The aim of this research is to understand the ecological relationship between sand vegetation and environment, adaption charactristics of psammophilous plants to sandy environment and feature of plant resources in Otindag Sand Land, and further to provide theory evidence for selection optimal sand-fixation species and planning feasible process of vegetation restoration in desertification control.

本论文的目的是了解沙地植被与环境的生态关系、沙生植物适应沙地环境的特点以及沙地植物资源特征，为在沙漠化防治中选择合适的治沙物种、制定合理的植被恢复方案提供理论依据。

Based on a series of field investigation into psammophytic vegetation in Horqin sandy land and laboratory analysis of soil properties, the relationship between biodiversity and soil fertility characteristics were analyzed.

Desertification is a kind of land deserting. It's mainly caused by climate and reasonless human activity.

论文摘要沙漠化是土地荒漠化的一种类型，主要成因是气候因素和人类不合理的生产活动。

Minqin Basin has been undergoing a rapid decline of underground water level and a quickening process of desertification, salinification and vegetation degeneration that have greatly affected human behavior in water use, especially in agricultural production and farmers' health.

该地区地下水位迅速下降，沙漠化、土壤盐渍化、植被衰退过程加快，这些生态环境变化对人类的生产、生活造成了重大而深刻的影响，并对人类身体健康造成了持久的危害。

A study which published in the magnize of science of 9th January showed: the damage which releated to climate is uncompensable (more serious and frequent storms, increasing of sands, rising of sea level ). High temperature will decrease the ability of world provide to itself.

在一月九号出版的自然科学杂志上发布的一项研究显示：与气候相关的其它损害是无法补偿的（更严重更频繁的风暴，沙漠化增加，海平面上升），高温将严重减少世界供养自己的能力。

The unsafely land right is the warm bed for land resources over exploration;forest and grassland right empty and imperfect have lead over uses of these resources and also restrict investment enthusiasm;investment main body fault location, unstable policies, restrict among departments, poor expiation mechanism and un-rational water resources management policy, these all have cause un-effect desertification control.

土地权属的不安全给人们随意开垦土地提供了负向激励；林权草权虚置和缺位，导致人们竞相利用，制约投资者积极性；投资主体错位，政策的不可持续性、部门间的相互制肘、补偿机制无力、水资源管理制度不合理等导致不能有效防治土地沙漠化。

China has passed its experiences and techniques on controlling desertification and building ecological agriculture on to many countries through the UNEP.

在环境署的组织下，中国将防治沙漠化、建设生态农业的经验和技术传授到许多国家。

After Kara Thrace crash-lands on a deserted moon, why does Roslin argue with William Adama about the search-and-rescue mission?

在卡拉·瑟瑞斯迫降在沙漠化卫星之后，罗斯林为什么在搜救行动上与阿达玛争论？

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。
