水文学

Soil moisture is an important factor in research fields of hydrology,meteorology,pedology,ecology,agricultural science and so on.

土壤水分是水文学、气象学、土壤学、生态学以及农业科学等研究领域中的一个重要的参数，也是一个比较难得到的参数。

Soil moisture is an important factor in research fields of hydrology, meteorology, pedology, ecology, agricultural science and so on. But it is a difficult one to gain.

土壤水分是水文学、气象学、土壤学、生态学以及农业科学等研究领域中的一个重要的参数。

The study of soil degradation has become the focus of the 21st century inter- national pedology, agronomy, hydrology, environmental science and soil erosion science, however, a lot of theoretical problems and course mechanism aboutsoil degradation are uncertain hitherto.

土壤退化研究已成为21世纪国际土壤学、农学、水文学、环境科学及侵蚀学科关注的热点，但是直到今天为止有关土壤退化的许多理论问题及过程机理尚不清楚。

Slack water deposits are indicators of water level and age of paleoflood. They can be identified using Quaternary Period geology and hydrology, and can be aged using radioactive isotopes or other methods.

平流沉积物是洪水水位和发生年代记录的载体，利用第四纪地质学和水文学可以把它发掘出来并用放射性同位素或者其它断代方法测定它发生的年代，再通过断面恢复，进行流量推求，这就是古洪水研究。

This study is of significance to the decision of parameters of sprinkle technology and the study of hydrological stream.

研究结果对喷灌灌水技术参数的确定及水文学的径流研究有重要意义。

Hydraulic adjustment and pollution control measures, combining the knowledge of hydrology, biochemistry and algous ecology, are the main practices of integrated controls.

该技术以水利调节与污染控制为主要手段，利用水文学、生物化学、藻类生态学对河流&水华&进行综合控制。

Under coaction of endogenic geological processes and water and heat conditions, the drainage development, and water formation and transformation in the inland watershed. were indicated hydrological characteristics of periglacial zone. The hydrological process is mainly related with to changes in mountain areas. It by 41% of precipitation in mountain areas as surface discharge flows into middle and lower reaches, which makes up a main physical basis of the quantitative and qualitative relationship for various functional units in the eco-system in mountain front plain.

在内动力地质、水热条件的共同作用下，内陆河流域上游山区的水系发育、水的形成和转化反映出冰缘带水文学特征，水文过程主要和气候变化相关联，山区降水总量的41％以地表径流形式输入中下游地区，构成山前平原生态系统各功能单元数量与质量关系的主要物质基础。

This paper proposed robust characteristic function for real-time flood forecasting system,and established the dynamitic monitor module for rainfall error,and researched dynamitic robust estimation for AR model parameters.

把抗差估计理论引入实时洪水预报系统，提出适合于实时洪水预报系统的抗差特征函数，建立降雨误差的动态监控模式，研究实时修正模型参数的动态抗差估计，结合洪水预报模型，形成具有水文学特点、抗差性强的实时洪水抗差预报系统。

The state-of-art of the study of grey theory in estuarine science is expatiated in detail.

此外说&河口学&是&河口水文学&的简称不妥。
