基于层次匹配的面状要素几何匹配方法研究

空间数据增量信息提取是空间数据库增量更新的基础,而要素几何匹配则为空间数据增量信息提取的关键流程之一。针对面状要素几何匹配时所产生的单一匹配算子匹配准确度低,以及多算子加权匹配算法匹配效率低、冗余度高、结果不准确等情况,本文提出一种基于多层次匹配的面状要素几何匹配算法。该算法以反映面状要素位置、大小、形状特征的质心匹配算子、面积重叠度算子以及转向角函数匹配算子为基础,并按各算子复杂度进行层次匹配规则设计,以提高算法效率、保证匹配的准确性。本文通过2种方法进行对比实验,结果表明：层次匹配算法匹配完整度和准确度均能达到90%以上,可以很好地进行面状要素几何匹配;与加权匹配方法相比效率更高,代价更小,且所得匹配结果比加权匹配方法所得结果更加准确。

Studies on the breeding habits of the minke whale (Balaenoptera acutorostrata) in the Yellow Sea

Minke whales caught in the Yellow Sea range from 4.16 m to 8.60 m in length with an average length of 6.93 m for the female and 6.14 m for the male. Sex ratio of the female is 74.3%. The pregnancy ratio of all sexually matured females is 65.8%. The minimum size of the pregnant whale observed is 6.60 m in length. Females having a body length of more than 7 m long are all sexually matured. According to the studies on the embryos obtained from the females caught in the northern Yellow Sea, there is only one breeding season each year. Mating mostly occurs from July through September, and the length of pregnancy is ten to eleven months with the peak of calving from May through July. Most females breed one calf each time, only two cases with twins. Sex ratio of female fetus is 56.6%, and the newly born calf measures 250–270 cm in body length. This paper was published in Chinese inOceanologia et Limnologia Sinica 13 (4): 338–345.

Assessment of prospective hazards resulting from the 2017 earthquake at the world heritage site Jiuzhaigou Valley,Sichuan, China

On August 8, 2017, a Ms = 7.0 magnitude earthquake occurred in the Jiuzhaigou Valley, in Sichuan Province, China(N: 33.20°, E: 103.82°). Jiuzhaigou Valley is an area recognized and listed as a world heritage site by UNESCO in 1992. Data analysis and field survey were conducted on the landslide, collapse, and debris flow gully, to assess the coseismic geological hazards generated by the earthquake using an unmanned aerial vehicle(UAV), remote-sensing imaging, laser range finders, geological radars, and cameras. The results highlighted the occurrence of 13 landslides, 70 collapses, and 25 potential debris flow gullies following the earthquake. The hazards were classified on the basis of their size and the potential property loss attributable to them. Consequently, 14 large-scale hazards, 30 medium-sized hazards, and 64 small hazards accounting for 13%, 28%, and 59% of the total hazards, respectively, were identified. Based on the variation tendency of the geological hazards that ensued in areas affected by the Kanto earthquake(Japan), Chi-chi earthquake(Taiwan China), and Wenchuan earthquake(Sichuan China), the study predicts that, depending on the rain intensity cycle, the duration of geological hazard activities in the Jiuzhaigou Valley may last over ten years and will gradually decrease for the following five to ten yearsbefore returning to pre-earthquake levels. Thus,necessary monitoring and early warning systems must be implemented to ensure the safety of residents,workers and tourists during the construction of engineering projects and reopening of scenic sites to the public.
