What is Implementing land evaluation and site assessment (LESA system) in farmland protection: A case‐study in northeastern China about?

## Abstract Farmland evaluation has become a major topic in farmland protection research. Due to the lack of reasonable and scientifically reliable evaluation methods for farmland protection, the farmland of quality and covering a wide area are at high risk of degradation and destruction in China due mainly to rapid industrialization and urbanization. The land evaluation and site assessment (LESA) system has been successfully applied to protect important farmland globally. To better understand and testify the flexibility and suitability of the LESA system for farmland protection in different geomorphic regions in China, we investigated the delineation of basic farmland by applying and testing the LESA system in Liaoning Province of China. In this study, the LESA system was constructed and comprehensively evaluated through the land evaluation (LE) and site assessment (SA) subsystems; soil conditions suitable for agriculture and site conditions feasible for other land uses were selected in the LE and SA subsystems, respectively. The results demonstrated that the ratios of the LE and SA subsystems were 6:4, 5:5, and 4:6 in the middle plain area (MPA), eastern mountainous area (EMA), a
