Geographical areas constitute the basic implementation locus for integrated coastal zone management strategies and activities.
Because the definition of territorial planning objectives may be affected by socioeconomic and environmental characteristics,
one of the main steps in the process involves dividing the coast into homogeneous environmental management units (HEMUs).
This article presents a general and simple method for regionalizing the landside of a coastal zone into HEMUs and illustrates
it through application to the Catalan coast. Socioeconomic and natural (biophysical) subsystems were selected as the most
appropriate dimensions of the regionalization process. Dimensions were described using 11 spatial themes, which were managed
in a geographic information system environment that proved to be an adequate tool for the purpose. A final coastal zone map
of four classes of HEMUs connected to local administrative units was obtained, and because it reflects the current natural
and socioeconomic dynamics, it can be considered as an initial step in the planning process for the Catalan coast. Although
the proposed method was developed based on the characteristics of the Catalan coast, it is general enough to be adapted and
applied to most developed or developing coastal areas. 相似文献

The International Safety Management (ISM) Code defines a broad framework for the safe management and operation of merchant ships, maintaining high standards of safety and environmental protection. On the other hand, ISO 14001:2004 provides a generic, worldwide environmental management standard that has been utilized by several industries. Both the ISM Code and ISO 14001:2004 have the practical goal of establishing a sustainable Integrated Environmental Management System (IEMS) for shipping businesses. This paper presents a hybrid design methodology that shows how requirements from both standards can be combined into a single execution scheme. Specifically, the Analytic Hierarchy Process (AHP) and Fuzzy Axiomatic Design (FAD) are used to structure an IEMS for ship management companies. This research provides decision aid to maritime executives in order to enhance the environmental performance in the shipping industry. 相似文献

The Suzhou Creek Rehabilitation Project (SCRP) is one of the largest water-related environmental rehabilitation schemes ever undertaken in the vicinity of Shanghai, China. This paper details the development and application of a River Environmental Decision Support System (REDSS) for scientific planning and decision-making on the Suzhou Creek project, and illustrates the flexibility of the REDSS framework. We developed the following components: (1) a GIS-based analysis employing Component technology; (2) a "data mart" for multi-dimensional, multi-level, integrated, dynamic, and flexible data querying; and (3) a set of hydrodynamic and water quality models which can simulate complex tidal river networks. In addition, we detail how a water quality assessment model is embedded into the REDSS by employing an Identification Index Method. With the REDSS, all GIS and non-GIS components are integrated seamlessly and data from different sources can be queried simultaneously. This allows for various scenarios to be simulated and analyzed in advance to predict and assess the effects of proposed engineering and management measures. Generated information can thus support effective decisions. All operations of the REDSS can be implemented conveniently through user-friendly interfaces. The function of the REDSS framework is demonstrated through an application to Suzhou Creek. Because the REDSS characteristics are quite general, it may be applied in different geographic regions. 相似文献
