| Summary: | 碩士 === 國立臺灣大學 === 環境工程學研究所 === 96 === Globe warming most possibly resulted from the emission of greenhousegas (GHG) of human activities. The GHG emission from domestic waste and agriculture activities was much less than from energy and industrial, the
inventory of GHG emission could establish the emission baseline and suggest which we can reduce the GHG emission. Forest is the important carbon sink, the inventory can show how much carbon absorbed by forest.
Taoyuan is a rapidly growing city. It was with big trouble in domestic waste in the 1990s. This research takes the domestic waste treatment, agriculture and forest activities in Taoyuan as a case with real data to inventory the GHG emission and absorption in Taoyuan.
The result shows the GHG emission from per ton waste treated by landfills is large than by incinerator, but emission of per ton waste-per day is large in incinerator than in landfills. The average emission from waste is 0.16
ton Carbon dioxide equivalent (CDE) per year-per person in 2002-2006. The GHG emission of agriculture activity was mainly from agriculture soil (N2O,mostly from use of chemical fertilizer), enteric fermentation (CH4) and rice
cultivation (GH4). The absorption of CO2 of land use and forest (LUAF) is 42.4 ton CDE per year in 2000-2006, and the average CO2 absorption is 10.03 ton CDE per hectare of forest land. The absorption of GHG from LUAF is
roughly large the emission from waste and agriculture.
There''re good suggestions of reducing waste, recycling waste, forestation, rational fertilization, and changing flooding habits in paddy soils to reduce the GHG emission. And it''s necessary to develop the local coefficients of GHG emission and absorption.
