Effects of Different Forest Management Model on Undergrowth Vegetation of Larix Principis-rupprechtii Plantations
[Objective] The objective was to find out health management of Larix principis-rupprechtii plantation under different forest age and to evaluate the effects of management conducted at present.[Methods]The study was carried out in Wangyedian forest farm of Chifeng City in Inner Mongolia. The coverage
diversity index and biomass were chosen as the indicators of vegetation condition. The impacts of conventional management and close-to-nature forest management on undergrowth vegetation of Larix principis-rupprechtii plantation were assessed by taking the no disturbance forest management as reference.[Results] (1) At young forest stage
no disturbance management was found good for the development of diversity of undergrowth vegetation
and conventional management was proved beneficial to gain maximum biomass; (2) The diversity of undergrowth vegetation of no disturbance management had its maximum at half-mature forest stage
and the vegetation type
coverage
biomass of undergrowth vegetation of close-to nature forest management were the maximum; (3) At near-mature stage
vegetation type
coverage
diversity index and biomass of undergrowth vegetation were all larger than those of no disturbance management and conventional management.[Conclusion] Measures suitable to the stand age
management aim should be made in Larix principis-rupprechtii plantation management.
