无覆盖的

The testing results indicate there is a visible regulating effect in soil temperature with crop residue cover.

试验结果表明，残茬覆盖对土壤温度有明显的调节作用，5、10、15、20 cm各层有覆盖相对于无覆盖分别增温1.5~2.1℃、0.9~1.2℃、0.2~0.9、0.4~0.8℃，随着土壤层的加深，覆盖对土壤温度的调节作用越来越小。4月20日至6月15日前后，随着覆盖量的增加，土壤温度开始升高，但覆盖量增加到一定程度后，土壤温度将下降，在6月20日以后，随着覆盖量的增加，土壤温度逐渐降低，其中30%覆盖相对于无覆盖，降低1.1~1.5℃，50%~80%覆盖降低2~3.6℃，而表土层降低幅度最大，沿深度方向幅度越来越小。

The surveyed results show that as compared to the uncovered vegetation area, the existence of soil microbiotic crusts in the Tengger Desert region significantly increases the diversity and abundance of insect species, especially the diversity and abundance in the quadrats mainly covered by moss and lichen crusts are significantly higher than those in the quadrats mainly covered by cyanobacteria and algal crusts.

结果表明：与无结皮覆盖的植被区相比，生物土壤结皮在地表的覆盖显著地增加了昆虫的多样性和种的丰富度，其中以苔藓和地衣为主的结皮覆盖的植被样方中昆虫种的多样性和丰富度显著地高于以蓝藻和藻类为主的结皮样方。

The stillness of the morning is impressive. The floor creaks under our feet as we move toward the window to look abroad through some clear space over the fields. We see the roofs stand under their snow burden. From the eaves and fences hang stalactites of snow, and in the yard stand stalagmites covering some concealed core. The tree and shrubs rear white arms to the sky on every side; and where were walls and fences, we see fantastic forms stretching in frolic gambols across the dusky landscape, as if Nature had strewn her fresh designs over the fields by night as models for man's art.

安静的早上总是令人难忘，我们踏着吱呀作响的地板走到窗前，站在一块无雪的地方来观望广阔的田野，我们看到屋顶都覆盖着皑皑白雪，屋檐和篱笆上挂满了冰棱，院子里的东西也被白雪覆盖了，像石笋一般，无从知晓里边究竟是什么，大树小树向四方伸展着它们洁白的枝丫；而在昏暗的大地上，院墙和篱笆以不可思议的形式向各处伸延，像是在愉快的跳跃，仿佛一夜的功夫，大自然就重新设计了一幅美景，供人类来临摹。

On bright, calm days they lie in thousands on the now darkening water, mostly yellow flotillas of poplar, floating continuously down from great trees that themselves shake in the windless air with the sound of falling water , but on rainy days or after rain they seem to swim or be driven away, and nothing remains to break the surface except the last of the olive-yellow lily pads that in high summer covered every inch of water like plates of emerald porcelain...

当风和日丽时，无数的树叶浮在已经变暗的湖水上，大部份都是白桦叶子，他们一批一批，像黄色的小小扁舟，不断地从高高的树上飘落下来，在无风的空气中轻轻地晃动着，发出如同流水而下的声音。但是在下雨的时候，或者雨过之后，那些浮在湖面上的落叶，仿佛鱼儿一样都游走了，又像是被不知什么驱赶一空，湖面上除了最后的几片黄绿色睡莲叶子，再无一物，而在盛夏里，那些睡莲叶子，如同翠绿晶莹的瓷盘，覆盖着每一寸湖面。

在晴朗无风的日子里，树叶成千上万聚集在颜色转暗的湖面上，这黄色的如同小舟一般的落叶--大多数是白杨树叶---纷纷从那些即始无风也抖动不已的高树上飘落下来，淅淅沥沥，仿佛水声，但是遇上雨天，它门又漂得无影无踪，于是，除了那在盛夏时节宛如盏盏翠莲把湖面覆盖而如今只是一片橄榄黄的睡莲残叶
