| 摘 要： | 本研究利用遥感和GIS技术,分析盐城自然保护区1983–2018年的景观格局变化,建立了基于区域自然-社会-经济复合生态系统安全格局的评价指标体系,分析了生态安全变化的空间特征和成因。结果表明,1983–2018年由于人类活动加剧,研究区内景观格局变化强烈,从以自然景观为主发展到自然景观与人工景观并存。在整体生态安全方面,目前保护区的生态安全状况不容乐观,从保护区丹顶鹤的生存状态看,保护区总体上还是适宜丹顶鹤栖息的,但由于人类活动的增加以及政策的调整,丹顶鹤的栖息地呈现破碎化并向核心区和缓冲区等局部区域聚集。我们应从管理、政策制定以及当地居民的环境保护意识上增加宣传和投入,并相应减少保护区内人类活动的强度。

| Abstract: | This study used remote sensing and GIS to analyze the landscape pattern changes in the Yancheng Nature Reserve from 1983 to 2018,established an evaluation index system based on the regional natural-socio-economic complex ecosystem security pattern,and then analyzed the spatial characteristics of ecological security changes and discusses reasons for these changes.The results show that the landscape pattern changed dramatically from natural landscape to a mixture of natural landscape and artificial landscape from 1983 to 2018 due to the intensification of human activities.At present,the ecological security status of the protected areas is not optimistic.From the perspective of the survival status of red-crowned cranes,the protected areas are suitable.However,due to the increase of human activities and policy adjustments,the habitat of red-crowned cranes is fragmented.The red-crowned crane currently gathers in localized areas such as the core area and the buffer zone.We should pay more attention to management,policy development and the environmental awareness of local residents.At the same time,it is necessary to reduce the intensity of human activities within the reserve. |
