The Use Of Forest Resources In Xiaoxing'anling Mountains Was Influenced Spatial And Temporal Scales And Food Resources On Black Bear Habitat

Black bears are an important component of Bear Resources in China, and is also the one of Northeast China forest typical of large forest-dwelling animals, in our temperate forest ecosystems play an important ecological role. Select the main forest areas in Xiao xing'anling Mountains in northeastern China to study. Use of forest resources is forest harvesting berries, nuts, wild vegetables collected. Because of forest harvesting utilization of forest products in Xiaoxing'anling Mountains, resulting in a change in black bear habitat selection, black bear food resources are affected in varying degrees too. And Different forest resource utilization, different use of forest resources from the investigation time, the black bear habitat and food resources for both spatial and temporal scales influence. Application of wildlife survey techniques and 3S technology and utilization of forest resources files to study black bear habitat in Xiaoxing'anling Mountains, different harvesting time and forest by-products of the different times and different types of existing biomass, analysis the impact of habitat and food resources and spatial and temporal changes of black bear. Thus, reveal the black bear habitat and food resources of time and space is changed by the use of forest resources in Xiaoxing'anling Mountains, for provide scientific basis and conservation and management of proposed black bear habitat and protection and management of sustainable development theory, for the black bear habitat.Application of resource selection function and the resource selection index was used to study for black bear habitat selection in Ula muddy forestry in Tong he County. The results show that:Habitat selection of Black bear was influenced by the water, fallen trees, terrain factors and conditions hidden factors. The black bear is fond of the habitat that is higher altitude(>350m) and located on the uphill location and moderate gradient. The resource selection functions of selection of black bear is:Logistic(p)=-5.254+8.644*Slope+l.896*Slop-e position+2.728*Hidden class+4.626*Canopy-1.795*Geographic-14.901*Distance to water +2.356*Distance to Interference+6.078* fallen trees+2.138* Tree species. Black bear habitat selection probability is:P=eLogistic(p)/[1+eLogistic(p)]. Correct rate of the model was 96.2%.Application of resource selection function and the resource selection index was used to study for black bear habitat selection in the results show that:habitat selection of Black bear was influenced by the water, fallen trees, terrain factors and conditions hidden factors. The black bear is fond of the habitat that is higher altitude(>350m) and located on the uphill location and moderate gradient. The resource selection functions of selection of black bear is Logistic(p)=-0.0832+1.678*Altitude+1.593*Vegetation type-4.276* Slope position+2.120* Aspect+1.755* Hidden class+0.521* Canopy-2.810* Distance to water-3.636* Distance to Interference+1.205*Tree species+0.085*Shrub+1.494*Herb cover+1.818*fallen trees.Black bear habitat selection probability is:P=eLogistic(p)/[1+eLogistic(p)].Correct rate of the model was76.5%.
