摘要
针对丘陵区地形地貌变化显著、地质背景变化大且对地球化学元素含量影响明显的特点,提出了以地质背景分析为基础,以耕地、园地、缓坡地土壤地球化学测量为重点的丘陵区土地质量地球化学调查工作思路。根据赣州地区地质地理特征,具体细化了盆地、谷地、山地的样品布设要求、以地质背景为主要依据的图斑赋值方法、生态地质综合调查与土壤地球化学调查相结合的途径、以无公害富硒集中连片区划定与土地质量建档为核心的成果对接方法等。
In view of the characteristics of obvious changes in topography,geologic background and significant influence on geochemical element content in hilly area,this paper puts forward a method for geochemical investigation of land quality in hilly areas based on geological background analysis,with emphasis on soil geochemical survey of arable land,garden andgentle-slope land.According to the geological and geographical features of Ganzhou,detailed sample method laying in basins,valleys and mountains are,the method of plot-assignment based on geological background,the combination of eco-geological investigation and soil geochemical survey,the method of combining the pollution-free se-enriched concentration and the land quality files as the core.
