Abstract
Taiwan is located in the East Asia Monsoon
Climatic Zone. 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.
