- [目的]流域产水系数的变化反映了降雨和下垫面变化的综合影响,研究产水系数的变化特征对流域水资源合理调控具有重要意义。[方法]以延河流域为研究区,采用一元线性回归和Mann-Kendall方法分析生长季产水系数的变化趋势,结合NDVI、降雨量、暴雨日数和无雨日数4种产水系数影响因素进行空间聚类分析,并探究其时空变化特征。[结果]2001—2017年延河流域生长季的产水系数呈现波动增加趋势,但增加趋势不显著,且大部分区域变化幅度相对较小,倾向率介于-0.017～0.031/10 a,延河流域生长季平均产水系数空间上呈北向南、西向东逐渐增大,大部分区域存在不显著的上升趋势,西北部区域产水系数呈不显著的下降趋势,中部部分区域呈现显著的上升趋势。[结论]就变化率而言,产水系数与降雨量、暴雨日数呈正相关,与无雨日数和NDVI呈负相关。就多年平均值而言,平均产水系数与平均降雨量、暴雨日数和NDVI均呈现正相关关系,与无雨日数呈负相关关系。延河流域产水系数时空变化特征及影响因素分析可为干旱半干旱区流域水资源管理和规划提供理论支撑。
- Abstract:
- [Objective]The change of water yield coefficient in the basin reflects the comprehensive influence of rainfall and underlying surface change. It is of great significance to study the change characteristics of water yield coefficient for reasonable regulation of water resources in the basin. [Methods] Yanhe River Basin was taken as the study area, the change trend of water production coefficient in the growth season was analyzed by using the unitary linear regression and Mann Kendall method. The spatial clustering analysis was carried out in combination with the four factors affecting the water production coefficient, namely NDVI, rainfall, rainstorm days and rainless days, and the spatiotemporal change characteristics were explored. [Results] From 2001 to 2017, the water yield coefficient in the growth season of the Yanhe River Basin showed a fluctuating increasing trend, but the increasing trend was not significant, and the change range in most regions was relatively small, with a tendency rate between 10.017/decade and 0.031/decade. The average water yield coefficient in the growth season of the Yanhe River Basin increased gradually from north to south and from west to east in space, and there was an insignificant upward trend in most regions. The water yield coefficient in the northwest region showed an insignificant downward trend, the water yield coefficient in the central part of the region showed a significant upward trend. [Conclusion] As far as the change rate is concerned, the water yield coefficient is positively correlated with rainfall and rainstorm days, and negatively correlated with rainless days and NDVI. As far as the multi-year average value is concerned, the average water yield coefficient has a positive correlation with the average rainfall, rainstorm days and NDVI, and a negative correlation with the number of rainless days. The analysis of temporal and spatial variation characteristics and influencing factors of water yield coefficient in Yanhe River Basin can provide theoretical support for water resources management and planning in arid and semi-arid regions.
