| Abstract: |
| 【Objective】The purpose of this paper is to analyze the spatial distribution characteristics of water resources in the agricultural system of the Yellow River Basin,【Method】Taken the Yellow River Basin as the research object, emergy theory and method, spatial autocorrelation analysis and spatial lag regression model were used to investigate the spatial distribution characteristics of water resources value of Agricultural System and its main influencing factors in the Yellow River Basin. 【Result】①The value of water resources in agricultural system ranged from 4 to 6 yuan/m3, and the value of water resources in the middle of the basin was higher;②The global Moran index of water resources value in agricultural system was 0.277 2, showing a positive spatial autocorrelation. The high-value agglomeration (H-H) was mainly concentrated in the middle of the basin; ③The main influencing factors of the spatial change of water resources value in agricultural system were GDP, altitude and water consumption. 【Conclusion】The value of water resources could guide its distribution. Increasing the agricultural water consumption in the middle and lower reaches was conducive to improving the agricultural production efficiency of water resources in the whole basin. |
