沙漠化

Sandstorms in China appear to have increased in recent years as a result of "desertification".

在中国，由于沙漠化的原因，沙尘暴在最近几年有所增加。

Desertification is one of the most serious environmental, social and economic problems in China.

沙漠化是我国面临的最严重的生态环境问题之一，利用市场机制防沙治沙是治沙事业发展的必然趋势。

Now number four: we have to stop desertification. We can.

第四，我们必须遏止土地沙漠化，我们可以做得到的。

All in all, the desertification of the study area is developing With growing areas and level.

总之，研究地区沙漠化是一个发展的过程。

A number of solutions have been tried in order to reduce the rate of desertification and regain lost land.

人们已经尝试了很多方法来降低土地沙漠化的程度和恢复已失去的土地。

The desertion of this area helped to preserve this type of dog as we know it now.

这地区的沙漠化帮助了中亚牧羊犬的保存和繁衍，使我们今天还能见到它们。

Furthermore, people always cut down trees and dig up grass.

在我看来，沙尘暴是由沙漠化和温室效应引起的。

This is a process that happens when land becomes desert because of climate changes and because people cut down trees and dig up grass.

这一进程是由于气候变化以及人们肆意砍伐森林和破坏草皮从而导致土地沙漠化的情况下发生的。

Because they do disafforestation, opening up grasslands, reclaiming field from the intertidal zone, finally cause seriously ecology losing balance and destroying, forest decrement, soil erosion serious, climate worsing, desert broadening the scope, drought and flood harm frequently appearing, all these makes whole ecology going to worse and ...

因毁林开荒、开垦草原、围垦滩涂，结果导致生态平衡失调和破坏，造成森林减少、水土流失严重、气候恶化、沙漠化扩大，洪旱灾害频发，使整个生态环境趋于恶化，最终影响到人类自身的生存。本文列举了巴州地区土地开发的现状，分析了土地开发对生态环境造成的影响，并提出了生态环境保护对策与建议。

Such carastrophes of marshy ground as grassland degeneration,lake dried up,soil hardended and impervious,groundwater lowering and desertification are increasingly serious in Zoigê and Hongyuan,west Sichuan which is attribusable to disrupture of local aquifers and unreasonable groundwater exploiting.

以若尔盖、红原为代表的四川西部湿地，近数十年来草场退化、湖泊干涸或缩小、软土硬结、地下水位下降、沙漠化等地质灾害日趋严重。其水文地质原因是局部含水层和水盆结构被破坏，以及不合理的抽取地下水。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
