项目摘要

Secondary grassland was cited as an important element of Japan's national strategy on biodiversity. In addition, secondary grassland has a particular landscape and is an important component of landscapes in natural parks. Moreover, secondary grassland has multidimensional value such as cultural value. A total of 2,300 ha of secondary grassland remains in the Kirigamine district of the Yatsugatake Chushin Heights quasi-National Park, the target area. This area is an important region in terms of preservation of biodiversity and is extremely valuable as a regional landscape for vegetation like Hemerocallis middendorffii var. esculenta.Secondary grassland had been maintained through cutting and carrying away of vegetation and intentional burning, but the tendency for it to turn to woodland along with the reduction of cut-and-carry use after World War II has been reported in individual areas. Amidst such changes, the multidimensional value of secondary grassland tends to decline. Constructi … More on of a secondary grassland conservation system that involves various agents including residents of the surroundings and visitors is needed.Thus, this research clarified (1)the establishment and transformation of a maintenance and management system for secondary grassland in terms of periods of cut-and-carry use targeting the Kirigamine district and it predicted future forestation based on spatial patterns of the decrease in secondary grassland. (2)modern values and their interaction and assessed secondary grassland with a focus on the values of visitors in particular. (3)methods of constructing future secondary grassland conservation systems, which is where its originality lies.First, vegetation in secondary grasslands and landscapes are currently have been in decline until now, and maintaining them requires intentional burning and large-scale handling of assorted trees.When obtaining the understanding and cooperation of visitors, use of conservation techniques consistent with a wide ranged of values centering on ecological value will be a perquisite to enhancing assessment. Maintaining open spaces with numerous flowering plants as a result of such management is critical. Management systems for cutting-and-carrying eras serve to conserve landscape and vegetation, and these systems should serve as a reference for alternative strategies even when constructing current systems.

次生草原被认为是日本国家生物多样性战略的重要组成部分。此外，次生草地具有独特的景观，是自然公园景观的重要组成部分。此外，次生草原还具有文化价值等多维价值。在目标区Yatsugatake Chushin Heights准国家公园的Kirigamine区，共有2300公顷次生草原遗存。就生物多样性的保护而言，这一地区是一个重要的地区，作为一种非常有价值的区域景观，适合于像HEmerocallis midendorffii var.这样的植被。次生草原通过砍伐和搬运植被和故意焚烧来维持，但据报道，随着第二次世界大战后砍伐和运输用途的减少，次生草原有转为林地的趋势。在这些变化中，次生草地的多维价值呈下降趋势。构建…因此，本研究明确了(1)以基里加明区为目标的次生草地养护管理体系的建立和变革，并根据次生草地减少的空间格局对未来的造林进行了预测。(2)现代价值及其相互作用，并对次生草原进行了评估，特别是对游客的价值进行了评估。(3)构建未来次生草原保护系统的方法，这是其创新之处。首先，次生草原和景观中的植被目前一直在下降，维护它们需要刻意焚烧和大规模处理各种树木。当获得游客的理解和合作时，以生态价值为中心的广泛价值一致的保护技术将是加强评估的先决条件。通过这样的管理，保持开花植物众多的开放空间是至关重要的。采伐和搬运时代的管理系统有助于保护景观和植被，即使在建设现有系统时，这些系统也应作为替代战略的参考。较少
