1. Ensure food security: cultivated land is the basis of food production. Without enough arable land, food production cannot be guaranteed. From the perspective of food security, farmland protection audit can ensure that farmland is not abused or used for other purposes, thus ensuring the stability and sustainability of food production and safeguarding national food security.
2. Promote the rational allocation of land resources: farmland protection audit can evaluate the utilization of land resources, find the waste of land resources, and put forward optimization suggestions, so that land resources can be more rationally allocated and utilized and land use efficiency can be improved.
3. Promoting rural economic development: Through farmland protection audit, we can understand the actual situation of rural economic development and provide reference for formulating rural economic development policies. At the same time, farmland protection audit can also promote farmers' participation consciousness and self-management ability, and promote the sustainable development of rural economy.
