Birch sap, as a natural resources, has been exploited. It has been resear- ched deeply in time, method and winding up of collecting sap; yield of Birch sap; influence of tree's growing by collecting Birch sap; econo- mical and social benefit of gathering sap; and composition, eatability, toxicity, health protection of Birch sap; and achieved mature rules It has been summerized systematically in this paper. Besides, the paper al- so sum up the preservation and utilization of Birch saP, which imped- ed the development of Birch sap utilization at present; list the methods that some area used to solved it; raise the thinking about the problem; and then show the problem; and then show the direction of Birch sap exploitage.
