水土

Three seriousenvironment problems of the soil erosion, desertification and salinization in the aridand semiarid area not only endanger the throughput and the stability of the dry landfarming, but also jeopard the country ecosystem security.

干旱、半干旱地区的水土流失、土地沙漠化、土壤盐碱化三大环境问题，不仅直接危害北方旱地农业系统的生产能力和稳定性，而且危及到了国家生态安全建设。

It was considered that the evergreen and deciduous broadleaved mixed forest including Cyclobalanopsis glauca,Lithocarpus glaber,Castanopsis sclerophylla,Phoebe hunanensis,Cinnamoum chckiangcnsis and C.comphora etc.can be rebuilt in the local area of Zhongshan mountain.

作者认为，如果不再受人为破坏，在紫金山水土条件好的山腰和山麓的地段，可以建立包含青冈、苦槠、石栎、浙江桂和樟树等常绿阔叶树种的常绿落叶阔叶混交林。

But,this capital construction has created a great quantity of secondary slopes and resulted in series environment problems.It divides slopes into three categories of lithoid slope,terrene slope and water body slope according to the characteristics of slope management and referring to the standards of slope category both at home and abroad.

这些基础设施建设破坏了原有植被及原生植物群落，造成了大量次生边坡，导致了一系列的环境问题，如水土流失、滑坡、泥石流、气候变化、生物链破坏等，引起了社会各界的重视，先后兴起了许多的防护措施，如传统的硬性支护，有挡土墙护坡、浆砌石等封闭护坡技术措施。

This is a stretch of the lithoid mountain exposing from the loess formation as thick as a hundred meters, where the ancient story of the strata evolution and vicissitudes has been recorded; the layers of annual rings have witnessed the tremendous damages brought by the soil erosion to the Loess Plateau.

这是一段厚达百米的黄土层中所暴露出的石质山体，这里记载着地层演变的古老故事和历经的风雨沧桑，一层层的年轮上留下的就是水土流失带给黄土高原巨大侵害的历史。

The institute takes loessial plateau as key research,take on research on water and soil conservation in semiarid and simewet area,and solve some important technology problems in entiron building.

中国科学院、水利部水土保持研究所成立于1956年2月，是中国科学院在西北地区建立的第一个研究机构。

Melinis minutiflora was suitable for water and soil conservation. A field study on its photosynthetic characteristics was carried out by using LI-6400 portable photosynthesis system in May.

糖蜜草为禾本科软草，足复垦和水土保持的良好植物。5月份选取晴天用LI-6400便携式光合仪测定糖蜜草的光合特性。

The effects of lithology to sensitivity of water and soil loss are stronger in carbonate rock areas than noncarbonate rock areas.

作为生态功能区划的基础性工作，针对桂西北喀斯特地区生态环境特征，以河池市为例，分别建立了碳酸盐岩区域和非碳酸盐岩区域水土流失敏感性评价指标体系。

The organic designation is a legal term on labels for certain nonchemical winemaking and farming practices, whereas the Code of Sustainability is a broader concept of continually improving farming and winemaking practices, enhanced relations with staff, neighbors and communities, preservation of the land and conservation of natural resources.

标签上的有机物名称是一个法律条款，是指对于某个不使用化学成分的葡萄酿造和种植实践。然而这个可持续葡萄种植和葡萄酒酿造代码却有着更广泛的意义，它包括不断提高农业和葡萄酒酿酒业的实践水平，提高工作人员、邻居和社会团体之间的联系，保护水土和自然资源。

Using the thickly galvanized stonemesh filled with the Lijiang overbank pebbles for bank revetment solved the problems that traditional grouting rubbles for bank revetment influences the Lijiang natural landscape, the ordinary stonemesh is corroded and destroyed easily and the hard plastics stonemesh stiffness can t meet demand.

采用重镀锌铁丝网笼填入漓江漫滩上的卵石进行护岸，解决了传统的浆砌石护岸影响漓江自然景观和普通铁丝网笼容易被锈蚀破坏及硬塑料网笼刚度不够的问题，使护岸工程恢复了漓江原有的自然景观，达到了防治水土流失和美化漓江的目的。

Control of soil and water loss on the Loess plateau emphasizes on oversand and coarse sandy area, Silt-arrester dam is the key to the object.

黄土高原水土流失治理的重点在多沙粗沙区，淤地坝是实现治理目标的关键措施。

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。
