Geophysical-Geological Interpretation and Deep-Seated Gold Deposit Prospecting in Sanshandong-Jiaojia Area, Eastern shandong province, China

Acta Geologica Sinica(English Edition) 2012年第3期86卷 640-652页

作者： SONG Mingchun WAN Guopu CAO Chunguo HE Chunyan shandong Provincial Bureau of Geology and Mineral Resources Jinan 250013China shandong Institute of Geophysical and Geochemical Exploration Jinan 250013China

Integrated gravitational, electrical-magnetic surveys and data processing carried out in the Sanshandao-Jiaojia area, Eastern shandong province, northeast China, aim to illuminate the geological characteristics of this shallow-covered area and delineate deep-seated gold prospecting targets. In this region, altogether 12 faults exert critical control on distribution of three types of Early Precambrian metamorphic rock series, i.e. those in the metamorphic rock area, in the granitic rock area underlying the metamorphic rock, and in the remnant metamorphic rock area in granites, respectively. Additionally, the faults have major effects on distribution of four Mesozoic Linglong rock bodies of granite, i.e. the Cangshang, Liangguo, Zhuqiao-Miaojia and Jincheng granites. The Sanshandao and Jiaojia Faults are two well-known regional ore-controlling faults; they have opposite dip direction, and intersect at a depth of 4500 m. Fracture alteration zones have striking geophysical differences relative to the surrounding county rocks. The two faults extend down along dip direction in a gentle wave form, and appear at some steps with different dips. These steps comprise favorable gold prospecting areas, consistent with a step metallogenic model. Six deep-seated gold-prospecting targets are delineated, i.e. Jincheng-Qianchenjia, Xiaoxizhuang-Zhaoxian, Xiyou-Wujiazhuangzi, Xiangyangling-Xinlicun, Panjiawuzi and Miaojia-Pinglidian.

How land-cover has been changed by human use over the last 300 years is oneof the five overarching questions guiding the Land-use/Cover Change (LUCC) Science/Research *** has variety of historical documents providing unique data superiority. So the characteristicsof farmland area in shandong province during the Qing Dynasty (1644-1911) are summarized firstly: 1)the rising trend of farmland area was striking; 2) farmland area had remarkable fluctuation; 3)farmland area per capita decreased dramatically; 4) wasteland reclamation index increased ***, the driving forces of farmland area change are analyzed. It is concluded that natural andhuman factors are jointly influential. Among the driving forces, human dimensions are the mainfactors of farmland area change, which direct the general tendency of the changes mentioned *** the natural factors influence the stability of farmland area as well. Variation of the naturalfactors would act as the major contributory factor to farmland area change during years or periodsof abrupt climatic changes, or during the intensive occurring periods of natural hazards. Besides,the passive aspects of human factors, such as war chaos also influenced the fluctuation of thefarmland area. This research indicates that it is feasible to study the land-use/cover change byChinese historical literatures, which has huge potential to provide a comprehensive picture of thegrowing dominance of human land-use and land-cover patterns that can be used in many global changeresearch projects.

Objective： Population-based cancer registration data in 2012 from all available cancer registries in shandong province were collected by shandong Center for Disease Control and Prevention （SDCDC）. SDCDC estimated the numbers of new cancer eases and cancer deaths in shandong province with compiled cancer incidence and mortality rates. Methods： In 2015, there were 21 cancer registries submitted data of cancer incidence and deaths occurred in 2012. All the data were checked and evaluated based on the National Central Cancer Registry （NCCR） criteria of data quality. Qualified data from 15 registries were used for cancer statisties analysis as provincial estimation. The pooled data were stratified by area （urban/rural）, gender, age group （0, 1-4, 5-9, 10-14, ..., 85＋ years） and cancer type. New cancer cases and deaths were estimated using age-specific rates and corresponding provincial population in 2012. The Chinese census data in 2000 and Segi＇s population were applied for age-standardized rates. All the rates were expressed per 100,000 person-year. Results： Qualified 15 cancer registries （4 urban and 11 rural registries） covered 17,189,988 populations （7,486,039 in urban and 9,703,949 in rural areas）. The percentage of cases morphologically verified （MV%） and death certificate-only cases （DCO%） were 66.12% and 2.93%, respectively, and the mortality to incidence rate ratio （M/I） was 0.60. A total of 253,060 new cancer cases and 157,750 cancer deaths were estimated in shandong province in 2012. The incidence rate was 263.86/100,000 （303.29/100,000 in males, 223.23/100,000 in females）, the age-standardized incidence rates by Chinese standard population （ASIRC） and by world standard population （ASIRW） were 192.42/100,000 and 189.50/100,000 with the cumulative incidence rate （0-74 years old） of 22.07%. The cancer incidence, ASIRC and ASIRW in urban areas were 267.64/100,000, 195.27/100,000 and 192.02/100,000 compared to 262.32/100,000, 191.26/100,000 and 188.48/100,000 in

The diversity of soils derived from different parent materials and developed on different terrains inshandong province, China, was analyzed with the theory of pedodiversity using a 1:1000000 scale soilsand terrain digital database (SOTER) of shandong province in a geographical information system (GIS)environment. Diversity index of soils derived from different parent materials followed the sequence of igneousrock ＞ sedimentary rock ＞ metamorphic rock ＞ unconsolidated material. Diversity index of soils developedon different terrains followed the sequence of plain ＞ medium-gradient mountain ＞ medium-gradient hill＞ valley floor ＞ medium-gradient escarpment zone ＞ depression ＞ high-gradient mountain. Abundancedistributions of these soil groups matched the logarithmic normal distributions.

Cultural Landscape Evolution of Traditional Agricultural Villages in North China——Case of Qianzhai Village in shandong province

引用

Chinese Geographical Science 2008年第4期18卷 308-315页

作者： FANG Yangang LIU Jisheng College of Urban and Environment Sciences Northeast Normal University Changchun 130024 China

Agricultural village is an important rural type in China. The evolution process and mechanism of its cultural landscape are different from those of the industrialized village. The paper focuses this theme by a case study of Qianzhai Village of Qufu City, Shangdong province. In the case of Qianzhai Village, the evolution of its settlement has experienced three stages: mechanical expansion, sprawling expansion and hollowing, and recentralization. The land- scape evolution of residents' houses has undergone three phases: traditional quadrangle house, one-storied house and multistoried house. The evolution of its land use has experienced three stages: circled stratification, fragment and intensive use, and concentration and extensive use. We can see that the main driving factors of cultural landscape evolu- tion of agricultural village are the changes of rural population, society, economy and culture, which are influenced by the change of urban-rural relation, the national modernization process and economic development, the reform of family planning and land system, and the changes in governmental policies. In the future, the modernization, ecological trend, and individualization for residents' houses of agricultural villages in China will develop step by step. The recentralization of settlement and the scaled, sustainable, intensive land use are likely to be the trends of agricultural villages in China.
