基于无人机激光点云的树障检测与砍伐树木数量估算

电力走廊的树木生长会对输电线路的安全运营造成巨大影响,精确检测出影响线路安全的树木并将其砍伐至关重要。因此,提出一种基于无人机激光点云的树障检测与砍伐树木数量估算方法。首先,对激光点云进行快速自动化处理,先后精确提取地面点、电力线点与植被点;其次,基于电力线点进行分段,并分析电力线与植被点的安全距离,进而确定树障区域的位置和范围;最后,对树障区域植被点云进行单木分割,并统计单木数量,最终实现砍伐树木数量的精准估算。研究结果表明,无人机激光点云可以实现输电通道树障的有效检测与砍伐树木数量的精确估算,总体树木砍伐数量估算精度可达92.3%,可为输电线路安全运营提供遥感技术支撑,也可为电网运维单位制订树木砍伐计划提供可靠依据。     

魏徵政论的历史底蕴

魏徵是唐太宗统治集团中的主要决策人物之一,其政治活动表明,他既是一个谙于当代政事的史论家,又是一个富有历史感的政论家。魏徵之所以被史家誉为"雅有经国之才",同他在这两个方面的修养有密切的关系。魏徵政论的历史底蕴,是他的政治敏感和历史智慧相结合的表现,也是他的诤谏风格的突出特点。史学和政治的关系,在魏徵那里,实际上也就是古今关系的反映。     

新闻故事化趋向的隐患分析

当前我国新闻报道的故事化趋向已经被业界所认可。但是这种趋向使新闻报道更具人情味、趣味性的同时，也使当前的新闻报道存在失实报道增多，流于浅薄，屏蔽重大社会事件，更易于渗入记者的主观情绪等隐患。

The Fallacy of Misplaced Concreteness: Its Importance for Critical and Creative Inquiry

In Science and the Modern World, Alfred North Whitehead (1925/1953) critically discusses the historical development of science and its larger impact on our civilization and culture today. The fallacy of misplaced concreteness (FMC) is a notion central to his analysis, both of the process of inquiry and to the general sustainability of quality of life. This paper is part of a panel of four presentations relevant to the theory, practice, and teaching of science. In this paper I identify the FMC as a set of variations on the central theme of misplacing concreteness, by mistaking the abstract for the concrete, and I define the component notions involved. More than half of the paper involves a representative range of concrete examples of the FMC. The realm of the aesthetic, of patient and sensitive attention, the full range of immediate bodily feeling, and the variety of real values revealed therein, turns out to be both the victim of and the remedy for the FMC. As Whitehead says: "Sensitiveness without impulse spells decadence, and impulse without sensitiveness spells brutality" (1925/1953, p. 200).     

How to sustainably increase students’ willingness to protect pollinators

The current loss of biodiversity requires efforts to increase awareness of pollinator conservation. An important tool is education which often uses the honeybee (Apis mellifera) as an exemplary organism to reach this goal. Any successful module needs to focus on reducing the perceived danger associated with fear, in order to support the willingness to protect them. Using a quasi-experimental design, we investigated the effectiveness of two educational approaches: one by authentically encountering living animals at a beehive, the other by using a remote online beehive. We monitored secondary school students’ (N = 354) perception of bees with respect to interest, danger and conservation as well as situational emotions (interest, well-being, boredom) during both interventions. In both cases positive effects on perception levels were observed, even when already a high willingness to protect bees existed. Using living animals in educational settings is crucial, especially when students’ situational emotions need targeting. However, we achieved similar intervention results in perception levels using a remote beehive, which therefore constitutes an excellent alternative to raise awareness of the conservation of bees as pollinators when working with living organisms is not possible.
