The result of factor analysis can provide the changes of relative precipitation and temperature variations. In trace elements, Cu, As, Zn, Pb and Ni were apparently enrichmented in soil layers and are sensitive to climatic changes. Carbon isotope is more sensitive to climatic changes than that of oxygen isotope in loess stratigraphy. The heavy mineral are varified in the loess stratigraphy, but their content differences between loess and palaeosol is little. Though the palynologic analyses results reveal that pollens and spores are fewer in the loess stratigraphy, they differ greatly in loess layer and palaeosol layer not only in species but also in types, i. e., the pollens and spores indicating warm and moist climate, such as Lles, Podocarpus, Polopydium, Pteris grerilliana Wall, Pterocarya and Juglans appear in palaeosol layers, while those indicating cold and dry climate such as Ephedra, Artemisia, Chinopodiaceae, Picea and Abies exist mainly in loess layers. The pollen content of broad-leaved tree mainly consisting of Pterocarya is up to 60% in palaeosol 〓, while the content of Ephedra is more than 50% in 〓 loess layer, showing that the environment differed greatly when 〓 and 〓 were formed.
当然,常量元素氧化物的组合因子分析结果可提供相对降水与相对温度在剖面的变化,因而来反映气候状况更为理想;微量元素中Cu、As、Zn、Pb与Ni在成土过程中富集明显,亦较好地反映了气候变化;稳定同位素中的碳同位素比氧同位素更能敏感记录气候的变化;研究区黄土地层中重矿物种类较多,但黄土层与古土壤层中含量差异不大;孢粉分析结果揭示,尽管研究区黄土层中孢粉总量相对较为贫乏,但黄土层与古土壤层中孢粉种属相差较大:在古土壤层内出现了指示相对暖湿环境的冬青属、罗汉松属、水龙骨属、林下凤尾蕨、枫杨、胡桃等植物孢粉,而黄土层中麻黄、藜科、蒿属及冷杉、云杉含量较高。

The results showed that grassland and farmland were the main land use types of research area with obvious reciprocal transformation. Grassland was mainly transferred to farmland in 1975-1990. Farmland was chiefly converted to grassland, and grassland tended to increase in 1990-2004. The landscape diversity in the study area rose with the contagion index decreasing and fragmentation degree being intensified during 1975-2000. The advantageous patches maintained good connectivity with the increasing patch cohesion index and the decreasing landscape fragmentation during 2000-2004. The change of human interference intensity played an important role on the variation of land use structure. Land use intensity was mainly affected by the changes in population as well as national land use policies. In the following 20 years, the agriculture land area would tend to decrease, the grassland and unused land area would have a slight reduction by contrasting the increasing the forest land area notably.
结果表明,近30 a来,草地和农业用地面积在该研究区占居主导地位,并且它们之间发生着明显的相互转化。1975-1990年,草地主要向农业用地转移,1990-2004年农业用地主要转化为草地,草地面积增加;1975-2000年,研究区景观多样性升高,蔓延度指数下降,破碎化程度加剧;2000-2004年景观内优势斑块具有了很好的连接性,聚集度增大,整体景观格局破碎化程度降低;人为干扰强度的变化对土地利用结构的变化具有重要作用,土地利用强度主要受人口数量以及国家土地利用政策的影响;在未来20 a间农业用地面积会继续减小,草地、未利用土地面积将有小幅度降低,林地面积会显著增加。

Steel moment-resisting frames with welded beam-to-column connection were traditionally regarded as having excellent performance, and widely adopted in steel constructions, but this opinion changed after the 1994 Northrige earthquake and the 1995 Hyogoken-Nanbu earthquake. These earthquakes also arouse engineers to resurvey the behavior of end-plate connections. It is well known that end-plate connections have definite flexibility, which can increase damp, prolong period, and decease swing of structure. So it can reduce the damage, and is one of the best choices for resisting earthquake.
