地下水可流很大范围，可以保存在地下蓄水库很长时间。

The ecological environment is good and this project will not result in the unrecoverable effects if the project is in strict control.

评价区内生态环境状况良好，如果加强管理和做好充分的恢复重建措施，工程的施工、蓄水以及运行不会对环境主体造成不可逆转的影响：3。

It was shown that forest decreased soil runoff loss and improved soil water-conserving capacity from our investigation.

森林对防治灾减灾作用非常明显，它主要是通过树冠截留、减少地表径流和提高土壤蓄水性能来实现防灾抗灾作用的。

Based on the study of several ancient cities in the Yellow River floodplain, this paper discussed the disastrous experiences of flood and waterlog and three major adaptive landscape strategies: sitting on highlands, constructing city walls and protective dikes, and reserving or digging ponds within cities.

黄河以其善淤、善决、善徙的个性，塑造了黄泛平原上独特的自然与人文景观。本文以黄泛平原的古代城镇为研究对象，探讨了黄河泛滥区城镇的洪涝灾害经验，总结了古代城市三大主要防洪治涝的适应性景观遗产：择高地而居，城墙和护城堤，以及蓄水坑塘。

Based on data collected at four stations in Daning River in the spring of 2004 and 2005, phytoplankton community structure, vertical distribution, abundance, biomass, C contents, diversity index, richness index and evenness index were studied. The causes of eutrophication and water blooms in Daning River were analysed and control measures were then put forward. The dominant species were Asterionella Formosa, Cryptomonas ovata, Cyclotella caspia, Stephanodiscus neoastraea in the spring of 2004 and those were Pandorina morum, Eudorina elegans, Cyclotella caspia, Cryptomonas ovata in the spring of 2005. Average cell densities, biomass, C contents in the spring of 2004 and 2005 were 171.1×10^5 cells/L, 12.2 mg/L, 1732.2g C/L and 113.1×10^5 cells/L, 10.1 mg/L, 1395.9g C/L, respectively.

报道了大宁河2004年春季和2005年春季浮游藻类的种类组成、垂直分布、数量、生物量以及C含量的调查结果，并应用多样性指数、丰富度指数和均匀性指数对其水质进行了综合评价；对大宁河蓄水后出现的富营养化现象和春季发生&水华&的原因进行了探讨，同时提出了控制水体富营养化的建议。2004年春季，藻类优势种为美丽星杆藻、卵形隐藻、里海小环藻和新星形冠盘藻；2005年春季的优势种为实球藻、空球藻、里海小环藻和卵形隐藻。2004年和2005年的细胞密度、生物量和C含量分别平均为171.1×10^5 cells/L，12.2 mg/L，1732.2g C/L和113.1×10^5 cells/L，10.1 mg/L，

Another conclusion is that stability is better in accretion bank than in colluvial deposit bank.A comprehensive study has been made on the course of reservoir bank recession on the theory of fluvial and wave dynamic mechanics with a view of character of mountain land. Some appraise and rectifying suggestions for current methods are given by computing the scale of the bank recession in the area.

通过对河流水动力条件、水库波动动力学等几个方面并结合山区水库特点对水库岸坡的塌岸过程进行了系统的研究，并运用不同的方法对水库蓄水后的岸坡塌岸宽度进行了预测，从预测结果对不同的方法进行了评价，并对现有的方法和结果提出了修改建议。

The canopy of the species is strong in obstructing storms and reducing soil surface erosion and the water-holding capacity.As a result,the surface erosion is less than that on the grassed slope by 11％;the litter under the canopy has a depth of 5.5 cm on the average;and each adult tree can hold 0.3～0.69 m3 of rainfall.

杨梅树冠和树形有极强的阻截暴雨，减少地表径流以及蓄水能力，地表径流比草坡减少11%，树冠下部凋落物平均厚度5.5 cm，每株成年树可保存0.30～0.69 m3的降水量。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。

Maybe they'll disappear into a pothole.
