基于多源遥感的大熊猫国家公园光污染时空动态与生态边缘效应
Spatial and Temporal Dynamics of Light Pollution in Giant Panda National Park based on Multi-source Remote Sensing and Ecological Edge Effects
[目的]保护地和荒野地区越来越多地受到光污染的侵蚀。大熊猫国家公园作为中国南北跨度最大的国家公园,评估其光污染并探索特征,对生物多样性保护、国家公园管理和可持续发展具有积极价值。因此,本研究分析了过去 30 年间大熊猫国家公园光污染变化的时空趋势;评估了人类活动和土地开发强度是否影响会大熊猫国家公园光污染。[方法]本研究使用夜间卫星遥感影像的平均夜间辐射强度来评估光污染水平;基于景观生态学方法测量景观指数以评估光污染特征;计算公园内和公园外 10…查看全部>>
[Objective]Protected and wild areas are increasingly encroached upon by light pollution.Giant Panda National Park,the largest national park spanning from north to south in China,assesses its light pollution and explores characteristics that are of positive value for biodiversity conservation,national park management,and sustainable development.Therefore,this study analyzed the spatial and temporal trends of light pollution changes in Giant Panda National Par…查看全部>>
