Takehiro MORIMOTO, Yuji MURAYAMA, Akio YAMASHITA, Kazufumi FUJITA andHiromasa WATANABE

Abstract: The purpose of this study is to examine the covariation between the ratio ofcultivation abandonment and several environmental indices from the geographical pointof view in Kanto Region, Japan, with small area statistics and GIS. The data sources arethe rural community statistics of the agricultural census 2000 and the vector data of ruralcommunity boundary. The results are described as follows; 1) the mean and medianvalues of the abandonment ratio increase with the rise of altitude up to about 900 meters,2) those values also increase with the distance from the center of Tokyo increases within
about 140 kilometers, and 3) those values also covariate with the other indices.
