Abstract

The invention discloses a cultivated land quality multi-source heterogeneous data integration method. The method comprises the steps of acquiring cultivated land quality grade data, cultivated land fertility evaluation data and cultivated land quality geochemical evaluation data; converting the cultivated land quality grade data, the cultivated land fertility evaluation data and the cultivated land quality geochemical evaluation data according to a unified database rule, constructing a multi-source heterogeneous data integration model based on a spatial data modeling standard specification GML, and performing unified management through a data manager; and comprehensively evaluating the cultivated land quality data through a contribution rate method. The invention provides a cultivated landquality multi-source heterogeneous data integration model based on GML. By utilizing a multi-source heterogeneous data integration technical process of the model, data such as MapGIS data, ArcGIS data, picture grids and the like are converted into a unified GML data format, so that the data can be conveniently and effectively integrated and shared according to an integration rule in a network environment; the farmland quality data standardization is promoted, so that the data analysis application efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cultivated land quality management, and more specifically relates to a method for integrating multi-source heterogeneous data of cultivated land quality. Background technique [0002] Cultivated land quality management is one of the core contents of land management, and strengthening quality management is an objective requirement for returning to the essential content of land management. Among them, strengthening the management of cultivated land quality is of great significance for improving the productivity of cultivated land and ensuring food security. my country requires adherence to the strictest system of cultivated land protection and the most stringent system of economical land use, and strives to strengthen the protection of the quantity, quality, and ecology of cultivated land, firmly guarding the red line of cultivated land, and promoting the formation of more effective protection, smoother imp...
