Paper Title:
Analysis of Soil Nutrient Content Characteristic for Inductive Transformed Low-Quality Forest in Greater Higgnan Mountains
  Abstract

In This paper, the miscellaneous tree low-quality forest and Oak low-quality forest in the Greater Hinggan Mountains region were transformed inductively by planting Siberian Korean pine, Mongolica, and Larch, respectively. With the method of using different bandwidth and gap area, the soil nutrient characteristics were changed. The results indicated that the pH of soil increased slightly by different ways of induced transformation, but the variance was not significant (P﹤0.05). After reforming the induced soil organic matter content was balanced, while the basic content of hydrolysable nitrogen increased, and the availiable phosphorus decreased. Soil rapidly-available potassium content in Oak coppice was reduced but raised in the region of secondary performed miscellaneous wood. The variation coefficient of Siberia Korean pine was the largest with different soil pH value of various bandwidth and soil nutrient content (except for availiable phosphorus). Content of soil organic matter and hydrolysis nitrogen, phosphorus and potassium content are significantly positive correlated. At the same time, clear-cutting bandwidth and soil organic matter and hydrolysis nitrogen content are significantly negative correlated. During the transformation of forest gap in the sunny and shady slope, smaller area of forest gap owed the larger soil nutrient content. Generally, soil nutrient content in sunny slope is higher than the shady one.
