Larix gmelinii is the main forest tree species in Tahe Forestry Bureau. Understanding the relationship between natural larch growth and site conditions is beneficial to scientific forest management. In 1986, a survey of forest specialties conducted by 83 grade students of forestry and some graduate students and teachers in the forestry department of Northeast Forestry University in the summer of 1986 analyzed the issue. 1. Site factors affecting forest growth affect the abiotic factors of tree growth, light and temperature have great changes with time and space, macroscopically and terrain conditions are closely related to the topography to some extent, can reflect the light and temperature Change, even moisture
