A Simplified Approach for Interpreting Principal Component Images

引用

Advances in Remote Sensing 2013年第2期2卷 111-119页

作者： Ravi P. Gupta reet k. tiwari Varinder Saini Neeraj Srivastava Department of Earth Sciences Indian Institute of Technology Roorkee Roorkee India PLANEX Physical Research Laboratory Ahmedabad India

Principal component transformation is a standard technique for multi-dimensional data analysis. The purpose of the present article is to elucidate the procedure for interpreting PC images. The discussion focuses on logically explaining how the negative/positive PC eigenvectors (loadings) in combination with strong reflection/absorption spectral behavior at different pixels affect the DN values in the output PC images. It is an explanatory article so that fuller potential of the PCT applications can be realized.

尼泊尔Chitwan国家公园人类-大型食肉动物冲突的模式、原因和感知（英文）

人与野生动物尤其是大型食肉动物之间不断加剧的冲突是保护区面临的主要管理问题之一，食肉动物对牲畜的损害和对人类的袭击造成的人员伤亡是管理中面临的严重挑战。本研究旨在探索Chitwan国家公园纳瓦尔普尔地区人类与大型食肉动物冲突的模式、成本、原因和感知。利用2001年-2019年报告给Chitwan国家公园的数据分析了大型食肉动物（虎和豹）对牲畜损失和人员伤亡的方式。为了了解人们对食肉动物和野生动物保护的看法，我们询问了150名受害者，每个格网选择一个家庭代表。在研究的19年期间，共报告了由大型食肉动物引起的521起冲突事件，其中包括33起人员伤亡和488起牲畜损害。虎在纳瓦尔普尔地区造成的冲突事件最多。Chitwan国家公园当局在纳瓦尔普尔地区提供的人员死亡和伤害救济总额为17524.41美元，用于赔偿牲畜损害的总额为13702.18美元。尽管食肉动物对牲畜损害、人员伤害和死亡负有责任，但仍有超过64%的受访者喜欢食肉动物在他们所在地区的存在，并对大型食肉动物保护持积极态度。人们对政府提供的救济计划的满意程度取决于种族、性别、年龄、职业、教育、保险和牲畜所有权，但他们认为该计划并不很有效。因此，应在冲突地区开展有效的救济计划和宣传活动，提高人们对救济资金使用方式的认识。向当地社区开展关于大型食肉动物及其行为的宣传活动，并准备防损围栏，有助于减少研究区域的冲突。
