This article differentiates and analyzes the relevant concepts about the ecological enviromnent, and puts forward the defined concept of the rights to the ecological environment water utilization. In addition, it points out the characteristic of those rights, and does elementary study on the allocation principle, methods, and steps on the rights.展开更多
