  1. The author presume the original physiognomy of jiuzhai valley, and acknowledged changhai valley was a surface - water with uniform waterpower, the rize valley was a branch of it but the inequality rise of lithosphere, the deposit of earthquake landslides debris flows and falling or glacier blocked the river - way, furthermore, the flow water with high content of ca ( hco3 ) 2, so tufa dyke formed and evolvement the present dyke of lakes the present physiognomy formed on the base of those 2

    由於地震、滑坡、泥石流引起的堆積物和冰川作用形成的冰磧物堵塞河道，再加上構造運動造成地殼的不均勻抬升，九寨溝的這種獨特的地質環境以及高含ca （ hco _ 3 ） _ 2的巖溶水流作用下，為caco _ 3沉積創造條件，沉積的caco _ 3加高、連接最終形成灰華堤壩，使湖泊的形成成為可能。
  2. This result lays a solid foundation for the research. 2. based on the study of petrology facies, facies association and sedimentary sequences, the sedimentary processes and systems are established. they consist of debris and hyper concentration flow deposits, channel deposit of braided and meandering streams, and alluvial fans, floodplains, fan - deltas and lacustrine turbidities

    根據巖相、相組合以及沉積層序的研究，確立了研究區的沉積作用類型和沉積體系，它們包括碎屑流和超濃縮洪流沉積、辮狀河河道沉積，以及沖積扇沉積、洪泛平原沉積、扇三角洲沉積和湖相濁流沉積。
  3. Abstract : the authors discuss roundly source of loose earth fo r impact - deposit debris flow to develop taking pingchuan debris flow, one of the quite typical impact - deposit debris flows in southwest sichuan province ， as an example in this paper. on the basis of detailed investigations in - situ, geotechn ial testing in lab and theory analysis, all results indicate obviously that moder ate and bulky loose earth in giant debris flow situating in southwest sichuan mo untainous area are main institute, whose tribulation are consistent with landform s. loose earth locating in mid - forepart catchment are quite unstable, so often be comes main source of loose earth of debris flow. formation of loose earth is cont rolled principally by geologic and geotechnical environment while human actions is the secondary factor for loose earth to form. in many times, human actions prov ide loose earth through loose earth stability

    文摘:本文以極具典型的平川泥石流為例比較全面的分析了沖淤變動型泥石流的物源問題.根據現場調研及室內巖土分析進行的研究成果顯示，川西南高山深谷地區的大型泥石流溝中的鬆散土體以中、粗粒段為主，其分佈與地形密切相關；位於泥石流溝中、前部位的鬆散土體的穩定性最差，是補給泥石流的重要物源；鬆散土體的發育主要受控于地質及巖土環境，人類活動只能影響鬆散土體的穩定性
