Streams in the Harz National Parks (Germany) — a hydrochemical and hydrobiological evaluation

Between 1995 and 2001, 16 measuring points at small and medium sized brooks in the Harz National Parks were sampled. The samples have been evaluated by means of hydrochemistry and macroinvertebrate biology. Although nearly all streams are largely uncontaminated by oxygen-consuming substances, they are settled only by a small number of macroinvertebrate species. There is a clear correlation between this number and pH. The reduction in species number with decrease of pH is mainly caused by the absence of most Ephemeroptera, some Coleoptera and Trichoptera. Comparing biological evaluation of acidity with physico-chemical measurements, a unacceptable underestimation was found. The reason could be that different sensitivities to acidification between regional populations seem to exist.

Despite of the low species number, there is a very specific macroinvertebrate fauna that emphasizes the conservation value of the Harz National Parks.     

结合农业科技园建设观光农园的探讨——以潮州鹤陇山农业科技园与观光农园的规划设计为例

广东省经济和旅游业发展位于全国榜首，人多地少全国最为突出，但乡村旅游建设相对滞后，文中通过潮州市郊鹤陇山农业科技园与观光农园规划设计，论述了发展高新技术农业是新世纪广东农业必由之路，提出结合农业科技园建设，叠加农业观光园，把生态农业建设与旅游文化结合起来，是广东乡村旅游发展的主要途径。     

梅州市名城文化景观的保护与开发研究

The water level simulation for crane habitat optimization in Xianghai Nature Reserve

The probability of crane living in reedy wetlands can reach 100%, at the same time, the area of reed, the water level and adjacent water area are main factors which control the crane's habitat selection. We all know that all these factors are spatially heterogeneous. For the Xianghai wetland safety and to protect the Xianghai wetland habitat of crane, this paper has mainly identified a solution to these problems. The wetland information is extracted from the TM images, which reflect the whole wetland landscape and are very important for both quantitative analysis of remote sensing observation of the earth system and positioning analysis in GIS database that is automatically extracted from DEM. The DEM for Xianghai characteristics of topography is created. On the basis of the GRID SUBMODULE, applying the GIS spatial overlay analysis, the relationship between the water level and the reed area below the water level and the rating distribution maps of reed area above water level is established. When the water level reaches the altitude of 165 m, the reed area, 981.2 ha is maximum, i.e., the water level of 165 m is the optimal.     

国道219线新-藏公路改建工程地质灾害评价

国道219线新-藏区界至红土达坂路段全长109．55km。大部分路段穿越湖盆槽谷中央部位，部分线路沿湖盆边缘台地布设，海拔高度介于5000-5400m之间，地势平坦开阔，多年冻土发育，工程地质条件较差；现有公路路基高度低，几乎没有排水设施。冬季易产生路基冻胀和涎流冰危害，春、夏季因冻土融化，常引起路基沉陷和翻浆，严重危害公路运输安全甚至阻断交通。公路工程修建活动将极大地改变冻土环境，使天然状态下的水分循环发生改变，导致多年冻土退化，上限加深，进一步诱发冻胀、融沉、热融滑塌等冻土灾害，加剧风沙灾害、诱发公路边坡失稳破坏。在即将进行的公路改、扩建工程中，应采取保护冻土的设计原则，优选线路，加强侧向排水，合理设置取弃土场。

The neoliberalization of ecosystem services: wetland mitigation banking and problems in environmental governance

Wetland mitigation banking is an American neoliberal environmental policy that has created a functioning market in `ecosystem services', commodities defined using the holistic measures of ecological science. The development of this market is discussed as a project of environmental governance, defined as the nation-state's regulation of ecological relations within its territory towards stabilizing capitalist relations of power and accumulation. I argue that the wetland banking industry serves as a bellwether that presages problems that other strategies of neoliberal environmental governance will experience. Ethnographic, economic and ecological data from the Chicago-area wetland banking industry inform a discussion of two major obstacles to neoliberal strategy: the problem of relying on ecological science to define the unit of trade, and the problem of aligning the somewhat independent relations of law, politics, markets and ecosystems across an array of spatial scales. Theoretical guidance is sought from recent work on `social natures' and from the Regulationist approach to institutional political economics.     

试论全球化背景下的非传统安全

非传统安全是近几年频频出现的热点问题。它是在全球化背景下显现的,尤以2001年的“9·11”事件和2003年的非典型肺炎(SARS)为其典型代表。非传统安全越来越受到各国政府和学者们的重视,但它却系不同于过去我们所认识的传统安全,在形成机理、内涵、特点及与其他安全观之间的关系至今还没有得到共识,处于理论的不成熟阶段。因此,文章就以上几点进行了初步的论述。
