There are different understandings of the term evergreen broad-leaved forest (EBLF). In the broad sense it refers to the type of forest vegetation consisting of evergreen broad-leaved trees distributed in areas other than the tropical zone. Taiwan and the

The study of the relationship of plants with their environment is very important for understanding biodiversity patterns. On the northern slope of Changbai Mountain there is not only a high diversity in vegetation types and species, but also high variatio

On the basis of the theory of modularity, the correlation between environmental factors and the modular structure of the Reaumuria soongorica population in the desert of Fukang, Xinjiang, was studied through analysis of the degree of relatedness adopted i

Fog throughfall and related microclimatic factors were measured between November 1998 and February 2003 at a tropical seasonal rain forest in Xishuangbanna, Southwest China. Twelve bottle-funnel collectors were set in a random pattern on the forest floor

Vast areas of secondary tropical forest occur in Xishuangbanna owing to slash and burn cultivation and the destruction of tropical forest, which is a huge carbon and nutrient element bank. In order to know the dynamics of growth and bio-productivity of se

With increased study of global change, the function of vegetation has become more widely appreciated. As one of the characters of the vegetation, the net primary productivity (NPP) becomes an important approach to study the structure and function of the v

Fraxinus mandshurica, native to northeastern China, is an important timber tree. The tree often suffers from nitrogen (N) deficiency because long winter results in slow decomposition rate of litter. In the present study, effects of different concentration

Terrestrial transects have become an important and effective method for the study of global change. The Northeast China Transect (NECT) is one of the fifteen global transects recognized by IGBP, which is assigned along the latitude 43°30′ N in the mid-l

In a temperate marsh in Qinghai-Tibet plateau, the potential CH4 oxidation and production were investigated by field sampling and lab incubation experiments. The potential CH4 oxidation and production rates were measured for four horizons (0-5, 5-15, 15-3

Temperate and tropical oxic soils usually exhibit low levels of atmospheric CH4 oxidation, which are estimated to consume about 10% of the atmospheric CH4. It has been reported that the semi-arid grasslands represent a significant global sink for CH4 and

In order to understand the changes of palaeoclimate and palaeovegetation in Hunshandak sandy land, pollen-spores have been studied from the Gaoximage section (42°57′14.2″ N, 115°22′3″ E, Alt 1 253 m) in the Hunshandak sandy land, Inner Mongolia, Chi

This study explored the quantitative relationship between pollen in the surface soil and vegetation in the Yanshan area. Data were collected from the region between about 39°00′-40°50′ N and between 117°10′-119°50′ E from 2 082 m elevation in the

In this paper, the authors used cluster analysis to study the lichen community structure in the forest ecosystem of the Western Tianshan Mountains of Xinjiang according to the spot survey results for years. The results showed that in this area the lichen

The interactions between vegetation and climate are always an important domain in ecological research. NDVI(Normalized difference vegetation index)is an important index that reflects the radiation-absorbing characteristic of vegetation and the climatic st

Human activities have broken down the barriers to long-distance dispersal of plants. Many plants have been transported by man into areas beyond their natural distribution. Mikania micrantha, a fast growing, perennial, creeping and twining plant, originati

There are many elm (Ulmus pumila) distributed on the fixed sand dune in Hunshandak Sandland. Elms-motte-veldt is the climax community of vegetation succession in this region. Recently, the quantity of elms decreased sharply, especially for the young elms

The old issue of biodiversity-ecosystem function (BEF) has been rekindled in the 1990s due to the fact that the loss of biodiversity caused by the increased human impact on ecosystems may substantially alter ecological functions and jeopardize ecosystem s

It is well known that the global atmospheric CO2 concentration, presently about 360 ppm, is increasing and is expected to double by the end of the next century. An increase in the atmospheric CO2 concentration should increase the plant photosynthetic rate

Canopy dynamics are important in understanding the mechanisms regulating forest production and transition, and maintenance of forest biodiversity. The canopy is the place where important physiological processes such as photosynthesis, respiration, and tra
