The Evaluation of Wheat Planting Suitability in Zhenping County, Henan Province Based on GIS and RS
Wheat, as an important food crop, has a significant impact on regional and national food security. Nanyang is one of the main wheat production areas, therefore, monitoring the current situation of wheat cultivation and planning planting areas is of great significance. Firstly, Geographic Information System (GIS) technology and the Analytic Hierarchy Process (AHP) were used to partition the land suitability in Zhenping County, and then a suitability level map for wheat planting was created through suitability evaluation indicators. Then, through Remote Sensing (RS) technology, the actual planting situation of wheat in 2021 and the suitability area were analyzed in spatial analysis. The results show that in 2021, the wheat planting area accounted for 53.72% of the total arable land area in the town, and planting in highly suitable areas accounted for 84.73% of the total area. By analyzing the current situation, summarizing the rationality of local agricultural planting, we can provide a scientific basis for future grain crop planting, which is of great significance for optimizing agricultural production layout and improving agricultural production efficiency.
