摘要：How soil nutrition availability affects the density, height, and ground diameter of seedling of Dacrydium pierrei Hickel was investigated in three selected National Nature Reserve of China using mixed model approaches. Results showed that the soil nutrient content in the studied area was significantly different; the relationship between six nutrient elements and the density, height, and ground diameter of seedling were almost in exponent and logarithm; ground diameter is the best seedling growth factors for modeling by soil nutrition availability; models ((14)-(16)) are the best models for simulating the relationship between them; D. pierrei seedlings growth has a specific distribution range in altitude, latitude, and longitude. It was observed that increasing soil fertility, cleaning litter under the forest appropriately, healthy seeds obtainment, artificial cultivation and breeding seedlings may take protective and management measures for D. pierrei.
