Abstract
Farmland landscape pattern refers to the composition and spatial distribution of landscape elements in a certain spatial range. Farmland landscape pattern formation has natural, historical, cultural and other factors. Since the reform and opening up, China’s rapid socio-economic development, urbanization and a series of social development caused a large number of land occupation, farmland landscape pattern has undergone major changes. Domestic and foreign scholars based on natural geography, landscape ecology, combined with 3S technology, FRAGSTATES landscape index calculation method, from the aspects of landscape evolution process, landscape heterogeneity and diversity and landscape dynamics and driving factors correlation, analyzes the characteristics of regional landscape pattern change, and on this basis, analyzes the influence mechanism and correlation of landscape pattern succession. However, at present, most studies are based on the time axis, focusing on the changes of landscape patterns such as forests, wetland waters and towns. There are relatively few studies on the changes of farmland landscape patterns, and there are relatively few studies on the combination of time and space. Therefore, through the study and analysis of the characteristics of farmland landscape pattern change, the driving factors of landscape pattern change are known, and on this basis, the methods and ways of landscape pattern optimization are studied to provide scientific basis for constructing and optimizing farmland ecosystem, regional ecological network and protecting biodiversity.
Highlights
Landscape is rich in connotation, including explicit content such as farmland, villages and ditches, and implicit content such as farming culture, which is both a natural landscape and an artificial landscape

Summary
Landscape is rich in connotation, including explicit content such as farmland, villages and ditches, and implicit content such as farming culture, which is both a natural landscape and an artificial landscape. Since the reform and opening up, with the rapid development of China ' s economy, the process of urbanization is accelerating, the population is constantly concentrated in urban areas, the contradiction between urban development and agricultural land is prominent, the development of ' spread cake ' caused a lot of waste of land resources, high-quality farmland is occupied, so that the number of land for agricultural production is reduced and the quality of land is decreased, especially because the coordination and protection of resources and ecology are not fully considered in economic development, which makes the regional environment and ecological situation deteriorating. Studying the evolution of farmland landscape pattern can find the evolution law of farmland landscape pattern under the background of rapid social and economic development, and in-depth study of the mechanism of the evolution of farmland landscape pattern under this background, provide opinions and suggestions for the construction and optimization of farmland landscape. Pattern, the construction and optimization of ecological network, the protection of ecological system and the management of agricultural production
