中文摘要 | 摘要 本研究應用2004 年14 幅之SPOT 衛星 遙測資料,監測關渡平原21 個水稻樣區常態 化差異性植生指數NDVI 之季節性變化;並 以灰關聯理論分析五種氣候因子(即累積降 雨量、平均相對溼度、日照率、平均氣溫、 與累積全天日射量)及七種空氣品質監測項 目(包括SO2、O3、NOx、NO、NO2、CO 及 PM10)對關渡平原水稻衛星遙測NDVI 之相 關性。灰關聯度與灰序為:氣溫>日射量> CO>SO2>NO2>溼度>O3>PM10>NOx> 日照率>NO>降雨量。亦即,影響關渡平原 水稻生長之二大類環境因子中,明顯的以五 種氣候因子為主,而以七種環境品質監測項 目為次。在氣候因子中則以日射量及氣溫為 主,而空氣品質監測項目中則以CO 及SO2 為主。與長期資料(1999/2-2004/5)之分析結 果相似,2004 年北投垃圾焚化廠之排放氣體 與粒狀物對關渡平原水稻生長若有影響,其 程度遠不及氣象因子所造成之影響。 |
英文摘要 | ABSTRACT This research studied the seasonal change of rice normalized difference vegetation index (NDVI) monitored by the SPOT satellite remote sensing imagery of 2004, and applied the grey system theory to analyze the relationship between rice NDVI and five climate factors including monthly cumulative precipitations, monthly mean relative humidity, daily insolation percentage, monthly mean temperature and daily cumulative irradiance, and seven air quality related items including SO2, O3, NOx, NO, NO2, CO and PM10. According to the results, the grey order were temperature>cumulative irradiance >CO>SO2>NO2>relative humidity>O3>PM10 >NOx>insolation percentage>NO>cumulative precipitation. The results indicated that climate factors play more important role in the rice growth than the seven air quality related items at Quandu Plain. Among the five climate factors, the sun-related factors such as temperature and irradiance contribute more to rice satellite NDVI than the water-related factors such as humidity and precipitation. Among the seven items for air quality, the CO and SO2 contribute more than theothers. According to the grey system theory, the waste gas and particles released by the Beitou Garbage Incinerator in 2004 make much less extent of contribution degree than the natural climate factors to the rice growth at Quandu Plain, even if they have effects. |
