Taking Mengjin County of Henan Province along Yellow River as an example, the morphological characteristics of “non-grain” cultivated land in Mengjin County were systematically identified from the aspects of utilization status and slope distribution, landscape pattern and spatial proximity, cultivation distance and road access, economic gradient and ecological security. The results showed that there was a high overlap between the “non-grain” space and the high-quality agricultural production space, the tendency of non-food utilization of cultivated land was obvious, and the proportion of the adjustment from cultivated land to forest land was too large. Due to the large difference in labor productivity between grain cultivated land and “non-grain” cultivated land, the scale of cultivated land for economic crops is relatively small and scattered, which can not form economies of scale. High-speed transportation shortens farmers-travel time for farming, and the impact of farming distance on the “non-grain” of cultivated land is decreasing. There are a large number of recoverable land near traffic trunk lines, which is closely related to the construction of “corridor landscape project” in recent years. Economic abandoned land accounts for a large proportion in economic gradient areas and farmers in underdeveloped areas have a relatively high degree of dependence on cultivated land. The ecological red line is the rigid bottom line for maintaining regional ecological security. Within the red line, the “rewilding” project should be actively implemented. Combined with the national ecological strategy of the Yellow River, and aiming at building the compound ecological corridor of the Yellow River, the restoration and adjustment schemes of different “non-grain” cultivated land in different locations and types were put forward. The research results can provide reference for the decision-making of land control work in the new period.
