Natural Geographical District of Honeybee in China;

Three dimensional localization algorithm based on nectar source localization model in wireless sensor network;

The familiar nectar plants in partial region of Yunnan were surveyed.

The represention of the research of the paper is mainly on nectar plants of 10 fandlies,12 genera, 17 species and 3 variety species.

After the preliminary appraisal,38 species of pollinators were caught on 22 kinds of nectar source plants,diptera and hymenoptera were the main pollinators.

Variety,characteristics,present exploitation situation,existing problems,exploitation prospect and methods of the wild nectar source plant recources in Changbai Mountains were produced,which provides some source materials for the exploitation of this valuable resources in or out our country.
