Coastal zones in Taiwan are constantly subjected to strong northeastern wind in the winter and destructive typhoons in the summer, as a result, coastal windbreaks are very common in these areas. The existence of a coastal windbreak belt has proven beneficial to crop yields, and effective in preventing the inland migration of coastal sand dunes. Therefore, coastal windbreak is important in sustaining the environmental quality and landuse potential of the coastal zone areas. However, coastal zone development has resulted in environmental changes which in turn influenced the growth and distribution of coastal windbreaks. And the changes of coastal windbreak condition and distribution also have impacts on the quality of coastal landuse activities. This project aims to study the evolution of coastal windbreaks in north Taiwan, the causes of the change, and the effects of the change. The study will proceed in five consecutive years. This first-year study is focused on the historical evolution of the distribution of the coastal windbreak in Tao-Yuan, Taipei and Yi-Lang Counties. By using ARC/INFO geographical information system, significant changes in windbreak distribution in several coastal area were detected through comparisons among 1982, 1988 and 1996 landuse data. These areas include Da-Yuan and Guang-Ying in Tao- Yuan County, Ba-Li and Gong-Liau in Taipei County, as well as Wu-Gia and Su-Au in Yi- Lang County. The authors intend to study the effect of the change of windbreak belts on the landuse pattern around them, and vise versa, further in the future.application/pdf24222 bytesapplication/pdfzh-TW國立臺灣大學地理環境資源學系暨研究所海岸地區防風林環境變遷環境衝擊coastal areawindbreakenvironmental changeenvironmental impactreporthttp://ntur.lib.ntu.edu.tw/bitstream/246246/11360/1/882621Z002015.pdf
