为了研究分布式水文模型与GIS耦合以及干旱区产汇流过程模拟,采用GDAL(Geospatial Data Abstraction Library,地理空间数据抽象库)对GeoTIFF文件进行操作,结合栅格叠合的空间分析方法及分布式融雪洪水模型,并应用面向对象的思想建立了分布式产汇流过程模拟系统。最后通过在新疆军塘湖流域的模拟应用,结果表明该系统模拟的可靠性和准确性,可以为研究区的水资源综合利用和管理提供重要参考依据。
英文摘要:
In order to study the coupling of the distributed hydrological model and GIS and simulation of the arid area runoff and the confluence process, using GDAL(Geospatial Data Abstraction Library) to operate GeoTIFF files, combined with a grid superimposed spatial analysis methods and distributed snowmelt flood model, and adopting the idea of object-oriented, the paper built the distributed runoff process simulation system. Through simulation application at Juntanghu basin in Xinjiang, the results show that the simulation system is reliable and accurate and can provide an important reference for future comprehensive utilization and management of water resources in the study area.
