Self-supervised graph representation learning has recently shown considerable promise in a range of fields, including bioinformatics and social networks. A large number of graph contrastive learning approaches have shown promising performance for representation learning on graphs, which train models by maximizing agreement between original graphs and their augmented views(i.e., positive views). Unfortunately, these methods usually involve pre-defined augmentation strategies based on the knowledge of human experts. Moreover, these strategies may fail to generate challenging positive views to provide sufficient supervision signals. In this paper, we present a novel approach named graph pooling contrast(GPS) to address these *** by the fact that graph pooling can adaptively coarsen the graph with the removal of redundancy, we rethink graph pooling and leverage it to automatically generate multi-scale positive views with varying emphasis on providing challenging positives and preserving semantics, i.e., strongly-augmented view and weakly-augmented view. Then, we incorporate both views into a joint contrastive learning framework with similarity learning and consistency learning, where our pooling module is adversarially trained with respect to the encoder for adversarial robustness. Experiments on twelve datasets on both graph classification and transfer learning tasks verify the superiority of the proposed method over its counterparts.

为了解林下植被物种多样性随林龄的恢复轨迹,在广东省龙眼洞林场采用空间替代时间的方法,选取以相同方式经营的6个林龄序列(10、15、20、25、30和34年)的红锥(Castanopsis hystrix)人工林为研究对象,利用α和β多样性指数分析物种多样性随着林龄的变化趋势.结果显示:(1)共发现植物32科45属51种,其中灌木层物种有23科33属39种,草本层有9科12属12种.(2)灌木层和草本层的物种丰富度随着林龄的变化趋势类似,呈现先增加后下降的趋势;Simpson优势度指数和Shannon-Wiener多样性指数随着林龄的增加呈现先增加后下降的趋势,其中灌木层和草本层Simpson优势度指数的最大值均出现在20年的林龄;灌木层和草本层的Pielou均匀度指数表现较为平稳.(3)草本层植被群落的Jaccard相似性指数和Morisita-Horn相似性指数沿恢复轨迹呈下降趋势,且草本层植被的Jaccard相似性指数和Morisita-Horn相似性指数呈显著正相关.上述结果表明不同林龄红锥人工林林下植被物种多样性变化在扰动后的恢复过程中呈现非线性关系,与传统观点一致.未来该红锥人工林林下植被随着恢复时间会维持一个较为稳定的状态.

潜山油气藏是中国东部储量丰富的勘探开发对象,但受构造活动、岩性变化和流体溶蚀等影响,其内幕储集空间非常复杂。通过对胜利油区埕岛潜山的岩心观察,发现断层活动导致下古生界碳酸盐岩形成裂缝段(裂缝密度小于10条/m)、碎裂岩(裂缝密度大于10条/m)和角砾岩(砾径为2~8 cm),其中角砾岩和碎裂岩的溶蚀现象明显、砾间空隙含油性好,而裂缝段及一般碳酸盐岩的含油性较差。利用测井和地震资料,提出了断层与裂缝段、碎裂岩、角砾岩的5种组合,查明潜山内幕以断层破碎带(碎裂岩-角砾岩)为主体的新型储集体的分布规律。进而利用岩矿鉴定和地化分析,阐明了地表水和热液流体对断层附近碎裂岩、角砾岩的溶蚀情况,认为油气成藏期地表水对断层破碎带形成储集体起到了控制作用。这种新型储集体的预测和评价,有助于查明潜山内幕储集空间及油气分布特征,也有利于复杂潜山内幕油藏的高效开发。
