This paper described crucial techniques for establishment of stable industrial poplar timber forest with fast growth,high yield,high profit and good quality. Based on analysis of site condition, species selection,proper density, optimum rotation age and forest management, siviculture technical standards were founded. The conclusion is: for large-sized timber,proper density of poplar forest is 200-300 trees/hm 2 and rotation age 12-15 years; for medium-sized timber, density 300-600 trees/hm 2 and rotation age 9-11 years; for under-sized timber, density 600-1100 trees/hm 2 and rotation age 6-8 years.
