【摘要】：[目的]通过开展绿色农产品土地环境评价,圈定适宜发展绿色农产品的土地范围,为农业部门制定相关决策提供科学依据,实现农业的可持续发展;为进一步申请绿色产地认证和局部区域的土、水环境污染治理提供地球化学依据。[方法]文章基于1:50 000土壤和灌溉水地球化学调查结果,依据《绿色食品产地环境技术条件》(NY/T 391-2000)评价标准,对河北省枣强县开展绿色农产品土地环境评价。[结果]枣强县绝大部分地区单项污染指数小于1,调查区99.66%的面积符合土壤绿色产地要求,仅个别样点表现出超标现象,超标指标主要为汞和镉;78.21%的面积符合灌溉水绿色产地要求,超标指标主要为氟化物和pH。[结论]枣强县具备开发绿色农产品的土地环境潜力,以此为依托,提高农产品附加值,增加农民收入。
[Abstract]:[objective] to define the land range suitable for the development of green agricultural products by carrying out the land environment evaluation of green agricultural products, to provide scientific basis for making relevant decisions in the agricultural sector, and to realize the sustainable development of agriculture. It provides geochemical basis for the application of green origin certification and local soil pollution control. [methods] based on the geochemical investigation results of 1:50 soil and irrigation water and according to NY/T 391-2000, the green agricultural land environment evaluation was carried out in Zaoqiang County, Hebei Province. [results] in most areas of Zaoqiang County, the single pollution index was less than 1. 99.66% of the area in the investigation area was in line with the requirement of green producing area of soil. Only one other spot showed the phenomenon of exceeding the standard, and the main indicators of exceeding the standard were mercury and cadmium. 78.21% of the area met the requirement of green producing area of irrigation water, and the main indicators of exceeding the standard were fluoride and pH.. [conclusion] Zaoqiang County has the land environmental potential to develop green agricultural products, which can improve the added value of agricultural products and increase farmers' income.
