Research on the forest edge illumination of Larix principis-rupprechtii plantation
The forest light environment is the foundation for stands updates . This paper introduced the 30 m transect method to compare the stand inside the forest edge variation of illumination of Larix principis‐rupprechtii plantation .The results showed Larix principis‐rupprechtii edge relative light intensity decreased with increasing distance from the forest edge and then remained stabilizing .When at density of 630 /hm2 ,there was less obvious for‐est edge distance variety ,with significant quadratic polynomial relationships between relative light intensity and stand edge . Relative light intensity can better reflect the stand edge effect .With the increase of forest stand density the light intensity decreases gradurally ,and the relative light intensity and stand density showed a significant power function correlation .
