The plant diversity and soil physicochemical properties of five national roads in XuZhou area,China

摘要

The plant diversity and soil physicochemical properties of five national roads in Xuzhou area were studied with the investigation methods of uniform distribution and typical sample and determination of soil properties in laboratory. The results show as follow:(1) There were 40 kinds of arbor,23 kinds of shrub, 40 kinds of herb in five national roads. P. lasiocarpa, Ligustrum lucidum, Juniperus chinensis cv. Kaizuka, Photinia serrulata and T. repens played important roles, their important values were at the top.(2) The order of comprehensive Shannon-Wiener index was G206 >G104>G311>G310>G205. Artificial trees and shrubs inhibited the growth of weeds to some extent. (3) Soil physicochemical properties were affected by human beings, large soil bulk density, high pH value, nutrient deficiency were a common feature of soil in five national roads.
