摘要
Due to the spatial heterogeneity of forest soil,it is a difficult problem to evaluate the forest soil fertility on a large scale.This study conducted a grid survey of forest soil in Yunfu City,Guangdong Province,and used the the gray correlation system to evaluate forest soil fertility in each county.The results showed that the effect of using the gray correlation analysis to evaluate soil fertility in Yunfu city was ideal,and the fertilizer strength in each county was in order of Yunan,Yun'an,Yuncheng,Xinxing,and Luoding.The results can provide an appropriate scientific basis for forestry division within the county scale.
