Designation & Zonation of Slopeland
* Designation & Zonation of Slopeland

     Taiwan is an island with many mountains, and three-fourths of its land area is slopeland. Much of this land has steep gradient and fragile geological formation. Rivers are short and flow rapidly. Average annual rainfall is 2,500mm, and Central Weather Bureau statistics show that Taiwan is hit by an average of 3.2 typhoons every year. These typhoons usually occur between July and October, and 70% to 90% of annual rainfall in concentrated in heavy rainfalls directly related to typhoons. These torrential rains often cause landslides, debris-flow and other natural disasters by movement of rock and soil. These incidents cause destruction to life, property and infrastructure.


     Slopeland scope refers to a state-owned forestry zone, forest land for experiments, protected forest areas, as well as public and private land that is 100m above sea level, or is less than that but has an average gradient of 5% above, as designated by the Central Government and the authorities concerned in municipal governments accoring to natural terrain features, administrative areas, or the requirements of conservation or other land utilization. Usage designation for slopeland is regulated under Article 6 of Regulations Governing Conservation and Use of Slopeland into the following categories: farm and pasture land, forestry land, and conservation land. Owners or users of the land may not exceed the limits of land capacity.
