三江平原井灌区地下水资源承载力物元评价模型

揭示三江平原地下水资源安全状况,以红兴隆分局为例,采用物元分析法对其下属12个农场的地下水资源承载力进行综合评价。结果显示:五九七、饶河、二九一和江川农场的地下水资源承载力等级为Ⅲ级,已接近饱和值应以控制地下水开采、合理利用地表水资源为主;宝山农场的地下水资源承载力等级为Ⅱ级,当地地下水资源开发利用已有相当规模,但仍有一定的开发潜力;友谊、八五二、八五三、双鸭山、曙光、北兴和红旗岭农场的地下水资源承载力等级为Ⅰ级,这7个农场的地下水资源承载能力较大,状况较为乐观。物元分析方法为水资源承载力评价提供了一种更为简便的方法,同时为政府科学管理三江平原地下水资源提供了决策依据。

Matter-element model on groundwater resources carrying capacity evaluation in well-irrigation area in sanjiang plain

In order to reveal safety situation of regional groundwater resources,through taking Hongxinglong branch bureau for example and using the Matter-element model,the groundwater resources carrying capacities of twelve farms belong to Hongxinglong branch bureau were evaluated comprehensively.The results show that the groundwater resources carrying capacities of Farm 597,Raohe River,291,Jiangchuan are in Ⅲ degree which the carrying capacity have been close to saturation and should control groundwater exploitation and make mainly rational use of surface water;the groundwater resources carrying capacities of Baoshan are inⅡgrade,their groundwater resources exploitation and utilization have had considerable scale,but still have some potential;Farm Youyi,852,853,Shuangyashan,Shuguang,Beixing and Hongqiling are inⅠgrade,their groundwater resources still have higher carrying capacities and the state is more optimistic.The matter-element analysis method provides a more simple method for the evaluation of water resources carrying capacity,and decision-making basis for government to scientifically manage groundwater resources in Sanjiang plain.
