通过测定标准地的海拔、坡向、坡度和坡位;利用角规进行林木调查;用标准地号、层次、盖度、平均高度、生长状况、分布状况等进行幼树、下木、活地被调查;观察记录层外植物种类名称、盖度、高度、生长方式和分布状况,调查百花山林场主要森林类型的分布及林分结构特点。通过分析可以得出百花山自然保护区植物有明显的垂直带谱。海拔和坡向是制约群落分布的主要因子,两者的共同影响主要表现在温度、光照、水分生态因子方面,土壤和人为因素也在客观上制约着森林群落的分布与状态。林分层次之间乔木层、灌木层和草本层之间也相互影响制约着群落的发展。

The elevation, ascent passed a measurement standard to, slope and ascent;Make use of the Cape rules carry on wood to investigate;Use standard number, layer, cover degree, average height, growth condition, distribute condition's etc. to carry on young tree, descend a wood and live ground drive investigate;Plant category name outside the layer of the observation record, cover degree, height, growth way with distribute condition, investigate all flowers forest field distribute of main forest type and Lin2 Fen structure characteristics.Pass analysis can get the all flowers mountain nature reserve area plant have obvious of perpendicular take table.Elevation and ascent to is the main factor that the check and supervisions fall to distribute, both of common the influence be main performance in the temperature, light shine on, the factor, soil and artificial of the humidity ecosystem factor also at objective top check and supervision wear the forests fall of distribute and appearance.W
