The purpose of this study is to find out what comfortable images of forest are. A questionnarie was made using a semantic differential technique, which was handled to recreationists who visited Oku-Nikko. The questionnarie was written in by the recreationists were analyzed using a principal component analysis.
The results are;
1) The recreationists felt comfortable in a deciduous forest consisting of Quercus crispula and Larix leptolepis, and on the spacious moor in Senjogahara. On the other hand they felt uncomfortable in an evergreen needle-leaved forest consisting of Abies homolepis, and on the developed lakeside of Yuno.
2) The results related to images of forest were; a. They had a more natural image in a deciduous forest with trees of the same size. b. They had an extensive image for the opened space of the moor and the lake. c. It is recognized the Yuno lake and the moor of Senjogahara are so developed that they had an artificial image exaggeratedly. d. They had a simple and monotonous image in a large area. e. They felt more uncomfortable in the forest with richness in variety.(species and density are complicated.) f. They had a soft image in a deciduous forest consisting of Quercus crispula, and a solid image in an evergreen needle-leaved forest consisting of Abies homolepis.
3) Elements were abstracted from forest images mentioned above. The elements are as follows; a. An illuminance in a forest. b. A form of trees in a forest. c. An openness of a place. d. A degree of development of a place.

Unlike most parks and recreation areas in the U. S., which have been purchased with government funds, all natural parks in Japan are designated on private-owned lands. Recently, over use of natural parks in Japan caused the destruction of nature as well as escalation of the conflict with other land uses. In order to curtail such further escalation of park over use, it is necessary to find out a method of classifying recreation resources in terms of their ability to support recreation activities, and at the same time, the effects of recreation activities on other land uses must be assessed. Otherwise, the impact of sheer number will soon destroy all natural environment and will change park landscape into urban atmosphere.
As for the case of England and Wales, the national parks and A. O. N. B.(Areas of Outstanding Natural Beauty) are also designated on private-owned lands, and similar types of problems have been raised. However, when observing planning and administrative measures of national parks and A. O. N. B., the areas are conserved as a part of whole countryside areas, in another word, not only national parks and A. O. N. B., but also the overall areas in England and Wales are conserved in their natural beauty and amenity based on the Act of Town and County Planning. Furthermore, particularly, national parks have been conserved and promoted its recreation provision under National Parks and Access to the Country-side Act (1949), Countryside Act (1968). Recently by the enactment of Local Government Act (1972) the management of nationl parks have been more greatly progressed.
Two distingushied points are:
1. Construction of National Park Planning Boards and Committees with national park officers in each national park.
2. Planning of National Park Plan formulating their policy for the management of the Park anb for the exercise of the function as respects the Park.
Obviously, in our country, Natural Parks Law exists and all national parks and natural parks are preserved by the Law, and Industrial development within the areas have been fairly controlled by the Law. Recently, however, visitors pressure, recreation development by landowners and other current problems are far beyond the control of the, Law.
Under such condition, one suggestion to solve the problem is rezoning of national parks and provisions of other new recreational areas for people in urban areas such as Country Parks and Forest Recreation Parks in Great Britain. Moreover, we urgently need fundermental planning law of lands, at the national level just like the Act of Town and Country Planning in England and Wales.
In order to embody this idea into practice, we must renew zoning systems of our lands and reconsider Master Plan of natural parks by identif ying types of land use properly. Furthermore, we must consider appropriate land use plan in terms of nature conservation and recreation resources compatible with other land uses.

There are some approaches to land use plannings, but most of them are discussed from the sides of city and economical plannings. The land use plannings which were organized from the side of natural land potential are few.
Around the urbanized areas, the land use changes from natural to urbanized areas are continuously happening and it's becoming hard to keep the dynamic balances that had been held historically between natural and urbanized land uses.
In this study, the land use changes relate to natural land situations were firstly discussed and the changing processes were analysed as the Markov Chain process in case of Osaka prefecture through mesh date. The decreasing processes of natural land uses and the increasing processes of urbanized land uses are shown in figure 7 and 8. Here the tendency of decreasing processes of natural land uses were analysed relate to the increasing processes of urbanized land uses, but the details could not be analysed because the mesh size (about 500 m × 500 m) was too large and the accuracy of mesh data was not severe enough theoretically.
The mechanism of land use changes were discussed here, but there should be more elements that relate to land use changes and more strict land use controls would be needed to natural land potentials.
