Ecological Basin Management Plan for Kiso Rivers

1999年至2001年，为了提出Kiso河流的生态管理计划，8个研究所的15名科学家被招募。在该项目的成果中发展了几种新方法和重要技术。(1)开发了流域环境评价新方法(1)开发了利用星载微波SAR数据检测地表运动的新技术(2)应用以昆虫区系为指标的技术对茶园环境进行了评价。(3)利用古地图和航空照片分析了近百年来景观结构的变化。(4)提出了根据航拍林冠面积评价森林生物量的方法。(5)利用太阳角度和DEM对Landsat数据进行校正，可以进行更精确的土地利用分类，并可以估算整个长原河流域的氮吸收。(6)测定了不同采伐年限的人工针叶林和阔叶林的物质循环。(7)建立了寒温带森林1公顷的碳储量图，划分了100个子样地。(8)建立了农田土壤呼吸模型和草地生态系统动物-草地模型。(9)明确了基索河流域种植制度的地理分布。(3)物质循环建模方法与水质改善（10）通过将表面活性剂分为非离子和负离子两种，估算了河流表面活性剂的流出量。（11）利用森林规划图方便地评价了环境保护功能。（12）通过卫星数据分析和物质流出模型，评价了植被覆盖对氮流出的影响。在此基础上，提出了流域管理系统环境评价的指导方针，并为该区居民提供了保护政策的决策。少

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 … More in ecosystems(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.
