The research to evaluate the northeastern region of China during the "Manchukuo" period from the relationship with the postwar period has only recently began. Conventional research has been paying attention mainly to the negative heritage aspect of "Manchukuo". However, regarding the agriculture and forestry in the region, there are continuous aspects between pre and post war, not only discontinuities. Historical analysis of agriculture and forest industry of “Manchukuo” needs to be promoted in a multilateral and uniform manner with regard to the relationship with the postwar era, both inheritance and non - succession aspects.
Many of the forestry systems of "Manchukuo" are selected and inherited principally by New China, and influence the current situation of forest resources in the eastern part of northeast China and inner Mongolia.
In order to conduct various forestry tests, the section of experimental forest, bureau of forestry, division of agricultural development, Manchukuo, selected and established 15 experimental forests in areas which were important or requiring urgent afforestation, from 1938 to 1945; Zhanggutai, Longhua, Xinglong, Cullen, Harlan aershan, Huiyin guo ren, Muir he, San he, Qiling, Wei he, Gudong he, Jing yue tan, Gaiping, Panshan. After the liberation, these experimental forests were taken over by China, while some were abolished, and some were strengthened and continued.
For example, in the Zhanggutai experimental forest, which was established for windbreak forests to prevent the spread of the Horchin Desert and to protect the Shenyang city from the wind sand, “Experimental forest of institute of preventing desertification, Liaoning province" which is one of four state-lavel desertification prevention research institutes in China, was set up soon after the war, and continued planting, resulting in the formation of a windbreak forest representing the northeast of China. For this reason, this area has been regarded as "a sanctuary for greening" as one of the few greening successes in desertified China, it has been frequently converted into a TV drama and has become a greening model throughout the country. Also, Heilongjiang Province's "Dailing experimental forest" was especially reorganized as "Bureau of Dailing experiment forestry" after the war, gathered excellent forest engineers from all over the country to plant excellent forests, as a model forestry bureau, has been sending out excellent forest engineers.
Thus, the experimental forest system of "Manchukuo" has been inherited in a different form, leaving a considerable influence on forestry in northeast China and China as a whole.
Therefore, by investigating the present condition of these former "Manchukuo" experimental forest sites and examining what type of forestry policy was taken in these areas after liberation, I want to clarify how New China independently selected and inherited the heritage of "Manchukuo", then, examine the discontinuity and continuity from "Manchukuo" to New China, from the specific case of experimental forest disposal.
