Values of Native Tree Species in Forest Form Improvement of Xiamen;

Based on the man-made with the secondary community characteristics and the natural conditions in Weiling Park of Shenzhen city, authors make a design for the stand rebuilding reasonably.

After the forest tree improvement in XiQiao Mountain, the physics and chemistry of forest soil which including physical property, chemical property and the microbial content have alterred.
