For purposes of this Act, the following special terms or phrases are defined as below:
1.Soil and water conservation treatment and maintenance: the application of engineering, agronomic or vegetative measures to protect soil and water resources, maintain natural ecology and landscape, and prevent erosion, landslide, debris flow, and other disasters.
2.Soil and water conservation plan: a plan on soil and water conservation treatment and maintenance.
3.Slopeland: state-owned forestry area, forest land for experimentation, protection forest land and public and private land conforming to either of the following which the central or special municipality regulatory authority identifies in accordance with the natural terrain, requirements of the administrative regions, and requirement for conservation and utilization, and which are approved and publicly announced by the Executive Yuan upon application of the central or municipal competent authority:
(1)with an elevation of 100 meter or above; or
(2)with an elevation below 100 meter but average slope 5% or more.
4.Watershed: area above a given point of stream and river where the natural flow of water converges.
5.Designated soil and water conservation area: area designated by the central or special municipality regulatory authority where soil and water conservation treatment and maintenance must be strengthened.
6.Reservoir watershed : area within the watershed of a reservoir or dam (including the outlet of an off-channel reservoir).
7.Protection belt: land not suitable for farming within a designated soil and water conservation area which shall be afforested with legally prescribed tree species or in which natural forest growth or vegetation cover shall be maintained.
