| Abstract: | Based and on a detail approach to the PM of shelterbelt on the growth pattern of it, the methods for determining PM and regeneration ages(RA) are established. Initial protective maturity age (IPMA) and RA of 5 poplar species shelterbelts such as Populus beijingensis, P. xiaozhuanica ect. are determined as the examples. Meanwhile, benefit evaluation in different regeneration patterns is also made in this paper. |
