摘要: In the study we mapped and analyzed the land use/cover changes in Zheng Lanqi county by visual interpreting the 3 sets of Landsat TM and ETM remotely sensed images received in 1990, 2000 and 2005.The 6 broad types of land use/ cover were interpreted for the study area. Through analyzing land use/cover changes, our study indicated that the grassland and built-up area is dominant landscape in the study area.The grassland in the study area shrank 588.68km(2) for urbanization and farmland cultivation for first periods. The unchanged land is 10639.75km(2) and 10743.18km(2) for the two periods (1990-2000 and 2000-2005), respectively. This indicated that the landscape conversion in second period became stable than that of first period, and environment is improved since 2000.
