	Abstract:Reservoir connection is a key factor for water flooding recovery. Ways for connection evaluation is though well test or radioactive injection and its output survey. In fact there are great deference in permeability among different genetic sandbodies. In L3 block the permeability of distributaty channel is 4 to 10 times higher than the other genetic sandbody such as levee, crevasse splay sand. Because of its densely well space, we can get detailed genetic sandbodies distribution for every layer. In the framework it is easy to evaluate the connectivity of every layer among inject wells and output wells based on the genetic sandbodies distribution. Generally wells drilled on the same distributay channel or on the different channel sandbody which superposed together is well connected, while the wells suited on the channel and other genetic sand is poor connected. In L3 fault block, the upper layer is better connected than lower layer. The connectivity evaluation is proved by the output and press data. As a summery we believe it is possible to evaluate the connectivity through reservoir architecture analysis.

	Abstract:We collected a 118-cm-long and well-preserved sediment profile, which contains a large number of mollusk shell fragments - predominantly Mya truncata, from a paleo-notch on Ny-Ålesund, Svalbard, high Arctic. AMS14C dating and stable oxygen and carbon isotope analyses were performed on the shell fragments. The average reservoir-corrected radiocarbon age is ~9,400 yr B.P., indicating the mortality time of fossil mollusk in the paleo-notch sediments. The aragonite isotopic temperature equation was calibrated for Ny-Ålesund based on the δ18O profiles of modern mollusks. The calculated paleotemperature was between – 0.52 and + 4.78 ºC, warmer than today by about 1 ºC; and this is consistent with the reconstructed Sea Surface Temperature (SST) in west Svalbard. As inferred from reduced insolation, weakened thermohaline circulation (THC), and abrupt decreased SST, there was an abrupt cooling event at ~9,400 yr B.P.; and this cooling event very likely caused the mortality of the fossil mollusks. While great amount of attention has been paid towards global warming in today\\\

	Abstract:The Sb concentrations in the soil, moss and sediment samples from Ny-Alesund, Svalbard, were determined. The Sb concentrations in the soil and moss samples from the area with previous coal mine are substantially higher than those from the area without, apparently caused by coal mining activities. The studied moss Dicranum anaqustum has a great enrichment of Sb, and thus a good potential of being used as bio-indicator for the Sb pollution in Ny-Alesund. The Sb level in the surface 10cm sediments of one sediment column has a striking associated with human activities such as coal mine exploitation and utilization and oil burning.

	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.

	Abstract:Molar-tooth carbonatites can be found in almost all the Neoproterozoic carbonatite strata in Northern Anhui and Jiangsu Provinces. According to their features in different strata, two molar-tooth carbonatite types can be differentiated in this area. Type 1 molar-tooth carbonatites coexisted with stromatolite bioherms, gravels, debris, slump structures, swash channels and hummocky crossbeddings, were formed in the upper Liulaobei Formation and Jiuliqiao Formaiton which belong to the lower Neoproterozoic in this area. Type 2 molar-tooth carbonatites consisted in widely spread rhythmic units with graded beds and typical erosion surfaces, were formed in other Formations which belong to the upper Neoproterozoic in this area. The initial forming power of the molar-tooth carbonatites in this area might be the crustal movements which were caused by the break-up of the Rodinia. Type 1 molar-tooth carbonatites formed in tempestuously changing environments might be a signal of the break-up prelude of the Rodinia, while Type 2 molar-tooth carbonatites formed in steadily, periodically changing environments might indicate the intermittent release of the earth stress during the break-up period of the Rodinia.

	Abstract:Estuaries are biologically productive and diverse coastal areas that are also vital to commerce, transportation, and recreation activities. In this paper, we demonstrate the potential of the hyperspectral data for monitoring heavy metal pollution such as zincum(Zn) and plumbum(Pb) in estuary. A series of methods were used to manage the basical spectral reflectivity and the sensitive bands for estimation of above parameters. The Hyperion spectra show band to band spikes or dips, a selection based on single bands could match some spikes. The binning of bands were thus used instead of the single channels to develop the hyperspectral models. Quantitive models were presented to simulate the amount of heavy metal of Zn and Pb in estuary water according to the choosen largest value of R2 between the experimental amount of Zn and Pb and the corresponding worked reflectivey on the sensitive bands. The validation of these models showed that the relative RMSE values were basically less than 35%, which indicating that Hyperion imagery as a bench-mark for moving towards operational use of RS-related technologies that, integrated with traditional survey programmes, could provide useful information to implement the dynamic monitoring of heavy metal pollution in estuary.

	Abstract:Three-dimension green biomass refers to the volume formed by stems and leaves of a plant. It overcomes the limitation of two-dimension indices, and more accurately reflects the rationality of the plant spatial constitution and the level of ecological benefit. This paper summarizes the research advances on TGB, expatiates its concept, introduces main calculate methods of TGB, and puts forward some key problems and the view on research direction of TGB measurement. The research of TGB measurement not only is important for the establishment of a city’s green database, but also provides an important index for the evaluation of urban green area. Therefore, it is useful for studying of the green environmental benefit.

	Abstract:Rapid economic development during the last three decades has caused a large urban expansion in China, especially in the eastern and coastal areas of China. In these areas, a special urban expansion mode, Desakota (Semi-urbanization), is very popular. Wujiang, a typical Desakota are in Sunan, is chose as the research area to study the special urban expansion based on multi-temporal Remote Sensing and GIS. In this study, maximum likelihood supervised classification and post-classification change detection techniques were applied to Landsat MSS/TM images acquired in 1978, 1986, 1993, 2000, and 2004, respectively, to map land cover changes in the Wujiang, China. A supervised classification was carried out on the five images individually with the aid of ground truth data. Ground truth information collected during two field trips conducted between 2005, 2007 and land use map of 1997, 2004 were used to assess the accuracy of the classification results. Using ancillary data, visual interpretation and expert knowledge of the area through GIS further refined the classification results. Post-classification change detection technique was used to produce change image through cross-tabulation calculation. Changes among different land cover classes were assessed. During the study period, a very severe land cover change has taken place as a result of industrial and urban development projects. These changes in land cover led to cropland degradation in the study area. Result indicates the environmental impacts of urban sprawl of Wujiang. The research suggests that human activities, such as urbanization and industrialization, were playing a much more significant role in the change of land cover and landscape pattern during the last 30 years from 1978.

	Abstract:In this paper, a new parameter is proposed for ship detection in ocean regions. Via extending the idea of polarization entropy, the polarization cross-entropy is proposed based on the eigen-decomposition of the polarimetric coherency matrix. The new parameter is evaluated to be effective in ship detection. A CFAR ship detection method is yielded by using the proposed polarization cross-entropy. Experimental results have shown the effectiveness of the new method in ship detection.

	10. Crustal Composition of China Continent Constrained from the Heat Flow Data and the Helium Isotope Ratio of Underground Fluid

	Abstract:Based on conservation of energy principle and heat flow data in China continent, the upper limit of 1.3 Wm-3 heat production is obtained for continental crust in China. Furthermore, using the data of heat flow and helium isotope ratio of underground fluid, the heat productions of different tectonic units in China continent are estimated in range of 0.58~1.12 Wm-3 with a median of 0.85 Wm-3. Accordingly, the contents of U, Th and K2O in China crust are in ranges of 0.83~1.76g/g, 3.16~6.69g/g, and 1.0~2.12%, respectively. These results indicate that the abundance of radioactive elements in crust of China continent is much higher than that of Archean crust; and this fact implies China’s continental crust is much evolved in chemical composition. Meanwhile, significant lateral variation of crustal composition is also exhibited among different tectonic units in China continent. The crust of eastern China is much enriched in incompatible elements such as U, Th and K than that of western China; and the crust of orogenic belts is more enrichment than that of platform regions. It is also inferred that the crusts of eastern China and orogenic belts are much felsic than those of western China and platform regions, respectively, derived from the positive correlation between the heat production and SiO2 content of bulk crust. This deduction is consistent with the results derived from the crustal seismic velocity data in China. According to the facts that the lower seismic velocity of China than the average value of global crust, and the higher heat production of China continent compared with global crust composition models published by previous studies, it is deduced that the average composition models of global continent crust by Rudnick and Fountain(1995), Rudnick and Gao(2003), Weaver and Tarney(1984), Shaw et al(1986), and Wedepohl(1995) overestimate the abundance of incompatible elements such as U, Th and K of continental crust.
