中文摘要 | 本文之目的擬由集水區現場調查分析,以了解土地開發利用對水質的影 響,以及其對水庫使用之具體影響。集水區內,土地的不當使用為造成水質惡化 的主要原因,本研究即在探討仁義潭水庫上游之八掌溪流域內土地利用對水質的 影響。除實施土地利用之調查外,並就支流獨座溪集水區與八掌溪主流至仁義潭 水庫進水口間,選取12個採樣點,進行水質分析。採樣頻率為每二個月一次,分 析項目包括pH,SS,COD,Cl-,NH��-N,NO��-N,NO��-N,TP,ABS,Na+,K+,Mn��+,硬度 等,此外,為了解部分微生物情況,亦進行大腸菌群分析。文中將整個集水區依 實際情況分為若干子集水區以利作物影響之探討,調查與分析結果顯示,茶園與 檳榔園之土地利用方式,對溪水中氨氮與總磷的含量有重大影響。 |
英文摘要 | The purpose of this study is to investigate the effect of the land use insidethe reservoir watershed on the stream water quality and on the usage of thereservoir. The Pa-chang stream in Chia-yi, Taiwan was selected as theinvestigated field. The species of plants cultivated in this area areinvestigated in this study. Betel-nut and tea are the predominant plants cultivated here. The water quality of the stream is analyzed bimonthly. Thewhole watershed is divided into many subwatersheds in order to betteranalyze the effects of plant cultivation on stream water quality. The resultsof field investigation and the analysis of water quality show that the landunder cultivation by tea and betel-nut plants in this watershed has a great effect on the concentrations of phosphate and nitrogen compounds in the streamwater. It is an important factor in the eutrophication of the two off-channelreservoirs in the watershed. |
