| Abstract: | Forest canopy closure,which is an important forest inventory factor,plays an important role in forest management and ecosystem management.But surveying and application of canopy closure are restricted because of obscure concept and imperfectness of measuring method.This paper discusses the connotation of canopy closure,puts forward vertical canopy closure and point canopy closure,systemically summarizes the measuring method and instrument of canopy closure at home and abroad,in order to provide rational application and accurate measurement of canopy closure in forestry production and research. |
| Keywords: | forest canopy closure measuring method |
