| 1 | Effect of sediment on concentration of dissolved phosphorus in the Three Gorges Reservoir显示文摘超营养作用和海藻的花蕾在 2003 自从水库的被坝所围住的水一直在发生在三座峡水库。溶解的磷(DP ) 的集中是为海藻的花蕾的主要控制因素之一。好沉积吸附从而影响 DP 的集中的 DP。三座峡水库的 DP 集中上的沉积减小的效果在这份报纸被讨论。样品从长江和它的支流被拿,即 Minjiang 河和 Tuojiang 河。沉积样品的水样品和可得到的磷,全部的磷,和修理磷的能力的 DP 集中被分析。沉积吸附的磷的数量是在长江的大约 3% 全部的 DP 负担。一个实验在模仿 DP 集中,沉积集中,和骚乱的实验室被做。结果证明 DP 的相当高数量被沉积吸附。沉积的吸附能力是 135 mg/kg,吸附的最高的率是到 0.145 次的 29 mg/kgsed 什么时候 ann 吗?? | CAO Zhijing ZHANG Xinbao AI Nanshan | 2011 | International Journal of Sediment Research2011，26，1： | 14 |
| 2 | Meanders of the Jialing River in China: Morphology and formation显示文摘As a fundamental category of river system, comparisons in diverse regions and types with quantitative parameters on meander morphology will help to distinguish different characteristics and approach formations and evolutions. It also can provide scientific basis of geomorphology for their protections and exploitation of the meander resources. Based on the images of Google Earth, meanders’ parame- ters are proposed and then measured and calculated. The result suggests that incised meanders in the Jialing River are among the most complex, irregular and sinuous channels. Special river gradient, geological structures, strata and lithology, backwater effect of landform are key factors to shape me- anders of the Jialing River. The evolution of meander in the Jialing River obeys the principle of mini- mum-maximum energy dissipation. Easy acquisitions of remote sensing data make regional and global comparisons possible, and then the differences of formations can be explored. The morphology can probably provide an evidence of antecedent river and demonstrate the channel incisions and crustal uplifts. Meander core in Chinese is named after the isolated hills in the Jialing River. The incised me- ander is a kind of resource and needs to be protected. | ZHANG Bin AI NanShan HUANG ZhengWen YI ChengBo QIN FaCao | 2008 | Chinese Science Bulletin2008，53，2： | 6 |
| 3 | Scaling behavior of magnitude clusters in aftershock sequence:An example of the Wenchuan Earthquake,China显示文摘The Gutenberg-Richter and Omori Laws, which are generally used to characterize the temporal distribution of aftershock, failed to reflect the statistic properties of climatic outbreak of aftershock energy. Based on a new concept of magnitude clusters describing the fluctuation of aftershock energy release of the Wenchuan Earthquake, we discovered that the pattern of the continuous high-magnitude aftershock follows a power-law rather than a non-Poisson distribution. This suggests that the after-shocks with high magnitudes are statistically clustered. We then divided the aftershock sequences into three sections and demonstrated that though the probability of strong outbreaks decreased with time, there exists a high possibility of the occurrence of isolated high-magnitude aftershocks in the future. Based on self-organized criticality theory, the mechanisms of the power-law pattern of magnitude clusters are discussed. This discovery may be used to guide future aftershock predication and the associated post-disaster reconstruction. | ZHANG Bin SHI Kai LIU ChunQiong YAO LingKan DI BaoFeng AI NanShan | 2012 | Science China Earth Sciences2012，55，3： | 4 |
| 4 | Analysis of Ecosystem Degradation Factors in Yuanmou Arid-Hot Valleys Based on Interpretative Structural Model显示文摘For ecological restoration and reconstruction of the degraded area, it is an important premise to correctly understand the degradation factors of the ecosystem in the arid-hot valleys. The factors including vegetation deg-radation, land degradation, arid climate, policy failure, forest fire, rapid population growth, excessive deforestation, overgrazing, steep slope reclama-tion, economic poverty, engineering construction, lithology, slope, low cul-tural level, geological hazards, biological disaster, soil properties etc, were selected to study the Yuanmou arid-hot valleys. Based on the interpretative structural model (ISM), it has found out that the degradation factors of the Yuanmou arid-hot valleys were not at the same level but in a multilevel hier-archical system with internal relations, which pointed out that the degradation mode of the arid-hot valleys was 'straight (appearance)-penetrating-back-ground' . Such researches have important directive significance for the restoration and reconstruction of the arid-hot valleys ecosystem. | ZHANG Bin LIU Gangcai AI Nanshan SHI Kai SHU Chengqiang | 2008 | Wuhan University Journal of Natural Sciences2008，13，3： | 2 |

| 10 | Minority population and sustainable development in mountain regions a case study of the Tibetan inhabited region in Sichuan, China显示文摘China boasts 56 nationalities who are mostly inhabited in the sparsely populated mountain regions in West China. Like many other places in the Han nationality distributed regions, minority nationality inhabited regions are also facing the challenge of sustainable development in terms of both natural and human factors. Taking the Tibetan inhabited regions (TIR) in Sichuan Province as a case, this paper points out some major problems in the process of economic development in perspective of sustainability and leaves some hints for development strategies. While natural conditions such as geological instability are playing a major role to the environmental degradation, human activities and improper use of resources might constitute an important agent in the environmental deterioration. In order to promote local economic development and improve people’s living standard, sustainable planning is expected to be made and people’s awareness of sustainability should be strengthened. | CHEN Yong HE Ginxi Institute of Population Research, Sichuan University, Chengdu 610064, CHINA AI Nanshan Institute of Environmental Science & Engineering, Sichuan University, Chengdu 610064, CHINA | 1998 | Journal of Geographical Sciences1998，8，4： | 0 |

| 12 | Classification and detection of dominant factors in geospatial patterns of traditional settlements in China显示文摘The geospatial distribution pattern in traditional Chinese settlements(TCSs)reflects the traditional harmony between humans and nature,which has been learned over centuries.However,TCSs have experienced serious disturbances by urbanization and migration.It is crucial to explore the local wisdom of geospatial patterns and dominant factors for TCSs at the national scale in China.This study sought to determine the geospatial wisdom of traditional settlements to enrich our future settlement development with the aim of establishing Chinese settlement values for modern living.Herein,a dataset of 4000 TCSs were analyzed and clustered for environmental factors that affect their geospatial patterns by machine learning algorithms.We concluded that(1)five geospatial patterns of TCSs were clustered on a national scale,and the threshold of environmental factors of TCS groups was detected.(2)Environmental conditions and settlement concepts interacted and determined the similarities and differences among TCS groups.(3)The key boundary for TCSs and the dominant factors for each zone were determined,and topographical conditions and hydrologic resources played significant roles in all five TCS zones.This study provides a better understanding of the adaptability of the environment in relation to the TCSs and aids in planning TCS conservation and rural revitalization. | WU Shaolin DI Baofeng Susan L.USTIN Constantine A.STAMATOPOULOS LI Jierui ZUO Qi WU Xiao AI Nanshan | 2022 | Journal of Geographical Sciences2022，32，5： | 0 |
