Abstract:

The optimum evaluation of ten types of tree species(or clones) has been accomplished, including 13 indexes of 3 categories, such as adaptability and protecting effect of tree species, social economic situation by using the analytical hierarchy process(AHP).Results showed: Among all evaluation factors, the conservation rate of tree species makes the largest contribution to optimum evaluation, indicating selecting suitable tree species is the presupposition of construction protection forest. The windbreak effect of tree species is the key of playing a synthetically protection role of farmland protection forest. Besides, only considering social economic factors can a objective and exact conclusion be obtained. The optimum evaluation of ten types of tree species(or clones) is lined as follows:Salix J172> Salix J369> Salix J194> Salix sonjarica> Salix bylonica > Populus gansuensis C.Wang et H.L. Yang> Populus alba L.var.pyramidalis Bge > Populus hopeiensis Hu et Chow > Populus BT85> Populus B1008.

Key words: analytical hierarchy process (AHP), evaluation of optimum choice, tree species, farmland protection forest
