关于林业数学模型中参数的取值问题

针对国内林业期刊文献中普遍存在的数学模型参数取值不规范的问题,提出林业数学模型的参数取值,应遵循小数位统一和有效数统一的原则,而且有效数统一原则应该成为最高准则;同时还对与这两项原则有关的某些特定林业数表模型中参数的取值和估计问题进行讨论。     

几种农林废弃物发酵基质与常用轻型基质的理化性质比较

收集山核桃壳、锯末、枯枝落叶、菇渣、中药渣5种常见农林废弃材料,经过发酵和消毒处理,按照不同配比混合成8组不同的轻型栽培基质,测定其理化性质,并与日常栽培容器苗的轻型基质泥炭和珍珠岩比较。结果表明:8组不同轻型基质的容重、总孔隙度、通气孔隙、pH值、全N差异显著;持水孔隙、大小空隙比、EC值、全P、全K(除6、7号基质外)、速效K差异极显著(1%水平);以2号混合基质锯末:枯枝落叶:山核桃壳:珍珠岩=4:2:3:1(体积比)为最佳配比。     

中国多功能林业思想的历史演进

充分开发利用林业的多种功能已成为中国林业的一项紧迫任务, 研究和借鉴历史上已有的多功能林业思想有着重要意义。文中从历史角度对多功能林业思想进行了初步总结。结果表明, 从先秦时期开始, 人们就已经认识到森林具有多种功能, 但直到明代尚没有形成系统的论述; 清代俞森是比较早地系统论述林业具有多种效益的学者; 1947年, 郝景盛发表《森林万能论》, 标志着中国多功能林业理论正式诞生; 20世纪末出现的现代林业理论, 在突出强调森林生态效益的同时, 要求高效发挥森林的多重功能和价值; 2010年, 《中国多功能林业发展道路》著作出版, 使该理论进一步完善。

Higher Education on Urban Forestry in Europe: An Overview

In order to meet the demands of modern, information-based society, higher education in natural resource management needs to be transformed. Enhanced mobility of students and staff, multi- and transdisciplinary approaches, as well as innovative educational approaches are called for. Moreover, the urban component needs to be better incorporated, as exemplified by the emerging field of urban forestry. This paper relates to the developments in higher education within the context of education on urban forests and urban trees in Europe. Presented here are the main findings of a comparative European study led by the Danish Forest and Landscape Research Institute within the framework of the EU-funded COST Action E12 'Urban Forests and Trees'. In order to obtain an overview of the status of higher education on urban forestry in Europe, 180 educational institutions in 28 countries were sent a questionnaire. Results show that urban forestry is an expanding element of European education, as urban elements are becom
