基于多源遥感协同的灌溉用水动态监测方法研究
Research on dynamic monitoring method of irrigation water based on multi-source remote sensing collaboration
摘要
Abstract
Comprehensive coverage of agricultural water metering is difficult and costly,and rapid and accurate monitoring of agricultural irrigation water use has become a prominent problem in water resources management.Compared with traditional ground station monitoring and manual statistical reporting methods,remote sensing ena-bles quick observation and coverage of a large area,providing high-frequency spatiotemporal change information in the region.This paper employs a collaborative method using multi-source remote sensing to improve the temporal continuity of high-spatial resolution data and incorporates the error characteristics of multi-source data to establish a collaborative scheme for soil moisture inversion in multi-source remote sensing.Based on the change of soil sur-face moisture,the actual high-frequency and high-precision actual irrigation area in the study area was identified.Combined with crop surveys and per-mu water consumption measurement results,the irrigation water volume of different irrigation cycles in the study area was estimated,with an average accuracy of 87.57％,which improved the high cost and high manpower demand of traditional irrigation water monitoring.By using the results of irrigation water volume estimation as the basis for water rights supervision,the study completed the dynamic update of water rights balances of different farmers in the study area,providing a new way for water resources management and wa-ter rights promotion.关键词
