中文摘要 | 本文運用聯合國跨政府氣候變遷 小組(IPCC)所執行未來百年之氣候預 報實驗,評估未來全球暖化對臺灣地 區水資源之可能影響。分析結果顯示, 臺灣夏季溫度於未來百年,將呈現 100%機率之偏暖趨勢,偏暖強度與未 來全球溫室氣體含量成線性對應關係, 較高溫室氣體含量對應較高暖化程度。 在夏季降雨方面,臺灣地區降雨約有 2/3 機率為偏多趨勢,但與溫室氣體含 量無線性對應關係。臺灣夏季降雨偏 多主要來自東南側洋面之颱風活動增 強,預期於2100 年侵臺颱風將倍增, 帶來更多颱風雨。颱風所帶來豪大雨, 不易為臺灣現行三大水資源系統(水庫、 河川水、地下水)所用,且會危及其執 行效率,因此建議強化建置家庭式與 社區性的水資源小系統,以達充份運 用水資源之效。 |
英文摘要 | The possible impacts of global warming on future water resources in Taiwan are surveyed from the climate prediction experiments conducted by the Intergovernmental Panel on Climate Change (IPCC). Analysis results show that future summer temperature in Taiwan has a 100% chance of significant warming. The warming intensity is proportional to the concentrations of green-house gases. The future summer rainfall tends to have a 2/3 chance of significant increase. The increasing intensity is independent of the concentrations of green-house gases. The major processes of increasing summer rainfall appear to be related to more typhoon activity over the oceans to the southeast of Taiwan. Severe typhoon rainfall cannot be efficiently used by the current major water resource systems, including reservoirs, rivers, and underground water. On the other hand, it may deteriorate the present water resource operations. It suggests to broadly establish individual small water resource systems in family and community to increase the total efficiency of water resource operation. |
