Study on the Water Resources Assessment Indexes System

On the basis of reviewing the water resources assesgn ent research in the last two decades, the paper remarks several inportant problems to be further investigated and puts forward a proposal of building up a system of appraisal indices. This paper introduces the initial results of a group's research. A fairly sinple system，including relatively all-round naturogeographical and engineering-economical characterictics, features and their regimes, is provided to evaluate the level of utilization availability and sufficientness to meet the human dem and of water resources for a definite district. Two operating methods were applied and recommended to judge the water resources of 7 representative counties selected from different corners of China as illustrating examples.
