淮河流域用水效率研究

为研究淮河流域水资源利用效率,从淮河片水资源公报中提取相关指标数据,以淮河流域水资源二级分区为单元,基于数据包络分析法(DEA)和层次分析法(AHP)模型计算出淮河流域各市的用水效率.结果表明,淮河上游以漯河和平顶山市为优,淮河中游以郑州和徐州为优,淮河下游以扬州和盐城为优,沂沭泗以淄博和商丘为优.

Planning and design of Berg-en-Dal,a new camp in Kruger National Park

The premise of this article is that the planning and design of new rest camps in conservation areas should be based on ecological principles in such a way that the plant ecology within the camp be an integral part and extension of the natural ecology of its immediate vicinity. This is desirable so that visitors to the camp will be provided not only with facilities for resting, eating, and sleeping, but also be able to enjoy and study the natural environment in a relaxed atmosphere. The Berg-en-Dal rest camp, which was established in Kruger National Park, was planned in such a way and designed according to the principles outlined by the authors in a companion article. The planning included six zones: a control zone, day visitor zone, overnight visitor zone, staff accommodation zone, recreation zone, and service zone. The point is stressed that plant species selected to be used as additional vegetation to those already growing in the camp were endemic to the nine landscape facets identified in the camp. The design allowed for separation of the various land-use zones in such a way that they would complement each other rather than be a hindrance to each other. The camp has been built according to the plans included in this article and has proved to be a great success. The conclusion is drawn that the planning principles are sound and should be used in the future for the planning and design of rest camps for conservation areas in South Africa.

The relationship between sustainable development and resource use from a geographic perspective

Geography provides the basic building blocks for the study of resource use and sustainable development, inasmuch as it categorizes the human environment. Within the environment are resources that are needed for the survival of society. As resources are largely limited and finite, humans as agents of change must employ techniques that allow an efficient and lasting use of the available resources in their environment. This paper discusses the nexus between geography, resource exploitation, use, and sustainable development. It also discusses the characteristics, types, and classification of resources, development and sustainable development as well as the challenges and strategies for attaining sustainable development, particularly in developing countries.     

Using Participatory Rural Appraisal to explore coastal fishing in Badagry villages,Nigeria

Fish production and marketing are as old as the rural communities involved in the lucrative occupation in Badagry area of Lagos State, Nigeria. A random sampling of 200 fishermen using Participatory Rural Appraisal techniques (PRA) in five Badagry villages was used to explore coastal fishing and socio-economic development in the study area with a view to enhancing local productivity and sustainability. The findings show that an average fisherman in Badagry is aware of the resources available in his environment, and can affect productivity levels positively if given adequate incentives. There are two lessons from this study; one has to do with what PRA tells us about the fishing community, the other is the importance of facilitators that have, amongst other things, good listening skills. The experience also revealed that field workers’ ability to listen and learn from local fishermen was a critical factor in collecting in-depth information that could be used for rural community planning.     

Distribution of some trace metals and their fluxes in the Genesee River,NY

Total and particulate metal concentrations, measured during intensive synoptic studies of the Genesee River, NY, correlated with suspended-sediment concentration and river discharge. Dissolved metal concentrations, on the other hand, showed little systematic variation over the length of the river. Metal and sediment fluxes for two elevated-discharged periods peaked at a midbasin sampling site. For most metals at most sampling sties particulate materials comprised over one-half of the total material. Comparison of particulate material metal concentrations, normalized to the measured suspended-sediment concentrations had with basinwide average values shows that sites having low suspended-sediment concentrations had high particulate material metal contents relative to the basin averages, while sites with high suspended-sediment concentration had low metal contents. These results are consistent with a metal transport mechanism in the Genesee River involving (1) a nearly constant dissolved component, (2) a fine acid-soluble component, and (3) a coarse component that is effectively a neutral diluent in the sediment. Chemical factors, such as sediment organic content, also appear to affect metal transport in the Genesee River.     

WATER RESOURCES OF MEXICO1

The aim of this paper, based fundamentally on the experiences and data obtained by staff members of the Secretaria de Recursos Hidráulicos, is to present a general view of the water resources of the Mexican territory. Unfortunately, there does not exist a rational and adequate distribution of those resources, due to a great number of factors, mainly natural, which we must control to attain a convenient rationalization to meet the requirements of a growing population and industry.     

水资源对人类安全的负面影响

水是丰富的.但水不等于水资源.由于水资源分布不均、人类需求的不断膨胀以及水资源污染等,造成了水资源的短缺.水资源关乎着人类的安全:冲突、战争因水而起;水污染威胁人类健康;水资源缺乏威胁着食品(粮食)安全;水资源制约着经济乃致社会的发展,成为人类生存的最大限制因子.
