Abstract: The factors which lead low-benefit protection of Pinus yunnanensis stands were studied after investigation of 88 sample plots distributed in the PianXi Region of pinus yunnanensis in Sichuan Province. By stantistic analysis, identification types and stand structure of low-benefit protective pinus yunnanensis stands were classified. The measures of management and reformation of low-benefit protection stand were suggested in accordance with the characteristics of stands, the properties of forest soil and the condition of enviroment in upper reaches of the Changjiang River.

Key words: PINES, PINUS YUNNANENSIS, LOW-BENEFIT FOREST, STAND STRUCTURE, IDENTIFICATION TYPES, STAND CONVERSION
