碩士 / 國立彰化師範大學 / 地理學系 / 100 / Migration "stopovers" provide a crucial link between wintering and breeding areas for migratory birds. Food obtained at stopovers provides energy for continued
migratory flight and nutritional reserves that may be essential for successful reproduction upon arrival at the breeding grounds. Shorebirds and other migratory species that depend on natural wetland stopovers are being challenged by a rapidly changing landscape. As the natural wetlands diminish, researchers studying waterbirds in rice fields are becoming another habitat for waterbirds to use.Rice field landscapes often consist of various land uses and land cover, including rice fields, fallow water fields, irrigation ditches, other agricultural fields, grasslands and natural wetlands.Numerous studies indicate that local management practices, such as water depth, type of flooding and seasonal difference of plant type, can influence waterbird composing, amount and the way of using rice field. However, the effects of size, distribution of rice fields and associated habitats at a landscape scale have received less attention.
A case study is presented for research the rice field landscape change and structures that affect the use of waterbird at migration season in seafront Taoyuan. The result shows that habitat connectivity, area of rice and others type of fields, and presence and distance can be
important parameters influencing bird use of fice fields.
