Researches on the strata and their sedimentary facies in the Sandy Desert Area of China since 150000aBP., fossil verteberates, mollusks and sporo-pollen, and the remains of fossil man activities and the analysis resultes of grain-sizes, detrital heavy minerals, clay minerals, chemical elements and CaCO〓as well as the susceptibility values of the strata comprehensively show that the afore-named four sandy desert areas since that time, all had ever undergone intensely developing sandy desert processes but they did not all evolve towards uniform this environment, and the content and form between them were different.

通过对中国沙区15万年来的地层及其沉积相、古脊椎动物、软体动物化石、孢粉、古人类活动遗存与颗粒、碎屑重矿物、粘土矿物、化学元素、CaCO〓分析结果和地层磁化率值等的研究，表明从那时以来上述四大沙区都曾经有过强烈的沙漠发展过程，但这几个沙区沙漠环境的发展并不都是朝着一个方向，且几者间地质过程的内容与形式是不同的。

Darwin discussed about some anomalous forms in fresh water basins, which belong to the remnants of some interesting orders. Because these anomalous forms exhibit the anomaly of geographical distribution e.g. Ganoid fishes, or morphological anomaly such as Ornithorhynchus and Lepidosiren , they may be called living fossils. It is believed that Darwin presented the facts of the above anomalous forms, and used the term "living fossil" in order to further illustrate the subject of "Circumstances Favorable for the Production of New Forms Through Natural Selection" in Chapter IV. The term "living fossil" appears on page 486 again in the last Chapter, i.e. Chapter XIV "Recapitulation and Conclusion", where Darwin emphasized the significance of so-called "living fossils".

第一次在该书第四章"自然选择"（第107页）：为了在该章深刻阐述"通过自然选择产生生物新类型的有利条件"这一主题，达尔文谈到了淡水流域中残存着地理分布或形态上很异常的一些生物，如：硬鳞鱼、鸭嘴兽和美洲肺鱼，可以称之为"活化石"；第二次是在该书最后一章"复述与结论"（第486页），达尔文对"活化石"的作用进行了小结。

Weiyi linked to Banff, Jasper, Kootenay National Park and about the tiger, and Robson Hill, because of ACE Nibo Hill Park and Han Bo Pu Luo Wenxiu constitute a beautiful mountain landscape, where there are peaks, glaciers, Lakes, waterfalls, canyons and limestone caves.well-known fossil sites in the marine fossil mollusks, also found here.

"Clearly this new fossil would have been part of the food-chain, both as predator and prey," said Bloch, who co-led the fossil-hunting expeditions to Cerrejon with Smithsonian paleobotanist Carlos Jaramillo.

显然，如果能活到现在的话，无论是从作为捕食者还是被捕食者的角度来看，这种生物肯定是食物链中的一环。

On the basis of pollen analysis of surface sample in North China, polynomial function analysis method was applied to establish pollen climate response surface of Pinus, Betula, Quercus, Artemisia, Chenopodiaceae, Compositae, Picea, Ephedra, Gramineae in North China, therefore an easy and applicable method for reconstructing palaeoclimate and palaeoenvironment with data of fossil pollen was founded; Multi-analysis method was applied to analyse the principal elements of surface sample pollen in central Inner Mongolia Steppe, the assemblages of surface sample pollen in steppe area and its relationship with vegetation type were discussed with helps from spore-pollen analysis of a peat section in Chasuqi, Inner Mongolia and 〓C chronometer, fossil pollen data were obtained with high resolution on the peat section in Chasuqi. Vegetation succession and environmental changes since Holocene at resolution of 70 years were primarily reconstructed in south Mount Daqingshan and Plain Tumete. The changes in the area were copmared with those in the neighbouring areas during the same period. It was found that Holocene environmental change had undergone the following stages: cold-arid, temperate-wet, warm-wet, temperate-arid and cold-arid, and the climatical optimum period occurred in 5000-4100 aB.

本文在对中国北方表土花粉研究的基础上，采用多项式函数回归方法建造了中国北方松属、桦属、栎属、蒿属、藜科、菊科、云杉属、麻黄属、禾本科等的花粉——气候趋势面，从而为利用化石花粉资料直接恢复古气候、古环境提供了一种方便易行的方法；采用多元分析方法对内蒙古中部草原区表土花粉进行了主成分分析，探讨了草原区表土花粉组合的规律及与植被类型的关系；本文还应用孢粉分析方法，结合〓C测年技术，通过内蒙古中部察素齐泥炭剖面高分辨率的化石花粉数据，初步恢复了大青山山地南部及土默特平原地区分辨率为70年的全新世以来植被演替和环境变迁的状况，并与邻近地区的全新世古气候、古环境进行了对比研究，研究发现，本区域全新世古环境的变迁序列基本上可以与周围地区及华北地区进行对比，其环境变迁经历了凉干～温湿～暖湿～温干～凉干的变化，且气候最适宜期出现在5000～4100aB.P。
