通过对生态旅游资源与生态旅游商品的关系、以及生态旅游商品的价值和价格的分析,认为生态旅游商品的主体是自然资源,它是生态旅游商品价值构成的主体,也应该是构成生态旅游商品价格的主体。而传统的旅游价格构成理论不能完全释义现代的生态旅游商品价格构成。在现行旅游商品的价格理论指导下,导致生态旅游商品的理论价格和操作价格中的价值主体错位,直接影响到生态旅游的可持续发展。

Arundo donax Linn.was selected as representation of giant grass.The main growth factors,planting materials and soil texture were analyzed by several spot experiments in Beijing.The result showed that A.donax was able to endure drought and leanness.The survival rate was above 85%.It grew normally in the soil where the organic matter level was 0.413%.Moreover,depending only on precipitation,A.donax grew with high biomass.The overwintering survival rate of A.donax increased significantly if some protection measures were taken,and harvesting in March of next year was one of the most feasible measures.
