It was observed that the influence of bud and its position on the healing process of grafting unions using hardwood sectioning method, and found that:(1) bud of a scion and its position to the graft unions have no influence on callusing formation of the isolation layers, and the early differentiation of cambia;(2) a scion bud closer to the grafting union would promote the formation of more compacted callus cells and the earlier formation of callus bridges;(3) conduit differentiation in grafting unions of lower-bud scions was later than that of other treatments.

利用滑动切片法对芽子有无及芽位对嫁接愈合过程的影响进行了观察，发现：(1)接芽有无及芽位对隔离层及愈伤组织形成和形成层的早期分化没有影响；(2)芽或去芽的芽位距接口近，可以促进愈伤组织的紧密连接，即愈伤组织桥的形成；(3)低位芽枝嫁接体中导管分化较晚，而其它处理导管的分化几乎是同时发生的，而且导管首先出现于愈伤组织薄壁细胞中。

Oxygen and carbon isotope of the carbonate sediments separately indicate lake waterδ~(18)O andδ~(13)C_,δ~(18)O indicates the volume of the input water which is a good index of Lake water level changes;δ~(13)C_ indicates the degree of the exchange between the lake and the atmosphere and indirectly indicates the ice cover time controlled by the temperature.3. Environmental changes in Lake Sugan drainage area during the past 2670 years reconstructed by mul-index synthesis analysis indicates that during

沉积物碳酸盐氧、碳同位素分别反应了湖水的δ~(18)O和δ~(13)C_，δ~(18)O指示湖水体积变化，是湖泊水位变化的良好指标；δ~(13)C_则指示了湖水和大气的交换程度以及入流水量的大小，间接指示了温度控制下的冰封时间长短。3、多指标综合分析重建的苏干湖流域晚全新世近2670年来的环境变化显示，苏干湖2670年来流域持续变干；出现截然不同的两个大的阶段，即

This paper discusses the research carried out on the Lake Sugan, in the northern margin of Chaidam Basin. The climate and environmental changes in Lake Sugan drainage area over the past 2670 years were studied using the varve dating of the well preserved lamination sediments in core SG03I taken from the center of Lake Sugan, the study of varve formation in modern lake system and modern process study of carbonate and oxygen isotopes of the water within the drainage area, and according to the main index of the stable isotopes of carbonate sediments synthesized other index analysis.

本文以柴达木盆地北缘苏干湖为研究对象，通过对湖泊中心位置SG03I孔保存完好的纹泥沉积物岩芯进行年代学研究，对湖泊现代沉积过程及碳酸盐、流域水体同位素进行现代过程研究，以沉积碳酸盐稳定同位素指标为主，结合其它代用指标的综合分析，探讨苏干湖流域近2670年来的气候与环境变化，综合区域其它记录对苏干湖流域晚全新世气候变化的驱动机制进行探讨，获得如下认识：1、柴达木盆地北缘苏干湖若干钻孔岩芯发现，水深大于3.0m的沉积物均具有裸眼可分辩的由深色层和浅色层组成的纹层层理。

The sand dunes analyses data have shown they mainly consist of well sorted, symmetry skewness and find sands, and the kurtosis peak is narrow or very narrow. There are abundant impacts of mechanic process on the surface of quartz grains. The traces of eolian process often superpose on the traces stamped by river and beach processes. The dish--shaped concavities and mechanic pits are the most common surface textures, but the barchan concavities and curved grain edges are indicated the marks by eolian environment. The heavy minerals assemblages of coastal dunes are dominated by relatively high specific gravity which have stable chemical properity suggesting the mordern high dynamic environments of coast area. The depositional structures of coastal dunes are typified by corss--bed sets composed of steep foreset laminates and gentle windward dipping sets. It also contains some shell fragments and strong worn foraminiferal tests that are impossibly found in inland desert. On the other hand, the sandy deposits of the continental shelf of East China Sea are with wide range of grains, and the depositional pattens are quite complicated.

海岸沙丘是晚全新世以来相对稳定的海平面背景下的海岸带风成堆积，其沉积特征是以细沙为主，分选好，搬运方式以跃移占绝对优势，偏度上近对称，峰态窄到很窄；石英颗粒表面机械作用形态丰富，风成作用形态叠加于河流和海滩过程形态之上，碟形坑和撞击麻点是最为常见的表面形态，而新月形坑和曲脊是其指示性的特征标志；沙丘沙重矿物以化学性质稳定、比重较大的种类为主，反映了海岸带目前的高能动力环境；海岸沙丘沙的沉积构造以高角度前积层和低角度顶积层组成的交错层理为典型特征，同时还含有少量内陆沙漠所没有的少量贝壳碎屑和强烈磨损的有孔虫壳体。

Among above deformation, the thrust-fold structure formed in Triassic established the E-W trend framework controlling the distribution of the late compressive settling. The NNE-NE trend obduction zone and regional folds is contributed to effect of Tethys tectonic region superimposed by Paleo-Pacific tectonic region.

其中三叠纪挤压变形产生的冲断—褶皱构造，奠定了本区中生代近东西向构造格局，并控制后期挤压坳陷型盆地的的空间展布规律；晚侏罗世早期挤压形成的北北东—北东向逆冲推覆构造带和区域性褶皱是特提斯构造域与古太平洋构造域共同叠加的结果。

Results The diagenetic grade of Permian rift basin was quite high, and the mechanical compaction resulted in the great loss of the original pore. The eodiagenesis and telodiagenesis were important to the reservoir, and fractures were the dominant hydrocarbon migrating pathway and accumulating space; In Triassic-Paleogene Formation, mechanical compaction was as important as pressolution, and the most original pore was preserved. The exodiagenesis stage of late hercynian movement, indosinian movement and Yanshan movement played the vital role in the diagenetic evolution and hydrocarbon migration and accumulation of the basin. The argillaceous dolomite and algal dolomite discaved in Permian, which were formed probably by hybrid process in high salinity lake which had the fresh water interfused in.

结果 二叠纪裂谷盆地的成岩强度大，以机械压实作用为主，原生孔隙丧失多且早，晚期成岩作用较重要，裂缝是油气运聚的通道和空间，可出现次生孔隙发育带；三叠纪－古近纪拗陷盆地的成岩作用表现为机械压实和化学压实作用并重，原生孔隙多被保留；晚海西、印支、燕山运动等表生成岩阶段对该区的成岩演化和油气运聚起到重要作用；二叠系中特征的泥云岩和藻云岩可能是在有淡水注入的较高盐度湖泊中经混合作用而形成的。

Based on tectonic evolution and magmatic activity of the Junggar basin and its surroundings,it is recognized that the ocean-continent transformation occurred at the end of the Early Carboniferous,and that a rifted trough of Middle-Late Carboniferous developed because of post-orogenic extensional collapse;(2)the prototypes of Permian-Early Pleistocene basins...

尽管油气地质勘探工作已达50多年，积累了丰富资料，但对于盆地原型和构造演化的看法仍然存在很大的分歧。分歧点主要是：(1)中、晚石炭世盆地的性质，究竟是属于残留海、海相前陆盆地还是属于伸展裂陷槽？(2)二叠纪至古近纪盆地

Along with Tajik Basin and the Southwest Southwest Depression of Tarim Basin, Alay Basin was one of the remnant basins on the north rim of the Tethys during the Late Triassic to Paleogene, it became a peripheral foreland basin in Miocene.
