In recent years, there have been conflicts with local residents in Japan over issues such as landscape and disaster risk caused by the construction of solar-PV facilities. In order to promote the suitable installation of solar-PV facilities in the future, it is necessary to clarify resident attitudes toward such facilities, not only in the planning stage but also in operation. In this research, a questionnaire survey was conducted among local residents living near a solar-PV facility in operation (that had had conflicts in the planning stage) at Mt. Tsukuba, in Tsukuba city. In addition, a model of resident attitude formation toward the facility was constructed and its determinants were clarified. As a result, it was found that the felt annoyance due to landscape change had a statistically significant relationship with the negative attitude to the project. Moreover, it was also demonstrated that the installation in Mt. Tsukuba was a significant correlated factor with the felt annoyance due to landscape change. The analysis confirms that it is important to avoid installation in mountainous forests of special value to residents, such as Mt. Tsukuba, in order to improve the acceptance from local communities toward solar-PV projects.

The empirical model for estimating stand volume from LiDAR was developed by Takejima (2015). The study introduced new concept of Stock Ratio, the ratio of the stand volume in the spatial volume occupied by trees. The analysis of field data of over 6,000 trees revealed that Stock Ratio can be descripted by species and Hart-Becking index (Sr). However, the model had a problem for practical use, because of its adaptability since the base parameter was relying on the particular field data. To solve this problem, Stock Ratio simulation was adopted in this study. It was realized by calculating stem volume and spatial volume from virtual tree model. As a result, the generalized stand volume estimation functions were established. Functions are v={0.0270e(-0.2140×Sr)+0.00217}V (Sugi : Cryptomeria Japonica stand) and v={0.0226e(-0.2485×Sr)+0.00207}V (Hinoki : Chamaecyparis Obutsusa stand) where v as stand volumes, V as spatial volume calculated from LiDAR data. With the use of these functions, the stand volume of Sugi and Hinoki can be appropriately estimated without field data, which was essential in conventional methods.
