淮北砂姜黑土区农田排水工程的水文效应

Hydrologieal Effects of Farmland Drainage Project in Black Earth with Nodular Kankar in Northern Huai Plain

本文针对生产实际,从农田排水工程的水文效应这一途径出发,通过对近20个站点的不同集水面积、不同排水工程标准的排水试验资料的分析,建立了计算特小流域的排涝模数经验公式,以及各级排水沟的规格和布置方式。

Upon analysing experimental data of about 20 observation stations with different catchment area and various project standard, an empirical formula calculating draining modulus of extremly small catchment is presented, ditch parameters and layout of the drainage system are suggested for practical use from the point of view of hydro-logical effects.
