大兴安岭火烧迹地植被恢复后物种多样性及其与土壤环境的关联分析
Plant Species Diversity and Correlation with Soil Factors After Vegetation Restoration in Burned Area of Great Xing′an Mountains
摘要
Abstract
The correlation between biodiversity and soil physiochemical properties were analyzed under four stand types in Great Xing′an Mountains,which were restored since burned in 1987,using the gray relational analysis.The results showed that the biodiversity varied substantially among four different stands,demonstrating a descending order of biodiversity as Pinus sylvestris var.mongolica plantationLarix gmelini plantationPobulus davidiana natural forestBetula platyphlla natural forest.The soil physical and chemical properties also varied;Pinus sylvestris var.mongolica plantation was found under the poorest condition.The grey relational coefficient between biodiversity and soil environment exceeded 0.5 for all the four stands,showing different correlations.Shannorr—Wiener index,evenness index and species richness index correlated closely with soil bulk density under Pinus sylvestris var.mongolica plantation and Pobulus davidiana natural forest,whilewith non-capillary porosity under Larix gmelini plantation and Betula platyphlla natural forest.The three indices were also found correlated closed with available phosphorus under the Pinus sylvestris var.mongolica plantation,Larix gmelini plantation and Betula platyphlla natural forest,except for Pobulus davidiana natural forest.关键词
