低效低质人工林优化改造后林下植被多样性研究
Understory biodiversity of managed plantation stands from the inefficient and inferior forests
摘要
Abstract
The understory biodiversity was studied using ground plot investigation for eleven managed plantation stands from inefficient and inferior forest and one natural secondary stand (control). As a result, there were 55 species on all 12 plots, ranging from 11 to 23 species. The most commonly happened species were Altaicus (Willd.) Novopokr., Ddavurica (Laxm.) Schindl., Capillata Linn., Vestita Wall, ex Bess., Chinensis Ser. The dominant species were Secalinus (Georgi) Tzvel, Vestita Wall, ex Bess., Davurica (Laxm.) Schindl., Giraldii Pomp., Capillaris Thunb., Lavandulaefolia DC. There were significant difference in biodiversity between plots. The variation tendency of Gleason index was consistent with that of FIE index, Simpson index and Fielou evenness index was opposite to Gleason and PIE. There was no apparent variation in Shannon-Wiener Index. It was suggested that the biodiversity of plantation stands was influenced by stand age, density, and compositioa The biodiversity of plantation stand was poorer than natural forest.关键词
