現存植生環境動態図の作成とその活用に関する基礎的研究(平成9年度 日本造園学会研究発表論文集(15))

It is necessary to identify the current situation of our rural land in the context of the limited natural resources and environmental capacity of the Earth. The actual vegetation map indicates such stand conditions as climate, soil, and historical human impacts. However, current vegetation mapping needs to add further information to indicate the potential of existing vegetation for multiple environmental conservation function. This study attempts to developed a more practical vegetation mapping method based on image processing of aerial photographs. This case study of a dynamiv vegetation map illustrates three levels of rank including tree height, branching width, and tree stand density. From the analysis of this dynamic vegetation map, a tentative vegetation diagnosis map was also developed for designating five categories of conservation functions or situations of actual vegetation which are: 1) sustainability, 2) air quality, 3) landscape, 4) biodiversity, 5) biomass.
