In the Sichuan province, livelihood security and social development are particularly sensitive to changes in the sloping farmland, due to the region’s large portion of hilly territory and its over-dense population. In this study, we focused on spatiotemporal change of the sloping farmland and its driving forces in the Sichuan province. Sloping farmland areas were extracted from geographic data from digital elevation model (DEM) and land use maps, and the driving forces of the spatiotemporal change were analyzed using a principal component analysis (PCA). The results indicated that, from 2000 to 2015, sloping farmland decreased by 3263 km2 in the Sichuan province. The area of gently sloping farmland (<10◦) decreased dramatically by 1467 km2, especially in the capital city, Chengdu, and its surrounding areas. -
New Empirical Relationships Among Magnitude, Rupture Length, Rupture Width, Rupture Area, and Surface Displacement
Bulletin of the Seismological Society of America, Vol. 84, No. 4, pp. 974-1002, August 1994 New Empirical Relationships among Magnitude, Rupture Length, Rupture Width, Rupture Area, and Surface Displacement by Donald L. Wells and Kevin J. Coppersmith Abstract Source parameters for historical earthquakes worldwide are com piled to develop a series of empirical relationships among moment magnitude (M), surface rupture length, subsurface rupture length, downdip rupture width, rupture area, and maximum and average displacement per event. The resulting data base is a significant update of previous compilations and includes the ad ditional source parameters of seismic moment, moment magnitude, subsurface rupture length, downdip rupture width, and average surface displacement. Each source parameter is classified as reliable or unreliable, based on our evaluation of the accuracy of individual values. Only the reliable source parameters are used in the final analyses. In comparing source parameters, we note the fol lowing trends: (1) Generally, the length of rupture at the surface is equal to 75% of the subsurface rupture length; however, the ratio of surface rupture length to subsurface rupture length increases with magnitude; (2) the average surface dis placement per event is about one-half the maximum surface displacement per event; and (3) the average subsurface displacement on the fault plane is less than the maximum surface displacement but more than the average surface dis placement. Thus, for most earthquakes in this data base, slip on the fault plane at seismogenic depths is manifested by similar displacements at the surface. Log-linear regressions between earthquake magnitude and surface rupture length, subsurface rupture length, and rupture area are especially well correlated, show ing standard deviations of 0.25 to 0.35 magnitude units. -
RESEARCH Eastern Margin of Tibet Supplies Most Sediment to The
RESEARCH Eastern margin of Tibet supplies most sediment to the Yangtze River Gregory K. Wissink* and Gregory D. Hoke DEPARTMENT OF EARTH SCIENCES, SYRACUSE UNIVERSITY, 204 HEROY GEOLOGY LABORATORY, SYRACUSE, NEW YORK 13244, USA ABSTRACT Zircon provenance studies of modern and ancient fluvial systems help reveal the relative contributions and importance of upstream sediment sources. A 2014 study of detrital zircon U-Pb age distributions from the Yangtze River (China) and its tributaries proposed a strong anthropo- genic control on sediment flux. Those data, along with other data from the region, were reanalyzed using multiple detrital zircon U-Pb age distribution comparison techniques and a distribution-mixing model to construct an improved and quantitative view of provenance. The variability in the Yangtze River trunk stream U-Pb age distributions is evaluated with respect to trunk-to-trunk stream comparisons, trunk-to- tributary comparisons, and in mixture models that consider tributary and bedrock contributions, the latter using a comprehensive compilation of bedrock source terranes. Uniformity in the zircon age distribution of the Yangtze River trunk stream is established in the upper reaches, downstream of the first bend, and maintained by the left-bank tributaries to its outlet. Whether considering the bedrock source terranes or only the modern Yangtze River sediments, the major source of sediments contributing to Yangtze River is clearly the eastern edge of the Tibetan Plateau (e.g., Songpan Ganze complex, Longmenshan Range), where rock uplift rates are high. The purported increase in anthropo- genic impact on sediment yield in the lowlands, at least as viewed through detrital zircon age distributions, is insignificant. -
Post-Wenchuan Earthquake Rural Reconstruction and Recovery in Sichuan China
POST-WENCHUAN EARTHQUAKE RURAL RECONSTRUCTION AND RECOVERY IN SICHUAN CHINA: MEMORY, CIVIC PARTICIPATION AND GOVERNMENT INTERVENTION by Haorui Wu B.Eng., Sichuan University, 2006 M.Eng., Sichuan University, 2009 A THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF DOCTOR OF PHILOSOPHY in THE FACULTY OF GRADUATE AND POSTDOCTORAL STUDIES (Interdisciplinary Studies) THE UNIVERSITY OF BRITISH COLUMBIA (Vancouver) September 2014 ©Haorui Wu, 2014 Abstract On May 12, 2008, an earthquake of a magnitude of 7.9 struck Wenchuan County, Sichuan Province, China, which affected 45.5 million people, causing over 15 million people to be evacuated from their homes and leaving more than five million homeless. From an interdisciplinary lens, interrogating the many interrelated elements of recovery, this dissertation examines the post-Wenchuan earthquake reconstruction and recovery. It explores questions about sense of home, civic participation and reconstruction primarily based on the phenomenon of the survivors of the Wenchuan Earthquake losing their sense of home after their post-disaster relocation and reconstruction. The following three aspects of the reconstruction are examined: 1) the influence of local residents’ previous memories of their original hometown on their relocation and the reconstruction of their social worlds and lives, 2) the civic participation that took place throughout the post-disaster reconstruction, 3) the government interventions overseeing and facilitating the entire post-disaster reconstruction. Based on fieldwork, archival and document research, memory workshops and walk-along interviews, a qualitative study was conducted with the aim of examining the earthquake survivors’ general memories of daily life and specific memories of utilizing space in their original hometown. -

Mycosphere 5(1), 27–76, Doi 10.5943/mycosphere/5/1/2 Abstract A total of 36 species of Hypogymnia are known from southwestern China. This region is a center of biodiversity for the genus. Hypogymnia capitata, H. nitida, H. saxicola, H. pendula, and H. tenuispora are newly described species from Yunnan and Sichuan. Olivetoric acid is new as a major lichen substance in Hypogymnia, occurring only in H. capitata. A key and illustrations are given for the species known from this region, along with five species from adjoining regions that might be confused or have historically been misidentified in this region. Key words – Lecanorales – lichenized ascomycetes – Parmeliaceae – Shaanxi – Sichuan – Tibet – Yunnan – Xizang. Introduction The first major collections of Hypogymnia from southwestern China were by Handel- Mazzetti, from which Zahlbruckner (1930) reported six species now placed in Hypogymnia, and Harry Smith (1921-1934, published piecewise by other authors; Herner 1988). Since the last checklist of lichens in China (Wei 1991), which reported 16 species of Hypogymnia from the southwestern provinces, numerous species of Hypogymnia from southwestern China have been described or revised (Chen 1994, Wei & Bi 1998, McCune & Obermayer 2001, McCune et al. -

The current state of strain accumulation and seismic potential along the fault zone have attracted significant attention. In this study, we obtained the interseismic deformation field along the Haiyuan fault zone using Envisat/ASAR data in the period 2003–2010, and inverted fault kinematic parameters including the long-term slip rate, locking degree and slip deficit distribution based on InSAR and GPS individually and jointly. The results show that there is near-surface creep in the Laohushan segment of about 19 km. The locking degree changes significantly along the strike with the western part reaching 17 km and the eastern part of 3–7 km. The long-term slip rate gradually decreases from west 4.7 mm/yr to east 2.0 mm/yr. -

Active Tectonics and Intracontinental Earthquakes in China: the Kinematics and Geodynamics
The Geological Society of America Special Paper 425 2007 Active tectonics and intracontinental earthquakes in China: The kinematics and geodynamics Mian Liu Youqing Yang Department of Geological Sciences, University of Missouri, Columbia, Missouri 65211, USA Zhengkang Shen State Key Laboratory of Earthquake Dynamics, Institute of Geology, China Earthquake Administration, Beijing 100029, China Shimin Wang Department of Geological Sciences, University of Missouri, Columbia, Missouri 65211, USA Min Wang Institute of Earthquake Science, China Earthquake Administration, Beijing 100036, China Yongge Wan School of Disaster Prevention Techniques, Yanjiao, Beijing 101601, China ABSTRACT China is a country of intense intracontinental seismicity. Most earthquakes in west- ern China occur within the diffuse Indo-Eurasian plate-boundary zone, which extends thousands of kilometers into Asia. Earthquakes in eastern China mainly occur within the North China block, which is part of the Archean Sino-Korean craton that has been thermally rejuvenated since late Mesozoic. Here, we summarize neotectonic and geo- detic results of crustal kinematics and explore their implications for geodynamics and seismicity using numerical modeling. Quaternary fault movements and global position- ing system (GPS) measurements indicate a strong infl uence of the Indo-Asian colli- sion on crustal motion in continental China. Using a spherical three-dimensional (3-D) fi nite-element model, we show that the effects of the collisional plate-boundary force are largely limited to western China, whereas gravitational spreading of the Tibetan Plateau has a broad impact on crustal deformation in much of Asia. The intense seis- micity in the North China block, and the lack of seismicity in the South China block, may be explained primarily by the tectonic boundary conditions that produce high devi- atoric stresses within the North China block but allow the South China block to move coherently as a rigid block.
