| Research Abstract |
In order to propose an ecological management plan for Kiso rivers, 15 scientists belonging to 8 institutes were enrolled during the term of 1999 to 2001. Several new methods and important technologies had developed in the results of the project.
(1) Development of new method to evaluate basin environment
(1) New technology was developed to detect movement of land surface using satellite borne microwave SAR data (2) Technology was applied to evaluate environment of tea plantation examining insect fauna as indicator in the field with and without chemicals. (3) Change of landscape structure was analyzed by old maps and aerial photos during these 100 years. (4) Method was proposed to evaluate forest biomass judging from canopy area taken in aerial photos. (5) More precise land use classification became capable applying correction methods of solar angle and DEM on Landsat data, and it permitted to estimate nitrogen absorption in the whole Nagara river basin.
(2) Clarification of matter cycling

(6) Matter cycling was measured in an artificial needle-leaved forest, and broad-leaved forests cut in different years. (7) Also carbon storage map was created in one ha of a cool-temperate forest divided 100 sub-plots. (8) Soil respiration model for agriculture lands, and animal-grassland model for grassland ecosystem were proposed. (9) Geographical distribution of cropping system was clarified in the Kiso rivers basin.
(3) Modeling approach of matter cycle and improvement of water quality
(10) Amounts of surface-active agents outflow from river was estimated by separating agents to non-ion and minus ion. (11) Function of environment conservation was evaluated conveniently using forest planning maps. (12) Effects of vegetation cover on nitrogen outflow was evaluated by satellite data analysis and matter outflow model. According to these results, river basin management system through proposal of a guide line for environment evaluation, and decision making of conservation policy attending people living in this district.
