雷州雷祖神话文本《雷祖志》定型在明清时期。它的直接源头是北宋《雷庙记》,初源是《古雷庙记》。经考证,《古雷庙记》是唐房千里《投荒杂录》中的《陈义》,它记载了雷神及雷州12豪族诞生的神话。在宋代《雷庙记》和明清《雷祖志》中,12族神话消失,雷神神话也变成真实的历史。认清《雷祖志》文本的真相,对于研究雷祖神话有重要意义。 相似文献

山东省德州市砂岩热储开发时间早,供暖工程数量较多,但受社区面积和布局的影响,采灌井距远近不一,过近的采灌井距,势必会加速热突破的发生。为指导今后区内地热工程建设,利用《砂岩热储地热尾水回灌技术规程》(DZ/T0330—2019)中合理井距公式,代入德城区地热地质参数,推导出该区合理井距经验公式。随着地热工程开采量增加,合理井距亦随之增加,当开采量为60m3/h时,合理井距不应低于181m。根据计算,德城区51组采灌对井中,21组采灌对井将会发生热突破,且有8组采灌对井热突破时间不足10年,占比达到了19.6%。为保障采灌工程可持续运行,采灌井应及时调整布局。 相似文献

先秦文学是中国文学诸种样式的开端及萌芽阶段,在文学史上出现较晚的小说也能在先秦散文中找到其萌芽期所具有的多种因素,这在诸子散文中有明确体现,而《孟子》在此方面有突出的特点。虚构,作为小说最核心的因素,在《孟子》中主要以寓言和政治理想蓝图的形式得到彰显;《孟子》中的人物是以孟子为主要代表的活跃在书中的鲜活形象;书中的情节与环境则均借助白描手法得以展现。《孟子》与其他诸子散文一起,为后世小说的产生和发展开拓了广阔的道路。 相似文献

冯梦龙主张戏曲创作要"奇",且"调协韵严",基于此,他对晚明剧坛创作中存在的问题予以批评。这些批评从两个方面展开。在"曲"的方面,他批评了民间传奇创作、文人创新、汤显祖及其追随者等;在"戏"的方面,他提出"奇"的标准——"事奇"和"掀翻窠臼",并批评很多作品难以做到这两点。冯梦龙对晚明剧坛的批评原则立于对形式的推崇,故而有其局限性。 相似文献

Labile organic carbon （LOC） is a fraction of soil organic carbon （SOC） with rapid turnover time and is affected by soil fertilization. This investigation characterized the SOC content, LOC content and LOC distribution in the treatment plots of surface soil erosion at five levels （0-, 5-, 10-, 20- and 30-cm erosion）. The soil had received contrasting fertilizer treatments （i.e., chemical fertilizer or chemical fertilizer ＋ manure） for 6 years. This study demonstrated that both SOC and various LOC fractions contents were higher in the plots with fertilizer ＋ manure than in those with fertilizer alone under the same erosion conditions. The SOC and LOC contents de- creased as the erosion depth increased. Light fraction organic carbon, particulate organic carbon, easily oxidizable organic carbon （KMnO4-oxydizable organic carbon）, and microbial biomass carbon were 27% 57%, 37%-7%, 20%-25%, and 29%-33% higher respectively in the fertilizer ＋ manure plots, than in the fertilizer alone plots. Positive correlations （p 〈 0.05） between SOC content and different fractions contents were observed in all plots except the correlation between total SOC content and water-soluble organic carbon content in the different fertilization treatments. Obviously, fertilizer ＋ manure treatments would be conducive to the accumulation of LOC and SOC in the Black soil of Northeast China. 相似文献

张九龄是唐代岭南诗人之宗,他留传下来的200余首诗中,题咏或咏及岭南的诗篇将近50首.与唐代绝大多数岭南诗不同,张九龄的岭南诗流露出明确的“岭南”乡邦意识,在他的笔下,岭南不是蛮烟瘴雨,而是环境优美,山川明秀,风物宜人.透过这些诗作,我们可以把握张九龄对于岭南乡邦所抱有的完全不同于非粤籍诗人的特定感情 相似文献

Post-fire field measurements of sediment and run off yield were undertaken in natural rainfall event-basis during five rainy months in Korea on a total of 15 small plots: four replica burned unseeded plots, six replica burned seeded plots, and five replica unburned plots. The main aim was to evaluate the effects of vegetation recovery and spatial distribution patterns on sediment and runoff response between and within the treatment replica erosion plots. Six-years after the wildfire, total sediment and runoff yield in the burned unseeded plots with 20%-30% vegetation cover was still 120.8 and 20.6 times higher than in the unburned treatment plots with 100% ground cover, 8.3 and 6.7 times higher than in the burned seeded plots with 70%-80% vegetation cover, while only 1.6 and 2.0 times higher than in the burned seeded plots with 50%-60% vegetation cover, respectively. The differences in sediment and runoff yield between the treatment plots was proportional to total vegetation cover, distance of bare soil to vegetation cover, magnitude of rainfall characteristics and changes in soil properties, but not slope gradient. Three out of the six within-treatment pairs of two replica plots showed large differences in sediment and runoff yield of up to 6.0 and 4.2 times and mean CV of up to 99.1% and 62.2%, respectively. This was due to differences in the spatial distribution patterns of surface cover features, including aggregation of vegetation and litter covers, the distance of bare soil exposed to vegetation cover closer to the plot sediment collector and micro topographic mounds and sinks between pairs of replica plots. Small differences in sediment and runoff of only 0.9-1.4 folds and mean CV of 8.6%-25% were observed where the within-treatment pairs of replica plots had similar slope, total surface cover components and comparable spatial distribution pattern of vegetation and bare soil exposed surface covers. The results indicated that post-fire hillslopes undergoing effective vegetation recovery have the potential to reduce sediment and runoff production nearer to unburned levels within 6-years after burning while wildfire impacts could last more than 6-years on burned unseeded ridge slopes undergoing slow vegetation recovery. 相似文献

Improved understanding of the effect of shrub cover on soil erosion process will provide valuable information for soil and water conservation programs.Laboratory rainfall simulations were conducted to determine the effects of shrubs on runoff and soil erosion and to ascertain the relationship between the rate of soil loss and the runoff hydrodynamic characteristics.In these simulations a 20° slope was subjected to rainfall intensities of 45,87,and 127 mm/h.The average runoff rates ranged from 0.51 to 1.26 mm/min for bare soil plots and 0.15 to 0.96 mm/min for shrub plots.Average soil loss rates varied from 44.19 to 114.61 g/(min·m~2) for bare soil plots and from 5.61 to 84.58 g/(min·m~2) for shrub plots.There was a positive correlation between runoff and soil loss for the bare soil plots,and soil loss increased with increased runoff for shrub plots only when rainfall intensity is 127 mm/h.Runoff and soil erosion processes were strongly influenced by soil surface conditions because of the formation of erosion pits and rills.The unit stream power was the optimal hydrodynamic parameter to characterize the soil erosion mechanisms.The soil loss rate increased linearly with the unit stream power on both shrub and bare soil plots.Critical unit stream power values were 0.004 m/s for bare soil plots and 0.017 m/s for shrub plots. 相似文献

The sword lily Gladiolus palustris Gaudin is protected on European level and listed in Annexes II and IV of the EC Habitat Directive 92/43/EEC. It grows in nutrient-poor, calcareous meadows in central and eastern Europe. Tree encroachment in montane meadows of the European Alps as a result of recent land use changes and the abandonment of traditional farming practices threaten the survival of this species. Conservation-driven mowing is considered a feasible conservation measure for maintaining high species diversity in abandoned semi-natural grasslands. To assess the effects of tenyears of biennial mowing on a grassland community in the Dolomiti Bellunesi National Park, Italy(Site of Community Importance, Natura 2000 network), ten25 m2 plots were established whereby four plots were placed in the mowed area, four in the non-mowed area and two in a small non-mowed patch of grassland inside the mowed area. In each plot the following variables were recorded, total percentage of plant cover, percentage cover of woody species,percentage cover of herbaceous species, percentage cover and number of flowering ramets of G. palustris and a complete list of species and their percentage abundance. Mowed plots showed a higher species richness than non-mowed plots. The number of G.palustris flowering ramets and percentage cover increased manifold in mowed plots compared to nonmowed plots. The resumption of mowing forconservation purposes undertaken by the managing authority halted the process of tree encroachment and avoided a drastic change in plant composition.Periodic mowing(every second or third year) was demonstrated to be a cost-effective conservation measure in non-productive grasslands to keep grasses at bay in favour of forbs of high conversation value. 相似文献
