The Study On Malaria Of Near Millennium In Sichuan And Chongqing Areas

There are many articles about Malaria study,which mainly concentrates in Yunnan, Guizhou,Guangxi,Guangdong,Hunan,Hubei,Jiangxi,Fujian provinces where malaria is quite typical.They differentiate concepts of Malaria,or probe into influence pathology,or find out its influence from the angle of disease study and infection medical history.However,the articles about Malaria study in Sichuan and Chongqing areas especially and systematically are extremely limited from the historical geography angle.Moreover,the achievement for research are quite scattered,lacking of systematical understanding.Besides,it is fuzzy for us to understand malaria's concept, and the difference and discrimination between malaria and malaria illness is also insufficiently defined.Based on this,we refer to malaria historical data records about Sichuan and Chongqing areas for the near millennium in this paper,analyze and summarize its distribution and vicissitude process as well as its influence for the society of Sichuan and Chongqing areas.The full text are divided into four chapters:The first chapter is the introduction,which explains the research background,the purpose of this article and the significance,the research methods as well as the key points,difficulties and innovations.Most importantly summarize the current academic condition. In the second chapter,the writer analyzes malaria's historical data about Sichuan and Chongqing areas for the near millennium from the time latitude and the spatial latitude.And we could get the conclusion that malaria existed generally before the Sui and Tang dynasties within the boundaries of Sichuan and Chongqing areas.Along with the unceasing economical development,malaria's sphere of action reduced in Tang dynasty.And within this time they mainly distributed in the eastern Sichuan province, the Three Gorges of the Yangtze River area,southern Sichuan province,western Sichuan's Dadu River,Golden Sand River as well as the majority of western Sichuan province.Since North Song and South Song dynasties,the malaria in eastern Sichuan province area has been weaken and it still existed in southern and south-western Sichuan province.Until Ming and Qing Dynasties,the malaria in Sichuan and Chongqing areas further shrunk,and we couldn't see malaria in many places except in the western Sichuan plateau,western Sichuan's Dadu River and the Golden Sand River. However,the malaria could further retreat from the historical arena along with the economic activities.Based on the conclusion,the writer compared malaria's characteristics in Yunnan,Guizhou and Sichuan provinces.In the third chapter,the writer analyzes the factors which influence malaria' distribution and vicissitudes,discuss the relationship between the malaria vicissitudes with the natural environment,population and the economical development in Sichuan and Chongqing areas.We can get the conclusion that the natural environment is the foundation for malaria' survival,and the climate,the terrain landform,the multiple biological communities all together affect malaria' production,any of them is indispensable.In the historical period,the good forest covering,the sufficient water resource and the clouding and humid environment provided the essential condition for malaria's production in Sichuan area.Human's social and economical activities affect malaria's survival environment.The population unceasing growing,the economy continually developing,the America's high-yield crop's being introduced into our county,the human need to expand the space ceaselessly to enlarge the space for further production.In this way,the space for malaria got smaller and smaller.The human society influenced malaria to a great extent.In the fourth chapter,the writer discusses the influence of malaria to the Sichuan and Chongqing societies from nations' distribution,the economy development,the transportation,the military residence,the bureaucracy system and the cultural mind. Simultaneously,we discuss the question that the Central Culture discriminates against Sichuan and Chongqing societies because of malaria in the historical period.
