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。After observation and analysis on 3 complex planting models of eco-economic forest in Jinsha river hotdry 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 mieroelimate, and the effect is Longyan ＋ Taiwan Green Jujube〉 I.onggan ＋ Rose Geranium〉 Longyan monoeulture. As to the soil improvement effect, the Longyan ＋ Rose Geranium model obviously excel the two other models. Synthetically analyze the 3 models eeo-eeonomie benefit, the Longyan＋Taiwan Green Jujube and Longyan＋Rose geranium models are better than Longyan monoculture.
