Abstract:

[Purpose] Addressing current complicated issues on farmland distribution, utilization, supervision, and inadequate services, this study leverages the advantages of digital technology to develop a digital system of farmland in Zhejiang Province based on spatial-temporal and business data, enhancing the overall intelligence and governance level of farmland-related business monitoring and supervision. [Methods] With the supports of "3S" technology, the system engineering process "V-shaped" model is used to analyze application system requirements and user validation. In this work, a spatiotemporal database for farmland is constructed using PostgreSQL and PostGIS. Map services and advanced spatial data processing and analysis are provided through GeoServer, OGR, and GDAL. Rich user interaction capabilities are implemented using OpenLayers technology and Vue. A comprehensive scenario application system is customized and developed for the "province-city-county-town" levels with triple clients including PC, ZheZhengDing, and ZheLiBan. by combining the government cloud infrastructure, construction of standardized interfaces and services and WebGIS technology. [Results] The functions of our system include visualized supervision of farmland distribution, mangements of grain production functional zones, digitized process management of farmland construction projects, and convenient services of farmland land type queries. The application realizes various online business reporting, progress control, early-warning and decision-making in the processes of grain production functional zone establishment, well-facilitated farmland construction and management. [Conclusion] The system provides efficiently technical management ways for farmland supervision to various levels of farmland-related departments, and can be further promoted and applied in the fields of cultivated land quality improvement management, farmland utilization survey and monitoring, and contracted farmland management.
