Sedimentary environment in benxi stage from east to west were respectively shallow - sea muddied continental shelf, barrier island, lagoon and tidal flat. most area in taiyuan stage was distributed by shallow - sea continental shelf, but the northern and southeastern part were scattered by clastic tidal flat and carbonate tidal flat. sedimentary environment in shanxi stage, in the middle and late shihezi stage was deltas and lake
馬5晚期研究區發育蒸發臺地相和局限臺地相；本溪期自東而西發育淺海泥質陸棚、障壁島、瀉湖及潮坪相；太原期大部分地區發育淺海陸棚沉積，北部和西南部則發育碎屑巖潮坪和碳酸鹽潮坪沉積；山西期和石盒子中晚期為三角洲和湖泊沉積環境；石盒子早期廣泛發育辮狀河三角洲和湖泊沉積。 -
On the basis of the analysis on the yangtze vole ' s disaster history and condition in dongting lake area, the influence of the lake beach ' s environmental evolution on the vole disaster is studicd in this paper. the rise of low - middle - level beach area causes the vole ' s population explosion, the reduction of high - level beach area forces the voles into the farmland during the flood season, and the emergence period ' s continual increase extends the vole ' s habitat areas and forces them to migrate into the farmland. the discarded dike provides a rest place halfway for the voles, which escape the flood, and the natural enemies of the voles, which are a natural barrier against the vole ' s population expansion, decreases. according to this study, the conclusions are put for ward as follows : after three - gorge project ' s construction it will produce great influences on the beach evolution in dongting lake area, leading to the changes of the vole ' s ecological environment situation and resulting in the vole ' s population changes which deserves attention
在分析洞庭湖區東方田鼠暴發成災史及災情的基礎上，研究了洞庭湖區洲灘演變對東方田鼠暴發成災的影響.研究認為，中低位洲灘出露面積不斷增大使東方田鼠種群迅速膨脹，高位洲灘出露面積減小造成汛期東方田鼠大量向垸內農田遷移;湖區洲灘冬春季連續出露天數增加延長了東方田鼠的繁殖期;汛期洪峰水位增高，洲灘大面積淹沒迫使東方田鼠大量遷向垸內;湖內廢棄湖堤為東方田鼠逃避洪水提供了中途休養之地;洲灘地抑制東方田鼠種群膨脹的天敵數量已大大減少.據此，本文指出，三峽工程建成后將對洞庭湖區洲灘演變產生重大影響，因而將改變東方田鼠種群生態環境條件，引起種群動態變化，值得注意 -
By studying the ancient barrier lake sediments, this paper mainly probes into the ancient climate evolution rule of more scale and less from twenty - two thousand to ten thousand years before present, diexi, minjiang river. moreover, influences to lower reaches of minjiang river is simply discussed because of die out of the ancient barrier. the using correlative theories in this thesis are mc chronology, sedimentology, isotope geology, environmental geology, geomorphology
本論文運用~ （ 14 ） c年代學、沉積學、同位素地質學、地貌學等學科的有關理論，通過對岷江疊溪古堰塞湖湖相沉積物的研究，採用沉積物碳酸鹽碳氧同位素等多環境代用指標，研究岷江疊溪地區距今約22千年10千年古氣候演化規律，討論了古堰塞湖形成演化過程與地質環境的相關性。 -
The implying environmental substitute indicators are carbonate carbon and oxygen isotopes and so on. the main conclusions drawn from this paper are as follows : ( 1 ) the ancient climate evolution, from twenty - two thousand to ten thousand years before present, diexi, minjiang river, is from dryness to wetness and can be divided into six phases and two periods by analyzing the ancient barrier lake sediments through multi - environment indicators, and its evolution cycle is three thousand years or so
主要得出以下幾點結論： （ 1 ）通過利用多環境代用指標對岷江疊溪古堰塞湖沉積物的綜合分析得出，岷江疊溪地區距今約22千年至10千年間的古氣候經歷了乾旱濕潤乾旱的演化過程，演變周期大約為3千年，並將其劃分為六階段、兩時期。 -
Furthermore, sixteen sedimentary subfacies are identified. respectively, the sedimentary subfacies are delta plain, delta front, prodelta, braided delta plain, braided delta front, braided prodelta, coastal lake, saucer lake, tidal flat, barrier island, lagoon, carbonate continental shelf, muddy continental shelf, open platform, local platform and evaporate platform
