The origin and evolution of land plants was an important event in the history of earth life and has affected all other lives on the earth and global environment. during the past two decade, the new discoveries of fossil plants microfossils and megafossils from the mid - ordovician through all silurian to the lower devonian improved knowledge of the origin of land plants, provided a time framework of the basal groups for the land plants and the early evolution diversity of vascular plants. three new plant based epochs have been recognized. on the other hand, molecular sequence studies have provided insights into the phylogeny and early branches of land plants. a phylogenetic tree has been established by the joint of a study of comparative morphology and gene sequences. this paper summarizes recent advances and new knowledges, comments on the phylogenetic studies based on the cladistic analysis
陸生植物的起源和演化是地球生命中的重大事件,它影響到地球上所有的其他生命和全球環境。在過去的20年中,從中奧陶世歷經整個志留紀至早泥盆世的巖層中,化石植物微化石和大化石的新發現改變了人們對陸生植物起源的認識,並且為陸生植物和維管植物早期演化分異提供了基部類群分化的時間框架。據此人們識別出地史中的3個陸生植物的時代:始胚植物時代始維管植物時代和真維管植物時代。The thesis analysises the typical model profile and the special rock profile of wudaoliang group of miocene epoch in hoh xil basin. and be used the biocalcarenite with the marl rock take the marker bed of wudaoliang group
論文對可可西里盆地中新世五道梁群的典型剖面和特殊巖性剖面進行了分析,並以泥灰巖和生物碎屑灰巖作為五道梁群的標志層。( 4 ) the formation and growth of structural traps and stratigraphic - unconformity traps in the area is controlled by three compressive stages of silurian - devonian, late permian - tertiary and oligocene - quaternary ; non - structural and compound traps mainly grew in the early paleozoic. structural traps mostly grew in the late paleozoic and the cenozoic and mostly grew on the north and south belts ; non - structural traps mostly grew in the northern area of the hetian concave. most traps in the area formed or typed at last in the himalayan episode, dispersed on the north and south belts
( 4 )研究區構造與地層不整合圈閉的形成和發育受志留-泥盆紀、晚二疊世-第三紀、漸新世-第四紀三個擠壓階段的控制;早古生代主要發育非構造圈閉和復合圈閉,晚古生代和新生代則主要發育構造圈閉:構造圈閉主要發育在南北兩帶上,其次為中帶;非構造圈閉主要發育在和田凹陷以北的地區;研究區內大多數圈閉是喜山期形成或最終定型的,在南北兩帶都有分佈,而海西期圈閉主要分佈於研究區中帶瑪南構造帶處。Pliocene micromammalian biostratigraphy of nihewan basin, with comments on the stratigraphic division
