主要介绍了磷灰石裂变径迹分析法、沉积波动过程分析法和宇宙成因核素分析法等3 种恢复和计算地层剥蚀量的新方法。

During the study, in order to decrease the complexity, the article simplifies the geomorphic process, defines the ideal state, and, according to the geomorphic principle, reasons out some of the 4-Dimensional Geomorphic Mathematical Sub-Models that include the 4-Dimensional Tectonic Geomorphic Mathematical Model, the 4-Dimensional Depositional Geomorphic Mathematical Model, and the 4-Dimensional Denudate Geomorphic Mathematical Model.

在研究过程中，为了减低复杂程度，简化了地貌过程，规定了理想条件，并根据地貌学原理推导了部分理想条件下的四维地貌数学模型，分别是四维构造地貌数学模型、四维沉积地貌数学模型和四维剥蚀地貌数学模型。

Base on comparison with the remote sensing data in 1982 and 2000 and field investigation, the results of land cover and land use change were obtained by the method of landscape analysis. Ten types of land use were identified: riparian woods, riparian shrubbery, desert shrubbery, desert grassland, river-way and water area, salinised land, town, Gobi, shift sand dune, denudative upland. The results show that,(1) there were obvious changes in land cover structure.

根据黑河下游额济纳绿洲土地生态分类，利用1982年与2000年2期TM遥感数据对比和野外实地调查，采用景观生态空间分布格局分析方法，分为河岸乔木林、河岸灌草林、荒漠稀疏灌丛、荒漠稀疏草地、河道与水域、盐碱化土地、城镇、戈壁、流动沙丘和剥蚀地山丘陵，从各类土地分布面积变化和类型转移趋向与幅度两个方面，分析了额济纳绿洲20年来土地覆被变化。

In the river valley region,discal phenomena of drilling cores and laminated exfoliation of surrounding rock in the exploration tunnels are obvious.

拉西瓦水电工程坝址区为高山峡谷地貌，受地质构造应力、自重、地表剥蚀和河流侵蚀卸荷等多因素影响而赋存有高地应力，河谷区钻孔岩芯饼化与探洞片状剥落现象明显。

The Danxia Landform in Jiangxi Province was formed mainly in red beds in the upper Cretaceous. It is generally the by-product of the new neotectonic movement's intermittent uplift companied with faults' downcut, running water's scouring, weathering and degradation.

江西省丹霞地貌主要发育于晚白垩世红色岩层中，是晚第三纪以来新构造运动间歇性隆升、断裂切割、流水冲刷和风化剥蚀的产物。

Erodible soil fractions are usually dislodged from projections and trapped in depression.

可冲蚀土壤部分经常从凸出物剥蚀并降落于洼地。

In Floreal[34] this enormous thicket, free behind its gate and within its four walls, entered upon the secret labor of germination, quivered in the rising sun, almost like an animal which drinks in the breaths of cosmic love, and which feels the sap of April rising and boiling in its veins, and shakes to the wind its enormous wonderful green locks, sprinkled on the damp earth, on the defaced statues, on the crumbling steps of the pavilion, and even on the pavement of the deserted street, flowers like stars,dew like pearls, fecundity, beauty, life, joy, perfumes.

到了花开的季节，这一大片树丛草莽，在那铁栏门后四道墙中随意寻欢，暗自进行着普遍的繁殖，并且，几乎象一头从曙光中嗅到了漫山遍野求偶气息的野兽，感到暮春三月的热流在血管里急走沸腾，猛然惊起，迎风抖动头上披纷茂密的绿发，向着湿润的地面、剥蚀的雕像、楼前的破落台阶直到荒凉的街心石，遍撒着繁星似的花朵、珍珠似的露水、丰盛、美丽、生命、欢乐、芬芳。

Based on the high resolution environment magnetism analysis and geomorphy, the following conclusions and new findings are revealed

通过对晚新生代沉积地层高分辨率的环境磁学研究可进一步捕捉重大的环境变化事件，测定其形成的年代及变化，并推测剥蚀面形成和抬升的时间以及确定这些层状地貌形成的时代，进而推演六盘山和青藏高原构造隆升的历史。
