- Abstract:
-
To reveal the characteristics and formation mechanism of land use pattern change in the process of urbanization in Songhuajiang Basin, and provide decision-making reference for regional land use allocation and management, land use transfer matrix, land-use information mapping, standard deviation ellipse analysis, geographic detector were used to analyze the land use change and formation mechanism in the study area from 1996 to 2016. The results showed that: (1) land cover was dominated by cultivated land, accounting for more than 59% of the total area, followed by forestland and construction land, and the change feature was farmland conversion; (2) land-use mapping showed the northwest-southeast pattern, the stable type was the main form, and the distribution was most concentrated, and the distribution of later change type, repeated change type, continuous change type was more scattered, and mainly focused on zones alone the banks of Songhuajiang River and Hulan River in the period 1996—2016; (3) the influences of elevation and annual mean temperature and etc. of natural factors on land use pattern change were always greater in the period 1996—2016, and the impact of each factor on land use pattern changes was stronger in the period 1996—2006; (4) the main controlling factors of land use change in different periods were different, the change of cultivated land was greatly influenced by height and annual average temperature, and the change of construction land was greatly influenced by the distance from water. Land use change had obvious differentiation characteristics which were influenced by natural, social and distance factors, and planning and management of land use at low elevation and nearby water should be strengthened in the study area in the future.
