The paper is a case study on Evaluation of tourist development potential with a focus on Awaji Island. Through investigation of the past research 4 indicators of the envaluation were used. The research was made in anattempt to evalute the tourist development potential in terms of the actual tourist conditions and the trend of tourist development. These were analyzed and evaluated in terms of 「Variety」 of tourist resource, 「Convenience」 of transportation. 「Capacity」 of accommodation, and 「Utilizable land space」 of existence for the tourist development. By means of quantitative analysis and estimation of the indicators, it has become clear that there is changing of tourist development potential and further that there was no possibility of the potencial in Mihara town as opposed to Sumoto city there was the most possibility for the purpose of the tourist development potential. As a result, the study acquired basic data available for an integrated evaluation of the tourist development potential.

This study aims to clarify the interrelationship between the physical or social conditions of the block park and residents' utilization of block park or the reasons of sellecting the parks. The physical conditions are the distance from residents to the block park and the inner condition of the block park, and the social condition is the pattern of residents' daily activities. It is clear that some of residents do not always use the nearest park when the redidents use the block park. This reason is that the sellection of the park is effected by the accesibility to the park, the residents' perception of the real distance to the parks nearby, and the conditions relating to greenery condition and the maintenance level of facilities.

This study intends to obtain the knowledges regarding the conservation of rural landscape in the future by means of cognitive evaluation, based on clarifying the relationship between the spatial characteristics of rural spaces which are affected by various developments and the rural landscape. A small drainage basin is defined as an eco-unit in this study. From this study, it is clear that the important factors on evaluation of rural landscape are the topography character and landuse characteristics which rural spaces hold. Especially, it is suggested that keeping not only the structure of valley but also the interactive landuse of cope and rice paddy is significant for the evaluation of rural landscape. So it can be said that preservation of a series of landuse types based on the structure of valley is needed to conserve the beautiful rural landscape.

The pupose of this study is to develop a methodology for designing urban riverfront space from the viewpoint of incorporating urban space with riverfront space, when super embankment along the river will be contructed. The method used in this study is the cognitive evaluation by means of simulation models. The simulation models are established through computergrahics which can be used in response to the change of viewpoint and view direction. Through this study the following findings are obtained. Firstly, total coordinating urban space with riverfront space plays an important role in creating a desirable landscape in riverfront space. Secondly, it is most important for the good sence of scale of the riverfront space that the river alignment is designed in a form of a curve line and a ratio of the width of river to the height of the buildings along the river is about 3.0. Finally, from a standpoint of the amenity, it is very effective to plant the lawn on both floodplain, embankment and the talltrees on frontyard of buildings.

This study aims, through the case study in Sakai city, to classify the agricultural lands in urban area according to their existing formation and to clarify the interrelationship between their existing formation and the ecological function evaluation of the agricultural lands as green areas based on the consciousness of residents through the questionnaire survey. The results of this study are summarized as follows ; 58 elementary-school districts are classified into 7 groups according to the existing formation of agricultural lands. Concerning the relationship between the existing formation of agricultural lands and their various effects, the ecological function to conserve nature of agricultural lands as the green areas is evaluated the highest one, and the ecological functions to conserve scenery and to control microclimate of the area follow next. The gathering area of paddy field is evaluated as the highest one in all the types of the existing formation of agricultural lands.

The purpose of this study is to develop a methodology for designing riverfront space which focuses on conserving and creating identity of river.This study is achieved from the viewpoint of water expression spatial nature and river alignment of the riverfront space. The method used in this study is the cognitive evaluation by means of simulation models. The simulation models are established through photomontage using an image processing system. Through this study the following findings are obtained. Firstly.it is the most important that the river alignment is a main factor for conserving and creating identity of river in cognitive evaluation. Secondarily,it is suggested that not only a curved line of river alignment but also a surface feature of the river naturalness is important for conserving and creating identity of river. Finally, the landscaping on floodplain plays an important role in creating a desirable riverfront.

Japan has rapidly shifted toward an aging society in recent years. But in relation to this, environmental and service facilities have been criticized as lagging. In this study, the views of elderly people in the main were compiled with regard to residential environment in the new town and the old town. By clarifying the degree of adequacy, the environmental adjustments and facilities needs to respond to the aging society were brought to high. Majore findings of this study are follows. In the new town, though the degree of environmental adequacy is high, elderly people desire safety roads and resorces of local history. Elderly people without a regular occupation require elderly health facilities and elderly people who live in the family type of single-generation demand area activities. In the old town, for elderly people who tend to be restricted to their immediate neighborhood, it is most important to increase the quality of environment.

The purpose of this study is to clarify the interrelationship between the physical conditions of the conserved forest existed in the newtown and the residential responses to the conserved forest conducted by questionnaire survey from the viewpoint of landscape, utilization, and natural supplying characteristics for the future use of the conserved forest.As a result,it is clear that the evaluation structure of residents is influenced by public availability,accessibility, and visible opportunity relating to the location of conserved forest.It can be also concluded from the viewpoint of the evaluation that the loose slope of topography and well-strutured footpath are very important factors for theirutilization characteristics,and the high density and diversity of arbor layer.and the twolevel forest in height play an important role in their contributing to the landscape and natural supplying characteristics.

This study aims to clarify the existing effects of green space relating to consolidation of residential environment by conducting questionnaires on the residents around the green space. The results of this study are summarized as follows ; 1) The evaluation to the existing effects of green space is the highest at the naturally supplied green areas, and amenity effects follow next. The range of these two effects is wide. 2) The evaluation to the micrometeorological control effects and the noise reduction effect is lower than the afore-mentioned two effects, and the range of the effect is narrow. 3) The more there are visible green space and frequency of human green contact, the higher the evaluation to the existing effects of green space becomes.

The purpose of this study is to develop a methodology for designing urban riverfront space which harmonizes land use consideration and landscape features. The method used in this study is a cognitive evaluation by means of simulation models. The simulation models were produced through photomontage using an image processing system. Through this study the following findings were obtained. In the district of high rise apartment, a gradually inclined embankment and a stair-formed embankment are highly evaluated and it is desired that approchability of water be promoted to reinforce access to the waterfront. In the commercial district, landscaping with appropriate verdure, especially tall trees, is highly evaluated regardless of the structure of embankment. Here landscaping-oriented design is more desired than approchability of water. In the business district, both approchability of water and landscaping play an important role for a desirable riverfront.

The intention of this study is to develop a methodology for designing riverfront spaces which focus on creating attractiveness and naturalness. The method of this study is a cognitive evaluation of twelve simulation models. The simulation models were made by photomontage using a image processing system three cross-sectional compositions were used and each cross sectional model has several different material composition. Through this study the following major result was obtained : The model which had a gradually inclined embankment covered with lawn and which has an exposed river bed covered with lawn and its embankment covered with ivy are excellent for creating both attractiveness and naturalness.

The aim of this study is to obtain some knowledges about the method of landscape planting of the street using the photomontage method based on relationship between public greenery and semi-public greenery at roadside. It becomes clear as follows;1) Regarding landscape planting at public space, as the volume of branches becomes bigger, it makes the evaluation of the streetscape higher. Especially this tendency is stronger on the condition of bad facade. And it is more effective to plant at the center of the street. 2) Regarding landscape planting at semi-public space like a roadside, landscape planting is useful to rise the evaluation of the streetscape. And the effect of landscape planting is higher on the condition of good facade than on the condition of bad. Concerning planting formation, it is very interesting that the formations of bushes and high trees are evaluated same on the condition of good facade.

This study attempt to evaluate the recreational value of various open spaces (forest, waterfront space, and free open space) located in the natural park based on clarifying the relationship between the physical conditions of these open spaces and human responses (users'activity pattern, users' cognitive evaluation and feeling of satisfaction). On this standing point, it was proceed analyses using the informations which were collected by interviews to users who were in these open spaces at the natural park of Osaka Prefecture. Through this study, the following findings were obtained ; 1) In the forest, the evaluation of openess is low but the evaluation of naturalness is high according to the type of forest. 0n this occation, the forest is used for the nature watching and education. 2) In the free open space, the feeling of openess and comfortable is high. Flat free open space is used more statically and slope below 5°〜8° slope is used more restful. 3) The stream of waterfront space improve the feeling- of comfortable and the falls is used more visually.
