Aiming at the water security problem commonly concerned by authors at home and abroad presently,the authors took Land Reclamation Hongxinglong branch bureau as example,evaluated and graded the water security status of twelve farms belong to Hongxinglong branch bureau in 2006 through using the water poverty index(WPI)and sample mean value-standard deviation grade method,and the relevant countermeasures were presented according to the grade results.The results show that the WPI values of Farm 853 and Hongqiling are in safe state,the water security situations of the two farms are the most optimistic;the WPI value of Farm Raohe is in upper safe state,the water security situation of this farm is better;the WPI values of Farm Youyi,597,852,291 and Jiangchuan are in middling safe state,the water security guarantee systems of the five farms are awaited to be further strengthened;the WPI value of Farm Beixing is in lower safe state,the water security situation of this farm is worse;and the WPI values of Farm Shuangyashan,Shuguang and Baoshan are in unsafe state,the water security situations of the three farms are the worst.The research achievements can provide decision basis for reasonably exploiting and utilizing regional water resources and construction of regional water safety guarantee system.
