针对目前大范围地形绘制中对地形块间裂缝进行图元级精确修补会额外占用计算机资源,或者进行简单视觉掩饰而导致几何与纹理空间缺乏连贯性的问题,基于Melax快速网格简化算法,提出了保持边界的边折叠地形简化算法.首先定义了保持点与控制点概念,给出保持点的数量选择方法与控制点的精简策略,并通过改进边折叠规则和代价计算公式实现了边界不变的网格简化;然后按聚类层次结构表示思想,将简化网格与原规则网格层叠组织,以顶点索引方式保证地形整体快速批量操作,构造出一种具有保持边界特性的地形格式.实验结果证明,该算法在保持地形边界的同时,能有效地缓解边界图元稠密现象,且比Melax算法更好地保留了地形特征;在此基础上形成的地形格式,在飞行模拟测试中既可保证较高帧率,又显示出无缝拼接平滑过渡的良好视觉效果.

针对高分辨率遥感影像中道路形状结构错综复杂,出现窄小型道路提取错误或漏分的问题,提出一种基于空洞空间金字塔池化和注意力机制的轻量化遥感影像道路提取方法。首先,在原始高分辨率网络(HRNet)基础上,通过引入空洞空间金字塔池化模块,实现多尺度道路信息融合;再引入挤压激励通道注意力机制,增强网络特征表征质量;最后使用深度可分离卷积方法改进网络残差模块实现模型轻量化,以降低模型计算复杂度。在公开数据集上进行了模型性能测试,实验结果表明,文章所提算法的准确率、精确率、召回率、F1分数和平均交并比,相比原始HRNet分别提升了5.35%、2.15%、4.1%、3.15%和14.34%,且减少了36.1%的参数数量;相比其他网络,该算法突出了细小道路的特征,道路预测结果连续性、完整性好,并且模型小易于部署在实时检测设备中,有效改善了道路提取任务中错分和缺失的情况,是一种适应性更强、分割精度更高、更轻量化的多尺度道路提取算法。

The Bohai Bay Basin contains many depressions with varying degrees of hydrocarbon enrichment associated with the geological structures of different depressions. This study discussed the relationship between the geological structures and hydrocarbon enrichment of the depressions in the Bohai Bay Basin. Based on the Paleogene strata distribution and the length to width ratio of different depressions, their geological structures are divided into three types in plan-view： open（length/width 〈 2）, narrow（length/width 〉 4） and transitional types（length/width 2-4）. In cross section, the geological structures can be divided into dustpan I, dustpan II and double-faulted types. Based on tectonic evolution and sedimentary characteristics, the depressions are classified into early-formed, inherited and late-formed categories. Generally, narrow depressions are mainly located in the northeast and southwest of the Bohai Bay Basin, while open depressions are dominantly distributed in the central area of the basin; late-formed depressions are mainly around the Bohai sea area, and early-formed depressions are mostly located in the periphery of the basin. Geological structures of the depressions control the formation of the source, reservoir and cap rocks as well as hydrocarbon accumulation setting, and further influence the pay zones and oil-bearing sequence. In detail, dustpan II and doublefaulted depressions mainly have A-type sags, which often possess better hydrocarbon generation conditions than dustpan I ones; hydrocarbons in open dustpan II depressions tend to accumulate in the central uplift areas or buried hill, while those in narrow dustpan I depressions always accumulate in gentle slope belts. The oil-bearing sequence for different evolutional depressions corresponds well with the sedimentary strata of the main development stages of depressions. In early-formed depressions, hydrocarbons are mainly enriched in deeply buried reservoirs, while in late-formed depressions hydroca

Significant differential hydrocarbon enrichment occurs in depressions in a petroliferous *** are multiple depressions in the Bohai Bay Basin, and each depression as a relatively independent unit of hydrocarbon generation, migration and accumulation, contains significantly different hydrocarbon generation conditions and enrichment degree. On the basis of previous documents and a large number of statistical data, this work comparatively analyzed the differential hydrocarbon enrichment and its major controlling factors in depressions of the Bohai Bay Basin. The results show that depressions in the Bohai Bay Basin have various hydrocarbon enrichment degrees, and can be categorized into four types, namely enormously oil-rich, oil-rich, oily and oil-poor depressions. In general, the enormously oil-rich and oil-rich depressions are distributed in the eastern part of the basin along the Tan-Lu and Lan-Liao faults, whereas depressions in the western part of the basin are poor in hydrocarbons. Moreover, the vertical distribution of hydrocarbons is also highly heterogeneous, with Pre-Paleogene strata rich in hydrocarbons in the northern and western depressions, Paleogene strata rich in hydrocarbons in the entire basin, and Neogene strata rich in hydrocarbons in the off-shore areas of the Bohai Bay Basin. From early depressions in onshore areas to the late depressions in offshore areas of the Bohai Bay Basin, the source rocks and source-reservoir-cap rock assemblages gradually become younger and shallower, and the hydrocarbon resource abundance gradually increases. Hydrocarbon supplying condition is the key factor constraining the hydrocarbon enrichment for different depressions,while the main source-reservoir-cap rock assemblage, sufficient hydrocarbons and the transportation capacity of faults control the vertical distribution of hydrocarbons. The main factors controlling hydrocarbon enrichment are different for different layers. The hydrocarbon supplying condition of
