In order to ensure national food security, agricultural product quality safety, and agricultural ecological security, build a long-term mechanism for the protection and improvement of cultivated land quality, maintain the red line of cultivated land quantity and quality, and lay the foundation for sustainable development of food and agriculture. Action Plan for the Protection and Improvement of Arable Land Quality. Jilin Province is an important province of black land in China. In recent years, soil erosion and ecological damage of black land have become more and more serious. The implementation of cultivated land protection is imminent.
In 2018, Jilin Provincial Soil and Fertilizer Station and Zhejiang Topsun Agricultural Technology Co., Ltd. created a large-scale Jilin arable land quality protection system, built a provincial, city, and county triple linkage data platform that aggregated the three arable land quality data of soil, water, and fertilizer. The data of soil, water and fertilizer were collected, processed and analyzed to obtain the macro soil data of the whole province, and the data was analyzed and displayed in a centralized manner.
Construct different thematic content based on different types of soil data, including emergency command of cultivated land, GIS thematic atlas, soil survey monitoring, big data, black land monitoring, and crop fallow. Through detailed display and analysis of different thematic content, it provides the government's scientific decision-making basis. Provide data support for monitoring, management, service, and application of cultivated land quality protection.

The construction of a big data platform for cultivated land quality in Jilin Province has strengthened the data fusion and sharing capabilities of management departments at all levels, improved the data collection, fusion, management, and analysis capabilities of cultivated land quality monitoring and evaluation processes, and implemented the province's "hidden grains on the ground" The strategy of "storing grain in technology" enhances the province's comprehensive grain production capacity. It provides important data support for keeping the strategic bottom line of “basic self-sufficiency in grain and absolute security in rations”.
