Assessment, planning and management for coral reef ecosystems are particularly challenging tasks, especially in developing countries. In this study, a methodological approach which integrates Geographic Information Systems (GIS) and Multicriteria Evaluation (MCE) for the development of suitability assessment models for a variety of uses of coral reef resources is discussed. Such an approach is sustained by an extensive use of local expert knowledge coded in the form of automated decision trees (DTs). The usefulness of the approach and the models developed is demonstrated by their application to the participatory assessment and resources planning at “Alacranes Reef National Park” (ARNP), Yucatán, México. Overlaying of resulting suitability maps was also applied for identifying potential conflicting areas. 相似文献

During World War II, a military airport was built inside the city of Reykjavik. This airport then became the centre of domestic
aviation for the whole country. Today, 50 years later, the airport tract has become valuable for urban development. The city
government therefore wants the airport relocated. Four different sites have been considered. The first alternative is to maintain
the airport in the same place. A second alternative is based on reclaiming land alongside the present airport. A third possible
site is in a rugged lava field south of Reykjavik, and the fourth alternative is to move the domestic traffic to Keflavik
International Airport about 60 km away. The relocation has become a hot issue in the country. The people living in the countryside
want to keep the airport in the same place. On the other hand, people living in Reykjavik see the airport land as valuable
potential for urban development close to the city centre. To approach this debate in an orderly fashion, the four sites have
been studied from an environmental and socio-economic point of view. The four alternatives are classified by four different
categories: (1) economy and capital investment, (2) social impacts, (3) direct environmental consequences, and (4) public
safety. Firstly, the last three categories were evaluated and weighted, and all four alternatives graded according to their
environmental quality. Secondly, using the results of a separate cost-effectiveness study, a Pareto optimality solution is
suggested. Finally, sensitivity analysis was carried out to investigate how the “environmental” factors through their variation
can influence the final selection. 相似文献

Tetracycline (TC) is a widely used veterinary drug in animal breeding and fishery. Because of its low bioavailability, the TC residue extensively exists in the environment (e.g. soils, lakes and rivers), which can enter the human body, being potentially harmful. Hemoglobin (Hb) is a protein responsible for oxygen carrying in the vascular system of animals. The aim of this study was to investigate the interaction of bovine hemoglobin (BHb) with TC through spectroscopic and molecular modeling methods. The experimental results revealed that TC can interact with BHb with one binding site to form a TC-BHb complex, mainly through van der Waals interactions and hydrogen bonds. The UV-visible absorption, synchronous fluorescence, and circular dichroism (CD) results revealed that the binding of TC can cause conformational and some microenvironmental changes of BHb, which may affect BHb physiological functions. The synchronous fluorescence experiment disclosed that TC binds into BHb central cavity, which was verified by molecular modeling study. The work contributes to clarify the molecular mechanism of TC toxicity in vivo. 相似文献

"十一五"是新疆经济飞速发展的五年,同时也是重大生态保护工程十五实施期。本文采用国家环境保护部制定的《生态环境状况评价技术规范》(HJ/T192-2006)分别对新疆"十五"末与"十一五"末生态环境质量进行综合评价分析。结果显示:塔里木河流域生态环境质量总体处于较差水平,各县(市)生态环境质量以较差和差为主,二者面积总和在全区总面积60%以上;与"十五"末相比,全区生态环境质量保持稳定,无明显变化。呈现总体趋于稳定,局部区域有所改善的特征。 相似文献
