Light pollution, a phenomenon in which artificial nighttime light (NTL) changes the form of brightness and darkness in natural areas such as protected areas (PAs), has become a global concern due to its threat to global biodiversity.
Urban air pollution with PM2.5 as the main pollutant has become increasingly prominent in China since 2010. Scholars have conducted many studies on how urbanization affects PM2.5, but few concerns about the relationship between construction land (CL) …
Rapid urbanisation causes large urban conversions of natural and agricultural land to non-agricultural use. Research on urban expansion has typically disregarded gradient characteristics. The current study uses slope data calculated based on the …
Community is the core spatial unit for evaluating sustainable development. However, single data and method seem inadequate for conducting a scientific, effective, and innovative sustainable evaluation of complex community units. In this study, we …
Along with the rapid development of China’s economy as well as the continuing urbanization, the internal spatial and functional structures of cities within this country are also gradually changing and restructuring. The study of functional region …
针对传统的农作物估产方法过度依赖人工经验,以及实地采样成本高等问题。该研究使用MODIS数据构建了基于卷积神经网络(convolutional neural network,CNN)的冬小麦估产模型。对2006-2016年中国北方冬小麦核心区的60个地级市进行模型训练,鲁棒性检验以及估产误差空间特征分析。结果表明:1)估产模型在训练集和验证集的均方根误差(root mean square error, RMSE)分别为183.82 kg/hm2、689.72 kg/hm2,决定系数(R2)分别 …
