After observation and analysis on 3 complex planting models of eco-economic forest in Jinsha river hot-dry valley,it shows,the 3 complex planting models' economic production-invest ratio and land production relation is: Longyan Taiwan Green Jujube>Longyan Rose Geranium>Longyan Monoculture.The Longyan Taiwan Green Jujube model is best,the two index of it are 1.6 and 3.3 times to Longyan monoculture.The biomass and correlative indexes of Longyan Rose geranium model are higher than the other 2 model.Each model has regulate function to local microclimate,and the effect is Longyan Taiwan Green Jujube>Longgan Rose Geranium>Longyan monoculture.As to the soil improvement effect,the Longyan Rose Geranium model obviously excel the two other models.Synthetically analyze the 3 models eco-economic benefit,the Longyan Taiwan Green Jujube and Longyan Rose geranium models are better than Longyan monoculture.
