Jiang Youxu, male, Han nationality, is a native of Nanjing, Jiangsu Province. He was born in Shanghai and graduated from Beijing University in 1954.
For a long time, Jiang engaged in comprehensive surveys of natural forests, such as Daxinganling Mountain, west Sichuan, north Yunnan, Tianshan Mountain and Artai Mountain. He supervised orientation research about sub-alpine forests in west Sichuan, tropical forests in the Jianfeng Mountains of Hainan, middle sub-tropical fir artificial forests and mao bamboo forests.
He also conducted large agricultural surveys in Hainan, research on vertical forestry operation in the Northeast natural forest and biodiversity research in warm temperate zones and torrid zones. With a duality method combining sub-building group stratums and ecospecies groups, Jiang set up a unified forest classification systems under the complex natural and geographic conditions of the country.
Jiang also developed a "ring" concept in temperate zones and sub-alpine zones to describe the interrelations between community evolution and development of different formations. He established and directed a long-term orientation research network for the forest ecosystem of China. He also jointly developed a sustainable operation index system for international temperate zones and northern forests, and directed the research about the forest at the national, regional and operational unit levels in China.
