摘要
土地质量地球化学评价数据库是以土壤地球化学调查为主,同时开展大气干(湿)沉降物、灌溉水、化肥及农作物等介质的地球化学调查数据和分析数据资料为基础,利用MapGIS软件管理编制成果图件;利用Access数据库管理规范成果数据;利用中国地调局发展研究中心下发的《土地质量地球化学调查与评价数据录入子系统》将数据资料数字化,从而建立评价数据库。数据库内容包括区域地理地质、地形地貌、土壤类型及土地利用等基础空间数据库;包括采样介质的工作区采样布置、单元素地球化学图、土壤元素分级图及大气环境、灌溉水环境、土壤质量、土地质量综合等级图为核心的空间评价数据库;包括土地规划图、特色农产品种植规划建议图、施肥建议图等各种成果图件。数据库实现了对样品及相应的众多的化验分析数据的科学有效的管理,便于数据的统一保存、分析和使用,为评价区土地质量地球化学调查评价和总体综合研究提供了基础资料,为促进农业经济规划调整,现代绿色农业发展和优化、特色土地资源开发与利用提供重要依据。
Based on soil geochemical investigation,analysis data of atmospheric dry(wet)sediment,irrigation water,fertilizer,crops and other media,by using MapGIS management to make the achievement map,using access management to standardize the achievement data,using the"Data entry subsystem of geochemical survey and evaluation of land quality"issued by the development research center of China Geological Survey Bureau to digitize datas,and establishes the evaluation database.The contents of the database include basic spatial databases,such as regional geography and geology,topography and geomorphology,soil types and land use;spatial evaluation database,such as sampling layout,single element geochemical map,soil element classification map and comprehensive grade map of atmospheric environment;irrigation water environment,soil quality and land quality as the core of sampling medium;various achievement maps,including land planning map,planting plan suggestion map and fertilization suggestion map of agricultural products.The database can realize the scientific and effective management of the samples and the corresponding numerous laboratory analysis data,facilitates the unified storage,analysis and use of the data,provide the basic data for the geochemical investigation and evaluation of the land quality in the evaluation area and the overall comprehensive research,provide the basis for promoting the adjustment of the agricultural economic planning,the development of modern green agriculture and the development and utilization of land resources with high quality.
