Abstract Mapping new and old buildings are of great significance for understanding socio-economic development in rural areas. In recent years, deep neural networks have achieved remarkable building segmentation results in high-resolution remote sensing images. However, the scarce training data and the varying geographical environments have posed challenges for scalable building segmentation. This study proposes a novel framework based on Mask R-CNN, named Histogram Thresholding Mask Region-…

2020年，住房和城乡建设部在4省12县开展了乡村建设评价试点工作。本文以这项工作为基础，在尊重乡村建设发展规律和内在逻辑的基础上，构建了一套目标导向、问题导向和结果导向的评价指标与方法。该评价指标与方法能够有效回答三个问题：一是客观回答中国在乡村建设上存在的城乡差距；二是评估村民在乡村建设中的获得感、幸福感，研判就地城市化的发展趋势；三是通过准确评估需求，明确乡村建设重点，为新时期制定乡村建设政策和目标提供依据。
