草原

Forests and grasslands are under effective preservation. The forest area in Tibet totals 7.17 million hectares and the stumpage, 2.084 billion cubic meters. The total grassland area amounts to 82.07 million hectares, of which 70.77 million hectares are usable.

西藏地区的森林和草原得到了有效保护，森林面积达717万公顷，活立木蓄积量20.84亿立方米，草原面积达8207万公顷，其中可利用草地7077万公顷。

South of the equatorial region is the tree-dotted grassland called the savanna.

赤道地区以南是一片树木稀少的草原，称为热带草原。

Thicketization of grassland is considered a deformation of a resource island under perennial grass tussock in conjunction with the formation of resource island under shrub-thicket.

结合半干旱草原中资源岛的形成机制，讨论了草原灌丛化作为多年生禾草草丛资源岛不断解体，同时灌丛资源岛不断形成的过程。

State-owned mineral resources and waters as well as forest land, mountains, grasslands, unreclaimed land and beaches owned by the state and those that are lawfully owned by collectives may not be sold, leased, mortgaged or illegally transferred by any other means.

国家所有的矿藏，水流，国家所有的和法律规定属于集体所有的林地，山岭，草原，荒地，国家所有的矿藏，水流，国家所有的和法律规定属于集体所有的林地，山岭，草原，荒地，滩涂不得买卖，出租，抵押或者以其他形式非法转让。

For those unfamiliar with the delightful prairie vole, it is a small rodent found in the grasslands of central North America.

草原田鼠的人们来说，它只是一种发现于北美中部大草原的小型啮齿类动物。

Whereas the horses on the prairie, who had never been such a creature, would think a monster had come into their midst and would be so scared that they would disperse with a whinny.

原因是这样的：那个来自内地的、长耳朵的善良动物来到草原上，看到了马群，以为见到了表亲，快乐地奔了过去；而草原上的马没见过这种东西，以为来了魔鬼，被吓得一哄而散。

Classification of steppe vegetation was developing principally in connection with the zonal division of the vast steppe areas of Russia.

草原植被的分类主要是在俄国广阔草原区的地带划分方面发展起来的。

Shannon-Weiner index、 Simpson index and Species evenness index were 2.13, 0.85 and 0.81 of frigid grassland, which were 1.36, 0.65 and 0.65 of upland brushy grassland.

高寒草原Shannon-Weiner指数、Simpson多样性指数和均匀度指数分别为2.13、0.85和0.81，山地灌丛草原则最低只有1.36、0.65和0.65。

During ～2.68-2.45 Ma, the vegetation was dominated by arbores, mainly Pinus, Chenopodiaceae and Artemisia, indicating a cold warm climate in the mountain region. During ～2.45-2.11 Ma, herbs increased rapidly and the climate became dry-cold, indicating the characteristic of the bushveld climate. During 2.11-1.49 Ma, the quantity and species of the herbs reached the culmination and the bush increased accordingly, showing that the climate became more and more arid. During 1.49-1.36 Ma, herbs declined slightly but pteridophytes increased relatively greatly, revealing a dry-cold grassland climate.

约在2.68～2.45Ma期间，植被以乔木为主，主要为松、藜、蒿，属山地寒温气候；约在 2.45～2.11Ma期间，草本植物迅速上升，气候变得干旱寒冷，显示出灌木草原气候特征；在2.11～1.49Ma期间，草本植物数量和种类达到之最，灌木相对增加，也显示气候进一步趋于干旱；在1.49～1.36Ma期间，草本植物有小幅下降，但蕨类植物增加幅度较大，显示了干冷草原气候特征。

The fossil pollen date showed that vetetation changed from desert steppe dominated by Artemisia in early Holocene, though desert dominated by Chenopodiaceae at 9.0-6.3 ka, desert steppe dominated by Artemisia at 6.3-2.5 ka, to desert dominated by Compositae at 2.5-1.0 ka and Chenopodiaceae after 1.0 ka.

青土湖剖面孢粉分析结果显示，该区9.0ka之前为蒿属为主的荒漠草原，9.0～6.3ka藜科为主的荒漠，6.3～2.5ka蒿属为主的荒漠草原，2.5～1.0ka菊科为主的荒漠，1.0ka之后为以藜科为主的荒漠。

I can not make it blossom and suits me

我不能让树为我开花

When temperatures are above approximately 80 °C discolouration of the raceways or rolling elements is a frequent feature.

当温度高于 80 °C 左右时，滚道或滚动元件褪色是很常见的特征。
