| description | To explore the calculation method of effective utilization coefficient of farmland irrigation water in the mountainous area of Yunnan Plateau,we scientifically evaluated the efficiency of farmland irrigation water.Taking Yongshan County of Zhaotong City,Yunnan Province as the research area,we selected 2 sample irrigation districts and15 typical fields to calculated and analyze the effective utilization coefficient of farmland irrigation water.The net irrigation water of sample irrigation districts was calculated after measurement and investigation.Head-end measurement was used to calculate and analyze the effective utilization coefficient of farmland irrigation water in the sample irrigation districts,and then the coefficient of Yongshan County from 2018 to 2020 was calculated.The results show the followings.① The net irrigation water in the sample irrigation districts of Yongshan County exhibited a downward trend from 2018 to 2020 overall.The net irrigation water for Zanthoxylum bungeanum,Amomum villosum,Citrus reticulata,flue-cured tobacco and Solanum tuberosum in Yongshan County decreased successively.② The effective utilization coefficient of farmland irrigation water was larger in the medium-sized irrigation district than in the small irrigation district.③ The effective utilization coefficient of farmland irrigation water in Yongshan County was increased gradually from 2018 to 2020,i.e.,0.489 2,0.502 0 and 0.508 5,respectively.The research results are reasonable and reliable,which can reflect the actual situation in the irrigation districts. |
