Background

Wisdom cities have both narrow and broad senses. The intelligent city in the narrow sense refers to a city development new mode which is based on the internet of things, enables all functions in the city to be coordinated and operated through the internet of things, is mainly characterized by high integration of intelligent technology, high-end development of intelligent industry and high-efficiency and convenient intelligent service, is essentially more thorough in perception, more extensive in connection, more centralized and more deep in calculation, and is implanted with intelligent genes for the city texture. The smart city in the broad sense is a brand-new city form which aims at 'more scientific development, more efficient management, more harmonious society and better life' and has more perfect perception, cognition, learning, growth, innovation, decision-making, regulation and control capability and behavior consciousness on the basis of a top-down organized information network system.

The concept of the smart city is described according to the current relatively authoritative Chinese smart engineering research meeting: the smart city is a development factor of the global urban and rural integrated development, the urban sustainable development and the national core demand at present, the advanced information technology and the advanced urban management service concept are effectively fused, and the urban infrastructure, the infrastructure environment, the production and life related industries and facilities are subjected to multi-azimuth digital and informationized real-time processing and application by carrying out digital network management on the urban geographic, resource, environment, economy, society and other systems, so that a simpler, efficient and flexible decision support and action tool is provided for urban management and operation, and a more convenient, efficient and flexible innovative operation and service mode is provided for urban public management and service.

The smart city is considered from the perspective of the corresponding social security, consumption, housing, civil service, social security, medical health and health, education, culture, employment, income and the like in the sense and experience of people on the self survival and development conditions; the method is also considered from the management perspective of the smart city in the aspects of reasonable application of homeland resources, layout of city construction, comprehensive city management, public safety management, transportation management, emergency command management, energy conservation and emission reduction management, infrastructure management, social management, community management, enterprise economic transformation, service and the like; but also from the perspective of improving social responsibility in proving civilization, propagating urban image, and maintaining equity responsibility. The construction of smart cities cannot plan and integrate the land inside and outside the cities, and chemical evaluation needs to be carried out on the earth of agricultural land.

Land quality (geochemical evaluation information of agricultural land) is a complex comprehensive attribute of land. The world food and agriculture organization defines land quality as: the land comprehensive property of land utilization mode suitability or continuity is met. The definition of land quality by the Chinese geological survey bureau technical requirement for geochemical assessment of land quality (2008) is as follows: in the context of ecosystems, the ability to maintain biological productivity, preserve environmental quality, and promote the health of animals and plants, and humans, and to maintain or improve atmospheric or water quality. Despite the differences in the defined expressions, the connotations are substantially the same, i.e. the quality of the land is the degree to which the land is suitable for a different use over a period of time or whether it is suitable and the degree to which it is suitable for a certain use. In recent years, with the emphasis and research on soil quality, soil quality indexes have been included in the field of research on soil quality, and have become one of the core problems in soil quality evaluation.

Currently, land quality evaluation work is mainly developed from two angles in China: the method is characterized by comprising the steps of agricultural land grading and land quality geochemistry assessment. During the period of 1999-2009-year, the agricultural land grading work which is carried out and completed by the organization of the national land resource department is the work of carrying out comprehensive investigation and scientific quantification on the agricultural land quality after researching the quantity and ownership of the agricultural land in detail, and emphasizes on the research on the land quality from the perspective of the land production capacity. Since 2008, the geochemistry evaluation work of the land quality developed by the organization of the Chinese geological survey is a new development field for the national economic construction service, and focuses on the research of the land quality from the element perspective. The two works beneficially explore the method and technology for evaluating the land quality and accumulate experience, but the two evaluation methods have advantages and disadvantages respectively, and particularly, each evaluation cannot completely cover the connotation of the land quality. Therefore, research and analysis of the geochemical evaluation information of the land quality of the agricultural land are carried out, which is beneficial to promoting the deepening of land work and the effective utilization of results.

At present, no computer system can effectively set different statistical models based on the data content and format characteristics of business data. In the process of collecting the geochemical evaluation information of the agricultural geological volume, the data result of the evaluation information is a range interval, and the setting of the statistical model is the optimization of the statistical requirements, so that the statistical requirement of the actual query statistical range is met.
