The results indicated that the abandoned farmland was mainly dry land. The overall abandonment rate was not high, but it continued to rise. The abandoned farmland was mainly distributed in Qianyang County, Long County and Fengxiang County. Most of the abandoned farmland was distributed in the medium-high and high nuclear density areas. The high nuclear density areas and the medium-high nuclear density areas were mainly distributed in the hilly area of the northeast of Fengxiang County and the mountains of the north of Qianyang County. The medium nuclear density areas were mainly distributed in Long County, Qianyang County and Fengxiang County. The medium-low density areas were mainly distributed in Long County, and the low density areas were distributed in all counties. There was spatial agglomeration in the abandoned farmland. The low agglomeration areas of cold spots were mainly distributed in Dali County, Pucheng County and Fuping County in the east area. The relatively low agglomeration areas of cold spots were mainly distributed in the middle area. The relatively high agglomeration areas of hot spots were mainly distributed in Fengxing County. The high agglomeration areas of hot spots were mainly distributed in Long County and Qianyang County in the west area. The problem of abandoned farmland in Guanzhong Plain could be solved by vigorously carrying out comprehensive land improvement, formulating relevant policies to help and benefit farmers, and strictly implementing the national policy of cultivated land protection.

The results showed that cultivated land and woodland were the main types of land use, cultivated land and grassland showed a decreasing trend, woodland decreased first and then increased, waters area increased first and then decreased, urban and rural construction land expanded rapidly, and the area of unused land expanded continuously. The dominant position of cultivated land lied in the low terrain niche, woodland centrally located in the middle-high and high terrain niche, water, urban and rural construction land and unused land were mainly distributed in the low terrain niche, and grassland was distributed in all terrain niche, but had no distribution advantage. Stable change type was the main land use change mapping. Continuous change type and repeated change type were mainly the conversion among cultivated land, waters and unused land in the low terrain niche. In the early change type and late change type, the conversion of cultivated land and woodland into urban and rural construction land was mainly located in the middle and low terrain niche, and the conversion of cultivated land to woodland was mainly located in the middle and high terrain niche. Based on the above analysis, the Dongting Lake Ecological Economic Zone was divided into comprehensive functional areas, high quality rural areas and ecological conservation areas, and the corresponding strategies of land use and social and economic development were put forward.
