Recently, agricultural lands have been reconsidered from the view point of contribution for environmental preservation. Here, the function of these lands absorbing air pollutants is described as an example of such contribution.
Concretely, two kinds of land use analysis using the agricultural census and digitalized air-photos for accounting areal existence of agricultural lands and their change are implemented for the purpose of estimating the absorbing quantity in case study areas.
An adopted model is briefly explained at first, which estimates the quantity absorbing air pollutants of agricultural lands.
Secondly, the method of applying the model to actual data set in case study areas, is mentioned, following the data processing flow.
Finally, characteristics of the two data are discussed in the case of applying to estimation of air pollutants absorbed by agricultural lands.
As conclusive remarks, the followings can be pointed out through case data processing using personal computing system.
The agricultural census data will be helpful for a long-term trend analysis, an evaluation by a smallscaled administrative unit, and so on.
On the other hand, remotely sensed image data will be adequate for grasping more detail change on both a time scale and an areal unit of lands.
