Abstract: Representative models were applied to evaluating principal ecological benefits of Cupress funebis protection forest in the northern Sichuan Basin, and it showed that reasonal managements have been converted into significant benefits to harness the soil erosis and water loss of the deteriorated forests. Forests in the due sites should be complementarily managed.
