The World Natural Heritages, Jiuzaigou and Huanglong, are located in the eco-fragile areas of West China. Since 2001, 12 repairing models of degraded landscape in the eco-fragile areas were implemented in Songpan County, i.e., Lycium chinense, Hippophae rhamnoi des, Amygdal us davidiana + Picea as perata, Armeniaca sibirica + P.asperata , P.asperata, Syringa komarowii + Malus kansuensis, P. asperata + Salix argentinensis, P.asperata + Populus cathayana, S .argentinensis, S .argentinensis + P.cathayana, P.cathayana, and A.sibirica + S.argent inensismodels. This paper analyzed both horizontal and vertical species diversity in the 12 models. Results showed there were generally poor species richness and diversity in woody layer. On the contrast, herb layer of most models possessed considerable diversity, along with about 20 species and Shannon-Weiner index over 2.0. Further, most models possessed sound species diversity, contributed by diversity in herb layers. Most models possessed sound species diversity indexes and diversity between models was also greater. With the developing of diversity, it is helpful to constructing a stable and healthy ecosystem and establishing a material foundation for developing to further stage
