Larch is the most widely planted coniferous species in China. The development of larch plantations
is very important to the development of plantations of China. This paper summarized the soil physical
properties，soil chemical properties，biological properties of larch plantations，analyzed the current research
on the soil degradation of larch plantation，and concluded and generated the time，method，type and dosage
and effect of fertilization，in order to provide the scientific references for the sustainable management of larch
plantation as well as for the study of nutrient management and intensive management.
