This study explores the method of aggregation connectivity planning in high-quality arable land and discusses the significance of arable land connectivity to realize connectivity planning based on arable land quality grade when the Ministry of Land and Resources and Agriculture conduct the designation of permanent farmland. For landscape ecology

this paper discusses the concept of farmland connectivity and analyzes the threshold value between farmland landscape plots. Morphological closing operation is used to achieve spatial connectivity calculation on high-quality arable land. Finally

this paper analyzes the connectivity of Jincheng Town arable land on the basis of this method. Research results show that this method is highly efficient when used to realize connectivity planning based on arable land quality grade. The result matches the local conditions. Compared with other methods

the proposed method can define the land quality grade and threshold value

thus effectively enhance concentration and integrity and retaining the lot edge shape features. This method is helpful for realizing the centralized management of arable land and provides a new method for the study of basic farmland spatial analysis.
