The Reuse of Urban and Industrial Waste in Tai-Lin-Pu Reclamation Project, Taiwan

This study introduces the principles of KMG's (Kaoshiung Municipal Government) dealing with the non-poisonous urban and industrial waste through reclamation of shore land in reinforcing a sense of coastal protection and land development in Tai-Lin-Pu coastal area, southern Taiwan.

Through a series of experimental studies, we found that substitutes of coarse aggregate with a broad spectrum of integrating slag powder, fly ash, and cementitious material can be obtained with a benefit up to 80% saving of cement. the integrated aggregates from the non-poisonous industrial wastes were subsequently made into armour units and used in the field tests at Tai-Lin-Pu coastal area, where the shorelines are seriously eroded. After being subjected to several severe typhoon advents, the results showed that the waste-made units used as the protection breakwater, together with construction wastes and excavated soil as the filling material, prove to be an effective practice in utilizing recycled urban waste to reclaim erosive shore lands. Moreover, this study also demonstrates that through detailed analysis of the waste characteristics, scrap material could be turned into valuable construction aggregates, and highlights the value of non-poisonous urban and industrial waste as a alternative resource for the shore protection engineering.     

福建“金三角”经济区域综合防灾策略研究

以海峡西岸闽南“金三角”经济区(简称为“西岸金三角”)为对象,重点针对该区地理位置、地形地貌、水文地质、文化传统、交通布局和城市规则等方面的主要特征,总结、分析和研究灾害的主要类型、已灾教训和潜在危险及其趋势;经系统研究,预测未来灾害的基本形式;着重分析未来灾害出现的可能性及其损失程度;从区域基本建设角度出发,科学地提出了防灾、减灾、救灾,乃至重建及其预警的主要举措和基本策略,特别提出了数字区域、信息档案、安全规划、应急预警等先进、科学和合理的理念、方法、技术和措施在区域综合防灾中的应用。为工程实践、经济计划、投资决策和规划管理提供科学依据。     

闽台耕地非农化及关联因子的比较研究

土地利用/覆盖变化的区域对比分析被国际地理学联合会LUCC工作组列为2000～2004年期间的三大研究目标之一,闽台因其区域自然背景及历史文化的相似性和经济发展时序递差性成为区域对比研究的理想对象之一。利用闽台相关统计资料对比显示,福建1979～2001年与台湾1969～1998年的耕地非农化呈现周期性变化。对影响耕地非农化因子进行灰色关联分析,结果显示:人口增加及城市化水平提高、农业发展共同构成闽台耕地非农化的第一、二驱动因子;经济发展水平影响闽台耕地非农化的规模与利用效率,从同一时点比较,福建非农化土地利用效率远低于台湾,但就同处于工业化中期的发展阶段比较,福建非农化土地的利用效率明显高于台湾;农副产品的对外贸易量对台湾耕地非农化的影响强于福建。最后分析了闽台不同经济发展时期经济发展政策与土地管理法规对耕地非农化的影响。
