Abstract:In this paper the expansion process and patterns of urban land in Shandong Province are analyzed from the perspectives of time and space based on the four phases of land use data in 1990, 2000, 2010, and 2020 with the spatial correlation index, hot and cold spot analysis, and the elasticity coefficient of urban land growth. The results show that: (1) In the past three decades, the expansion intensity and expansion speed of urban land in Shandong Province are relatively fast, and the land urbanization has maintained a relatively high growth level. The characteristics of aggregation and dispersion for urban land expansion change over time. The differences of land urbanization level between cities are shrinking, indicating it is of "multi-polar development, decentralized expansion". (2) Qingdao, Jinan and Yantai-Weihai are the core areas of urban land expansion in Shandong Province, but in recent years their central polarizing role has weakened; Weifang, Dezhou and Linyi has become the secondary central areas of urban land expansion and they are developing Faster. The land urbanization pattern in Shandong will take "Jinan - Qingdao - Linyi" as the core in the future.(3) The elasticity coefficient of urban land growth is becoming more and more reasonable on the whole, which shows that the phenomenon of pursuing urban land expansion blindly and ignoring urban population development has been alleviated, but there are still some cities like Binzhou and Linyi where land urbanization grows faster than population urbanization which will lead to the phenomena of empty city. The results of this paper can provide spatiotemporal data support in its healthy expansion of urban land for Shandong Province during its new type of urbanization.……..(10 Points, Times New Roman)

	Abstract:In order to study the land use change situation of Qingdao in recent 10 years, this paper used the land Use classification system of China\'s coastal zone to overlay the land use of 2015 by visual interpretation with 2005 data in Arcgis10.2. The results showed that the residence of Qingdao increased 1612.3km2, the area of urban mining increased 351.2km2, the area of woodland increased 499.7km2, and the area of arable land decreased 1911.9km2, the grassland areas decreased 342.4km2, and the water body decreased 277.4km2. These changes were mainly due to the speed of urbanization, another reason was that the Government attached importance to environmental issues, vigorously carried out afforestation and returned farmland to forest. The research provided scientific basis for local government departments to formulate targeted land use planning and policies, which is of great practical significance for regional comprehensive, coordinated and sustainable development.

	3. Association of the East Asian subtropical westerly jet with the Southwest Asian summer monsoon: A diagnostic analysis on heavy rain events in Yunnan Province, China

	Abstract:By using daily observations and the NCEP/NCAR reanalysis data during 1960-2011, a diagnostic analysis is performed to investigate the association of the East Asian subtropical westerly jet (EASWJ) with the Southwest Asian summer monsoon (SASM) on heavy rain events in Yunnan Province of southwest China during SASM prevailing season. The diagnostic analysis shows an anomalous divergence circulation pattern at upper level (200 hPa) over Eurasian continent that corresponds well to the negative anomaly of EASWJ intensity during the heavy rain events in boreal summer in Yunnan Province. Meanwhile, a low-level jet stream with abundant water vapor originated from the Arabian Sea and Bay of Bengal provides necessarily dynamic and water conditions for heavy rain mechanism. The study further shows that the weakening of the EASWJ during heavy rain events in Yunnan Province is associated with the decrease in the meridional air temperature gradient in northern mid-latitude (30o-45oN).

	Abstract:We present topographic, geomorphologic and compositional characteristics of a 1 ×1 (~660 km2) region centered near the landing site of Chang'E-3 using the highest spatial resolution data available. We analyze the topography and slope using Digital Terrain Model (DTM) generated from Terrain Camera (TC) images. The exploration region is overall relatively flat and the elevation difference is less than 300 m, and the slopes of 80% area are less than 5 . Impact craters in the exploration region are classified into four types based on their degradation states. We investigate the wrinkle ridges visible in the exploration region in detail using TC and Lunar Reconnaissance Orbiter (LRO) Narrow Angle Camera (NAC) images. We calculate FeO and TiO2 abundances using Multispectral Imager (MI) data, and confirm two basaltic units: the northern part belongs to Imbrian low-Ti/very-low-Ti mare basalts, and the southern part is Eratosthenian low-Ti/high-Ti mare basalts. Finally, we produce a geological map and propose the geologic evolution of the exploration region. We also suggest several rover traverses to explore interesting targets and maximize the potential scientific output.

	Abstract:A subpixel unmixing algorithm, the constrained energy minimization (CEM) was used to detect significant alteration minerals from the ASTER surface reflectance image data covering the south Chocolate Mountains area, California, U.S.A. For visualization purposes, a GIS icon-based visualization technique was designed and implemented to co-visualize these four alteration minerals. The results illustrate that ASTER data is very valuable for mineral mapping due to the presence of the six SWIR bands. The icon-based co-visualization has advantages of visualizing multiple spatial data layers in a raster GIS model. This is helpful for the analysis of minerlaization processes.

	Abstract:In this paper, the star dunes with five arms are simulated numerically in order to make clear the mechanism of the formation. The numerical method employed in this study can be divided into three parts: (1) Calculation of the air flow above the sand dunes; (2) Estimation of the sand transfer caused by the flow through the friction; (3) Determination of the shape of the sand ground. Since the computational area has been changed due to the last step, these procedures are repeated until typical shapes of the sand dunes are formed. When the winds blow from five directions, the sand dune extends at five directions and becomes the shape of a star with five arms.

	Abstract:The structural properties of jadeite are investigated using plane-wave pseudopotential density functional theory method. As a function of pressure, the monoclinic cell parameters were calculated and the compressibility coefficients are 0.0025, 0.0024 and 0.0025 GPa-1, respectively. The bond length, bond angle, and distortion variation were studied in order to obtain the information of polyhedral compression. The Birch-Murnaghan equation of state was considered in the theoretical calculations of E-V and P-V data for the bulk modulus B0, which were compared with the result based on the linear compressibilities. Comparison between the calculated B0 values and the experimental data suggested that the model provides reasonable insights into crystallographic and physical properties of jadeite.
