摘要:
      土壤、大气、水和农产品质量共同构成土地生态质量的内涵。通过慈溪市基本农田质量调查试点项目,开展了高精度土壤地球化学调查和农产品、灌溉水、大气质量调查,建立了土地生态质量评估模型。以土壤地球化学质量评估为基础,进行了大气、水、农产品综合质量评估,以及慈溪市农用地土地生态质量评价。评价显示,慈溪市农用地土地生态质量绝大部分优良,只有局部如城市周边等地存在生态风险。试点成果为浙江省国土资源特别是基本农田的数量、质量和生态管护并重的精细化管理提供了示范和依据。

Abstract:
      Soil, air, water and agricultural products quality constitute the contents of land ecological quality. Through pilot projects of basic farmland quality survey in Cixi City, the authors carried out soil geochemical survey of high precision in lights of agricultural products, irrigation water and air quality, and established the ecological quality of land evaluation model. Based on soil geochemical quality evaluation, the authors conducted comprehensive quality assessment on air, water and agricultural products, ecological quality of agricultural land in Cixi City. The evaluation showed most of the land quality was fine in Cixi City, some areas like the surroundings of the city existed ecological risks. The above study results provided basic data in terms of quantity, quality and ecological management and protection of the refinement of both model and basis for management.
Keywords:Land ecological quality  Geochemical assessment  Atmosphere  Irrigation water  Agricultural products quality  Cixi, Zhejiang
