广西元宝山自然保护区黑熊春季觅食生境特征
Spring foraging habitat character of black bear(Ursus thibetanus)in Guangxi Yuanbaoshan Nature Reserve
摘要
Abstract
From Jan 2009 to March 2009, black bear's foraging habitat character in Yuanbaoshan Nature Reserve of Guangxi was studied. In fieldwork, we collected 82 samples (20 m x20 m), sixteen ecological factors. Principal components analyses results showed that main factors of black bear foraging habitat characteristics were water distance, elevation, and shrub density; secondary factors were food abundance factor (tree diameter, tree density, tree distance, shrub distance) ,geographical factors (aspect, slope position, ratio of slope) .interference factors (tree stump density, tree stump distance, log distance, human disturbance distance) , and micro-habitat factors (shelter of wind, canopy density). Single factor analyses indicated black bear priorities were water richness, certain altitude., moderate shelter of wind,vegetation richness (tree density, shrub density, shrub distanceNtree distance),aspect towards sun,canopy density (30 % -80 % ),ridge steep slope and optimal slope position habitat. As human activity increase, interference factors (tree stump density, tree stump distance, log distance, distance to human disturbance) were important factors which influence black bear habitat selection. Our conclusion provide important information for Nature Reserve and forest management department.关键词
