油茶织蛾生物学特性研究

Casmara patrona is one of the main borer pests damaging Camellia oleifera in China. Few reports about this insect were published. The life history, biological characteristics and natural enemies of C. patrona were investigated through field survey and laboratory observation in this study. The results showed that C. patrona had one generation in one year or two years, and overwintered as 3rd-5th instar larva in Zhejiang Province. About 88 percent of larvae began to pupate in early May, and the rest kept feeding till the next year. The adults could be observed from early June to early July, and the peak of emergence occurred in late June. The adults began to oviposit in late June and terminated in early July. The eggs started hatching in early July, and then the larvae bored into the branch to feed. The entrance holes of the larvae distributed predominately in the middle of the eastern and southern part of C. oleifera tree. The larva had five instars, and there were 10-50 days when the larva did not feed between consecutive instars.     

基于翻转课堂模式的园林史教学改革探索

FC模式即"翻转课堂",也称为"颠倒课堂",是利用信息技术"翻转"知识传授和知识内化2个学习过程的全新教学模式。园林史是风景园林专业的重要专业基础课程,笔者经过历年园林史课程教学实践经验的积累,结合地区实际,探索了基于翻转课堂理念的园林史教学模式改革的实施途经,以期合理地解决好传统园林史教学革新中的相关问题。通过改进多媒体教学方式,高效利用课堂时间,充分发挥学生的学习主动性,进而提高教学效果和学生的学习兴趣,为园林史教学改革提供参考。     

One hundred years of population ecology: Successes,failures and the road ahead

Population ecology is the most mature of the three subdisciplines of ecology partly because it has a solid mathematical foundation and partly because it can address the primary questions of distribution and abundance with experimental protocols. Yet there is much left to do to integrate our population knowledge into community and ecosystem ecology to help address the global issues of food security and the conservation of biodiversity. Many different approaches are now being developed to bring about this integration and much more research will be necessary to decide which if any will be most useful in achieving our goals of explaining the changes we see in the distribution and abundance of animals and plants. Food web ecology would appear to be the best approach at present because it uses the detailed information of the population ecology of particular species in combination with data on consumer–resource interactions to apply to the applied problems of biodiversity conservation, food security, pest management and disease prevention. If we can use our understanding of population ecology to address the practical problems of our time in a creative way, we will benefit both the human population and the Earth's biodiversity. Much remains to be done.     

抗战时期沦陷区文化的特点--奴化思想教育

抗战时期,日本帝国主义为了使文化为侵华战争服务,在沦陷区实施的奴化思想教育,是一种具有欺骗性、侵略性、组织性和高度的垄断性等特点的文化现象.奴化思想教育不仅在精神上摧残中国人民的民族意识,而且在物质上对我国教育硬件设施进行损坏.其实质是日本"兴亚院"文化部进行的一场"教育一体化"的政治阴谋,是一种思想渗透和文化侵略,这种侵略比其政治、经济、军事上的侵略更为疯狂、残暴.

鸡蛋花植物文化和国内栽培历史

鸡蛋花原产美洲热带地区,现已广泛种植于热带亚热带地区。除园林观赏外,其花可食用、药用,且寓意丰富。据考证,鸡蛋花在我国已有300多年的栽培历史。本文从自然分布、相关文化以及引入中国时间考证三个方面对鸡蛋花作系统而全面的介绍。     

山东省竹子发展史研究

目前山东仍是一个少林省份,大力发展竹资源和竹产业,对促进山东省生态文明建设和乡村振兴意义重大。研究表明,山东有5 000多年竹子栽培利用的历史,竹文化积淀深厚。新中国成立以来,通过开展南竹北移工作,竹子科研和生产都取得很大成效。在气候变暖、绿色转型发展的新时代背景下,因地制宜、依靠科技和政策,大力发展竹子栽培、广泛开发竹子多重价值,实现生态、经济、文化融合发展,具有十分广阔的前景,必将再造齐鲁竹文化兴盛和竹林美丽风景线。     

基于“三生”空间视角的中国农业文化遗产研究文献分析与评述

本研究基于“生产、生活、生态”的空间理论视角,揭示中国农业文化遗产“三生”空间人地关系的研究现状。以“农业文化遗产”为关键词,采用Citespace5.5文献计量分析工具和归纳方法,梳理了近年来中国农业文化遗产的研究成果,结果表明:2005—2020年中国农业文化遗产的研究经历了初步探索、波动增长、平稳发展三个阶段,各个阶段上的研究热点具有明显差异。目前中国农业文化遗产在景观价值挖掘、旅游开发、乡村振兴等领域的研究成果已初具规模,但在基础性理论方面尚未形成权威的认知。农业文化遗产在“三生”空间上的研究对于解决“三农”问题具有重要的实践意义,今后应更加关注基础理论的更新、强化实证研究、贯彻“分层”保护思维、完善社区参与、加快农业文化遗产地的评价指标体系构建和动态保护,以期实现农业文化遗产的高效利用及可持续发展。     

紫菜的生殖与生活史研究进展

紫菜（Porphyra sp．）是目前世界上人工养殖海藻中经济价值较高的种类。紫菜通过不同的生殖方式来完成生活史，从而达到繁衍后代的目的。紫菜的生殖主要有无性生殖和有性生殖，单性生殖是一种特殊的有性生殖。紫菜生殖方式的多样性决定了生活史的多样性，这是进化过程中对不同环境做出的不同反应。紫菜的生殖和生活史受基因控制属遗传基础研究，它对紫菜的育种应用起着重要的指导作用。本文对紫菜生殖和生活史的研究状况以及研究中存在的问题进行评述，旨为紫菜的育种的研究和应用提供理论参考。
