Abstract
Land resources are the basis of human survival and development. Land use benefit is the embodiment of land input-output ability. As an important economic zone and ecological barrier in China, it is important to calculate the land productivity in the Yellow River Basin. Using the center of gravity model and other methods, this study evaluated the land use benefit of the Yellow River Basin from 1995 to 2018 based on the selected indicators of geographic grid-scale and analyzed the regional disparity. The results revealed that the comprehensive benefits, economic benefits, and social benefits of land use were on the rise, but the ecological benefits changed in volatility. Land circulation had a great impact on the change of land use benefits. So reasonable land transfer policy should be particularly significant for land use in the Yellow River Basin. In addition, there were obvious spatial differences and agglomeration effects in land use benefit. The high values of benefits were concentrated in urban groups, which showed that areas with better economic and social development had better land use benefits. To narrow land use benefits’ spatial differences between regions, the less developed areas deserve more preferential policies to improve their economic and social levels. Besides, ecological benefits are generally not high. Thus, the land policy in the Yellow River Basin should take ecological priority as the basic principle while considering economic factors.

The comprehensive land use benefits in the Yellow River Basin increased from 58,329.99 hundred million yuan in 1995 to 63,820.87 hundred million yuan in 2018, with an average increase of 9.41% (Figure 3)

Summary
Land is a complex system consisting of an economy, society, and ecological environment [1]. As a carrier of human activities, land is the most basic natural resource and material base for human survival and development [2]. Effective land use is an important guarantee for sustainable development. Since the reform and opening up, the process of industrialization and urbanization has accelerated, and the contradiction between man and land has intensified. The traditional extension of land use has led to competition among grain production, urbanization, and ecological environment construction on land resources, which has further led to the contradiction between supply and demand of land. China is in a period of rapid socio-economic development, so how to alleviate a series of land problems caused by extensive land abuse is one of the most important prerequisites for achieving high-quality development
