为了寻求一种减少样地每木检尺的测树方法,我队在云南省临沦地区进行森林资源清查的同时,选定206.2公顷林地进行了全林检尺和分层抽样调查。在此实测区内对分层抽样样点进行角规、三株木、六株木等测树方法试验。初步总结如下:一、概况实测区西南坡向,平均坡度20度,海拔1,100米。有林地面积占82.2%,皆为云南松林。
In order to find a method to reduce the tree-measuring method of every plot, our team selected 206.2 hectares of forest land for the survey and stratified sampling survey of forest resources while forest resources inventory was conducted in the area of Linxian, Yunnan Province. In this survey area, the sampling points of stratified sampling were tested by angle measurement, three trees and six trees. Preliminary summary is as follows: First, the survey area southwest slope, the average gradient of 20 degrees, 1,100 meters above sea level. Forest area accounted for 82.2%, all of Yunnan pine forest.
