The Problems in and Optimizing Countermeasures on Supply and Demand of Water Resources in Northeast China

Based on water resources data of northeast China and its dynamic change,the paper comprehensively analyzes the situations of water resources supply,demand and utilization. The research results show that the total and average per person of water resources are low,and their distributions are uneven; the development and utilization of water resources is higher,and that of Liaoning province is the highest,i.e. 45.67%; the water shortage is serious. The accounts of water for agriculture is more than 60%,and water for environment is serious insufficient; the insurance system of water resources supply has not formed,and the capacity of distribution and control of water resources is limited in northeast China. Finally,in response to the existing problems in the use of water resource,the paper provides some countermeasures on optimizing supply of water resource in northeast China:first,it should control underground water usage and strengthen water pollution treatment; second,it shoud improve water resouces utility to save water; Third,it should improve wator resaurces usage level.
