The spatial stability of high standard farmland construction refers to the constancy of the quantity structure and spatial layout of farmland under the influence of natural, social, economic and other comprehensive factors during a certain period of time. The stability of the spatial layout of farmland is a prerequisite for the sustainable use of high standard farmland. However, during the construction process, there is an unscientific selection of high standard farmland. Some of the already built high standard farmland is occupied and ecologically damaged before the comprehensive benefit life of the project, resulting in poor spatial stability of farmland. This goes against the concept of high standard farmland construction and causes waste of construction capital. Therefore, in the current context of sustained and rapid socio-economic development, the construction of high standard farmland not only needs to consider the natural endowments of farmland, but also the stability of its external spatial layout will be the focus of research.
