浙江省实时土壤缺水量空间分布自动分析与实现

Automatic Analysis and Implementation of Spatial Distribution of Real-time Soil Moisture Deficiency in Zhejiang Province

按流域代表性和面上均匀分布要求,在浙江省区域代表站中筛选39个代表流域,利用在浙江有较好适应性的新安江三水源模型率定产流参数,借助水文遥测系统上传的实时雨量、蒸发量信息以及数据库、水文模拟、Arc GIS空间分析等技术,由代表流域土壤缺水量的实时模拟,实现浙江省土壤缺水量空间分布的逐日自动分析。

According to the requirements of representation and uniform distribution on the surface of river basin, 39 representative watersheds were selected among the stations in the whole province. The runoff yield parameter calibration of the Xinanjiang model which has a good adapt- ability in Zhejiang Province was used. Based on the real-time rainfall and evaporation information uploaded by hydrological telemetry system, database, hydrological simulation and ArcGIS spatial analysis technology, daily automatic analysis of spatial distribution of soil moisture deficien- cy in the whole province was realized by the real-time simulation of soil moisture deficiency in representative fiver basins.
