Development of a Methodology for Strategic Environmental Assessment: Application to the Assessment of Golf Course Installation Policy in Taiwan

Some countries, including Taiwan, have adopted strategic environmental assessment (SEA) to assess and modify proposed policies, plans, and programs (PPPs) in the planning phase for pursuing sustainable development. However, there were only some sketchy steps focusing on policy assessment in the system of Taiwan. This study aims to develop a methodology for SEA in Taiwan to enhance the effectiveness associated with PPPs. The proposed methodology comprises an SEA procedure involving PPP management and assessment in various phases, a sustainable assessment framework, and an SEA management system. The SEA procedure is devised based on the theoretical considerations by systems thinking and the regulative requirements in Taiwan. The positive and negative impacts on ecology, society, and economy are simultaneously considered in the planning (including policy generation and evaluation), implementation, and control phases of the procedure. This study used the analytic hierarchy process, Delphi technique, and systems analysis to develop a sustainable assessment framework. An SEA management system was built based on geographic information system software to process spatial, attribute, and satellite image data during the assessment procedure. The proposed methodology was applied in the SEA of golf course installation policy in 2001 as a case study, which was the first SEA in Taiwan. Most of the 82 existing golf courses in 2001 were installed on slope lands and caused a serious ecological impact. Assessment results indicated that 15 future golf courses installed on marginal lands (including buffer zones, remedied lands, and wastelands) were acceptable because the comprehensive environmental (ecological, social, and economic) assessment value was better based on environmental characteristics and management regulations of Taiwan. The SEA procedure in the planning phase for this policy was completed but the implementation phase of this policy was not begun because the related legislation procedure could not be arranged due to a few senators’ resistance. A self-review of the control phase was carried out in 2006 using this methodology. Installation permits for 12 courses on slope lands were terminated after 2001 and then 27 future courses could be installed on marginal lands. The assessment value of this policy using the data on ecological, social, and economic conditions from 2006 was higher than that using the data from 2001. The analytical results illustrate that the proposed methodology can be used to effectively and efficiently assist the related authorities for SEA.

火源位置对浮法玻璃热破裂行为规律影响研究*

为了研究火源位置对浮法玻璃热破裂行为规律的影响,选用尺寸为600 mm×600 mm×6 mm（长×宽×厚）的浮法玻璃为研究对象,研究在点支撑和框支撑安装方式下,在玻璃厚度方向上不同火源位置的浮法玻璃热破裂情况,分析其首次破裂时间、破裂时表面温度以及裂纹起裂方式等热破裂行为参数,加深对浮法玻璃热破裂行为机理的研究。结果表明:在火源位置实验中进行中心热辐射时,点支撑安装方式下的浮法玻璃防火性能优于框支撑安装方式下的浮法玻璃;其次,玻璃表面会形成大量孤岛裂纹和交叉裂纹,裂纹最终形态受火源位置影响,火源位置与裂纹数量、裂纹分布复杂性呈负相关。
