| After the founding of new China,a large-scale economic construction was carried out.Especially in the 1960 s and 1970 s,various provinces and regions in central and Western China launched a massive "Third line" construction campaign,which has a profound impact on China.In the "Third line" construction,the northwest region is one part of the overall planning,covering Shaanxi,Gansu,Qinghai,Ningxia and Xinjiang.Because the construction and support of the state to Xinjiang is not the same as the other four provinces and regions,the research object of this paper will not include Xinjiang Uygur Autonomous Region,and will focus on the development and construction of the four provinces and regions of Shannxi,Gansu,Qinghai and Ningxia.From the perspective of time line,the construction of "Third line" in Northwest China started generally from 1965 to 1975.After that,the small-scale construction and industrialization development did not make in-depth discussion.The achievements and industrialization construction of "Third line" in Northwest China,which lasted for ten years,after overcoming various difficulties,was a feat.Before we do this,we need to make it clear that although there are still some disputes about the construction of the "Third line",there is no doubt about its achievements and strategic significance.This project is of great significance for promoting the industrialization process of the northwest region and the construction of the national defense forces.Looking at the historical background of the "Third line" period,it is not difficult to find that it has a direct relationship with the domestic and international environment at that time.Generally speaking,it has the following characteristics: first,the political environment around China is poor;second,the industrial layout between the East and the West of China is unbalanced;third,the highest decision-making level of the country has made an extreme response to the overall security situation of the country.The three reasons above are the construction of the "Third line" The main reason for this strategic plan.Therefore,on the basis of historical facts and a large number of information on the development of things,this paper will study the "Third line" construction in Northwest China in terms of historical background,geographical environment,population distribution,natural resources,etc.,reflect the main achievements and industrialization process of the area in the form of data,and discuss the overall planning and implementation of the project From an objective point of view,this paper studies the "Third line" construction and industrialization process in Northwest China.On the whole,various undertakings in Northwest China are booming,which provides the best "naked eye" support for the research foundation of this paper.The "Third line" construction in the northwest not only promotes the overall level of industrialization,but also promotes the economic growth,social integration and the overall development of the country.This major strategic construction has played an important historical role in the regional construction and the progress of various undertakings in Northwest China... |
