摘　　要：对黑龙江省西部半干旱风沙区生态经济型防护林模式进行了试验构建与筛选,结果表明:樟子松、红皮云杉单行及双行林带配置经济树种模式中,带外株间配置较带内株间及带内行间配置成活率高,且随着林带树龄的增大,配置经济树种的成活率明显降低,林带中生态树种树龄以不超过15 a为宜;而针对不同类型区在防护林生育早期可分别间作经济作物或中草材来提高其经济效益,提高单位面积土地生产力,从而增强了生态型防护林的经济功能;杨树林带与食用菌栽培有机结合可明显提高林带的短期经济效益,又促进了林木生长,是一种较为理想的生态经济型防护林模式类型。Eco-economic sheherbelts model in semiarid sandy areas of western Heilongjiang province were constructed ＆ selected. Result shows that： in the models of economic species for Pinus sylvestris var. mongolica ＆ Picea koraiensis with sin- gle ＆ dualline shelterbelt arangement, survival rate of strain arrangement outside the shelterbelt are higher than that of interplant ＆ row arrangement inside the shelterbelt;survival rate of arrangement with ~conomic trees decreases significantly with the increase of tree age of stand;tree age of ecological species in the stand is appropriately not over 15 years;different types of areas in early growing stage could be intercropped with economic crops ＆ Chinese medicine herb, that can improve land productivity per unit area, thereby enhancing the economic function of ecological protection forest;poplar combined with mushroom cultivation not only can significantly increase the forest＇ s short-term economic benefits, but also promote tree growth,which is an ideal eco-economic protection forest model type.
