In this study, we investigated the plant species composition of three types of abandoned farmland and compared with cultivated farmland in the Chongqing suburban area. We analyzed dynamic changes in species composition and community type as well as trends in plant diversity. The results showed that a total of 99 species, 90 genera, and 39 families were recorded in the spring and autumn. At the second level of the TWINSPAN classification, the cultivated farmland, early abandoned farmland, and late abandoned farmland could all be distinguished. As the number of years since abandonment of the farmland increased, the dominant life form of the plant community gradually transitioned from annual to perennial, and woody plants began to become the dominant species. Plant diversity gradually increased from the early to middle stage of abandonment, but declined during the later stage.

Key words: Chongqing suburban area, abandoned farmland, community investigation, plant diversity
