Some visual aspects of planting design and silviculture across contemporary forest management paradigms – Perspectives for urban afforestation

There is a pan-European interest in increasing the amount of woodland cover, particularly in areas close to urban populations. However, in the enthusiasm for planting trees, is enough forethought given to visual aspects of woodland stand interiors? This paper conceptualises and assesses visual aspects of planting designs and silvicultural principles across three contemporary forest management paradigms: the commercial, the nature-based, and the urban paradigm. Planting design models and silvicultural treatments were conceptualised from a review combined with case studies. Using profile diagrams, we made visual representations of planting design and stand development, as basis for ‘expert’ assessment of four visual criteria: scale, diversity, naturalness and visual accessibility. The assessment was done for the young stage (0–25 years) and the mature stage (50–90 years) separately, using a qualitative three-step scale: limited, medium, and extended. Seven different planting design models were identified. Three of these originate from the urban paradigm: the seed source model, the density gradient model, and the habitat model. Another three originate from the nature-based paradigm: the natural succession model, the nature-based shortcut model, and the direct approach model. Only one model originates from the commercial paradigm: the monoculture model. The assessment showed that visual aspects vary considerably between planting designs and silvicultural systems. The monoculture model offers the splendour of the mature pillar hall with free views and movements, however, necessitating an obvious plantation stage in its youth. In contrast, models utilising succession and variation in species, age and tree spacing offers an extended experience of diversity and naturalness – even in the young stages. These visual qualities are discussed in relation to future perspectives for urban afforestation across urban woodland zones.

基于鱼刺图法的玻璃钢渔船建造质量分析

玻璃钢渔船建造质量的优劣影响其生产使用及其行业发展。为探索影响玻璃钢渔船建造质量的因素,根据已建造玻璃钢渔船存在的质量问题,确定影响其建造质量的关键因素。运用鱼刺图分析法进行分析,以影响玻璃钢渔船建造质量的因素为中心目标,分别从结构设计、原材料选择与处理、以及建造工艺完善3个方面进行归纳分析,将设计因素、原材料因素、工艺因素作为鱼头,其他细分因素作为鱼骨,寻找各影响因素之间的关系,绘制复合式鱼刺图;将鱼刺图作为基础模型,对其中的影响因素进行整合、筛选、甄别,建立便于建造现场管理和控制的系统模型。对造成玻璃钢渔船建造质量差的原因进行分析讨论并提出相关建议。     

具有不稳定零极点对消的结构图等效问题

为进一步完善经典控制论中的结构图简化规则，深入研究具有不稳定零极点对消的结构图等效问题。指出复杂结构图等效后，如果其等效式与其他环节存在不稳定零极点对消，则对消后系统的性质将发生改变，此时应保持原结构图而不做进一步的简化，仿真示例验证这一结论。
