Eco_environment evaluation aims to calculate the eco_environment synthesis exponent according to the weight of some indexes.The author explained the theory foundations of principal component synthesis evaluation method,and made practical applications in mid_Tibet eco_environmental quality evaluation.Results show that the close relations is apparently altitudinal zonality in the eco_environmental quality;the better quality of Ⅶ,Ⅷ classes mainly distribute in the valley and plain,and the worse quality of Ⅰ,Ⅱ classes mainly distribute in the high mountain.
