collection, storage, protection facilities can not meet the archives in the new era, the collection, collation, protection requirements, especially the lag of archive information management. 2, a part-time archivists of training and learning there is still a lack of the knowledge structure of archivists is not comprehensive enough, still can not meet the needs of archives work, in-depth development of the archives work. Measures to solve the Bureau will in future work of archives management to be improved effectively. One is to overcome the shortage of personnel difficulties, concentrate on finishing a good historical archives. The second is to further strengthen archives management training efforts, focusing on the study of archives management, utilization and archives laws and regulations etc. Knowledge to further enhance archival consciousness of cadres and workers and do a good job in the consciousness of the archives work, improve the efficiency in the use of archives. The third is to further improve the level of archives management equipment, with the continuous development of the archives work, overcome the financial resources, lack of material enlarged the file management of equipment investment. In a word, on the basis of insufficient to improve, global will work together, I Bureau of archives management work standardized track to play of archives work in the protection of peoples livelihood, improve the livelihood of the people, the fundamental role of serving the peoples livelihood.XX County Culture and sports and News Publishing Bureau is responsible for the main work is the work of sports culture, press and publication work. In order to further improve my bureau of agriculture related funds management, strengthen regulation of agriculture related funds, improve efficiency in the use of agriculture related funds, effectively improve and enhance the peoples production and living standard of people. According to the (precious Zhengban pass 2015 No. 40) the spirit of the document, I Bureau in a timely manner to global within the scope of agriculture related special funds for the project source, uses, use of self-examination and self correction, self inspection shall be reported to the Sue.A work of self correction, agriculture related funds (a) report of lottery funds of agriculture related funds of self-examination and rectification workThe cat chase chase chase were received by 2013 the lottery public welfare fund project funds use: I Bureau Finance Bureau file your wealth 2013 No. 603 file, your wealth 2014 45 file.
