    A Framework for Developing Biodiversity Conservation Networks Based on Morphological Spatial Pattern Analysis and the Maximum Entropy Model: A Case Study of the Jianghan Plain, Chi... by Xiaohua Guo, Chang Liu, Shibo Bi, Xuewen Zhang

    Published 2025-01-01
    “…Our findings indicated the following: (1) The Jianghan Plain hosts 21 major ecological sources, primarily natural water bodies at the plain’s edge, which can be classified into five primary and 16 secondary sources based on biodiversity grades. (2) The recessive corridors, comprising 10 primary and 95 secondary ones, are mainly concentrated in the central Jianghan Plain, with primary corridors located centrally and westward, characterized by a large overall span. (3) Changhu Lake and Honghu Lake, two critical water bodies with high-quality habitats and significant biodiversity, were identified as key ecological nodes from the ecological sources, bridging and guiding the central and southern corridors. (4) Based on the ecological network distribution and key nodes and corridors, a “three zones, three belts, and two points” strategy was proposed for optimizing the Jianghan Plain’s ecological network. …”

    Study on the Annual Variation Characteristics of Runoff in Yunnan by GU Guihua, LI Xuehui, YU Shoulong, DUAN Lusong

    Published 2021-01-01
    “…To study the annual variation characteristics of runoff in Yunnan Province and analyze the main influencing factors,based on the observed monthly and annual rainfall and runoff data of 9 representative hydrological stations in 6 major river basins in Yunnan from 1956 to 2016,this paper analyzes the annual runoff distribution in terms of the uniformity,concentration and relative variation range.The research shows that:①The uniformity coefficient (C<sub>u</sub>) of runoff distribution in many years ranges from 0.55 to 1.21,and the concentration (C<sub>n</sub>) ranges from 0.23 to 0.66,so the runoff is unevenly distributed in the whole province.②The C<sub>u</sub> and C<sub>n</sub> decrease in general.Especially after 2000,the annual distribution of runoff shows a trend of uniformity.③The runoff concentration is relatively high in the Yangtze River Basin and the Honghe River Basin,and the annual runoff distribution is flat in the Lancang River Basin and the Zhujiang River Basin.④The uniformity trend of annual runoff distribution is closely related to human activities in the basin.…”

    Efficient Spectral-Spatial Fusion With Multiscale and Adaptive Attention for Hyperspectral Image Classification by Xiaoqing Wan, Feng Chen, Weizhe Gao, Yupeng He, Hui Liu, Zhize Li

    Published 2025-01-01
    “…Extensive experiments conducted on four public datasets (Houston2013, Botswana, WHU-Hi-HanChuan and WHU-Hi-HongHu) demonstrate that the proposed ESSF method significantly outperforms nine other state-of-the-art methods in terms of classification accuracy.…”

    Impacts of Intensified Agriculture Developments on Marsh Wetlands by Zhaoqing Luan, Demin Zhou

    Published 2013-01-01
    “…A spatiotemporal analysis on the changes in the marsh landscape in the Honghe National Nature Reserve, a Ramsar reserve, and the surrounding farms in the core area of the Sanjiang Plain during the past 30 years was conducted by integrating field survey work with remote sensing techniques. …”
