备注

土地资源是人类生存发展的基本资源,海岸带是人类活动密集区。为探究经济发展背景下土地利用变化状况,给予国土空间规划提供适当的理论支撑,运用图谱分析、强度分析、交叉列联表等方法研究1989—2019年莱州湾南岸海岸带土地利用结构变化、地类转化以及演变稳定性。结果表明:(1)土地利用结构时空变化方面,莱州湾海岸带地类以盐田养殖池、耕地、建设用地为主,1989—2019年耕地和滩涂面积减少最多,建设用地和盐田养殖池扩张面积最大。(2)地类转化方面,1989—2009年建设用地转入面积最大,2009—2019年耕地涨势最强。(3)土地利用演变稳定性方面,除滩涂和盐田养殖池外,其余地类面积的增长均表现为稳定性; 除盐田养殖池和水库坑塘外,其余地类面积的减少均表现出稳定性。结果表明不同地类的转换和空间分布存在明显差异,自然因素和人类土地利用行为会对土地利用时空演变过程和稳定性产生重要影响。
Land resource is an important foundation for human life. Coastal zone is one of the most concentrated and active areas for human activities. In order to explore the status of land use change in the context of economic development, we provided appropriate theoretical support for spatial planning. The changes of land use structure, the land class transformation and the stability of land use evolution of the south coast of Laizhou Bay from 1989 to 2019 were studied by using geographic information map, intensity analysis methods and confusion table. The results indicated that:(1)in terms of temporal and spatial changes in land use structure, the land types in coastal zone of Laizhou Bay were mainly salt farming ponds, cultivated land and construction land; from 1989 to 2019, the area of cultivated land and tidal flats had decreased the most, at the same time, the areas of construction land and salt farming ponds had increased the most;(2)in terms of the land type transformation, from 1989 to 2009, the area of construction land had increased the most, at the same time, the most obvious change was the decrease of cultivated land from 2009 to 2019;(3)in terms of the stability of land use evolution, the increase of other land types showed stability except for tidal flat and salt pond; the decrease of other land types showed stability except for salt pond and reservoirs. There were obvious differences in the conversion and spatial distribution of different land types in the coastal zone of the south coast of Laizhou Bay. Natural factors and human land use behaviors will play a significant role in the processes and patterns of land use change.
