摘要

Article 3 Section 3 of the Kyoto Protocol prescribes that three types of activities - afforestation, reforestation and deforestation - are to be reported when accounting for forest sinks to compensate for greenhouse gases (GHG). This paper aims to develop a method to estimate the deforesting areas to comply with the Kyoto Protocol using remote sensing (RS) information regarding forest cover change (FCC) which include vegetation cover loss both by deforestation and forest management (FM) activity. Themethod was developed using 1990 Forestry Census and applied using 2000 Forestry Census. Apparent deforestation area assuming derived from FCC analysis using RS data, and deforestation area were calculated from Forestry Census, and regional zoning was done using Vegetation environment classification method developed by authors. Deforestation factor (a) was defined as a = (FCC-FM) / FCC. Nationwide, district- and prefectural-specific deforestation factors were calculated based on the regional zone. Deforestation area estimation using these factors, it was suggested that if smaller areas are used to calculate deforestation factors, the estimated values are more precise. But it was found prefecture as an area unit was too small to estimate deforestation factor. So cluster analysis was then conducted to group similar prefectural-specific deforestation factor to calculate the deforestation factor of each group (ac). By using 1990 Forestry Census and 2000 Forestry Census, the number of groups was 10 and 7,respectively. Estimated errors of prefectural-specific deforestation area using ac were also acceptable. This study demonstrated by using deforestation factors, deforested areas per prefecture unit is possibly estimated using the results of FCC analysisbased on RS information.
