Spatial variations in daily average CO2 concentrations above wetland surface of Xianghai National Nature Reserve, China

Horizontal and vertical variations of daily average CO2 concentration above the wetland surface were studied in Xianghai National Nature Reserve of China in August, 2000. The primary purpose was to study spatial distribution characteristics of CO2 concentration on the four levels of height(0.1 m, 0.6 m, 1.2 m and 2 m) and compare the differences of CO2 concentration under different land covers. Results showed that daily average CO2 concentration above wetland surface in Xianghai National Natural Reserve was lower than that above other wetlands in northeast China as well as the worldwide average, suggesting that Xianghai wetland absorbed CO2 in August and acted as“sink” of CO2. The horizontal variations on the four levels of height along the latitude were distinct, and had the changing tendency of“decreasing after increasing” with the increase of height. The areas with obvious variations were consistent on different levels of height,and those with the highest variations appeared above surface of shore, sloping field, Typha wetland and Phragmites wetland; the vertical variations were greatly different, with the higher variations in Phragmites wetland and Typha wetland, and the lands near the shore and the sloping field with the lower variations. Spatial variations of daily average CO2 concentrations above wet!and surface were affected by surface qualities and land covers.     

不同农业灌溉用水对土壤理化性质影响的研究

编者按 土壤管理和土壤利用方式影响着土壤的发育方向和土壤的性质(如土壤质地、土壤环境、土壤生态等).农业生产中对土地的不同管理措施或方式直接影响着农业土壤的发展方向和土壤环境变化.城市污水往往有较高的肥力,利用其灌溉农业,即能利用水源又能利用其中的肥源,有利于农业生产.

鸭儿湖地区多氯代二苯并二恶英／呋喃（PCDD／F）的污染状况及其来源归宿的初

对鸭儿湖地区的底泥和土壤样品中的多氯代二苯并二恶英／呋喃ＰＣＤＤ／Ｆ）的污染状况进行了研究，结果表明，鸭和湖部分地区已被ＰＣＤＤ／Ｆ严重污染，该类污染物来地附近某化工厂排放的化工废水，其中，ＰＣＤＤ／Ｆ主要以高氯取代的ＨＰＣＤＤｓ和ＯＣＤＤ为主，总结我们的已有实验结果，鸭儿湖１号氧化塘中高残留的ＰＣＤＤ／Ｆ如果控制不当将会转移扩散，可能造成对周围环境的进一步污染。     

Ecological networks and greenways in Europe: reasoning and concepts

The paper gives an overview of approaches towards ecological networks throughout Europe.It does not intend to present a complete picture,but to highlight comon developments within countries and regions and show common principles and differences between countries and regions that have to be taken into account when developing a joint European intiative,Countries or regions that have not been included can be active in the same way ,but information was not accessible to be authors for different reasons.This overview shows the comparable trends in decline of landscapes and the diversity in approaches to biodiversity conservation and nature conservation planning.Understanding the differences and common issues are of utmost imprtance to generalise common principles and to understand the way neighbours and other European partners approach problems.     

新疆农用地变化的环境效应

土地生态环境问题一直都是专家、学者研究的热点话题,土地利用的生态环境效应更是人们日益关注的问题,以新疆1996-2004年农用地详查数据为依据,在分析研究土地利用的变化特点的基础上,阐述了农用地变化产生的环境效应.尽管农用地数量在整体上是增加的,但是土地沙化、退化,水土流失、生物多样性减少等一系列生态环境恶化现象仍在继续.因此,新疆农用地要在水资源的承载范围内适度增加.目前,新疆农用地变化给整体环境带来负面的效应,仅使局部生态环境改善,整体环境变坏.因此,新疆在土地利用中,要以此为鉴,加强生态环境建设,注重各种功能用地的结合.
