ABSTRACT: This research paper applies the resource-event-agent (REA) framework to model the unique patterns, in both the REA accountability and policy infrastructures, of the mining enterprise domain. A unique resource in this domain is the mineral resource (MinResc), and the acquisition and development of MinResc to prepare it for the mining conversion process requires a unique information acquisition event to create and expand an information resource entity. The physical mineral deposit entity set and the intangible information entity set are thus aggregated into a more abstract and more valuable MinResc resource. The aggregation of a physical resource and an intangible information resource into a more certain and more valuable physical resource is an extension of the REA ontology that has applications in enterprise domains outside of mining.

The important was that studied mineral deposit informations and determine the nature or a segment quantitative investigation, integrated experts’ experience to make sure the weight of dominate mineral factors, and constructed metallogenic prognosis model, and then proceed metallogenic prognosis and mineral resource evaluation use in other regions. To overcome geologic investigation problem which not unity and manifold explanation about geology、geophysics、geochemistry、remote geology at present.

Based on the GIS technology, ETM date of 2000 and CBERS date of 2007 have been used as main data source in this paper.The dynamic degree and transfer matrixof wetland in the study area have been analyzed in order to clear the dynamic change of the wetland in liaohe river water system area in recent years.The results show that the wetland area in liaohe river region during 2000-2007 is obviously the volatility of the whole the increasing trend,the river area and offshore area and coastal wetlands area have been decreased,the areas with decreased river area is mainly distributed in the north of liaohe river region and central region.The areas with increased artificial wetland is mainly distributed in the north centre of liaohe river region. The increase of artificial Wetland and swamp meadow wetland area mainly comes from the transformation of non wetland area,the wetland types and changes of areas also have some correlation among the temperature and precipitation.

The conditions of the occurrence, structure, material composition and controlling factors of Krasnokutsky rare-metal-titanium placer deposit localized in the Miocene sediments of the North-Eastern slope of the Dnieper-Donets basin are investigated. Distinguished lithofacies complexes (alluvial-deltaic, coastal and shallow marine, aeolian) correspond to the Lower (Aquitanian), Middle (Burdigalian) and Upper (Langhian) members of Novopetrovskaya Formation of Miocene. Placer bodies are localized in the littoral marine-coastal complexes of Middle Novopetrovskaya sub-formation. Placerforming process is related to phases of stabilization of the shoreline of the regressive phase of the Sub-Paratetic basin. Main search and forecasting criteria for the identification of promising sites within the Kharkiv-Sumy placer-bearing zone are stabilization of the shoreline in the Middle Novopetrovskaya time simultaneously with development of transverse thereto alluvial-deltaic structures that supply weak mineralized sediments. Also, the deltaic ledge breaking the monotony coastal migration and playing the role of structural-sedimentary traps. The developed digital structural-lithological model of the Krasnokutskoye mineral deposit allows us to offer a set of criteria for comparative evaluation of different placer-bearing areas in order to determine the order of their development. The mineral composition of productive deposits is typical for the placers of the region and for rare-metal-titanium placers as a whole; the increased content of rutile and zircon, which rise the industrial value of placers of this zone, are associated with the influence of crystalline rocks of the Voronezh massif.

Using the University of Notre Dame Global Climate Adaptation Index (ND-GAIN) assessment model for reference, the assessment system and model of agricultural disaster resistance in Henan Province are constructed. The spatial characteristics of agricultural disaster resistance subsystem (vulnerability and preparedness) of 18 cities in Henan Province in 2018 were studied by using GIS technology from six perspctives such as sensitivity, exposure, emergency, management, capacity to analyze. The results show that the agricultural disaster resistance ability of Henan Province is in the middle to lower level, showing the spatial difference pattern of high in the west, low in the southeast and weak in the north and south; the difference of vulnerability index is small, and the difference of preparedness index is large; the difference in the degree of preparedness is the main reason for the obvious difference in the level of agricultural disaster resistance; the development of agricultural disaster resistance in different regions is not balanced, and the disaster resistance in Zhengzhou is the strongest, followed by Luoyang and Sanmenxia, Zhoukou and Zhumadian are less resilient.
