At present, the landscape construction industry in Japan is recognized as an industry having comprehensive performance abilities socially and legally. This paper is intended to clarify the process of its formation compared with the changes in the public procurement system. The modern public procurement system was formed during the Meiji period (1868~1912), and being influenced by social and economic changes, it has developed from direct management by the government to contract assignment to a supplying party. At present, a larger portion of the work is left on the performance abilities of the supplying party. The landscape construction industry also followed the same changes as above and achieved the performance abilities required by the ordering party. The present landscape construction industry has developed its performance abilities not only required by the ordering party, but also positively demonstrated its own voluntary quality control and guarantee systems. In addition, it has come to appeal for more use of its holding abilities, by transmitting the techniques it developed, such as the establishment of a voluntary qualification system, etc.

The purpose of the research is to clarify the relationship among the three factors; landscape quality, forest environment and forest stand composition with in a forest, by finding out what element of a forest environment generates comfort, and what composes within a forest environment. The forest paths of 90 years red pine forest stands (A & B) and 45 years red pine forest stand (C) (hereinafter called A, B and C) in Oshiba Park in Minami Minowa Village located in southern Nagano Prefecture, were surveyed as its research zone. B scored the highest comfort rating, and the evaluation factor leaned on the visual sense, which could be an easy-to-sense advantaged asthenia. And it has revealed that two important factors were the scenic attraction of the trees, and the random sunlight beaming through the leaves, which is appeared to be related to the fact that the kind and individual size of trees in B vary. As observed above, the two key factors have become apparent . 1.The forest environment, which governs the comfort level of an individual forest, depends on its forest stand composition.2. Although it is still used as the prime aesthesia, people value the conform level not only with their visual sense, but also with their all five senses.

We examined influences of trampling and wood-chip mulching on soil animal fauna in a Japanese beech forest with utilization as a sightseeing spot. Three study sites; a trampled area with wood-chip mulch, a trampled area with leaf litter, and a control area were settled in a beech forest. The hardness of soil and the soil fauna were compared among the three study areas on 7 September and 24 November in 2005. The hardness of the soil was significantly large in the order as the trampled area with wood-chip mulch, the trampled area with leaf litter and the control area. From the survey on soil fauna, Pseudoscopiones and Harpacticoida were not observed in both trampled areas on 7 September and 24 November in 2005. The number of families of oribatid mites and that of collembolan species were larger in the control area than those of trampled area. Diversity of collembolan species the soil was high in the order as the control area, the trampled area with leaf litter and the trampled area with wood-chip mulch.
