一般来说。胸径、树高、胸高断面积等冠层结构参数都可以作为评价立地质量的

Generally speaking. Diameter, height, basal area of ​​the canopy structure parameters and the like can be used as site quality evaluation index, but because a high stand density and trees Thinning less affected, and the data is easy to measure, so the actual work in the use of high trees Making of table-level index to evaluate site quality.

Generally speaking. The canopy structure parameters such as chest diameter, tree height and chest height break area can all be used as indicators to evaluate the quality of standing land, but because tree height is less affected by forest density and intercutting measures, and the data are easy to measure, so in practice, more tree height preparation status index table is used to evaluate the quality of standing.

Generally speaking. The canopy structure parameters such as DBH, tree height and cross-sectional area of DBH can be used to evaluate the site quality. However, because the tree height is less affected by the stand density and thinning measures, and the data is easy to measure, the site quality is evaluated by the site index table compiled by tree height in practical work.<br>
