Summary: | Key message
The
Eucalyptus
productivity increase was mainly caused by the increased proportion of newly planted areas for
Eucalyptus
afforestation and the decreasing area of original
Eucalyptus
plantations
.
Eucalyptus
tree is a major fast-growing species in South China. The ecological problems associated with quickly developing
Eucalyptus
plantations have been a focus of extensive debate. In this study, we used spatial analysis and geostatistical methods along with field survey data from four successive National Forest Inventories (NFI's) as well as terrain and meteorological data to analyze dynamics of the
Eucalyptus
plantation distribution in China. The
Eucalyptus
productivity levels were compared among the four inventories by measuring annual mean productivity in permanent sample plots to provide a basic description of
Eucalyptus
plantations. Results showed that the area of
Eucalyptus
plantations increased constantly in China, expanding from 60.7 × 10
4
ha in the 5th inventory to more than 445.5 × 10
4
ha in the 8th inventory. However, these changes did not necessarily indicate an improvement in the management quality of
Eucalyptus
plantations, since they were mainly caused by an increase in the proportion of newly planted
Eucalyptus
areas and the decrease of the original
Eucalyptus
plantation area. The productivity of
Eucalyptus
plantations was significantly positively correlated with temperature and rainfall, but negatively correlated with elevation. |
