摘要
用遥感资料建立的分块产流模型，充分考虑了降雨的空间分布不均匀性，解决了以往分块产流计算中产流参数难以分块选择的缺陷，提高了产流计算的精度。利用遥感资料提取产流参数，可以从参数与流域自然地理特征关系进行分析，使之更符合水文现象的一般规律，并可用于无资料地区。
This model, which is built using remote sensing data, has been fully considered the bad distribution of precipitation in area, and has solved the problem that yield runoff parameters can't separate selection in other scatter model. It improves the calculation precision of runoff yield. Using remote sensing data can extract yield runoff parameters effected by natural geographical factors, and the parameters will conform to the general regulaity of hydrology. It can be used in the areas without data available.
