After extensively surveying the natural Chinese fir mixed forests in several mature reserves in our province, further comparative studies have been made on nutrient returns of six major Chinese fir associated species in Wuyi Moutains.

This paper studied the growth law of 28-year-old Phoebe bournei with Cunninghamia lanceolata association at early stage, the results showed height,dbh,volume growth of Phoebe bournei with Cunninghamia lanceolata association at early stage were higher than those of Phoebe bournei pure forest,the 28-year-old single-tree volume reached 0.

Application of Apriori algorithm to selection of Chinese fir′s associated tree species;

Selection and allocation of associated tree species for Loblolly pine plantation in hillock areas of Southern Anhui Province;

Spatial distribution pattern of Chinese fir and its associated tree species in Mount Hutuo;

In this paper,the percentages of importance value of castanopsis carlesii and its associated species are regarded as the measure of the competitive parameter,and the dominant degree of normal stands are regarded as their environmental capacity.

The percentages of importance value of Phoebe bournei and its associated species were regarded as the measure of the competitive parameter ,and the dominant degree of normal stands were regarded as their environmental capacity.

This paper deals with the selection of optimal accompanying tree species for Chinese fir from 61 potential mixed tree species in the natural mixed stands which are habitat in four kinds of groups of site type by means of Fuzzy cluster according to ecological species group s theory.

Set pair analysis is a systematic analysis method, which makes study on same different opposite quantity analysis In this paper, the method is applied for the selection of associated tree species The conclusion from the example shows the method suits for practical productio
