The vulnerability analysis method has been widely used in many environmental fields. In recent years, the tool has succeeded in comprehensive assessment of environmental problems. This study applied the vulnerability and resilience analysis method on watershed conservation and grasped the environmental change capacity that watershed could bear. The Fei-tsui reservoir watershed in Northern Taiwan provided the setting for the case study reported herein. This study considered both internal and external effect factors, including watershed vulnerability, rainfall energy and the distances between the outlet and subbasins, and developed a new index, WP, for the priority restraints strategies on the land-use activities. The land-use restraint index can be a significant criterion for watershed protection and management strategies. 相似文献

To ease the NIMBY (not in my back yard) syndrome of constructing municipal solid waste (MSW) incinerators in Taiwan, compensatory funding is widely allocated to the impacted communities to gain the acceptance and support of residents living the impacted areas. This paper presents a spatial methodology for distributing a compensatory fund more logically based on the environmental impact on each neighborhood in Taipei City. This method integrates ten impact factors, which have been proposed by a local committee, to evaluate all neighborhoods using mathematical models combined with spatial analyses in an analytic hierarchy process. The compensatory fund is distributed according to the resulting final scores. A GIS (geographic information systems)-based system has been developed to assist in assigning the final scores to the neighborhoods impacted. Results on impact factors and fund distributions are combined; they are included in an information system and displayed in spatial scales. For Taipei City, the impact of air quality during the incinerator operating period is the item of greatest concern to the surrounding residents and thus, it receives a relatively higher weight of 0.2894. As a result, high impact scores were assigned to not only those neighborhoods hosting the incinerators, but also the neighborhoods where the maximum particulate air pollutants occurred. This approach could be applicable to other MSW incinerators with similar environmental impact problems and interest in compensation schemes. 相似文献

It is significant to design best management practices (BMPs) and determine the proper BMPs placement for the purpose that
can not only satisfy the water quantity and water quality standard, but also lower the total cost of BMPs. The spatial rainfall
variability can have much effect on its relative runoff and non-point source pollution (NPSP). Meantime, the optimal design
and placement of BMPs would be different as well. The objective of this study was to discuss the relationship between the
spatial variability of rainfall and the optimal BMPs placements. Three synthetic rainfall storms with varied spatial distributions,
including uniform rainfall, downstream rainfall and upstream rainfall, were designed. WinVAST model was applied to predict
runoff and NPSP. Additionally, detention pond and swale were selected for being structural BMPs. Scatter search was applied
to find the optimal BMPs placement. The results show that mostly the total cost of BMPs is higher in downstream rainfall than
in upstream rainfall or uniform rainfall. Moreover, the cost of detention pond is much higher than swale. Thus, even though
detention pond has larger efficiency for lowering peak flow and pollutant exports, it is not always the determined set in
each subbasin. 相似文献
