Abstract:

The aquatic vascular plants in our country is rich in flora, wildly distributed and with a higher productivity. So far as the productivity, the richest rcsouccs arc concentrated in the East and North-East areas but more rich floristic resources arc found in the plateau, mountainous areas and hilly lands of our coun-try. Considering the aspects of economic, social and scientific effect, we classify the aquatic plant resouccs maily into three groups. Based on the understanding of biotic levels, six utilizable homologous levels were recognized. Some of the chara-cters and questions on the current utilization of the resources were discussed and analysed. Furthcrly, some exploitation countermeasures and projects necessarily to be studied on the resources of aquatic plant were proposed.

Key words: Aquatic plant, Resource, Exploitation
