摘  要：
[目的]利用高分辨率遥感影像解译结合区域地质调查和土壤地球化学调查,对崇州市开展农业地质背景调查和适宜性评价。[方法]在Delphi专家调查的基础上借助层次分析法(AHP)对崇州市农业地质背景因子进行分析,得出各因子的单一和组合影响权重。选取权重影响较高的多个因子通过GIS手段进行综合分析,最终得出多因子叠加影响下崇州市农业地质背景适宜性评价的等级划分。[结果]崇州市西南部地质背景适宜性评价等级最高,最适宜主导农作物的种植和生长;中部和中北部适宜性评价较高,可作为示范基地扩展建设区域;中部和东部地区具有发展种植主导农作物的潜力。[结论]研究结果为崇州市的农作物种植和粮食基地建设提供了理论依据。

摘  要：
[Objective] Agro-geological background survey and suitability evaluation of Chongzhou area were carried out by combining high-resolution remote-sensing image interpretation with regional geological and soil geochemical surveys.[Method]Based on Delphi experts investigation method,single weight and combinational weight were calculated from the analysis of factors about agro-geological background through the analytic hierarchy process( AHP). Several factors with high weight values were analyzed comprehensively through GIS methods and obtained a rank partition chart of suitability evaluation on agro-geological background under the influence of multiple-factors in Chongzhou City.[Result]The suitability evaluation grade of agro-geological background in the southwest of Chongzhou City was the highest,so it was mostly suitable for planting and growth of main crop. The suitability evaluation grade of agro-geological background in the middle and north-central of Chongzhou City was higher,so it could be as demonstration base extension construction area. The middle and east of Chongzhou City had potential of planting main crops.[Conclusion]The results provide theoretical basis for crop planting and grain base establishment of Chongzhou City.
