王河地下水库是滨海平原有坝型地下水库,具有防治海水入侵和供水的双重功效. 为正确认识王河地下水库所提供的相关经济及生态效益,合理评估其效益价值就显得尤为必要. 采用相关价值评估方法,分别评价了王河地下水库的征地节约、蒸发节约、水源涵养和调蓄洪水、防治海水入侵、提升地下水位、恢复湿地、供水以及粮食增产等效益价值. 经过计算,各项效益价值量从大到小依次为征地节约>防治海水入侵>涵养水源、调蓄洪水>粮食增产>供水>蒸发节约>恢复湿地>提升地下水位,效益估值分别为1 .84亿元、6619 .59万元、4648 .97万元、2647 .23万元、1269 .29万元、903 .62万元、819 .9万元和646 .36万元. 相比较淡水供给这一直接效益价值,王河地下水库提供了更为丰富也更为庞大的间接效益价值,为地下水库效益评估提供了有益的参考.
王河地下水庫是濱海平原有壩型地下水庫,具有防治海水入侵和供水的雙重功效. 為正確認識王河地下水庫所提供的相關經濟及生態效益,閤理評估其效益價值就顯得尤為必要. 採用相關價值評估方法,分彆評價瞭王河地下水庫的徵地節約、蒸髮節約、水源涵養和調蓄洪水、防治海水入侵、提升地下水位、恢複濕地、供水以及糧食增產等效益價值. 經過計算,各項效益價值量從大到小依次為徵地節約>防治海水入侵>涵養水源、調蓄洪水>糧食增產>供水>蒸髮節約>恢複濕地>提升地下水位,效益估值分彆為1 .84億元、6619 .59萬元、4648 .97萬元、2647 .23萬元、1269 .29萬元、903 .62萬元、819 .9萬元和646 .36萬元. 相比較淡水供給這一直接效益價值,王河地下水庫提供瞭更為豐富也更為龐大的間接效益價值,為地下水庫效益評估提供瞭有益的參攷.

Wanghe groundwater reservoir is a kind of coastal plain groundwater reservoir with under -ground dam and has double benefits of preventing seawater intrusion and providing fresh water .In order to correctly understand economic and ecological benefit ,it is necessary to reasonably assessthe benefit val-ue of Wanghe groundwater reservoir .The paper used related evaluation methods to analyze the benefit val-ues such as saving of land requisition and evaporation , water conservation , adjustment and storage of flood,prevention of seawater intrusion , enhancement of groundwater level ,restoration of wet land , water supply and increase of grain yield .The result shows that the values of benefit from big to small in turn land are saving of land requisition >prevention of seawater intrusion >water conservation ,adjustment and storage of flood>increase of grain yield>water supply>saving evaporation>restoration of wet land>en-hancement of groundwater level , whose valuesare about 184, 66.2, 46.5, 26.47, 12.69, 9.04, 8.2 and 6.46 million yuan separately .Comparing direct benefit stemming from water supply , the Wanghe groundwater reservoir provided the greater and richer value of indirect benefit .This result can provide ref-erence for benefit evaluation of similar groundwater reservoir .
