草地

With a study of plant community succession on 5 stocking rates,herbage utilizational efficiency and risk-benefit balance,it is suggested the sustainable development should follow:(1)no degradational principle of rangeland,(2)the maximum herbage utilizational efficiency,(3)the risk-benefit balance,When stocking rate was no more than 2.67 sheep/hm2,the proportion of grasses and plant biodiversity index and evenness were increased based on Artemisia frigida and short-grass rangeland.

草地畜牧业可持续发展的三大生物经济原则为草场不退化原则、最大生物学效率原则和风险-利润权衡原则：(1)草场不退化原则。在冷蒿小禾草退化草原上，暖季期间1.33～2.67羊/hm\+2的放牧率下可使其发生恢复演替，禾草的比例增大，植物多样性指数和均匀度指数均有所提高，从而达到利用式改良的目的；相反，若继续重牧或过牧，放牧绵羊喜食的植物种类将进一步减少，植物多样性指数也有所降低。

Aeneas on the other side called to his comrades, looking towards Deiphobus, Paris, and Agenor, who were leaders of the Trojans along with himself, and the people followed them as sheep follow the ram when they go down to drink after they have been feeding, and the heart of the shepherd is glad- even so was the heart of Aeneas gladdened when he saw his people follow him.

在战场的另一边，埃内阿斯亦在召唤他的伙伴，双眼扫视着德伊福波斯、帕里斯和卓越的阿格诺耳，和他一样，都是特洛伊人的首领。兵勇们蜂拥在他们身后，像羊群跟着带队的公羊，离开草地，前往水边喝饮，使收入眼见心喜――就像这样，埃阿斯心中充满喜悦，眼望着大群的兵丁，跟随在他的身后。

In these photographs, you can see Botticelli's "Primavera" and "The Birth of Venus", Manet's "Dejeuner sur l'Herbe" and "Olympia", Ingres's "La Source", Renoir's "Les baigneuses", and countless other classical images. And yet all have been rendered in slightly unrecognisable form, existing in parasitic relation to the originals.

在王庆松的照片中，他借用了很多经典，或是经典画面，或是经典故事，比如《泉》、《中国之家》、《罗曼蒂克》、《思想者》或《瑶池相会》等等，在这些照片中，你可以看到波提切利的《春》、《维纳斯的诞生》，马奈的《草地上的野餐》、《奥林匹亚》，安格尔的《泉》和雷诺阿的《大浴女》，无数经典形象在这些照片上随处可见，然而都被他处理出一些令人不适的偏差。

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。

The grass will depasture 100 cattle .

该草地可放牧一百头牛。

But they face a problem: invading "river crabs" that are devouring their grassland.

但是他们面临了一个问题：入侵的&河蟹&吞食它们的草地。

The sequence of Diurnal change of WUEph of different plants in lawn community is: Geranium sibiricum, Leymus secalinus, Potentilla supine., Viola prionantha, Poa pratensis and Potentilla anserine:The sequence of physiological drought resistance of weeds and turf in lawn community is: Poa pratensis, Digitaria ischaemumjotentilla supine, Potentilla anserine, Viola prionantha, Geranium sibiricum and Inula britanica.

草坪群落中不同植物的水分利用效率日变化均值大小为：鼠掌老鹳草＞赖草＞铺地委陵菜＞早开堇菜＞草地早熟禾＞鹅绒委陵菜。

Sometimes, I sat on the grassland, gazing into the sky and dreaming of you, stepping downby a seat in the imperial carriage, helping me stand up from dust and arranging me by your seat.

有时我坐在草地上凝望天空，梦想着你从车辇的座位上走下来，把我从尘埃中扶起，并安置在你的座位旁。

And Echinochloa crusgalli L. were studied. Both of the aqueous extract from aerial part and root of T. repens inhibited the germination rate of weed seeds, root activity and respiratory rate, and the activities of superoxide dismutase peroxidase and catalase of germinating seeds; enhanced the activity of peroxidase and the content of malondialdehyde.

结果表明，白三叶草地上部分水浸液和根部水浸液显著抑制苘麻和稗草种子的发芽率，降低了杂草种子萌发过程中超氧化物歧化酶，过氧化氢酶的活性，抑制了杂草种子萌发过程中的呼吸速率，根系活力，明显提高了杂草种子过氧化物酶活性和丙二醛的含量。

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。
