首发时间:2019-09-06
Abstract:In order to study the land use change situation of Qingdao in recent 10 years, this paper used the land Use classification system of China\'s coastal zone to overlay the land use of 2015 by visual interpretation with 2005 data in Arcgis10.2. The results showed that the residence of Qingdao increased 1612.3km2, the area of urban mining increased 351.2km2, the area of woodland increased 499.7km2, and the area of arable land decreased 1911.9km2, the grassland areas decreased 342.4km2, and the water body decreased 277.4km2. These changes were mainly due to the speed of urbanization, another reason was that the Government attached importance to environmental issues, vigorously carried out afforestation and returned farmland to forest. The research provided scientific basis for local government departments to formulate targeted land use planning and policies, which is of great practical significance for regional comprehensive, coordinated and sustainable development.

基于ARCGIS下的青岛市2005~2015年土地利用动态变化分析研究
摘要:为了研究青岛市近10年来的土地利用变化态势,本文采用中国海岸带土地利用分类系统,将目视解译的2015年青岛市土地利用数据与2005年青岛市土地利用数据在Arcgis10.2中进行叠加。结果表明: 青岛市的居住地增加了1612.3㎞2,城镇工矿用地面积增加351.2㎞2,林地面积增加499.7㎞2;耕地面积则减少了1911.9㎞2,草地面积减少了342.4㎞2,水体减少了277.4㎞2。这些变化主要由于城镇化速度加快,其他原因是政府重视环保问题,大力开展植树造林与退耕还林。此研究为当地政府部门制定有针对性的土地利用规划与政策提供科学依据,对于区域全面、协调与可持续发展具有重要的现实意义。
