水土

Since the 1980s China has made great efforts to conduct the construction of ecological agriculture and has tried every means to find a sustainable agricultural development mode that can not only increase the output of grain and other farm produce, but also help improve the ecological environment.

八十年代以来，中国积极进行生态农业建设，寻求既能增产粮食等农产品，又能使生态环境得到改善的农业可持续发展模式：综合治理小流域水土流失面积6700多万公顷；建立了不同类型、县乡村不同规模的生态农业试点2000多个

The summer camp I am very happy, there are a lot of harvest, I work on the importance of soil and water conservation with the further understanding.

这次夏令营活动让我感到很快乐，也有很大的收获，我对水土保持工作的重要意义有了更进一步的理解。

Critical natural processes are analyzed systematically at the national scale, including headwater conservation, soil erosion prevention, storm water management and flood control, desertification combating and biodiversity conservation.

国土尺 度生态安全格局通过对江河源区水源涵养、洪水调蓄、沙漠化防治、水土保持和生物多样性保护5个维护生态安全最关键的自然过程进行系统分析评价而划定。

The selection of the plants in the water and soil conservation should adhere to the principle of panting suitable trees in suitable places,emphases the diversity of the tree species,make the arbors and bushes be mixed and matted with the herbages for meeting the natural growing regularities and forming a long-term and stable ecological community.

水土保持中植物的选择，要根据适地适树的原则，强调树种多样化，使乔木和灌木混交并与草本植物搭配，符合自然生长规律，形成长期稳定的生态群落。

Stability of 14 high-cut slopes in Guangdong province is analyzed with typical rock mass structure analysis method and stereographic projection method, and with the numerical simulation method UDEC this paper simulated the excavation and reinforcement courses of the important slopes. Some conclutions and suggestions are based the analysis above.

本文结合广东某省道沿线14个高陡岩石边坡的开挖和支护方案的选择设计，运用常用的岩体结构分析方法和赤平投影方法对边坡的稳定性进行了分析，采用UDEC数值模拟方法对一些重点边坡的开挖支护进行了模拟，得出了以下一些结论： 1、边坡支护形式的选择应遵循&安全绿色、水土保持、恢复自然、环保之路&的设计原则。

I use shrub-style sprinklers mostly on inaccessible hillsides where we are trying to grow plants for erosion control.

我是用灌木式喷头主要是为了灌溉难以接近的山地，这里种的是防止水土流失的植物。

Not only does the moisture loss stunt summer growth but the warmer winter temperatures actually lead to more ice on the ground, keeping livestock from reaching the plants that survived.

不仅水土流失阻碍了夏季植物生长，暖冬也导致地表上留有更多的冰，使牲畜无法触及存活的植物。

The development of the subject of Agricultural Soil and Water Engineering of Hohai University was based on the old subject of Irrigation and Drainage Engineering.

河海大学农业水土工程学科是在原农田水利工程学科的基础上发展起来的。

The principle new development of modern irrigation engineering.

灌溉原理与技术》是农业水土工程学科中一门理论与技术兼备的专业课程，主要讲授现代科学灌溉理论的生理学和物理学基础，作物需水量计算理论与方法，非充分灌溉的科学依据与研究进展，现代灌溉方法的原理与研究进展，旨在使学生掌握现代灌溉学科的基本理论，了解本学科的关键技术、发展趋势与存在的问题，掌握相应的工程技术，培养学生建立现代灌溉的新观念和新理念，在理论和实践上奠定学生深入研究灌溉学科中的有关理论和技术的创新能力基础。

Visitors who aren't interested in the supposedly life-prolonging Air or soil will still find much to admire in the region's scenic limestone karsts, mud and stone Dwelling s and breathtaking caverns that are a natural sculpture gallery.

即便对当地延年益寿的水土不感兴趣的游客仍然能够在这里找到足以让他们留连忘返的景致──优美的石灰岩地形、独特的泥石建筑、令人叹为观止的天然岩洞，简直堪称一个自然雕塑博物馆。

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。
