高科技生活用品

助听器眼镜 荷兰科学家最近发明了一种可以同时充当助听器的新型眼镜.这种最近在荷兰推出的新型眼镜式助听器与其他传统助听器有着天壤之别.在每只眼镜腿上都有一排(4个)微型麦克风.这些麦克风会从配戴者的前方采集声音,同时抑制周围的噪音.经过放大的声音最后由两根几乎看不见的传送管输送到人的耳部.这样,配戴者只要面朝相关的方向就能听到想要听的声音.曾经参与了这种眼镜式助听器早期试验的荷兰专家马丁表示:"即使在诸如咖啡馆或聚会等一些声音非常嘈杂的环境中,它也能让人们在自己所看的那个方向听得清楚".这种新型眼镜的价格为每副1700英镑左右,同时还有不同的颜色和样式可供选择.听力有困难的人们还可以按照自身的需要选择平光镜片或是带有度数的镜片.这样,一款眼镜就能同时解决视力和听力两个问题,真可谓一举两得.

The potential of hinoki (Chamaecyparis obtusa [Sieb. et Zucc.] Endlicher) plantation forests for the restoration of the original plant community in Japan

We estimated the potential of plantation forests for the restoration of the original plant community. We compared the understory vegetation in hinoki (Chamaecyparis obtusa [Sieb. et Zucc.] Endlicher) plantations at the understory re-initiation stage and in adjacent natural forests. To estimate the effect of the original natural forests on the understory species composition of plantation forests, we established study sites in five types of natural forests (mature evergreen broadleaf, mature deciduous broadleaf, mature evergreen coniferous, immature deciduous broadleaf warm-temperate, and immature deciduous broadleaf cool-temperate) and nearby plantation forests. The understory vegetation of the plantation forests had a higher species richness, a higher proportion of early-seral species, and a higher proportion of herb or fern species than the natural forests. The differences between natural and plantation forests varied according to the species composition of the natural forests. The composition of the understory vegetation of the plantations at the understory re-initiation stage was similar to that of the immature deciduous forests. The characteristics of immature, disturbed forests remained in the understory vegetation of the hinoki forests. No great loss of species was observed. Our findings suggest that most of the original forest species still survive in the understory of the plantation forests. These forests have the potential to follow the successional pathway to broadleaf or mixed forests via thinning or clear-cutting without planting.     

毛竹油桐混交林生物量和其生态效益的初步研究

毛竹油桐混交林总生物量比油桐纯林和毛竹纯林分别提高了58.37%和13.11%;混交林内立木平均胸径较明显大于纯林;混交林气温温差较毛竹纯林小,而湿度均较毛竹纯林大,表明混交结构使林内气温稳定,湿度增高,有利于林分生长;混交林对林地土壤养分状况有明显改善,其中有机质含量的增幅最大。

宁化县木荷混交造林效果分析

对木荷与杉木、马尾松不同混交方式、混交比例的混交林、木荷纯林的生长效果进行调查分析,结果表明：木荷更适宜种植混交林,杉木×木荷3∶1比例混交林的木荷平均胸径、平均树高、单株材积及林分生长量均比杉木×木荷2∶1混交林及木荷纯林更好,具有显著性差异。混交方式以水平带状混交林分生长更好,水平带状混交木荷的平均胸径、平均树高、单株材积、平均冠幅均比垂直带状混交及木荷纯林高。杉木与木荷混交应控制好木荷的混交比例,否则会影响混交效果,而且到一定年龄时对林分应进行间伐,控制好林分密度,促进林分生长。

DECIDUOUS AND DECIDUOUS-EVERGREEN FORESTS IN NORTHEAST CHINA

Two types of forests in Northeast China is divided in this paper,that is,the decidu-ous forests in the northern part and the deciduous-evergreen forests in the eastern part.Both distri-butions of the two types of forests have also been pre sented.Meanwhile,the development and suc-cession as well as components of forests have been studied in detail.in the end,the vertical distribu-tion of the deciduous forests have been shown,in which,the near-temperate cold temperate decidu-ous coniferous forests are distributing in the low elevation area between 450m—600m from the northto the south,the typical siberian cold temperate deciduous coniferous forests are widely distributingfrom 450m—820m in the north to 600m—1050m in the south, the humid cold temperate deciduousconiferous forests can only be found in high elevation area from 820m—1100m in the north to1050m—1380m in the south,the cold temperate deciduous coniferous open forests can seldom ap-pear at the top of a few peaks.

National assessment of the fragmentation, accessibility and anthropogenic pressure on the forests in Mexico

Forest managers and policy makers increasingly demand to have access to estimates of forest fragmentation,human accessibility to forest areas and levels of anthropogenic pressure on the remaining forests to integrate them into monitoring systems,management and conservation plans.Forest fragmentation is defined as the breaking up of a forest unit,where the number of patches and the amount of expose edge increase while the amount of core area decreases.Forest fragmentation studies in Mexico have been limited to local or regional levels and have concentrated only on specific forest types.This paper presents an assessment of the fragmentation of all forest types at the national level,their effective proximity to anthropogenic influences,and the development of an indicator of anthropogenic pressure on the forests areas.Broadleaf forests,tropical evergreen forests and tropical dry deciduous forests show the greatest fragmentation.Almost half(47%) of the tropical forests are in close effective proximity to anthropogenic influences and only 12% of their area can be considered isolated from anthropogenic influences.The values for the temperate forests are 23% and 29% respectively.Anthropogenic pressure in the immediate vicinity of anthropogenic activities is much higher in the tropical forests(75 in a scale 0-100) than in the temperate forests(30).When considering these results jointly,the tropical forests,and more specifically,the tropical evergreen forests and tropical dry deciduous forests are under the greatest pressure and risks of degradation.     

Myrmecofaunal change with bamboo invasion into broadleaf forests

Recently, it is documented that bamboo (Mousouchiku:Phyllostachys pubescens Mazel) invasion deteriorates ecological and/or landscape diversity. In order to investigate the ecological effects on forest-floor arthropods caused by bamboo invasion, we compared the myrmecofauna among broadleaf forests, bamboo-broadleaf mixed forests, and bamboo forests in Hiroshima City and its vicinity. Myrmecofauna in bamboo forests were more impoverished than in broadleaf forests. Myrmecofauna in the mixed forests, however, were similar to that in broadleaf forests in both species diversity and species composition. The change in myrmecofauna may occur relatively late after the initial bamboo invasion.
