Land use conversion is the hottest issue in the research field of globe changing. The Coastal Area of the Pearl River Estuary where the zone has a typical feature of land use change and significant ecological effects is selected as a case. Applying the satellite images of Landsat-TM and the integrating techniques of RS and GIS, the present study analyzed the temporal and spatial processes and gravity...
For the first time, we propose and demonstrate a novel parallel and Interlaced bandwidth allocation scheme in all-optical sub-banding WDM-OFDM PON system. By simulation, we successfully realize three dimensional resource allocation flexibly among optical network Unites (ONUs).
Land use change was the most significant aspect in the research field of globe changing. Affected by both of natural and artificial factors, the land use and land resources quality varied continually. Zhongshan City where the zone had a typical feature of land use change and significant ecological effects was selected as a case. Applying the satellite images of Landsat-TM and the integrating techniques...
On-line monitoring system attempted to combine the GPS and GIS technology, used spatial information technology to manage sources of spatial information and the business. GIS technology had been effective application in the management of pollution sources, and promoted deep reform of the on-line monitoring management reform. The on-line monitoring system in Panyu District of Guangzhou would make department...
