Mollisol land in Jilin province refers to the highquality land with black or dark humus topsoil, good properties and high fertility in the administrative region of the province, specifically including black soil, chernozeme, meadow soil, dark brown soil, brown soil, Baijiang soil and paddy soil. According to this definition, through the superposition analysis of soil types and land type data, the total black land area of Jilin province is 154 600 km2, accounting for 83.3% of the land area of Jilin province. Although Jilin province takes the lead in the protection of mollisol land in China, the problems of “mollisol land becoming less”“mollisol land layer becoming thinner” and “mollisol land becoming infertile” have not been completely controlled. The highvalue utilization mode and brand that use mollisol land to produce highvalue green food and transform resource advantage into economic advantage have not yet formed. It is urgent to carry out research on mollisol land protection and highvalue utilization from the perspective of engineering implementation. It is suggested to carry out engineering projects such as topsoil stripping and utilization of occupied cultivated land by construction projects, construction of highstandard farmland, land fertility improvement of cultivated land, and soil improvement of obstructed cultivated land.
