中文摘要 | 九二一集集大地震造成山坡土石鬆動,尚殘留於坡面或堆置於坑溝溪谷四周,成為土石流之主要土石來源。桃芝颱風在溪頭地區造成豪雨,進而觸發土石流,在園區內外共有17處之多。由於溪頭自然教育園區對於地方觀光產業佔有舉足輕重的地位,難於封山育林,必要透過適當的工程手段,以有限的經費實施適度的工程建設,雖無法消弭未來土石流的發生,然應可減輕其危險性與災害性。尤其溪頭為著名的觀光勝地,工程設計並應符合景觀、遊憩、生態園區之考量。 民國88年以前溪頭自然教育園區每年之入園人數介於80萬至100萬之間,在民國88年發生921地震,以及90年桃芝颱風,造成民國89年及民國90年間入園人數銳減為28萬與34萬,在完成溪頭園區整治工程後,除了舊有景點外,亦配合土石流大自然力量創立新的景點,在民國95年之後,每年入園人數皆在百萬人以上。 |
英文摘要 | ChiChi Earthquake, occurred on September 21, 1999, caused a dramatic damage in Sitou Nature Education Area. The earthquake led to a large number of rock falls and unstable rock blocks on the slopes and valleys that could produce the sources for the following debris-flow events. Typhoon Toraji that occurred in 2001 then induced 17 valleys with severe debris flows. Since Sitou Nature Education Area is one of the most important landscapes in Taiwan, it is not possible to permanently close for forest recovering. Hence, the recreation activity and the ecological-orienting engineering restorations were managed simultaneously. Before 1999, the amounts of annual tourists were around 80 thousands to 1 million in Sitou Nature Education Area. The amounts of annual tourists dropped to 280,000 and 340,000 during the years of 2000 and 2001. With the forest recovery and the establishments of new scenic spots that were intentionally built for representing the natural power of earthquake and landslide, the amounts of annual tourists were continually increased since 2002 and were over 1 millions since 2006. |
