	Abstract:In this paper, based on the remote sensing image of Landsat7 TM/ETM, the ArcGIS10.3 software is used to interpret the land use in Yantai 2015, and the Land Use Remote sensing classification of China\'s coastal zone is classified as the basis, then the land use status of Yaitai 2015 is obtained. The paper analyzes the matching relationship between land use status and economic development by combining the state of economic development, relevant literature and related Yearbook. The following conclusions are drawn: ①The main land utilization type of Yantai 2015 are arable land, woodland, garden and construction sites, while the unused land area is very small. ②The protection of coastal wetlands in Yantai has been better in recent ten years, and the methods of inshore aquaculture and other utilization have increased. ③ The development and policy of Yantai economy is the main driving force of the change of land use mode. ④ The Yantai city belongs to the retarded type of land use benefit, and the development degree of barely coordinating can′t provide a big impetus for economic development.

	Abstract:In this paper introduces three aspects of content: cause of earthquake; magnetic anomaly analysis before the earthquake; the relationship of magnetic anomaly and earthquake magnitude. Through the research of WenChuan earthquake, introduce seismo-magnetic anomaly detailedly. This paper also introduces the application of wavelet analysis in interference rejection and Date Processing, provides effective method for seismo-magnetic observation.

	3. Biodegradation of hydrocarbon in Dongsheng sandstone-hosted uranium deposit，North China

	Abstract:Organic geochemistry were studied for the ores and altered, unaltered host sandstones at the Dongsheng sandstone-hosted uranium deposit in the Ordos Basin, North China. Interlayer alteration of the host sandstone in the Dongsheng deposit is different from one in the other sandstone-hosted uranium deposits of China and may be divided into four geochemical zones, i.e., the unaltered grey host sandstone in the reducing zone, light purple-red host sandstone in the oxidized zone, grey-green sandstone in the oxidized zone and mineralized grey sandstone (ore) in the oxic-anoxic transition zone. Uranium ore bodies occur, as tabular (mostly) and roll-front in shape, within the grey sandstone of unaltered reducing zone near oxic-anoxic transition zone for industrial mineralization and within the grey-green sandstone of oxic-anoxic transition zone for unindustrial mineralization. The gas chromatograms of total saturated hydrocarbons show unimodal distributions and the normal alkanes C17 to C35 with an odd carbon number preference and maxima concentrate around C25–29, which are typical for terrestrial high plant. The organic matter in the unaltered grey host sandstone and the light purple-red host sandstone in the oxidized zone is immature, while the organic matter in the re-reduced grey-green host sandstone and mineralized grey sandstone (ore) has a maturity equivalent to the main stage of petroleum generation (catagenesis). Evidence of hydrocarbon biodegradation associated with uranium mineralization was found. The biodegradation is a bacterial degradation which can be considered as a catalyst for the reduction of uranium. Occurrence of biodegraded migrated organic matter can be considered as a favourable criterion for the settling of uranium mineralization in searching and prospecting for uranium deposit. Finally, a two-stage genetic model of the uranium deposit based on the mixing of three fluids (brine, meteoric water and oil) has been developed.

	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: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.
