China is highly susceptible to flood disasters and subjected to great damage every year. Furthermore, the flood frequency has exhibited an increasing trend in recent years. Most flood events, including flash floods and river flood, are induced by rainfall. This study investigates annual variations of rainfall occurrence over China during the period from 2000 to 2015 at the national and regional scale using daily rainfall data from the Tropical Rainfall Measuring Mission. The Mann-Kendall test is performed for trend detection, and statistical data of flood damage published by China’s government, including destroyed crop area, damaged buildings, direct economic loss, percentage of GDP (gross domestic product), and death toll are correlatively analysed with rainfall occurrences. The results show that storm rain events show the greatest variation among three rainfall types (moderate rain, heavy rain and storm rain). The variation coefficients of rainfall over Northeast China, North China, and Northwest China are the highest, whereas that for Southwest China is the smallest. Moderate rain, heavy rain over Central China, and moderate rain over Southwest China exhibits decreasing trends, whereas the remaining exhibit increasing trends. The correlation between the rainfall occurrences and these flood damage indices at the national scale shows that only direct economic loss has a strong positive correlation with rainfall occurrences, and the other indices have weaker correlations. The correlation is strong in three north regions, except for death toll in Northwest China. In contrast, the correlation between flood damage and rainfall is weak in East China, Central China, Southwest China, and South China. Overall, death toll is strongly correlated with the number of damaged buildings, implying that flood fatalities in China are likely associated with building collapse, and are dominated by specific extreme events. This study can provide a scientific reference for flood management in China. 相似文献

洪范池铁矿体赋存于太古宙泰山岩群山草峪组,矿体周围泉水众多,论证矿床开采疏排水能否对泉水产生影响具有重要意义。研究分析表明,朱砂洞组含水层及山草峪组风氧化带裂隙水是矿床充水的直接充水水源,矿床充水水文地质条件属简单类型。泉水出露于寒武纪张夏组含水层中,并且与山草峪组含水层间无水力联系。若张夏组含水层不与采区沟通,矿山生产疏排水不会对泉水产生明显的影响。 相似文献

土地问题是城镇化建设的一个突出问题。目前城镇化进程中还存在依赖土地程度过高、土地闲置、浪费、利用率偏低、城乡用地不能统筹、管理粗放等问题。新型城镇化要走集约、智能、绿色、低碳的道路,由速度扩张向质量提升转型,这就要求城镇化进程中土地规划要更加科学、土地利用要更加节约集约,土地管理要更加精细。 相似文献

采用遥感技术进行土地利用动态监测是一条行之有效的方法。遥感监测方法多种多样。但为了确定变化类型,要引入遥感图像分类方法。遥感分类方法一直是遥感技术方法研究的重要领域。迄今为止,目视解译仍是成功的分类方法;在今后相当长的一段时间内,目视解译分类与计算机自动分类将协调发展。我国土地利用遥感动态监测方法主要采用目视解译、计算机自动分类及目视解译与计算机图像处理相结合的方法,其中,目视解译的方法一直占有重要地位。随着高分辨率传感器的相继问世,利用多平台遥感数据融合进行监测研究将有利于提高分类、监测精度。我国的土地利用遥感监测研究正深入开展,并将在计算机信息提取及监测方法上取得更大的成果。 相似文献

Approach to Mountain Hazards in Tibet, China 总被引：1，自引：1，他引：0

Tibet is located at the southwest boundary of China. It is the main body of the Qinghai-Tibet Plateau, the highest and the youngest plateau in the world. Owing to complicated geology, Neo-tectonic movements, geomorphology, climate and plateau environment, various mountain hazards, such as debris flow, flash flood, landslide, collapse, snow avalanche and snow drifts, are widely distributed along the Jinsha River (the upper reaches of the Yangtze River), the Nu River and the Lancang River in the east, and the Yarlungzangbo River, the Pumqu River and the Poiqu River in the south and southeast of Tibet. The distribution area of mountain hazards in Tibet is about 589,000 km^2, 49.3% of its total territory. In comparison to other mountain regions in China, mountain hazards in Tibet break out unexpectedly with tremendously large scale and endanger the traffic lines, cities and towns, farmland, grassland, mountain environment, and make more dangers to the neighboring countries, such as Nepal, India, Myanmar and Bhutan. To mitigate mountain hazards, some suggestions are proposed in this paper, such as strengthening scientific research, enhancing joint studies, hazards mitigation planning, hazards warning and forecasting, controlling the most disastrous hazards and forbidding unreasonable human exploring activities in mountain areas. 相似文献

The removal of bed material from active river channels usually affects the bed profile of the streambed, causing progressive degradation upstream and downstream of the extraction site. These effects can extend for kilometers affecting hydraulic structures located in the vicinity of the river reach. In this paper, the geomorphic effects of gravel mining are reviewed and summarized. Some cases in Venezuelan streams are presented to illustrate the problem. To describe the processes of erosion and sedimentation in a gravel extraction pit, a recent developed mathematical model for the simulation of flow and sediment transport in gravel-cobble bed streams is applied to a hypothetical case of gravel mining in a river channel. A simple rectangular dredge pit is imposed as initial condition in the channel bed, and changes in bed elevations and grain size distribution of bed material are calculated by using the numerical model. The process of deposition within the pit, and the downstream and upstream migration of the erosion wave are well simulated by the model and closely resemble the phenomena observed in laboratory experiments. The response of the friction coefficient to the changes in flow and bed elevations shows the importance in modeling adequately flow resistance and sediment transport in gravel-cobble bed streams. 相似文献
