The Correlation between Forest Productivity and Site Condition -- A Case Study of Forest Productivity of Pinus massoniana and Eucalypt in Ningming County
摘要
Abstract
Taking the forest productivity of Pinus massoniana and Eucalypt in Ningming county of Guangxi for example, based on the biomass of forests calculated by the method of biomass continuous function to reckon the productivity of sample plots, using high accuracy Digital Elevation Model （DEM） （1 ： 10 000） to calculate slope aspect, slope degree and elevation of research areas and the To- pographic Position Index （TPI） to estimate slope position and landform type, the correlation between different forest species＇ productivity and site condition was studied by using P （Probability） value in- spection. The results showed that correlation between site condition and productivity of Pinus massoniaria and Eucalypt was remarkable, which was various among different forest species. Site conditions of elevation, slope position and soil type played restricted role in productivity of Pinus massoniana and Eucalypt. The effect of landform type and thickness of soil on Pinus massoniana was obvious while slope aspect and soil mother rock were correlative to Eucalypt. The effect of slope degree on Pinus massoniana and Eucalypt was less. So the correlation between forest productivity and site condition depended on forest species. This research would provide theory basis for establishing calculation model of forest productivity correctly and planning the layout plan of planting species reasonably.关键词
