蒙古栎

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。

The results showed that annual average temperature was the most important factor determining the occurrence of all species except for Quercus mongolica and Populus davidiana.

结果表明，除了山杨和蒙古栎之外，年均温是决定其它树种存在与否的重要因子。

The analyses result shows that tilia and mongolian oak are suitable for regeneration under the same arboreal species and other trees is suitable under different arboreal species.

对更新联结度的分析表明：紫椴和蒙古栎更适合于在本树种的树下更新，其它树种更适合于在非本树种的大树下更新。

E. , Pinus koraiensis, Quercus mongolica and Tilia will appear as new species. Fire disturbance has effects on forest biomass and its species composition and structure.

koraiensis、蒙古栎、椴树等树种；火干扰影响森林生物量及森林的物种组成和结构。

According the difference of plant community in Daqinggou Nature Reserve, the environment was divided into 7 kinds of habitats, they are Fraxinus mandshurica plant community, Quercus mongolicus plant community, Ulmus macrocarpa plant community, conifer community, lakefront plant community, paddy field plant community and grassplot plant community in sandlot.

按照植物群落的不同将保护区内的环境划分为7种生境，分别为水曲柳植物群落、蒙古栎植物群落、大果榆植物群落、针叶林植物群落、湖边湿地植物群落、稻田植物群落和沙丘草地植物群落。

Maximum value of ring-porous species-Fraxinus mandshurica , Fraxinus mandshurica , Phellodendron amurense, Quercus mongolica, semi ring-porous Juglans mandshurica, diffuse-porous Betula platyphylla, Tilia amurensis and non-porous Pinus sylvestris, Pinus koraiensis were as following: 430.53, 516. 36, 234. 00, 625. 93, 945. 83, 199. 49, 507. 93, 142. 43, 286. 21cm〓cm〓h〓 in diumal course during the growing season, The sap flow persisted after leaf senescence until the mid-October.

在生长季中环孔材水曲柳、水曲柳、黄波罗、蒙古栎树干液流密度日最大峰值分别为430.53（8月末）、516.36（9月中旬）、234.00（7月下旬）、625.93 cm〓cm〓h〓（9月初）；半环孔材胡桃楸为945.83 cm〓cm〓h〓；散孔材白桦和紫椴分别为199.49（9月上旬）、507.93 cm〓cm〓h〓（8月上旬）；针叶材樟子松、红松分别为142.43（7月中旬）、286.21cm〓cm〓h〓（7月下旬）。

It also can be app lied to simulate the dynamics of standing forest in Xiao Hinggan Mountains.Simulating forest with GISS 2xCO2 and GFDL 2xCO2 climate change scenarios indicated that forests in Xiao Hinggan Mountains are sensitive to climate change.There are very different responses of standing fores...

在GISS2xCO2 和GFDL2xCO2 气候变化情景下对现有林分的模拟实验显示：小兴安岭森林对气候变化具有敏感性；尽管森林对不同气候变化情景的响应明显不同，但基本趋势是一致的，即蒙古栎等阔叶树在森林中将占越来越大的比例

Results of pattern dynamic analysis are that Fraxinus mandshurica, Phellodendron amurense, Ulmus propinqua, Ulmus macrocarpa population patterns turined to random type from aggregative type in series of seedling, sapling, little tree, middle scale tree and big tree, because of higher tiller capacity, Quercus mongolica population pattern is still aggregative type in big tree stage.

格局动态的分析表明，水曲柳、黄菠萝、春榆、大果榆种群幼苗一幼树一小树一中树一大树分布格局由集群分布逐渐变为随机分布，而蒙古栎由于较强的萌生性，大树阶段仍为集群分布。

Results of pattern dynamic analysis are that Fraxinus mandshurica, Phellodendron amurense, Ulmus propinqua, Ulmus macrocarpa population patterns turned to random type from aggregative type in series of seedling, sapling, little tree, middle scale tree and big tree, because of higher tiller capacity, Quercus mongolica population pattern is still aggregative type in big tree stage.

格局动态的分析表明，水曲柳、黄菠萝、春榆、大果榆种群幼苗―幼树―小树―中树―大树分布格局由集群分布逐渐变为随机分布，而蒙古栎由于较强的萌生性，大树阶段仍为集群分布。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
