摘要

以秦淮河流域为研究区域,利用现代遥感、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,细致地刻画了流域内的水文过程,建立了研究区域数字水文模型。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

Due to the land use changes the natural hydrological circle process and the quality and quantity of water resources are changed greatly, which will influence the development of socio-economy and the quality of the ecological system to a certainty. A research on effect of land use changes on hydrological system, especially on water balance and flood protection is not only of significant academically, but also applicable with regard to different fields relating to sustainable development of the society and sustainable use of resources and environment conservation. The paper mainly study on development of the regional digital hydrological model and predictions of impact of land use changes on the hydrological system by means of a case study of Qinhuai river catchment within Jiangning county. The digital hydrological model is developed, which can describe spatial-temporal changes of the hydrological circle and conveniently output the spatial distribution of hydrological variable and state. It can simulate the impact of the land surface characteristics on the hydrological process too. Its partial parameters can be determined by the geographic information and land surface characteristics and the model calibrating is less dependent on the historic data. So the model can be applied in region lack of hydrological data and can simulate land use changes scenarios with specified representative parameters. Several land use changes scenarios of study area are defined and the scenarios are simulated by the digital model. The results show that the model can reflect the impact of different land use changes on the hydrological system, especially on water balance and flood protection within the catchment quantitatively and qualitatively.
