土地形式
A LandForm is the class of geographically and/or geologically distinct areas that occur on Earth's surface, including mountains, hills, plains, valleys, deltas, and features of submerged land areas such as the ocean floor.
Relationships      
Parents GeographicArea A geographic location, generally having definite boundaries. Note that this differs from its immediate superclass Region in that a GeographicArea is a three-dimensional Region of the earth. Accordingly, all astronomical objects other than earth and all one-dimensional and two-dimensional Regions are not classed under GeographicArea.
Children 群島An Archipelago is a group of islands.
 盆地A Basin is an area of land enclosed or partially enclosed by higher land.
 孤山A Butte is an Upland raised sharply from the surrounding region. Smaller in area than a Mesa.
 峽谷A Canyon is a narrow valley with steep sides, usually created by erosion.
 披肩A Cape is a piece of land projecting into a body of water.
 洞穴矩陣A CaveMatrix is the framework of earth or rock in which a Cave is embedded.
 三角洲A Delta is a LandForm composed of silt or other alluvium, deposited at or near the mouth of a river or stream as it enters a body of relatively static water. Typically a delta is flat and fan-shaped.
 冰川A Glacier is a large body of slow-moving ice. Glaciers displace soil and rock while moving over land surfaces and break apart, forming Icebergs, when they reach the sea.
 爬坡道A Hill is a raised part of the earth's surface with sloping sides - an old mountain which because of erosion has become shorter and more rounded.
 低地地區A LowlandArea is a land area lower than the surrounding region, and usually level land.
 檯面A Mesa is a land formation having a relatively flat top and steep rock walls.
 A Mountain is a high, rocky LandForm, usually with steep sides and a pointed or rounded top, and higher than a Hill.
 山脈A MountainRange is a row or chain of connected mountains.
 半島A Peninsula is a piece of land that extends into a body of water and is surrounded on three sides by water. Typically connected by an Isthmus or neck of land that is narrower than its main portion (contrast with Cape).
 高原A Plateau is a flat upland area with one steep face, elevated plain.
 A Reef is a ridge of rock, coral, or sand at or near the surface of a WaterArea.
 河岸A RiverBank is the ShoreArea adjacent to a River.
 海岸A Seacoast is the ShoreArea along the margin of an ocean, extending inland approximately 1-3 km from the low water mark.
 淺灘A Shoal is a LandForm near a WaterArea with most of it is covered by a %BodyOfWater.
 傾斜的區域A SlopedArea is a land surface which lies at an angle to the horizontal so that some points on it are higher than others, a slope.
 高地地區An UplandArea is a LandArea elevated above the surrounding terrain.
 A Valley is an area of low-lying land flanked by higher ground. Valleys typically contain a stream or river flowing along the valley floor.
 火山A Volcano in the broadest sense, i.e., a region containing a vent through which magmous and/or pyroclastic materials are passed from the interior of the Earth to its surface (atmospheric or underwater).
