Qiang Wu · Journal of China University of Mining and Technology · 2001
Based on the MapInfo, an agricultural land suitability assessment system (ALSAS) for Qiuxian County in Hebei Province was developed, which can deal with all kinds of data timely. On the basis of the established assessment model, the ALSAS can complete single or multi factor assessment of land suitability, so the class of land suitability can be attained. It has other functions related to land assessment such as analysis, statistic, and land plan. Data management, land assessment, and office automation are integrated into the ALSAS. This system is highly praised by local land management departments because it has effectively accelerated the standardization,systematization and modernization of their routine work. From the practice of developing the ALSAS, its implementation process and key technology were discussed.
