高分辨率遥感图像中提取的土地覆盖信息在城市规划建设和土地利用等领域具有巨大的价值,但由于土地覆盖类型复杂、光谱差异性较小等因素,目前对土地覆盖类别进行高质量的语义分割仍然受到一定限制。因此,针对该问题提出了一种新颖的全连接网络MFC-Net,该模型采用全新的基于点积注意力的空洞空间金字塔池化模块(DPA-ASPP),提高了聚合上下文信息方面的能力及效率。更进一步的,针对不同尺度的特征提出了注意力增强融合模块(AEFM)来增强特征表示,改善不同形状和大小地物的分割效果。该模型充分利用了高分辨率遥感影像中丰富的上下文信息及多尺度信息,在LoveDA大型遥感图像数据集上取得了优于当前主流模型的分割结果(84.26%MPA和69.67%MIOU)。

华南板块由扬子克拉通和华夏地块在新元古代碰撞拼合形成,其西南部的缝合带位置存在强烈争议.本文基于一条南北向宽频带流动台阵天然地震数据,利用SKS波分裂研究华南西南部上地幔各向异性特征的南北向变化.分裂测量结果显示,26°N以南的右江盆地快波偏振方向为E-W或NEE-SWW方向,分裂时差为0.5~2.5 s,变化范围较大;川东褶皱带存在较多空解,快波偏振方向以近东西向为主,分裂时差在0.5~1.5 s范围内变化;在右江盆地北缘和川东褶皱带的过渡区域(约26°N附近)各向异性明显较弱.结合前人的上地幔速度成像结果,我们认为川东褶皱带与右江盆地过渡带是扬子克拉通的南边界,在其下方北侧的川东褶皱带巨厚的岩石圈向南转变成较薄的岩石圈,陡变的岩石圈边界引起了软流圈上涌,软流圈的垂向运动导致其水平方位各向异性较弱.
