为下一代作准备:林后四林平地森林园区规划

林后四林平地森林园区是一处集平地造林、在地文化、栖地营造、资源利用与环境教育为一体的学习园区。在其不断的发展下,现成为大武山低海拔自然森林园区,作为生态栖地修复、区域文化体验及休闲游憩的场域。从环境修复的角度保有农垦地和草生地生态环境,并营造大武山低海拔森林的栖地环境,提供猛禽、鸟类及两栖类动物栖息繁衍之地。重视生态保育意义的同时,发挥环境教育和生态旅游的价值。因气候环境变迁,以分散排水、贮流、自然入渗及自然过滤方式为主,同时进行土壤地利改良,达到环境保全修复的功效。以现地环境保育及生态演变历史延续对自然环境的关怀,营造合宜的生态栖地、掌握水资源的保存与再利用,为下一代的自然生态环境作准备。

梯级水库群鱼类栖息地保护适应性调控理论框架与技术路径

梯级水库群会使河流鱼类栖息地非生物因子时空节律发生一系列改变,进而对其生物因子产生累积效应与叠加影响,鱼类栖息地保护已成全球河流生态保护的国际前沿。在尊重河流自然法则前提下,辨析了当前受梯级水库群调控的河流鱼类栖息地受损问题症结与治理模式路径不足,运用系统思维赋予了梯级水库群新的生态使命,提出了面向河流鱼类栖息地系统保护的梯级水库群适应性调控理论框架,探索了面向鱼类栖息地非生物因子生态型“正向演替”的梯级水库群“精密监测—精确预警—精细布局—精准调控”适应性调控技术路径,对下一步梯级水库群鱼类栖息地保护提出了发展建议,为全球河流生态保护提供了较强现实意义的“科学方案”。

Contribution of City Prosperity to Decisions on Healthy Building Design： A case study of Tehran

In this paper, the city prosperity manifest is analyzed through a logical process and a framework is then proposed for designing healthy buildings in Tehran. The current status of urbanization in terms of the number of people living together and the changes in old behavior and perspectives have resulted in deficiencies to the health and hygiene of buildings apart from their surrounding environment. Consequently, these problems have affected people＇s well-being. This study mainly aims to determine policies and strategies for the architectural design of healthy buildings according to health and safety conditions that influence the quality of internal spaces and external environment of cities. The study is conducted based on logical reasoning and uses focus group and in-depth interviews to assess the final result. The result is a framework that suggests a number of policies that can promote the mental and physical health as well as hygiene of residents through healthy buildings.

现代海洋牧场建设的人工生态系统理论思考

文章在系统总结国内外海洋牧场概念演进过程及其实践发展历程的基础上,提出现代海洋牧场建设存在生态学理论缺失、生态工程技术缺少、生态管理缺位问题。以问题为导向提出海洋牧场人工生态系统概念,并从海洋牧场渔业资源关键功能群构造及其生境营造角度,全面剖析了海洋牧场人工生态系统的结构原理。最后探讨了海洋牧场人工生态系统构筑的基本范式,包括海洋牧场人工生态系统方案规划设计、生态工程与智能工程建设、生态适应性管理模式建立等,以期为我国现代海洋牧场建设探索生态学理论体系。
