3.1 Creating a Database to Carry out Investigation...
Going on an expedition is the basis for conducting researches on the conservation and utilization of industrial heritage.At that time,there were more than 2 000 third-front enterprises across the country.What about now?How many third-front industrial heritages are left nowadays?The state has not set up a specialized agency to conduct a comprehensive and systematic investigation on the number and the preservation status of third-front enterprises'sites and thirdfront industrial heritage.[7]Some third-front construction researchers have conducted regional surveys about third-front enterprise heritage.However,due to certain conditions,such surveys are not systemic and comprehensive.We should comprehensively collect and record the basic information of the third-front industrial heritage.In addition to keeping the archives and other relevant documents,as well as physical materials,we should conduct oral interviews with relevant personnel of the third-front enterprises,and conduct on-site investigations and take photographs of the third-front industrial architectural heritage.Establishing database of pictures and texts is also necessary because it can not only provide basic data for third-front industrial heritage analysis,but also facilitate future researches.(https://www.daowen.com)
