引用

Journal of Geoscience and Environment Protection 2025年第1期13卷 89-102页

作者： Yuanyuan Wang Mei Wang Nuosi Li Xinya Zhou Youyou Huang key laboratory of southwest China Wildlife Resources conservation (Ministry of Education) China West Normal University Nanchong China

After the Wenchuan earthquake on May 12, 2008 and the rainstorm and debris flow on August 14, 2010, the vegetation in Hongchun Gully, Yingxiu town is gradually recovering naturally, and the plant community is gradually undergoing community succession. Based on the field vegetation survey data of 46 quadrats in 5 field plots, this study comprehensively analyzed the plant community, species number changes and vegetation characteristics of Hongchun Gully in Yingxiu town at different stages of vegetation succession after the earthquake by using the unified method. The results show that: 1) There are 61 families, 96 genera and 110 species of plants on the Hongchun Gully landslide. Among them, Cunninghamia lanceolata is the most widely distributed, and together with Cryptomeria japonica, it constitutes the main dominant species in the tree layer;The dominant species in shrub layer are Rubussp., Hydrangea strigosa, Rubus tephrodes, etc. The dominant species in herb layer are Artemisia argyi, Stellaria media and Senecio scandens. 2) The vegetation restoration in Hongchun Gully is relatively good, with herbs as the main species in the early stage of succession, shrubs and herbs as the main species in the middle stage of succession and trees as the main species in the late stage of succession;And the longer the succession time, the better the vegetation restoration and the richer the species. 3) Vegetation succession is related to the succession time, and the succession is always in the direction of strong adaptability. The study provides important data reference for further discussing the natural restoration and succession process and mechanism of plant communities on the damaged landslide formed after the earthquake, and provides theoretical basis for vegetation restoration and ecological reconstruction in the hardest hit areas in southwest China after the earthquake.

Beyond amplitude: Phase integration in bird vocalization recognition with MHAResNet

Avian Research 2025年第01期 119-128页

作者： Jiangjian Xie Zhulin Hao Chunhe Hu Changchun Zhang Junguo Zhang School of Technology Beijing Forestry University State key laboratory of Efficient Production of Forest Resources Beijing Forestry University key laboratory of National Forestry and Grassland Administration on Forestry Equipment and Automation Research Center for biodiversity Intelligent Monitoring Beijing Forestry University

Bird vocalizations are pivotal for ecological monitoring, providing insights into biodiversity and ecosystem health. Traditional recognition methods often neglect phase information, resulting in incomplete feature representation. In this paper, we introduce a novel approach to bird vocalization recognition(BVR) that integrates both amplitude and phase information, leading to enhanced species identification. We propose MHARes Net, a deep learning(DL) model that employs residual blocks and a multi-head attention mechanism to capture salient features from logarithmic power(POW), Instantaneous Frequency(IF), and Group Delay(GD) extracted from bird vocalizations. Experiments on three bird vocalization datasets demonstrate our method's superior performance, achieving accuracy rates of 94%, 98.9%, and 87.1% respectively. These results indicate that our approach provides a more effective representation of bird vocalizations, outperforming existing methods. This integration of phase information in BVR is innovative and significantly advances the field of automatic bird monitoring technology, offering valuable tools for ecological research and conservation efforts.

Incorporating topographic factors in nonlinear mixed-effects models for aboveground biomass of natural Simao pine in Yunnan,China

引用

Journal of Forestry Research 2016年第1期27卷 119-131页

作者： Guanglong Ou Junfeng Wang Hui Xu keyi Chen Haimei Zheng Bo Zhang Xuelian Sun Tingting Xu Yifa Xiao key laboratory of biodiversity conservation in southwest China of State Forest Administration Southwest Forestry University

A total of 128 Simao pine trees （Pinus kesiya var. langbianensis） from three regions of Pu＇er City, Yunnan Province, People＇s Republic of China, were destructively sampled to obtain tree aboveground biomass （AGB）. Tree variables such as diameter at breast height and total height, and topographical factors such as altitude, aspect of slope, and degree of slope were recorded. We considered the region and site quality classes as the ran- dom-effects, and the topographic variables as the fixed- effects. We fitted a total of eight models as follows： least- squares nonlinear models （BM）, least-squares nonlinear models with the topographic factors （BMT）, nonlinear mixed-effects models with region as single random-effects （NLME-RE）, nonlinear mixed-effects models with site as single random-effects （NLME-SE）, nonlinear mixed-ef- fects models with the two-level nested region and site random-effects （TLNLME）, NLME-RE with the fixed-ef- fects of topographic factors （NLMET-RE）, NLME-SE with the fixed-effects of topographic factors （NLMET-SE）, and TLNLME with the fixed-effects of topographic factors （TLNLMET）. The eight models were compared by modelfitting and prediction statistics. The results showed： model fitting was improved by considering random-effects of region or site, or both. The models with the fixed-effects of topographic factors had better model fitting. According to AIC and BIC, the model fitting was ranked as TLNLME 〉 NLMET-RE 〉 NLME-RE.〉 NLMET-SE 〉 TLNLMET 〉 NLME-SE 〉 BMT 〉 BM. The differences among these models for model prediction were small. The model pre- diction was ranked as TLNLME 〉 NLME-RE 〉 NLME- SE 〉 NLMET-RE 〉 NLMET-SE 〉 TLNLMET 〉 BMT 〉 BM. However, all eight models had relatively high prediction precision （〉90 %）. Thus, the best model should be chosen based on the available data when using the model to predict individual tree AGB.
