萤火虫栖息地估计使用地理信息系统（GIS）和水文模拟在名取河流域，日本东北部。为探讨萤火虫栖息地的适宜条件，确定了萤火虫栖息地与地质条件、水文条件、土地利用类型等物理环境之间的关系。萤火虫栖息地的适宜性标准，然后定义栖息地适宜性指数（HSI）估计的基础上。我们发现，流域面积小于5000米（2）与平坦的平原（坡度小于0.15）是理想的萤火虫栖息地的地质条件。此外，我们发现，非城市化地区的城市比小于0.1，落叶林，农业用地和稻田是萤火虫栖息地的最佳土地利用类型。该评估还表明，萤火虫更喜欢生活在浅水和平静的水域环境中（水深小于500 mm，流速小于1.0 m/s）。通过比较萤火虫栖息地的实地观察，这些标准确定的栖息地位置进行了验证。结果表明，该模型是成功的估计萤火虫栖息地在水环境中的存在。(C)2007 Elsevier B.

Firefly habitat was estimated using a geographical information system (GIS) and hydrological simulation in the Natori River basin in Tohoku, Japan. To investigate suitable conditions for firefly habitat, the relationships between observed firefly habitat and physical environment, such as geological conditions, hydrological conditions and land use types obtained from digital maps were determined. Suitability criteria for firefly habitat were then defined based on habitat suitability index (HSI) estimation. We found that watershed areas smaller than 5000 m(2) with flat plains (slopes less than 0.15) are ideal geological conditions for firefly habitat. Further, we found that non-urbanized areas with urban ratios less than 0.1, deciduous forests, agricultural lands, and paddy fields are the best land use types for firefly habitat. This evaluation also indicates that fireflies prefer to live in shallow and calm water environments (water depths less than 500 mm and velocity less than 1.0 m/s). The habitat locations determined by these criteria were validated by comparing them to field observations of firefly habitat. The results indicate that this model was successful in estimating the existence of firefly habitat in hydroenvironments. (C) 2007 Elsevier B.V. All rights reserved.
