摘    要:通过对金沙江干热河谷生态经济林的3种典型复合种植模式的观测分析,结果表明,3种复合种植模式的经济产投比、土地生产率的关系为:龙眼+台湾青枣模式〉龙眼+香叶天竺葵模式〉龙眼单作模式。其中龙眼+台湾青枣模式最高,2项指标为龙眼单作模式的1.6和3.3倍。龙眼+香叶天竺葵模式的生物量及其相关指标高于其它2种模式。各模式对局地小气候都有一定的调节作用,其中龙眼+台湾青枣模式〉龙眼+香叶天竺葵模式〉龙眼单作模式。从对土壤改良效应来看,龙眼+香叶天竺葵模式明显优于其它2种模式。综合3种模式的生态经济效益分析,龙眼+香叶天竺葵模式和龙眼+台湾青枣模式优于龙眼单作模式。

关 键 词:金沙江干热河谷  生态经济林  效益研究

Abstract: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.
Keywords:Jinsha river hot-dry valley  ecological economic forestry  benefit study
