水文学原理 meaning in Chinese

hydrology

For this reason , our objective is the research of the mechanism of runoff generation and characteristics of moisture changing process of slope farming purple soil , accordding to the theory of hydrology and the intergrated - means of compined the hydrology with the peodology , because it is the basis of the studies : soil erosion and protection , farming - land water balance , non - point pollute , etc . , and the direction gist of runoff arrange implement , solving water hazard and management of irrigation and fertilizer
综观国内外有关研究，我们认识到对紫色土土壤产流和水分变化特征的认识，是认识该区土壤侵蚀与保护、农田水量平衡、非点源污染等的机理和规律的基础，也是解决该区水患问题、实施径流调节而提高旱地的雨水利用程度，以及水肥管理等的基本科学依据。因此，以水文学原理为基础，采取水文学与土壤学、地理学、水土保持学等相结合的途径，研究紫色土坡耕地的降雨产流机制与产流后土壤水分的变化特征，是具有新的科学价值和现实意义的。
