Objective This paper analyzed the conditions of newly supplemented and occupied cultivated land in Shenyang from 2020 to 2021 from three dimensions: quantity, quality and ecology. The effectiveness of cultivated land requisition-compensation balance was revealed in the early stage of the "grand requisition-compensation" policy implementation, and provided a reference for the implementation and optimization of the cultivated land "grand requisition-compensation" policy.

Method Based on the cultivated land quality classification data and cultivated land gradation data of Shenyang, this paper adopted statistical analysis and GIS spatial analysis to conduct a comparative analysis on the quantity, quality and ecological conditions of newly increased and reduced cultivated land in Shenyang from 2020 to 2021.

Result In both 2020 and 2021, the area of newly increased cultivated land in Shenyang was less than that of decreased cultivated land, indicating an imbalance in cultivated land requisition-compensation. The newly increased cultivated land in 2020 was superior to reduced cultivated land in soil layer thickness, soil texture, soil organic matter and average cultivated land grade, except for soil pH value. The newly increased cultivated land in 2021 was inferior to decreased cultivated land in soil organic matter, soil pH value and average cultivated land grade, except for soil layer thickness and soil texture. The ecological environment of newly increased cultivated land was superior to that of reduced cultivated land in 2020, but inferior in 2021.

Conclusion During 2020 - 2021, the early stage of the "grand requisition-compensation" policy for cultivated land in Shenyang, the cultivated land requisition-compensation balance was unbalanced in terms of quantity, quality and ecology, and the imbalance further intensified in 2021. The quantity control, quality improvement and ecological construction of cultivated land requisition-compensation should been strengthened in Shenyang, so as to achieve the trinity balance of cultivated land in quantity, quality and ecology.
