国外室内植物的起源和历史

追溯了国外室内植物的起源，盆栽是一个历史性的转折。温室的出现为植物进入室内提供了条件，为室内植物创造适宜的生长环境，其中培育暖房和橙屋都是早期温室的一种形式。阐述了它的历史，在室内植物的产生过程中，植物收集者们的功劳是最大的，19世纪后半期是引进全世界各地室内植物到欧洲的鼎盛时期，植物收集者的贡献不可忽视。在所有收集者们中最有名的两个姓氏是Joseph和Veitch。室内植物令人惊奇的是，各种不同气候带的植物都可以在同一个环境中生长，使得室内的植物物种极为丰富。随着室内环境的改善，可以在室内生长的植物种类将会更多。

The search for fragmentation thresholds in a Southern Sydney Suburb

Fragmentation of habitat is recognised as the number one threat to biodiversity and as such has attracted considerable research. However, much of this research has been conducted in forestry and agricultural environments, with little research in urban areas. In this study, field surveys were conducted measuring the impact of fragmentation on bird, frog, plant and fungi species richness, within the fragmented urban landscape of southern Sydney. Of all fragmentation parameters examined, remnant area was the best and most significant predictor of species richness for all taxa studied. Remnant size thresholds, below which biodiversity declined rapidly, were observed at approximately 4 ha for bird and frog species richness and approximately 2 ha for plant and fungal species richness. A further threshold appears to exist at approximately 50 ha for the dominance of forest interior species. Further relationships were also observed for perimeter:area ratio, indicating the influence of various edge effects on all taxa. Isolation effects were observed in the form of an inverse linear relationship between distance to other large reserves and species richness for fungi, birds and frogs. Corridor connectivity also produced an overall positive relationship for birds, frogs and plants. It is concluded that the identification of fragmentation thresholds and relationships provides an important management tool for the design of networks aimed at conserving biodiversity in fragmented urban environments.

北京野生兰科植物的识别与新分布

<正> 在《北京植物志》下册(贺士元等,北京出版社,1987)中,收录了北京地区兰科植物共计19属、27种,其中野生兰科植物15属、18种。这集中反映了1984年以前北京兰科植物区系的研究成果。近年来,作者在北京百花山自然保护区采集到4种《北京植物志》未记载的兰科植物,其中2个属为北京植物区系属的新记录。至此,北京地区野生兰科植物已达17属、22种。为满足教学和科研工作的需要,特编制北京野生兰科植物检索表,以此介绍了北京野生兰科植物的识别方法,同时对北京地区4种兰科植物新分布予以报道。

Characteristics of Nutrient Contents and Evaluation of Nutritional Value of the Alpine Grassland Plants in the Source Area of the Yellow River北大核心CSCD

In order to explore the characteristics of nutrient contents and scientifically evaluate the nutritional value of the alpine grassland plants in the source area of the Yellow River, the plants of the five different alpine grasslands were selected as the research objects, and the content of crude protein (CP), ether extract (EE), crude fiber (CF), crude ash (CA), total phosphorus (TP) of the plants were determined. At the same time, the principal component analysis method was used for quantitative comprehensive evaluation of the plants nutritional value. The results showed that the CP content of the plants in all alpine grasslands was between 12.78%~15.35%, the EE content was between 2.63%~3.38%, the CF content was between 17.56%~25.16%, the CA content was between 5.52%~11.53% and the TP content was between 0.11%~0.27%. The order of nutrient value of plants in different alpine grassland from high to low was: degraded alpine meadow > native alpine meadow > swamp meadow > degraded alpine steppe> native alpine steppe;The order of yield per unit area of the total nutrients of plants in different alpine grasslands from high to low was: swamp meadow > native alpine meadow > native alpine steppe> degraded alpine steppe> degraded alpine meadow;The order of nutrient value of different plant species from high to low was: Leguminosae>Forbs >Cyperaceae>Gramineae. © 2019 Authors.
