Characteristics of Land Use Changes in Nansha District,Guangzhou Based on GF-1 Remote Sensing Images
Published 2023-01-01“…The type of land use can reflect regional economic,social,and ecological benefits.In order to gain a deeper understanding of the composition and changes of land use in Nansha District,this paper selected the GF-1 PMS data in 2016,2017,and 2022 for preprocessing and used support vector machine algorithm oriented to supervised classification for remote sensing image interpretation.According to the results of field investigation and correction,the overall accuracy of the corrected land-use products was above 90%,and the Kappa coefficient was above 0.85.The land use transfer matrix in Nansha District from 2017 to 2021 was constructed,and a comparative analysis was carried out in combination with the land use planning in 2025.In 2017,the main land use type in Nansha District was water area,accounting for 40%.By 2021,the impervious surface has increased by 10% (14.39 km<sup>2</sup>),mainly from the transfer of cultivated land (8.06 km<sup>2</sup>) and water area (7.48 km<sup>2</sup>).The water area has decreased by 3% (10.63 km<sup>2</sup>),of which the conversion to impervious surface accounts for 70% of the total reduction area;cultivated land,forests,and grasslands have a small reduction.The urbanization process of Huangge Town and Nansha Street is the fastest,and the impervious surface area has increased significantly.The cultivated land in Dongchong Town and Dagang Town has been reduced on a small scale.A large amount of water areas in Wanqingsha Town and Longxue Street have been invaded by impervious surfaces.Compared with the overall urban planning of Nansha District in 2025,except for Zhujiang Street and Wanqingsha Town,the construction of the underlying surface of other towns and streets in Nansha District is basically completed.At the same time,the proportion of water areas,forests,and grasslands in Nansha District that are encroached by impervious surfaces is relatively high.In order to avoid damage to the ecological environment,it is necessary to strike a balance between social and economic development and ecological environment protection.…”

According to the values of the Environmental Quality Standards for Soil (EQSS), the concentrations of heavy metals have not exceeded the standards and have relatively low potential ecological risks. (2) In terms of health risks, all soil heavy metals basically do not bring non-carcinogenic risks but acceptable carcinogenic risks to adults and children, except for Cd. …”
