Landscape Structure and Historical Processes Along Diked European Valleys: A Case Study of the Arc/Isère Confluence (Savoie, France)

/ The valleys of European piedmonts constitute changing narrow corridors within which water, matter, nutrients, energy, and species flow. The dispersion patterns of these flows have been significantly disturbed since the end of the 18th century. Thus, western European valleys have been changed into complex mosaics by implementation of socioeconomical programs. In order to define future actions allowing the preservation of this "ecocomplex" (Blandin and Lamotte 1988), it is necessary to gather precise information of the landscape dynamics. Hence, the study of the European river valleys must be based upon two major steps: (1)the analysis of the present landscape with suitable remote sensing techniques, allowing us to map the complex mosaic of narrow corridors; and (2) the analysis of temporal landscape development patterns since the first engineering works that have transformed the braided channel system. In this paper, the efficiency of the addition of two techniques is highlighted: (1) the "wavelet merging method" from multispectral and panchromatic SPOT images for the floodplain land-cover mapping, and (2) the historical reconstruction techniques from old maps and archive documents in order to analyze the cumulative impacts of engineering works on landscape diversity. To illustrate the method, a particularly complex case study is chosen: the Arc/Isere confluence (downstream from Albertville, Savoie, France). Remote sensing, field survey, and historical reconstruction allowed us to distinguish two types of spatial units: (1) the "functional sets" characterized by independent state factors (edaphic, hydrological, and topographic) and supporting a limited number of vegetation types (spontaneous or cultivated), and (2) the functional unit (= ecotope), which corresponds to a unique combination of vegetation type/functional set.KEY WORDS: Landscape ecology; Floodplains; Vegetation; Land use; Remote sensing; Historical reconstruction; Mapping; Merging methods; Human impacts; Alps; Isere river; France     

Counter-disaster training in developing countries

This paper discusses both the need for training within a wider context of community disaster preparedness and the major alternatives in methods of training. Emphasis is placed on the importance of compatibility between the resources within a given country and appropriate training programmes.

行政事业组织建立环境管理体系探讨

目前，我国建立ISO14001环境管理体系的组织主要是企业，然而行政事业组织亦具有建立体系的必要性和可行性，并具有重要意义。行政事业组织在建立体系时，环境因素识别和控制的重点在于资源和能源的消耗及危险废物的处理和处置。体系的建立应与组织的行政管理职能紧密结合，促进环境管理程序化、规范化和法制化，从而实现“绿色行政”的目标。

秦皇岛市水环境现状与恢复

秦皇岛地区原始自然环境优越,多年来,不正当的人为活动、环境恶化趋势明显,也直接干扰与影响着水的良性循环。现状水环境:河流基流渐小,并季节性断流,坑塘减少,湿地萎缩水土流失,洪径增大。地下水位下降,水量减少,承压水无序开采,污净比失衡,河流承栽力降低。地下水垂直污染面扩大,点、面、垃圾污染源趋重。联通青一洋、石一起,实施水资源再分配。优化配置城乡用水。重视地下水源地建设,联合调度地表、地下水源。谨慎开发承压水。植树造林、涵养水分。注重防风林带建设,改善田间小气候。严控地下水采量,防止土壤旱化。搞好坑塘建设,解决乡镇污水出路与净化。保护湿地,促进水的良性循环。深度处理废污水.使之资源化。从源头抓好城市三大水源地污染源.察勘储备新地下水源地。改良恢复水环境,保障水资源循环利用。     

关于秦皇岛市竞争力的初步分析及对策研究

我国城市竞争力研究成果表明秦皇岛市综合竞争力在全国排序第39位,基础设施、环境、区位等硬竞争力较强,而企业管理、制度、文化等软竞争力较弱,因此虽然在河北省名列前茅,但在沿海城市中比较落后,为了增强城市竞争力,必须正确定位、协调发展;发挥优势、加快发展;加快招商引资;进一步开放;加快科技进步,加强精神文明建设;强化城市营销和品牌建设;强化城市和企业管理。
