| 中文摘要: |
| 根据1988年、2000年和2004年3期TM/ETM+遥感影像数据,利用遥感和地理信息系统技术,选取土地利用变化幅度、单一土地利用动态度和综合土地利用动态度指数模型,并应用马尔柯夫模型对宝鸡市金渭两区土地利用动态变化及变化趋势进行了分析。结果表明:16 a来宝鸡市金渭两区耕地面积迅速减少,园地面积迅速增加,同时城乡用地也有较大幅度的增加,林地呈现减少趋势,而未利用地有增加趋势,水域面积变化不大。未来16 a内该区域的土地利用变化基本趋势是:园地和城乡用地将持续增加,城乡用地增加速度较快,林地将持续减少,耕地、水域和未利用地变化不大。 |

| Dynamic change of land use and its tendency in Jintai and Weibin districts of Baoji city were analyzed based on translated data from TM/ETM+ remote images in 1988, 2000 and 2004.Using the spatial analysis techniques supported by RS and GIS, the models were chosen to analyze the dynamic change characteristics and tendency of land use, including the change scope and the single dynamic degree and the comprehensive dynamic degree of LUCC and the Markov prediction respectively.The results showed that the cultivated land decreased dramatically, the garden land increased dramatically, the urban area and rural construction area grew with a relatively high speed, the forestry area showed a tendency of decrease, the unused land area showed a tendency of increase, and the water area changed little in the 16 years between 1988 and 2004.The change tendency during sixteen years between 2004 and 2020 indicated that the garden land and the urban and rural construction land were still increasing, and the urban and rural land increased with a high speed, the forest land were still largely decreasing, and the cultivated land, water land and unused land area changed little. |
