Avifauna become a part of study in the modern ornithology.

对于鸟类分布的研究,被作为现代鸟类学中一个重要研究内容。

Biotope types had impacts on birds distribution,and several bird biotope-groups were observed.

In this study, the researches are focused on slighting topics, such as the bird biodiversity and heterogeneity of bird community, improvement of statistic methods and blending landscape ecology with avian ecology on scale and heterogeneity.

l、突破现行鸟类群落研究思路,本文结合与鸟类分布密切相关的生境因子,将鸟类分为不同的类型后再进行生态学分析,以避免冗余种对多样性和聚类的影响,正确显示物种在生态系统中的不同地位和作用。

Landscape difference are not relative with biota index in this research. There are negative between MPFD index and bird index in class level, it meas the mor complex of the land patch shape the lower dird index. And last in LSIM index are negative relative with bird index.

在土地利用层级的地景歧异度分析与生物的歧异度分析结果在本研究中没有相关,在土地利用类别层级的指数计算方面,碎型维度与鸟类歧异度呈现负相关,表示土地使用形状越复杂,鸟类歧异度越小;而最大地景比例的部份,则与鸟类歧异度成负相关。

Fruits eaten by birds are mostly fleshy types such as berries, drupes, pomes and cones, or with their seeds enclosed by fleshy arils, and when ripe, the colors of these fleshy pericarps or arils usually turn conspicuously red, black, and yellow, which are very attractive to frugivorous birds.

适于鸟类取食的植物果实大多数为浆果、核果、梨果及球果等肉质果实,或者种子为肉质的外种皮或假种皮所包被;并且这些肉质的果皮、外种皮及假种皮在果实及种子成熟时通常具有鲜艳的红色、黑色及黄色等颜色,容易被鸟类发现,并吸引鸟类前来取食。

Identification of bird feather by microscopical technology is to use light microscope or electronic microscope to observe and examine the appropriately treated feather so as to obtain the differences of micro-structures between different species of birds. These micro-structures, associated with taxology of birds, can be used to distinguish, identify and recognise different species of birds.

中文摘要:鸟羽显微鉴定即使用光学显微镜和电子显微镜对经适当处理的鸟羽材料的细微结构进行观察,发现不同物种鸟类羽毛的显微结构差异,主要根据显微镜观察到的鸟羽上独特的结构差异,结合宏观的鸟类分类系统知识,从而达到鸟类物种区分、鉴定、识别的效果。

Animal community structure and diversity showed the marked seasonal changes., The maximum of Arthropods individual number, species number and species diversity were in late July - early August. The groups number of soil animals was the maximum in summer, and the individual number was the maximum in autumn. The species number of birds; was the maximum in spring, the main species of bird community were migratory birds in spring and summer, and the main species of bird community were resident birds in autumn and winter.

节肢动物群落在7月下旬-8月初具有最高的物种数、个体数和多样性指数;土壤动物群落在夏季具有最高的类群数,秋季具有最高的个体数量和多样性指数;鸟类群落在春季具有最高的鸟种组成,春夏季节鸟类群落的主体是候鸟,秋冬季节鸟类群落的主体是留鸟。
