摘  要:
针对冀西北高原寒旱区农业生产的水分限制特征,研究区域降水、入渗及径流特征。结果表明,冀西北寒旱区2°~6°常见坡耕地平均径流系数达6.16%,表明区域农田在通常年景下均有产流,构成滩梁地貌之间水土空间分异的基础。坡耕地产流为降水汇集与回归补充地下水资源奠定物质基础。这一结果对指导区域降水资源化生产具有重要意义。

摘  要:
In response to the water limitation for agricultural production in the cold-arid area of the northwest plateau in Hebei Province,the characters of precipitation,infiltration and runoff were observed.The results showed that the average runoff coefficient of 2°-6°slope farmland was 6.16%.The runoff water became an important foundation for rainfall efficient utilization in this area,such as rainfall convergence,ground water recharge and soil high-efficiency.The results were useful to improve the precipitation productivity in the northwest of Hebei Province.
