This studies suggest The Nature Circle (N. C.). This index is a fundamental index, and can utilize it in the development evaluation of natural area. N. C. is the greatest circle that is drawn not to contain the development place. N. C. is made on an enough numerical point in an area. We can evaluate scale and influence of development in natural area by observing a radius and an area of N. C., According to five factors which let index value change, we showed a characteristic of index value by observing a condition of change of index value. We measured index value next as an object place Mt. Fuji foot, and considered the effectiveness of index.
