国外B＆B与我国“农家乐”的比较研究

经过20年来的发展,我国的“农家乐”如今已初具规模,但仍然存在不少问题。而国外的B＆B发展经验可以为我国“农家乐”的发展提供借鉴。通过比较分析,本文认为我国“农家乐”的进一步发展．需要做两方面的努力：一方面,“农家乐”业主应组织起来,走企业化经营之路,并采用整合营销策略：另一方面,政府对“农家乐”实行分级制度,并给与相应的税收及扶持政策。

Biodiversity and environmental stressors along urban walking routes

There is increasing focus on designing liveable cities that promote walking. However, urban walking routes can expose people to adverse environmental conditions that reduce health, well-being and biodiversity. Our primary objective is to assess how urban form is associated with environmental quality, including biodiversity, for people moving through urban spaces. We assess a range of environmental conditions that influence human health and biodiversity (temperature, noise and particulate pollution) and biodiversity of three taxa (trees, butterflies and birds) along 700 m public walking routes embedded in 500 m x 500 m grid cells across three UK towns. Cells are selected using random stratification across an urbanisation intensity gradient. Walking routes in more built-up areas were noisier and hotter; noise levels further increased in areas with more industrial land-use and large roads. There was no evidence of vegetation mitigating noise or temperature, but there was some evidence that increased vegetation cover mitigated small particulate pollution. Walking routes in more built-up environments had lower butterfly, bird and native tree species richness, and reduced butterfly abundance. Large roads were associated with reduced bird species richness and increased noise was associated with reduced bird abundance. Most specific measures of vegetation in the surrounding matrix (median patch size, structural complexity at 1.5 m resolution) were not detectably associated with biodiversity along walking routes, indicating minimal beneficial spill-over. Increased garden cover in the surrounding matrix was associated with less abundant and less species-rich butterfly communities. Our results highlight considerable heterogeneity in the environmental quality of urban walking routes and pedestrians’ potential to experience biodiversity along these routes, driven by reduced quality in areas with more built cover. A greater focus is needed on mitigating adverse effects of specific features of the built environment (roads, industrial areas, noise) surrounding walking routes to enhance the co-benefits of more biodiversity and healthier conditions for pedestrians.

管氏肿腿蜂的寄生与产卵行为研究

本文研究了管氏肿腿蜂在双条杉天牛幼虫上的产卵行为，其行为过程包括聚集、检验、蛰刺、清理寄主、取食、游走、产卵、休息。在不同寄主上，管氏肿腿蜂卵的分布存在差异：在桑虎天牛幼虫上卵大部分横向排列在寄主体表，两侧和背腹面卵的数量差异极显著；在黄粉虫幼虫体表卵的分布是随机的，卵的排列方向无规律性．从接蜂到产卵，有产卵经验的雌蜂所需的时间显著短于无产卵经验的雌蜂。
