基于同一地区水面蒸发站点优化分析方法研究——以江西省宜春市袁州区为例

Optimal Analysis of Water Surface Evaporation Station Network in the Same District—Taking Yuanzhou District, Yichun City, Jiangxi Province for Example

土库水文站和四方井水文站同属江西省宜春市袁州区,本文将土库水文站人工观测蒸发与四方井水文站自动监测蒸发进行比对观测,进行一致性和误差分布情况分析,并采用统计学方法F检验、t检验对布设于同一行政区的两观测场蒸发观测数据进行统计分析,从误差分布和统计学方法探讨土库水文站蒸发观测项目撤销的可行性,为赣西地区蒸发站网优化提供技术支撑。

Tuku and Sifangjing hydrologic stations are both located in Yuanzhou District, Yichun City, Jiangxi Province. In this paper, the agreement rate, absolute error distribution, F-test and t-test analysis of water surface evaporation data collected by manual observation at Tuku hydrologic station and collected by automatic observation at Sifangjing hydrologic station were analyzed. The feasibility of evaporation observation pro-ject revocation of Tuku hydrologic station was discussed by error distribution analysis and statistical methods, which could offer technical support for monitoring station network optimization in West Jiangxi area.
