Aerial Photo-interpretation of Natural Forests

Abstract

An interpretation of the type of the Doto natural forest was carried out by an aerial photograph (1/20, 000) taken in July 1969. We would be happy if this could become a material to study forests from the stnadpoint of the science of landscaping.
1) A similarity of fixed standards is necessary to survey forests. In the present study, we have adopted 4 interpretation factors: canopy group' tree species group, crcwn density class and tree height class. Their chief purpose is the management of natural forests, but they can also be utilized for many other purposes.
2) A forest type map prepared from fixed standards would be greatly convenient for the coordination of opinions.
3) The forest of this site of survey was good, as seen on the forest type map. This comes from the fact that an elaborate management of the natural forest was carried out.
4) The science of landscaping, as a construction technique, has a relation between the forest and the life of human beings. From this meaning, too, aerial photographs are quite effective.
