摘要：
Under Metaverse, security management of communication networks in digital cultural consumption has attracted more and more attention. As we know, security risks of communication networks caused by non-human factors are becoming weaker and weaker due to technology optimization. Meanwhile, play-ers play significant and increasing role in communication networks. Taking mobile games as an example, this paper designed and applied the security management model to improve security management of communication networks in digital cultural consumption under Metaverse. The results show that: (1) The physiological, psychological, pathological, pharmacological, physical and psychosocial factors exert tremendous influence on communication networks. The psychosocial factors are more prominent. (2) There is security threshold in communication networks. It means that the security state can be entered if security threshold is crossed. This paper designs security threshold as the III level (5.5 <= P < 6.5). (3) This paper proposes 3E rules (That is, engineering, education, enforcement). It is beneficial to deal with security risks in communication networks. (4) After two security evaluations, the result is G2 = 6.70 > G 1 = 5.01. This confirms the effectiveness of the security management model.(c) 2023 Published by Elsevier B.V. on behalf of Faculty of Computers and Information, Cairo University.

摘要：
The availability of very high spatial resolution (VHR) remote sensing imagery provides unique opportunities to exploit meaningful change information in detail with object-oriented image analysis. This study investigated land cover (LC) changes in Shahu Lake of Wuhan using multi-temporal VHR aerial images in the years 1978, 1981, 1989, 1995, 2003, and 2011. A multi-resolution segmentation algorithm and CART (classification and regression trees) classifier were employed to perform highly accurate LC classification of the individual images, while a post-classification comparison method was used to detect changes. The experiments demonstrated that significant changes in LC occurred along with the rapid urbanization during 1978–2011. The dominant changes that took place in the study area were lake and vegetation shrinking, replaced by high density buildings and roads. The total area of Shahu Lake decreased from ~7.64 km<sup>2</sup>to ~3.60 km<sup>2</sup>during the past 33 years, where 52.91% of its original area was lost. The presented results also indicated that urban expansion and inadequate legislative protection are the main factors in Shahu Lake's shrinking. The object-oriented change detection schema presented in this manuscript enables us to better understand the specific spatial changes of Shahu Lake, which can be used to make reasonable decisions for lake protection and urban development.<br/> 2018 by the authors.
