| 摘 要： | 利用遥感、地理信息系统等多种数字技术，获取流域空间分布的下垫面信息和中间状态信息，刻画了流域内的水文过程，建立了秦淮河流域基于 PCRaster软件的数字水文模型。利用所建立的数字水文模型，对定义的土地利用变化情景进行了模拟。模拟结果表明，模型可以定性和定量地反映各种土地利用变化对水资源系统尤其是对水量平衡和防洪情势的影响程度。

| Abstract: | By utilizing the technology of remote sensing and GIS the space distribution of underlying information in Qinhuai River basin is attained and the digital hydrological model based on the software PCRaster is established. The model is applied to simulate the variation of hydrological characteristics due to the changes of land utilization. The result shows that the model can both qualitatively and quantitatively simulate the impact of land utilization on water resources especially on hydrologic balance and situation of flood protection. |
