The late ordovician - silurian - devonian - early carboniferous stratigraphic division and correlation, including the chronologic correlation of the donghe sandstone, which are the old great difficult key stratigraphic problems interfering with the development of the oil and gas exploration in the tarim basin, are synthetic studied by systematically applying chemobiostratigraphy. several important relevant stratigraphic boundaries are recognized, and the donghe sandstone is attributed to the frasnian, late devonian. the results of the study in particular proves that chemo - biostratigraphy has great significance and is a practical tool for high resolution stratigraphic division and correlation, especially for the region and or the bed with rare fossils
首次系統應用化學生物地層學對長期遺留的嚴重阻礙了油氣勘探開發步伐的塔里木盆地重大疑難地層問題：晚奧陶世志留紀泥盆紀早石炭世地層劃分對比和東河砂巖時代等進行了綜合研究，釐定了幾條重要的相關地層界線，並將東河砂巖的時代確定為泥盆紀晚泥盆世弗拉斯期。這些研究成果表明，化學生物地層學對高解析度地層劃分對比尤其是對在化石缺乏地區和層段進行地層劃分對比工作有重要的意義和實用價值。 -
The water current flows over the top of the dentoid baffle to the hydraulic jump as additional momentum. while it is cooperated with a stilling basin, the flowing condition emerged in the basin may be improved greatly and the length and downstream water depth required by the basin can be decreased to a great extent. such an appliance may be also used to solve the problems of insufficiently dissipating water flow energy and aerating flow, which are often faced with those hydraulic engineering constraction as acted by high waterhead, great specific discharge and low froude number
本文通過齒墩頂部的擴散水舌所形成的附加射流，從上部射入水躍，即可改善消力池內的水流流態，又可降低第二共軛水深，減小水躍長度，增進水躍消能效果，同時還能解決大單寬、低佛勞德數條件下摻氣和消能不足的問題，試驗證實它是一種安全、經濟的消能工。 -
The others showed partly decreased, but the degradation of vegetation were obviously in lower reaches of tarim and cherchen river ; in the mountain area of southern xingjian, the forest area were increased, and the others decreased ; in northern xingjian, both the mountain and the plain area increased. they showed the decrease of desert and the increase of oasis ; the change of vegetation cover in the hexi corridor - alax desert were not obviously ; but in chai - damu basin, the area of desert and low cover grassland increased, the others vegetation decreased, especially in the high cover grassland. that showed the great degradation of ecosystem, and the most of degradation was shown in the north hillside of the arjin mountain and qi - lian mountain
而從各個分區來看，情況不盡相同:南疆地區平原區綠洲面積擴大，荒漠面積基本不變，其他類植被面積不同程度縮小，而在塔里木河下游、車爾臣河下游植被退化;南疆山地森林面積略有增加，其他類植被面積略有縮小;北疆的平原區和山區的植被狀況均有改善，表現為荒漠面積縮小，綠洲面積增加;河西走廊一阿拉善地區總體變化不大;但是柴達木盆地的荒漠面積、低覆蓋度草地增加，其他類植被，尤其是甚高覆蓋度植被（草甸）的面積縮小，表明該地區的生態環境退化，而退化表現的主要地區在環柴達木盆地的阿爾金山和祁連山的北坡。
