一九七二年我队在本地区库伦斯区的绰纳河流域进行森林资源调查时,发现几块十八年前的标准地。这是原林业部综合调查队远在一九五四年进行调查时设置的。实际上,这些已起到了固定标准地的作用,它们真实地记录了十八年来樟子松林生长发育情况,是十分难得的。营林组根据三块标准地复查记录和几年来的其它调查材料写成本文,有相当的参考价值。发现这几块十八年前的标准地,对我们也有很大启示。如果有条件的林区适当设置一些固定标准地,定期复查,其价值将是非常大的。
In 1972, when we conducted a forest resource survey in the Chiron basin in the Culum region of the region, we found a few standards that were 18 years ago. This was set when the former comprehensive investigation team of the Forestry Department investigated in 1954. In fact, these have played a fixed role in the standard, they truly recorded 18 years of Pinus sylvestris growth and development, is very rare. Yinglin group according to three standard records and review of the past few years to write down the text of the investigation, a considerable reference value. The discovery of these standards of eighteen years ago also gave us a great inspiration. If the conditions for the establishment of a number of forest areas properly fixed, regular review, its value will be very large.
