Notes
An investigation on natural environment was carried out. Referring to the natural grade map presented by the Ministry of Environment, the five factors which would be expected to affect the environmental change were examined with multiple regression analysis. The factors above mentioned were as follows : (1) population ; (2) density of road ; (3) altitude ; (4) undulation ; and (5) distance from railway station. These factors are classified into three groups. The first two factors are concerned with the social situation, the next two with the natural situation and the last one is related to the situation of various conveniences of traffic. The proportions of each variate to the natural grade were calculated with the stepwise method. Consequently, it was recognized that the density of road as well as the altitude had the marked effects on the natural grade. With introducing these two variates into the quantitative analysis, the value of 0. 76 was obtained as the multicorrelation coefficient. It is confirmed that the linear multi-regression model is available to analyze the environment of the developing town such as in this case.
自然という漠然としたものに若干の考察を加えた.環境庁の調査になる自然度調査図を参考に,自然の変容に影響をおよぼす要因について重回帰分析を行なつた.要因には,自然因子として標高,起伏量の2種,社会因子として人口密度,道路密度の2種,距離因子として駅からの距離の1種を用いている。分析では段階的手法を用い,危険率1%の基準を設けて偏回帰係数のF一検定を行なつた.その結果,道路密度,標高の2要因が残つた.このときの重相関係数は0.76であつた.以上のことから,この事例のような発展途上にある町村の自然環境を解析する際には,重回帰モデルが有効であることが認められた.
