Soil Quality in Different Forest Plantations in Siming Mountainous Area of Zhejiang Province

In April, 2020, soil samples were collected from plantations of Phyllostachys edulis, Pinus taiwanensis, Liriodendron chinense, Cerasus lannesiana, Acer palmatum ‘Atropurpureum’ + C. lannesiana and ecological restoration in Siming mountainous area, Yuyao city of Zhejiang province. Determinations were conducted on soil physico-chemical properties and enzyme activities. Principal component analysis was used to evaluate soil quality of different plantations. The result demonstrated that there were no significant difference of soil bulk density, field capacity, total porosity, pH, cation exchange capacity, total nitrogen content, total phosphorus content, total potassium content among different plantations. Soil available nitrogen and phosphorus content increased obviously, but soil organic matter and enzyme activities decreased significantly in plantation of C. lannesiana and A. palmatum ‘Atropurpureum’ + C. lannesiana (P<0.05). Soil quality of six plantations was comprehensively evaluated and was ordered by P. taiwanensis >Ph. edulis>L. chinense > C. lannesiana >ecological restoration>A. palmatum ‘Atropurpureum’ + C. lannesiana.
