摘　　要：通过对半干旱退化山区生态经济型防护林体系营建与配置,优化了林种和树种结构,改变了树种单一局面,提出了不同立地条件的人工混交林,试区已形成了以防护林为主的多林种、多树种、多层次结构,带、片、网、团、乔、灌、草相结合的生物学稳定的人工生态系统。同时已建成面积为1 200 hm2持续、高效的生态经济型防护林体系建设模式示范区,为生态经济型防护林体系建设提供了科学依据和途径。Through building and allocating ecology-economy protective forest system in the semi-arid degenerated mountainous area, forest species and the tree species structure were optimized, the tree species sole aspect was changed, and the artificial mixed forest of different growth condition was also proposed. The stable artificial ecosystem has formed which has a structure of multi-forest species（mainly by protective forest）, multi-tree species, multi-level and integration of the belt, the piece, the net, the group, tall, shrubbery and the grass. At the same time, the area of the highly effective ecology-economy protective forest system model district of 1 200 hm^2 was completed,which provided scientific basis and the way for the ecology-economy protective forest system construction.
