磊晶用基板

一種磊晶用基板包含一磊晶用的基材、一形成於基材的犧牲膜，及一磊晶形成於犧牲膜的半導體磊晶膜，犧牲膜包括複數膜區及複數由膜區界定的第一通道，每一膜區具有一奈米材料及複數由奈米材料界定的第二通道，濕式蝕刻劑藉由第一、第二通道得以快速地滲入犧牲膜中，進而快速蝕刻犧牲膜並有效地加速了移除基材的速率

海岸带不同类型木麻黄防护林的温度效应场

为了探讨木麻黄海岸防护林的温度效应场,2006年11月在东山岛对木麻黄基干林带、片林和农田防护林用多点多线的方法进行了温度测定。调查结果为:基干林带内外温差2℃左右,空间分布成中间低四周高的槽状;片林内外相差1℃-2℃,空间分布为中间低四周高的盆状;农田防护林内外温差为1℃左右,空间分布为狭长的带状。三种不同的林分等值线在林内都形成一定面积的闭合区域。国家“十一五”科技支撑计划项目(2006BAD03A14-01);; 福建省重大科技专项(2006NZ0001-2

Global Climate Change and Adaptive Management of Forest Ecosystem

人类活动所引起的温室效应及由此造成的全球气候变化对全球生态环境的影响正越来越引起人们的关注。森林作为全球陆地生态系统的一个重要组分,对全球气候变化的响应较为敏感。文中系统总结了全球气候变化对物种和森林类型分布、森林生态系统结构和物种组成、森林生产力、森林土壤碳氮循环和森林灾害等几个方面的影响,以及森林生态系统管理面临的挑战,在此基础上提出了适应未来气候变化的森林生态系统管理策略。Human-induced greenhouse effects and their impacts on global climate change and eco-environments,especially the responses of forests to global climate change,have increasingly aroused the concerns worldwide.The forest,as an important component of global terrestrial ecosystem,is more sensitive to the response of global climate change.This paper systematically summarized the existing impact of global climate change on the distribution of species and forest types,forest ecosystem structure and species composition,forest productivity,forest soil carbon and nitrogen cycle and forest disasters,and concluded the challenges which the forest ecosystem management is facing.Based on the review,the forest ecosystems management strategies adaptable to the future climate change were proposed.国家自然科学基金项目海陆交界带的土地利用变化对典型植被碳吸存影响的宏微观尺度研究(41176092); “十一五”国家科技支撑项目南亚热带防台风防护林体系研究与示范(2009BADB2B0302); 国家林业局南方山地用材林培育重点实验室; 福建省森林培育与林产品加工利用重点实验室资助项

Ecosystem Processes and Sustainable Management of Coastal Protection Forest of Casuarina equisetifolia

木麻黄为我国东南沿海防护林体系的主栽树种,如何维持和提高其环境调控功能成为当前沿海防护林经营的重要科学问题。文中概述了海岸带木麻黄林生态系统的物质循环、能量流动和防护功能以及育林措施对森林生态系统的影响等国内外研究成果,指出木麻黄人工林具有生产力高、光能利用率高和适应性强的特点;在探讨干扰与木麻黄林生态系统退化之间关系的基础上,提出加强木麻黄海岸防护林的恢复重建与生态系统管理等建议。Casuarina equisetifolia is a major species planted in protection forest along the coast of southeast China.At present,how to sustain and enhance its environmental regulation functions has become important science question for local protection forest management.This paper reviewed the research at home and abroad on nutrient cycling,energy flow and protective functions of C.equisetifolia ecosystem in coastal zone as well as on the effects of forest management measures on forest ecosystem,indicating that C.equisetifolia plantations have the characteristics of high production,high photosynthesis rate and better adaptive abilities.The relationship between disturbance and the degraded C.equisetifolia ecosystem was discussed.Then the suggestions were made for the restoration and reconstruction of the damaged C.equisetifolia protection forest and the management of its ecosystem.国家自然科学基金项目(41176092);国家“十一五”科技支撑计划(2009BADB2B0302);国家林业局南方山地用材林培育重点实验室、福建省森林培育与林产品加工利用重点实验室资助项
