中文摘要 | 山葵是一種喜陰濕環境的十字花科多年生作物,通常栽培於高冷地之杉林下,是故曾文水庫集水區內的阿里山地區頗適合山葵生長。因山葵種植面積愈來愈廣,加上民間環保意識的提升、政府單位的重視,在阿里山地區此種林班地農用對水土資源污染之影響就逐漸受到社會大眾的關切。本研究之目的即是以位於曾文水庫集水區內的阿里山山葵園為對象,研究山葵園土地利用對水庫水質之潛在影響。研究顯示,山葵園的確帶來污染,其中,逕流水的電導度平均值約為森林水的7倍、酸度2倍、鹼度12倍、濁度4583倍、化學需氧量11512倍、氨氮471倍、有機氮1166倍、凱氏氮1284倍、硝酸鹽氮3倍、亞硝酸鹽氮150倍、總氮46倍,及總磷639倍。由此可知,山葵園除造成土壤沖蝕嚴重外,亦因大量施肥,造成水中碳、氮、磷濃度大幅增加,故山葵園的污染相當可觀,對曾文水庫水質污染潛能實不容忽視。 |
英文摘要 | Wasabi (Wasabia Japonica Matsum) is a cross-flowering and perennial plants favoring the wetenvironment under the shadow of forests. They are usually planted under the fir forest in the high andcold place. Therefore, A-Li mountain in watershed of Tseng-Wen reservoir is suitable for Wasabi's growth. Due to increasing Wasabi planting, environment protection consciousness, the effects offorest compartments used as agricultural lands in A-Li mountain on soil and water resources havedrawn concern by the public and the government. This study is to investigate the effects of Wasabigrowing in A-Li mountain on reservoir and water characteristics. The results show that Wasabi is asignificant source of reservoir contamination. Among others, conductivity means of Wasabi runoffareabout 7 times that of forest water. The others are acidity 2 times, alkalinity 12 times, turbidity 4583times, chemical oxygen demand 11512 times, ammonia nitrogen 471 times, organic nitrogen 1166times, total kjeldahl nitrogen 1284 times, nitrate nitrogen 3 times, nitrite nitrogen 150 times, totalnitrogen 46 times, and total phosphorus 639 times, respectively. Apparently, Wasabi farms not onlycauses several soil washout but also increases carbon, nitrogen, and phosphorus concentrations ofwater greatly due to applying large fertilizers. Consequently, the effects of Wasabi planting onreservoir and water characteristics are significant. |
