摘要
定性、定量分析了我国有效灌溉面积的影响因素,并采用灰色关联分析法确定各指标对有效灌溉面积的影响。结果表明,以灰色综合关联度作为标准,5个主要影响因素依次为灌溉工程及设备、灾害影响、耕地面积、资金投入、灌溉用水量,其灰色综合关联度分别为0.577、0.546、0.538、0.534、0.525。
The influencing factors of effective irrigation area were analyzed qualitatively and quantitatively, and the gray related analysis method was used to figure out the impact of each index lays on effective irrigation area. The results indicated that with gray comprehensive related grade as the criterion, the gray comprehensive related grade of irrigation engineering and facility was the top, followed by catastrophe influence, cultivated area, investment, and irrigation water, whose gray comprehensive related grades were 0. 577,0. 546, 0. 538, 0. 534, 0. 525, respectively.
