關渡平原2004年空氣品質及氣象因子影響SPOT衛星遙測水稻生長之灰關聯分析

Grey Relational Analysis of the Effects of Climate Factors and Air Qualities on Rice Growth Monitored by SPOT Satellite Remote Sensing Data at Quandu Plain in 2004

Abstracts


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, NO(subscript x), NO, NO2, CO and PM10. According to the results, the grey order were temperature>cumulative irradiance >CO>SO2>NO2>relative humidity>O3>PM10>NO(subscript x)>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 the others. 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.
