  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.

Wetland biodiversity means mainly the types of wetland ecosystem and biological species diversity.Biodiversity includes all species of plants,animals and microbes,all gene possessed by them and all ecosystems consisting of them and environment.According to the origin and genesis,China's wetlands can be divided into natural wetland ecosystems including mires,lakeshores,bottomland,seashore,wet meadow,etc.,and artificial wetland ecosystem including paddy field.Then based on geomorphological...

Wetland biodiversity means mainly the types of wetland ecosystem and biological species diversity.Biodiversity includes all species of plants,animals and microbes,all gene possessed by them and all ecosystems consisting of them and environment.According to the origin and genesis,China's wetlands can be divided into natural wetland ecosystems including mires,lakeshores,bottomland,seashore,wet meadow,etc.,and artificial wetland ecosystem including paddy field.Then based on geomorphological type,these ecosystems can be divided into 15 subsystems,then based on soil substrata and ecological niche conditions,they can be subdivided into 15 classes,finally according to construction species of plants,several types can be divided into.They are not only the expression of ecosystem diversity,but also the base for biological communities subsistence.This peculiar ecological niche provides a complex and perfect special habitat for various animal and plant communities.In this special habitat,there exist various biological types from monomolecular microbes to higher plants and animals, especially some endangered and rare plants and animals.According to the statistics,there are more than 300 species of birds in China's wetlands,making up one-third of the total number of China's birds.Wetlands not only the goodplace for waterbirds living, but also the important environment on which wild animals and plant rely for existence. There are 65 species of mammals,50 species of reptiles,45 species of amphibious animals, 1040 species of fish, 825 species of higher plants, 639 species of angiosperm,10 species of gymnosperm, 12 species of pteridophyte and 164 species of bryophyte investigated in China's wetlands.

The interaction between human activity and landscape structure of the five scenery plots in the studied region was analyzed, with the ratio of unused land as human activity index.The study showed that human activity had influences on the landscape pattern and structure.With the intensification of human activity, the landscape fragmentation and complexity decreased and the landscape isolation of those man made landscape types, such as residential sites and farmland,increased ,while those natural or remained...

The interaction between human activity and landscape structure of the five scenery plots in the studied region was analyzed, with the ratio of unused land as human activity index.The study showed that human activity had influences on the landscape pattern and structure.With the intensification of human activity, the landscape fragmentation and complexity decreased and the landscape isolation of those man made landscape types, such as residential sites and farmland,increased ,while those natural or remained types, such as unclaimed land and forest land,decreased.The structure index can be used to describe the spatial distribution of human activity. The landscape diversity of the scenery region is higher than that of agricultural landscape and wetland landscape but lower than that of more developed region, and the value for tourism of the scenery plots in the region becomes higher when the landscape diversity becomes lower.

以未利用地比为人类活动强度指标 ,对研究区域中的 5个景区的人类活动与景观结构的关系进行了分析 ,结果表明人类活动强度对景观格局和结构指标有一定的影响 ,随着人类活动强度的提高 ,景观格局的复杂程度变小 ,景观破碎度加大 ,人工干预较大的景观类型如居民用地、农田的分离度变小 ,自然或半自然的未利用地和林地的分离度变大。景观结构指标可以用来描述人类活动强度的空间分布。风景区的景观多样性高于一些经济更发达地区 ,低于一些农业与湿地景观。风景区的旅游价值越高的景区 ,景观多样性越低。

Dongting lake wetland constitutes one of the three major wetland resources concentrated in the middle and lower reaches of the Yangtze River. A special eco tourism landscape was formed under long term common interactions of special geographic environment, natural conditions and human activities. There are obvious circular landforms like dish shaped basin belt landforms, typical subtropical monsoon humid climate and extremely rich plant and animal resources that consist of principal factors of the region's eco tourism resources which are distributed in eastern, southern and western parts. The superior geographical location and typical seasonal eco landscape, uniqueness to the Dongting lake wetland eco tourism resources, make it a diversified eco tourism resources covering almost all subtropical interior wetland types. However, man's disturbances such as land reclamation, industrial waste and pesticide pollution, blindness hunting and fishing have resulted in fragility to the wetland ecosystems. Hence countermeasures should be taken to maintain natural ecosystem of the wetlands to a certain spatial extent, to provide solutions to conflicts between farmland and lake area, to minimize lake sedimentation, and to stabilize area of natural landscape of the lake and marshes, to enlarge natural protedted area and to rehabilitate wetland ecosystem. Long term ecological monitoring should be practiced. In a word, the exploitation of wetland eco tourism resources should be protective exploitation, and the tendency of only laying stress on production function and neglecting ecological function must be altered. The comprehensive exploitation of social, economic and ecological effects should be followed to realize sustainable utilization of wetland eco tourism resources.

洞庭湖区湿地是我国长江中下游地区三大湿地资源集中地之一 ,在其特殊的地理环境、自然条件和人类活动的长期共同作用下 ,形成了独特的湿地生态旅游资源景观、明显的碟形盆地带状地貌、典型的亚热带季风湿润气候、极为丰富的动植物资源、构成该区生态旅游资源的主要因素 ,又呈东、南、西三大片分布 ,且各具特色 ;洞庭湖湿地生态旅游资源的特殊性。几乎涵盖亚热带内陆所有湿地类型造就了该区湿地生态旅游资源的多样性。围湖造田人工围垦、工业废水农药污染、乱捕乱猎人类干扰导致了该湿地生态旅游资源系统的脆弱性。治理对策为 :退田还湖 ,确保自然湿地生态系统面积 ,科学解决“田湖之争” ,复还湿地生态系统。标本兼治 ,力争入湖泥沙量控制到最小程度 ,稳定湖泊、沼泽等自然景观面积。恢复重建 ,规范与扩大湿地自然保护区 ,并进行有效的长期监测。总之 ,洞庭湖区湿地旅游的开发 ,必须定位为生态旅游资源的保护性开发 ,改变只重视湿地生产功能而忽视其生态功能的倾向 ,全面开发湿地的社会、经济和生态综合效应 ,实现湿地生态旅游资源的永续利用
