摘　　要：我国横断山区有自然资源丰富 ,农业发展潜力大的优势 ,但生态环境退化 ,农业产业结构不合理。等高固氮植物篱技术在水土保持、土壤培肥、饲养牲畜、发展蚕桑、生产烤烟、供给薪柴和沼气、恢复植被、综合利用农业土地资源等方面良好的作用和效果 ,可作为横断山区调整农业产业结构的有效措施 ,并可在农业可持续发展中发挥重要作用。. Having plentiful natural resources and large potential in agricultural developing are intersecting mountain area's predominance in our country, but it has degenerate ecological environment and unreasonable agricultural industrial structure too. Nitrogen fixing plant fence having accordant heights has favorable role and impact on soil conservation, increasing soil fertility, raising livestock, developing Morus alba for silkworm, producing cured tobacco, supplying fuel wood and methane, restoring vegetation, agricultural land resource's complex utilization, etc, so it can be accepted as adjusting agriculture industrial structure's effective measures in intersecting mountain area and plays a important role in agricultural sustainable development.
