Abstract
Notice of Retraction
After careful and considered review of the content of this paper by a duly constituted expert committee, this paper has been found to be in violation of IEEE´s Publication Principles.
We hereby retract the content of this paper. Reasonable effort should be made to remove all past references to this paper.
The presenting author of this paper has the option to appeal this decision by contacting TPII@ieee.org.
Roads encroaching into undeveloped areas generally degrade ecological and watershed conditions. The road networks bring forth many ecological effects. The span of documented effects ranges from a few meters to many kilometers and different grade road have distinct impact. We used a metric, roadless volume (RV), which is derived from the calculated distance to the nearest road to estimate the effect of different roads on various ecosystems and took Xishuangbanna Autonomous Region as a case. The results showed that roads had a close positive relationship with ecosystem patch number, village and negative relationship with elevation. The calculated RV index clearly reveal road effect on different land uses. The grassland, shrub, forest land have more roadless volume while constructive lands have less. Scenario analysis showed RV decreased with with the road network completeness. This suggests that full road network data should be considered to avoid the underestimate of the comprehensive effects.
