10、1胸径树木根颈以上1.3米处，相当于一般人胸高位置的树干直径。树木胸径一般指带皮直径，计算胸径以厘米为单位，用围尺测定，它标志立木粗度和计算立木材积的主要依据。3.2树高单株立木从根颈至树梢顶端的高度。常以h表示，以米为单位。利用各种类型的测高器或目测方法测定，是计算单株立木材积和林分平均高的主要依据。3.3立木材积树木各部分（包括树干、树枝、树根及树皮）和各种木材（包括原条、原木、板方材等）的体积叫材积。（立木的体积就是立木材积）是林业主产品的重要数量指标。常以V表示，以立方米为计量单位。树木材积常指带皮材积，根据存在形式和调查要求，选择适当材积公式或立木材积表测算，保留4位小数。3.4二元
11、立木材积表以林木胸径、树高为自变量，立木材积为因变量建立的函数关系。3.5建模单元具有地域的连接性和行政区的完整性以及自然条件的一致性的区域组合。3.6树种（组）具有相同或相近生物学特性的树种组合。DB21/T 4374202523.7林分形高林分形高是单位面积林分蓄积与其相应的胸高总断面积的比值。4地域、树种组的确定4.1地域的确定4.1.1辽宁东部地区包括丹东，抚顺，本溪三个市；鞍山市的岫岩及铁岭市的西丰县、开原市、铁岭县三县（市）。4.1.2辽宁西部地区包括锦州、葫芦岛、阜新、朝阳、沈阳五市及铁岭市的昌图县。4.1.3辽宁南部地区包括大连、鞍山（除岫岩县）、营口、盘锦、辽阳五市。4.2树
