Evaluation of Region Water Resources Carrying Capacity Based on Set Pair Analysis Technology

To solve the descent of groundwater level in Sanjiang Plain, taking Hongxinglong branch of Heilongjiang Land Reclamation bureau as an example, the water resources carrying capacity of 12 farms in the area were evaluated by set pair analysis technology. The results indicated that the water resources carrying capacity of 291 and Jiangchuan farms were in grade III, Raohe farm between grade II and III, 853 and Baoshan farms in grade II, Youyi and 597 farms between grade I and II, and 852, Shuangyashan, Shuguang, Beixing and Hongqiling farms in grade I. The results reflected the exploitation and utilization degree of region groundwater resources, and provided basis for the restoration and scientific management of groundwater resources in Hongxinglong branch and even Sanjiang Plain.
