应用MapGIS空间分析模块进行土地质量地球化学评估的探讨
摘要
Abstract
Using agricultural geology survey data, This paper discusses how t,o use the MapGIS spatial a-nalysis module for the land quality geochemistry assessment. Taking Land consolidation areas of Tuojiang Village as an example, we select soil nutrient index, soil environmental index, water and atmospheric environment index, large crop safety index for major evaluation indicators. LJ-sing digital terrain model of MapGIS, we draws maps in single factor and single index classification. We use spatial analysis module of area-to-area to analysis in multi-index and multi-factors. Finally the map of geochemical gradation and classification of land quality has been drawn. We use the MapGIS spatial analysis module for the land quality geochemistry assessment. The method is simple and practical. Assessment results basically comply with local actual condition.关键词
