广元飞播造林成效与流域生态环境效益研究

Study on the Effect and Ecological Environment Benefit of Afforestation by Aerial Seeding in Guangyuan

运用川北广元历年飞播成效调查以及固定标准地观测的结果，结合笔者从事飞播造林技术与管理工作的经验，得出：飞播造林是速度快、省劳力、投资少、成本低、效益高的造林方式，推广飞机播种造林是绿化川北山地。

Expriences gained from afforestation by aerial seeding in Guangyuan proves that afforestation by aerial seeding is a fast,labour-saving ,low cost and high beneficial way of afforestation,and of achieving sustainable development,and protecting ecological environment in the Northern Sichuan Mountainous Area
