Effects of Chinese-fir mixing with N-fixing and non-N fixing tree species on forestland quality and forest-floor solution chemistry
杉木与固氮和非固氮树种混交对林地土壤质量和土壤水化学的影响

Chinese fir (Cunningharnia lanceolata), a type of subtropical fast-growing conifer tree, widely distributed in South China, and its plantation area in China is more than 7×10~6 hm~2, accounting for 24% of total area of planted forest in China. In recent decades, the system of successive plantation of Chinese fir is widely used in the southern china for an anticipated high economic return. However, recent studies have documented that the practice of this system led to dramatic decreases in soil fertility and...
