  wetland
Plant species diversity of wetland ecosystem in an arid and semi-arid region in northwest China
      
The whole study area was divided into the wetland zone, the ecotone and the arid grassland zone in terms of habitat characteristics and vegetation types.
      
angustifolia organs in the two types of wetland communities was distinctly different, which could be described by polynomial.
      
To determine the impact of photosynthesis and transpiration on nitrogen removal in wetlands, an artificial wetland planted with reeds was constructed to treat highly concentrated domestic wastewater.
      
Results suggest that the photosynthesis and transpiration of wetland plants have a great impact on nitrogen removal efficiency of wetlands, which can be enhanced by an increase in the photosynthesis and transpiration rate.

To allow increased understanding of the global budget of atmospheric Methane,individual sources and spatial variability of methane emissions require investigation as one ofgreenghouse gases warming the atmosphere. The study on the emission of methane flux innortheast China has proposed for a part of our joint research program,established by Nagaoka College of Technology and Heilongjiang Hydraulic College. We reviewed the globalmethane emissions,complied with a national contribution basis and with a methane sourcebasis,to address the regional characteristics of northeast China as sources of the atmospheric methane. The emission of methane from soils could occupy a large fraction of thewhole emission in northeast China because a large area of wetlands and rice paddy fieldsexisted in this area. Future works of measuring and analyzing the methane emission ratesfrom the soils are outlines in this paper.

为了加深对全球空气中甲烷含量的理解,甲烷散发量的个别源和空间变量做为影响大气的温室气体需要调查研究。将甲烷散发量在中国东北部的研究做为一个合作项目由日本长冈工业高等专门学校和黑龙江水利高等专科学校共同完成。考察全球的甲烷散发量,在考虑各国对此量的影响及一个甲烷散发源的基础上,把中国东北土壤做为大气甲烷的散发源,在中国东北土壤中的甲烷散发量占全区甲烷全部散发量的大部分,因为该处存在大面积的湿地和水田、本文指出需进一步加强土壤甲烷散发量的测定和计算工作。

Landscape change is the process of landscape transformation from one phase to another, as a reault of interactions between the inner contradictions and outer factors. Using technology of remote sensing and GIS, the paper analyzed two maps of wetland types of Liaohe delta in different periods to study the changes of wetland landscape in time and space. We found that the change of the components of the studied area is not very evident, the artificial wetlands, semi natural wetlands and natural wetlands are still the main components of the area which is more than 90% of the total area. The changing tendency of wetlands is from the land to the sea. The semi natural wetlands are diminishing in recent years, and the artificial wetlands and natural wetlands are increasing comparatively. There are two main factors determining the landscape changes, which are the nature evolution itself and the human disturbances.

利用遥感、GIS手段对辽河三角洲1986年和1994年两个时段的湿地景观进行研究,认为本区景观变化是由两种作用力相互作用而形成的,从而形成了本区独具特色的景观变化方式,即半自然湿地(以苇田为主)向人工湿地(以稻田为主)转化,自然湿地(主要是滩涂景观)向半自然及人工湿地转化的特征。表现出一种自陆向海的变化趋势
