【摘要】 本文以土地质量地球化学评估指标体系为研究内容,对内江市威远县镇西镇土地整理区的表层土壤地球化学特征、近地表大气降尘特征、水环境地球化学特征和大宗农产品等方面进行土地质量地球化学分等定级和评估。结果表明,研究区土地质量总体上良好,可划分为211等、212等、221等、222等、311等、321等、312等、322等、411等、412等和421等的级别。同时对研究区内三个自然村的土地质量等级分布现状进行了详述,为当地的土地合理规划利用、提升土地利用价值提供了翔实的地球化学数据依据。更多还原

【Abstract】 In this paper,the geochemical soil quality evaluation system is taken as the study object of the land consolidation area at Zhenxizhen village,Weiyuanxian town,Neijiang city,Sichuan Province to investigate surface soil geochemical characteristics,characteristics of near-surface atmospheric dust,water,environmental geochemistry,and bulk agricultural products and other aspects of geochemical classification and grading of land quality assessment,The results showed that the overall quality of land in the study area are good,and so the land quality can be divided into levels 211、212、221、222、311、321、312、322、411、412 and 421.While the distribution of land quality status of the detailed levels in the three villages of the study area was investigated,thus providing the detailed geochemical data for rational planning for local land use,and enhancement of the value of land use.更多还原
