Study on Effects of Forest Management Interference on Succession Trend of Larix principis-rupprechtii Plantation
摘要
Abstract
[Objective] The study aimed to provide the basis of optimizing the structure of plantation community of Larix ptindpis-rupprechtu and scientifically managing the existing L principis plantation. [ Method ] The L principis plantation with different management measures in Weichang County of Hebei Province were conducted for the vegetation investigation through setting the sample land and make for the analysis on its succession trend. [ Result ] The relative density of main forest layer for the community of A, B, C, D all were 100.00% and that of suc cession layer and update layer were 87.79% and 4. 10% resp. The relative density of main forest layer for the community E was 8. 10% and that of succession layer and update layer were 0.00% , resp. The relative density of main forest layer for the community F was 76. 69% and that of succession layer and update layer were 12.53% and 10.78% , resp. [ Conclusion ] L principis plantation on which there was no man agement interference or there was only thinning in long time showed an obvious succession tendency and still continued in the condition of the single-layer pure forest in the short term. The community whose surface litter were cleaned after thinning might develop into the main forest layer with the existing big trees of L principisi. L principis and few Betula platyphylla etc. Which won the competition in succession and up date layer might develop into the multiple layer uneven aged forest of sub-forest layer. L. Principis plantation on which there was less interfer ence should be develop into the multiple-layer uneven-aged mixing forest with L principis as an advantage specie, B. Platyphylla as an sub advantage specie and other broad-leave tree species as the accompanying species.关键词
