The results show that the suitable areas （which contain highly suitable, generally suitable, and critically suitable areas） for R. damascena trigintipetala are 307.268×lO4 hm^2, which accounts for 6.34% of the total provincial area. Results also indicate that shrub land and open forest land are the major land-use types suitable for R. damascena trigintipetala, with the suitable areas of 303.162×lO4 hm2 （6.25% of the total provincial area）. An introduction test was conducted in one of the suitable areas, Xichang City, which demonstrated that R. damascena trigintipetala grows well at theexperimental sites. The quality of rose oil extracted from R. damascena trigintipetala planted in Xichang meets the Bulgaria Rose Oil Standard, thus verifying the accuracy and reliability of the ecological suitability assessment results.展开更多
