With the rapid development of social science, it is an irresistible trend for archives management to turn from artificial to information construction. It mainly depends on the degree of archives informatization to judge the archives management level of an enterprise. Archives informatization is based on the original paper archives and changes the contents and existing forms of the archives in line with the principle of information transformation without changing the original content information of the archives. Archives informatization can realize the sharing of archives resources within the enterprise, which is convenient for the human resources department and leaders at all levels to timely access the dynamic archives information of talents in the enterprise.
  Making full use of computer function can improve the efficiency of archives management. The popularization of computer application and the development of network technology provide great convenience for the management of enterprise archives. Using computer and network to build a special archives management platform can not only effectively realize the dynamic management of enterprise archives, improve the management efficiency of enterprise archives, but also save a lot of human and material resources. To ensure the development of archives information construction, it provides a fast and effective archives management function for promoting the overall economic and benefit development of enterprises. For enterprises, the quality of archives management is directly related to the development of enterprises, so the leadership of each enterprise management needs to pay attention to archives management.

在如今社会科学发展迅速的形势下，档案管理由人工化逐步转向档案信息化建设是目前不可阻挡的一个发展趋势，判断企业的档案管理水平，主要是看其档案信息化的程度。档案信息化就是以原纸质的档案为依据，不改变档案原来的内容信息的情况下，对档案本身的内容及档案的存在形式进行符合信息转变原则的改变，使档案信息化，在企业内部，实现档案资源共享，方便企业人力资源部和各个层次的领导及时的查阅动态的本企业人才的档案信息。
       充分利用计算机功能，可提高档案管理效率。计算机应用的普及和网络技术的发展为企业档案的管理提供了很大的方便，利用计算机和网络搭建专门的档案管理平台，不但可以效地实现企业档案的动态管理，提高企业档案的管理效率，还能节省大量的人力及物力。保证档案信息化建设发展，为促进企业的整体经济、效益的发展，提供了快捷有效的档案管理作用。对于企业来说，档案管理的好坏直接关系到了企业的发展，所以，档案管理是需要我们每个企业的管理层的领导去重视的。

Since the 21st century, the development of science and technology promotes the rapid improvement of the level of science and technology. In the field of communication, with the changes of the times, mobile communication technology has developed rapidly from low-level mobile communication technology to high-level modern mobile communication technology after technological innovation and development. At present, with the popularity of the Internet and technological innovation, China is in a period of rapid development of new generation information technology such as Internet, big data, artificial intelligence and regional chain, which promotes the continuous innovation and improvement of modern mobile communication technology.
  At the same time, digital communication has become an important means of information transmission. With the global digitization has become the main trend of today’s society, the continuous emergence of new digital communication equipment, people have become increasingly inseparable from the means of digital communication,and more and more expect to understand and master digital communication technology. It can be predicted that big data and artificial intelligence (AI) will have a profound impact on all aspects of society in the future. In the face of the future wireless communication super heterogeneous network, a variety of communication scenarios, a large number of antenna units, large bandwidth, new service requirements, using big data technology or data-driven and artificial intelligence is undoubtedly the inevitable choice.

Agricultural mechanization is an advanced mode of production, which can effectively improve the rural economy. Protective cultivation is an advanced farming method and a sustainable farming mode. Agricultural mechanization and protective cultivation are interdependent and inseparable. Accelerating both the agricultural mechanization and the development of protective cultivation is an important task in China’s agricultural development.
  Agricultural Mechanization means that the whole process of agricultural production is completed by machinery, which aims to improve labor productivity and land productivity. In recent years, the rapid development of Agricultural Mechanization in China has reduced the labor intensity of farmers, improved the efficiency of agricultural production, solved the problem of rural labor shortage and played a vital role in the rapid development of agriculture in China. However, the rapid development of agricultural mechanization has also brought some problems to the land environment. Agricultural machinery’s deep ploughing and wasteland reclamation have led to serious soil erosion and environmental deterioration. Therefore, it is necessary to popularize protective cultivation technology. Protective cultivation can achieve the goal of no tillage and less tillage by adopting mechanized cultivation. Protective cultivation and agricultural mechanization are interdependent and supplementary to each other. The combination of them can simplify the farming mode, reduce costs, increase economic benefits and achieve sustainable development. Protective cultivation and agricultural mechanization can also effectively reduce agricultural costs and improve food production, which needs to be vigorously promoted in rural areas of China.

农业机械化是一种先进的生产方式，能够有效的提升农村经济。保护性耕作是一种先进的耕作方式，是一种可持续发展的耕作模式。农业机械化和保护性耕作相互依赖，密不可分。加快农业机械化的同时大力开展保护性耕作是我国农业发展的重要任务。
      农业机械化是指农业生产的全过程都使用机械来完成，目的是提高劳动生产率和土地生产率。近年来，我国农业机械化的发展突飞猛进，减轻了农民的劳动强度，提高了农业生产效率，解决了农村劳动力短缺等问题，对我国农业的飞速发展起到了至关重要的作用。但农业机械化迅速发展的同时，也给土地环境带来了问题，机械化深耕深翻、开荒种地导致水土流失严重、环境恶化。为此，需要大力推广保护性耕作技术。保护性耕作通过采用机械化的耕作方式，从而达到免耕、少耕的目的。保护性耕作与农业机械化相符想成、互相依靠，可以简化耕作模式，降低成本，调高经济效益，同时能够起到可持续发展的效果。保护性耕作和农业机械化也能够有效的减低农业成本，提高粮食产量，需要在我国农村地区大力推广。
