Studies on Conservation and Management of Urban and Rural Green Areas for Ground Cursorial Species

本研究旨在分析生物多样性保护绿地结构与地上草本植物栖息地之间的关系，提出与自然环境相适应的绿色管理技术理论和规划。主要研究结果如下：1.研究了塔玛山西南亚托景观的小型啮齿动物区系与土地利用的关系。因此，为了有效地保护啮齿动物的多样性和栖息地，维持YYTO的多种土地利用模式是必要的。2.在草地急剧减少的城市地区，调查了微小田鼠的分布和栖息地偏好。研究表明，湿地植物和农业环境对保护黄鼠等小型动物具有重要意义。并利用微小林蛙的分布、植被和地理信息，编制了调查区微小林蛙的栖息地潜力图，为保护微小林蛙和景观结构提供了依据。3.调查了不同堤防类型的小林蛙的栖息地密度，以阐明平地稻田堤防的生态意义。因此，青蛙对附着在土壤水道上的堤坝有一种亲和力。当它从裸露的土壤变成混凝土时，这个数字变得更小了。有人认为，集聚的乡村聚落可以作为几个物种的栖息地。此外，还对丘陵山区石质梯田的植被和小型动物区系的变化进行了调查。植被演替取决于地貌和管理实践，植被和土壤水分是决定小型动物区系的重要因素。

This study aimed to analysis the relationship between the habitation of ground cursorial species and structure of green area for conservation of biodiversity and presentation of technical theory and planning of green management with natural environment. The results are as follows :1.The relationship between the fauna of small rodents and land use of yato landscape in the southwest Tama hills were studied. We concluded that maintaining several land-use patterns of yato is necessary to effectively conserve the rodents' diversity and habitats.2.The distribution and habitat preference of M.minutus was investigated in the urban area where the grassland was dwindling drastically. It was suggested that it is important, for the conservation of small animals such as M.minutus, to maintain yato landscape with wetland plants and agricultural environment. And it carried out the developing a habitat potential map of M.minutus in the survey area using the distribution of M.minutus, vegetation and geographical information for conserving M.minutus and landscape structure.3.The habitat density of the frog, Rana porsa porsa on each levee type was investigated in order to clarify ecological significance of the levees in flatland paddy fields. As a result the frogs have an affinity to the levees attached to the earth waterways. The number becomes smaller when it was altered to concrete from the naked soil. It was suggested that agglomerated rural settlements functioned as habitat patches for several species. In addition, the changes in vegetation and small animal fauna were investigated in terraced paddy with stone masonry in the hilly and mountainous areas. It was clarified that the vegetation succession is dependent on both land-form and management practice, and that vegetation and soil moisture are important factors in determining small animal fauna
