with the aid of maplnfo and arc view . it is indicated that the research area is in the middle age and old age according to the davisan stage determine of geomorphologic evolution . the uplift and denuded amount in the period of neo - tectonics and the elevation of denudation surface of lincheng period ( mainly in quaternary ) are also discussed 根據高程分析結果，認為魯中南山地主要處于流域地貌發育的壯年、晚年期，并對魯中南山地第四紀構造抬升量與侵蝕速率、各流域臨城期山麓剝夷面的分布高度等相關問題進行了理論探討，從理論上證明了魯中期剝夷面難以存在。

Many times structure movements of huanhua basin result in many times water progradation and retrogradation . cycle sediment in portrait and stratum lapout & denudation in plane and vary of different types sand body are resulted in sediment process . it provides better condition for subtle trap 研究表明，黃驊坳陷構造運動的多期性形成多次水進水退，在沉積上產生了縱向的多旋回性和平面上的地層超覆與剝蝕以及不同類型砂體的變化，為隱蔽油氣藏的形成提供了良好條件，盆地中區是隱蔽油氣藏較為集中的分布區。

Yinggete - bagemaode metamorphic core complex belt with three - layer construction is put forward , which evolved from late jurassic to cretaceous . the extensional simple shear model of the chagan fault depression is established . the tectonic evolution and the dynamics character of chagan fault depression and its adjacent mesozoic - cenozoic basins are discussed : at the end of triassic continental orogeny increased crust thickness crust uplift and denudation were happened ; jurassic was a period of local partly extensional collapse of erogenic belt and cretaceous was a period of widely extensional collapse of postorogenic erogenic belt ; cenozoic was a period of the development of stable intracontinental depression with the character of long distant collision response and weaked compression flexure 討論了查干凹陷及鄰區中-新生代盆地構造演化及其地球動力學特征，三疊紀(印支期)為陸內造山作用與地殼增厚、隆升剝蝕階段；侏羅紀(燕山早期)為造山后造山帶的局部伸展垮塌階段；白堊紀(燕山晚期)為造山期后大規模伸展垮塌作用與伸展盆地的發育階段；新生代(喜山期)為遠距離碰撞效應與弱擠壓撓曲性質的穩定大陸內坳陷的發育階段。

On the basis of the types of sand stone , light and heavy mineral associations , planimetric map of sedimentary facies and directions of palaeoflow , it is considered that detrital material of terrigenous deposit of chang6 - 8 oil - beds in this area come from southwest provenance , northeast provenance , west provenance and south provenance , respectively , which are the denudation area of huating - longxian county in southwestern , yinshan ancient land in the northern , the denudation area of yantong mountain and tongxin to the west of yangjiajuzi - yinjiacheng county and qinling ancient land in the southern 根據砂巖類型、輕、重礦物組合、沉積相帶平面展布及古水流方向等特征的分析，認為研究區延長組長6 ? 8油層組陸源碎屑物質來自西南、東北、西部和南部四大物源區，分別為西南華亭?隴縣一帶剝蝕區，北部陰山古陸，西部的楊家咀子、殷家城以西的煙筒山、同心地區剝蝕區和南部秦嶺古陸。

There are 3 types of reservoir for the continuing subsidence type basin , there are diapir reservoir , fault reservior , drape reservoir , and the source rock is apart from the reservoir , they are contact by fault ; and there are anticline reservoir , fault reservoir , incline reserve ir , mudstone reservoir under the denudation area , and the source rock is contact with the reservoir 以沉降為主要趨勢的盆地的油氣藏有底辟構造油氣藏、斷層油氣藏、披覆構造油氣藏，其烴源巖與油藏在空間上是分離的，并通過斷層相連；剝蝕區以下的油氣藏有背斜油氣藏或斷層油氣藏、向斜油氣藏及泥質巖油氣藏，其烴源巖和油氣藏可有密切的接觸關系。

From late - mesozoic to eogene , northern edge of mesozoic tarim basin became uplift gradually and the sedimentary range migrate to south . present u ' erdusi basin , yanqi basin , kumishi basin became uplift one by one and experienced strong deformation , denudation and reformation and some strata are denuded 中生代晚期到早第三紀，塔里木中生代盆地北緣逐步隆升，沉積范圍向南遷移，今尤爾都斯、焉耆和庫米什盆地范圍先后隆升，缺失沉積，并造較強烈變形、剝蝕等改造。

People ' s governments at various levels shall take measures to organize the masses to plant trees , protect forests and prevent fires , control plant diseases and insect pests in the forests , protect forest lands , checked up denudation and illegal felling of trees , and increase the forest coverage 各級人民政府應當采取措施，組織群眾植樹造林，護林防火，防治森林病蟲害，保護林地，制止濫伐、盜伐森林，提高森林覆蓋率。

Basin system is the united area of the deposition space and the denudation area . the evolution of the basin system can mirror the process of the related erogenic movement . the disintegration of a basin system indicates the end of one time of erogenic movement 沉積盆地系統是堆積空間與蝕源區的統一，盆地系統的演化反映出造山運動的歷程，一個盆地系統的瓦解是一次造山運動的完成，同時又形成了新的盆地系統。

3 . the variation of formation compression during uplift and degradation the uplift and denudation of basin have a greatly influence to the formation compression formed previously . the fashion of influence is related to the uniformity extent of degradation of the earth ' s surface 3盆地抬升剝蝕過程中地層壓力的變化盆地的抬升剝蝕對前期形成的地層壓力有重要的影響，影響的方式與地表剝蝕的均勻程度有關。

So , river capture can be taken as the time and space scale of geomorphologic evolution in quaternary in csmasr it can represent the process of river head wards erosion , expand of lincheng period denudation surface and the broken of yangping period denudation surface 認為河流襲奪是判斷地貌演進，即臨城期(第四紀)溯源侵蝕與仰平期剝夷面解體破碎的時空標尺，并據此探討了臨城期河流溯源侵蝕的時空格局。
