本研究的目的是评估鸟类多样性（丰富度，丰度和社区组成）在三种类型的人工湿地（稻田，鲤鱼养殖池塘，农田池塘灌溉），同时考虑鸟类栖息地组和季节，并揭示湿地的环境特征（如湿地类型，水深，植被覆盖）与鸟类丰富度和丰度。鸟类和环境特征进行了调查，在30个网站（10个网站每个湿地类型）在日本中部的丘陵农业区，考虑四个鸟类群体（开放的土地，湿地，灌木，林地）和三个季节（繁殖，迁徙，越冬）。除灌木和林地物种外，各类群鸟类的丰富度均以养殖池塘最高，其次是鲤鱼塘，最后是稻田。在越冬季节（以及在迁徙季节），农田池塘中的开阔地、林地和总物种的丰度水平显著高于稻田和鲤鱼池塘。湿地类型、湿地面积、水面植被覆盖度和河岸坡度对鸟类种类和数量的影响在不同鸟类类群间存在差异。不同湿地类型的群落组成无明显差异，但季节间差异显著。因此，在丘陵农业区的鸟类多样性保护中，（1）创造时空异质性环境的各种湿地类型是重要的，（2）保护池塘而不是稻田是有效的，（3）应为水鸟考虑更陡峭的斜坡和更丰富的水面植被覆盖。
The aim of the present study was to evaluate bird diversity (richness, abundance, and community composition) in three types of artificial wetlands (rice paddies, carp aquaculture ponds, and farm ponds for irrigation) while considering bird habitat groups and seasons and to reveal the environmental characteristics of wetlands (e.g. wetland type, water depth, and vegetation cover) associated with bird richness and abundance. Bird and environmental characteristics were surveyed in 30 sites (10 sites per wetland type) in the hilly agricultural area of central Japan, considering four bird groups (open-land, wetland, bush, and woodland) and three seasons (breeding, migrating, and wintering). Bird richness of each group was the highest in farm ponds, followed by carp ponds and then rice paddies, throughout the year, except for bush and woodland species. Abundance levels of open-land, woodland, and total species were significantly higher in farm ponds than in rice paddies and carp ponds in the wintering season (and also in migrating season for open-land species). Effects of wetland type, wetland area, vegetation cover on water surface, and slope of bank to bird species and abundance differed among bird groups. There were no differences in community compositions among wetland types, although significant differences were apparent among seasons. Therefore, for bird diversity conservation in hilly agricultural areas, (1) various wetland types creating a spatial–temporal heterogeneity of environments is important, (2) preserving ponds rather than rice paddies would be effective, and (3) steeper slopes and richer vegetation cover on water surfaces should be considered for waterbirds.
