The rapid expansion of construction land is one of the main characteristics of modern land use change in China. Based on the land use database acquired by interpreting the multiple-temporal Land sat Thematic Mapper (TM) images (1995, 2000 and 2005), spatial overlay analysis, spatial-clustering analysis and buffer analysis of GIS were applied and ESI (expansion speed index) and EII (expansion intensity...
A novel velocity compensation algorithm is proposed. By extracting all potential scatters of two range profiles as two point patterns, the algorithm matches the point patterns by means of graph matching method. The velocity is estimated by the distance of correspondent points. The simulation experiments on range profiles with varying SNR, false scatters, and clutter aiguilles show the robustness of...
The estimation and distribution of the vegetation biomass in submerged area of Angu Reservoir, Sichuan Province, based on CBERS data acquired in 2006 was researched. In order to select the optimum image characteristic data, correlative analysis were calculated among the biomass field sampling data, CBERS band 1- band 4 data and the NDVI data. The results show that field sampling data is best relative...
The subsided land of mining area is not only the land and ecological environment damage caused by the exploit of mineral resources but the very important land resource to sustainable development of the resource-based cities. A view is put forward that the ecological reconstruction of collapsed land of the resource-based cities should be planed based on its zones. Taken the Pingdingshan City as a case,...
The complete nucleotide sequence of a large (67kb) cryptic plasmid pBMB67 from Bacillus thuringiensis strain YBT-1520 was determined. Of the 74 predicted open reading frames (ORFs), 25 (34%) were assigned putative functions, 18 (24%) encoded conserved hypothetical proteins, and 31 (42%) had no homology to any genes present in the current open databases. The ORFs with similar functions were organized...
