Abstract: In order to make full use of cultivated land resources and improve the benefits of agricultural industry and accelerate the high-quality development of agricultural industry, this research took Yushe county of Shanxi province as an example to optimize the use efficiency and layout order of agricultural industry space by studying the endowment of cultivated land resources. The status of cultivated land endowment was made clear, including the spatial distribution of cultivated land in dryland, irrigable land, township, and topographic areas. According to the evaluation of cultivated land quality, four combination grade of cultivated land quality were divided into “fourth grade, fifth grade-sixth grade, seventh grade-eighth grade, ninth grade-tenth grade”, and the spatial distribution of cultivated land quality of the total quality of cultivated land and the quality of cultivated land in dryland, irrigated land, towns and topographic parts were studied. Through the analysis of cultivated land quality, the spatial layout of agricultural industry was optimized and adjusted. Three spatial distribution regions of agricultural industry were planned“Priority allocation-high quality cluster”, “rectification and adjustment-characteristic improvement” and “reduced withdrawal-ecological restoration”. The endowment of cultivated land resources restricted the development of agricultural industry, and the quality of cultivated land reflected the productivity of cultivated land. Dividing agricultural industry layout according to the quality of cultivated land could improve the utilization rate of cultivated land and promote the development of agricultural industry in the direction of high quality, high yield and high efficiency.

Key words: cultivated land resources endowment, quality of cultivated land, agricultural industry, space layout
