Study On The Yellow River Water Optimized Allocation Scheme For Shandong Province

Water was redistributed based on the water-saving level of the agriculture and industry.Based on the irrigation water use coefficient index of agriculture and water consumption per10thousand Yuan of value-added by industry, an advanced water-saving index system wasestablished. Comparing the actual water level with advanced water-saving index, the wateramount was redistributed. Specifically, water subtraction was less with high water-savinglevel and water subtract was more with the low water-saving level. The conclusions areshowed as follows:The water distribution index was linked to the water-saving level, and the mathematicalmodels of three typical years on the Yellow River in Shandong were set up with thesimulation by GAMS software respectively. In three cases of the water amount reduced by10%,20%and30%, the water amounts of the Yellow River in Shandong in three typical yearswere calculated. A new optimized allocation scheme was proposed, which solved the problemthat the agricultural and industrial water in various cities are reduced with the same proportion.Generally, it is of great practical significance for water dispatching management.With the analysis of the typical years’ optimized scheme, it was shown that theagricultural water subtractions of Zibo, Qingdao, Jinan, Weifang, Jining and Binzhou wereless with high water-saving level of the agriculture and the agricultural water subtractions ofDezhou, Dongying and Heze were more with low water-saving level of the agriculture. Thesubtracted water was transferred to the high water-saving level area from the low area. Inthree cases of the water amount reduced by10%,20%and30%, the subtracted watertransferred to the high water-saving level area in the very dry year was separately10.90,21.79and32.69million m3. Agricultural production value increased76.56,153.07and229.61million Yuan respectively. And the grain output increased20.33,40.64and60.96thousand tonrespectively. The subtracted water transferred to the high water-saving level area in the dryyear was separately17.23,34.47and51.70million m3. Agricultural production valueseparately increased119.35,238.76and358.11million Yuan. And the grain output separatelyadded27.68,55.33and82.99thousand ton. The subtracted water transferred to the highwater-saving level area in the normal year was separately11.26,22.52and33.78million m3. Agricultural production value added141.61,283.18and424.82million m3separately. Andthe grain output added27.27,54.54and81.82thousand ton separately.The industrial water subtractions of Qingdao and Dongying were less with highwater-saving level of the industry and the industrial water subtractions of Heze, Liaochengand Jining were more with low water-saving level of the industry. The subtracted water wastransferred to the high water-saving level area from the low area. In three cases of the wateramount reduced by10%,20%and30%, the subtracted water transferred to the highwater-saving level area in the very dry year was separately19.97,39.94and59.91million m3.The industrial GDP added6.33,12.65and18.99billion Yuan separately. The subtracted watertransferred to the high water-saving level area in the dry year was separately19.65,39.29and58.94million m3. The industrial GDP separately added8.37,16.74and25.11billion Yuan.The subtracted water transferred to the high water-saving level area in the normal year wasseparately14.70,29.40and44.11million m3. The industrial GDP added23.91,47.82and71.73billion Yuan separately.Under the circumstances of the water amount reduction, the transferred watersignificantly increased the social and the enterprise economic benefit, and it will play animportant role in the construction of water-saving society.
