Study On The Growth Status Of Pinus Massoniana Under Different Site Conditions In The Red Soil Eroded Area

To the problem of serious water and soil erosion of red soil eroded area,the poor growth status of Pinus massoniana, poor soil, low level of ecological benefit, based on the investigation on sample spots through the investigation of different site conditions and relative environmental factors to systematically study the growth law of Pinus massoniana in the research region. With Pinus massoniana for the main object, site factors and soil Physical and Chemical characteristics analyzed, the influence on the growth of Pinus massoniana has been systematically studied in the fixed standard sample spots in Hetian and Sanzhou Bridge, Changting County of Fujian province. The result shows that growth status of Pinus massoniana in the region has great difference by comparison with some other regions. Different site factors have different influence on the growth status of Pinus massoniana, the influence sorting is eroded intensity, slope location, altitude, humus thickness, slope approaches and slope by descending. Soil erosion has close relation with soil fertility, more measure should be made to increase vegetation cover and soil fertility to stimulate the growth of Pinus massoniana during the ecological restoration. According to the research result, the theory basis and relative measure have been put forward on the Pinus massoniana transformation under degeneration in the researsh area.
