Analysis on the Key Factor of Irrigation Water Use Efficiency in Different Districts
摘要
Abstract
Based on the dynamic change of irrigation water use efficiency in different districts in China,the key factors of irrigation water use efficiency in different areas were analyzed using SPSS19.0 software during the period of “Eleventh Five year Plan”.The results showed that GDP was the key factor of irrigation water use efficiency in 6 subregions.What's more,water-saving irrigation areas,especially low pressture pipeline irrigation area,had an obvious impact on irrigation water use efficiency of pure well irrigation district in North China; irrigation area significantly affected irrigation water use efficiency of small-scale irrigation district in northeast of China; water consumption of gravity irrigation had an obvious impact on irrigation water use efficiency of large-scale irrigation district in southeast of China; in central district of China,irrigation area affected irrigation water use efficiency of pure well irrigation district and small-scale irrigation district obviously; Irrigation water use effiviency was affected by area of water-saving irrigation project in southwest of China; total irrigation area influenced irrigation water use efficiency of pure well irrigation district significantly in northwest of China.关键词
