【摘要】：[目的]通過開展綠色農(nóng)產(chǎn)品土地環(huán)境評價,圈定適宜發(fā)展綠色農(nóng)產(chǎn)品的土地范圍,為農(nóng)業(yè)部門制定相關(guān)決策提供科學(xué)依據(jù),實現(xiàn)農(nóng)業(yè)的可持續(xù)發(fā)展;為進(jìn)一步申請綠色產(chǎn)地認(rèn)證和局部區(qū)域的土、水環(huán)境污染治理提供地球化學(xué)依據(jù)。[方法]文章基于1:50 000土壤和灌溉水地球化學(xué)調(diào)查結(jié)果,依據(jù)《綠色食品產(chǎn)地環(huán)境技術(shù)條件》(NY/T 391-2000)評價標(biāo)準(zhǔn),對河北省棗強縣開展綠色農(nóng)產(chǎn)品土地環(huán)境評價。[結(jié)果]棗強縣絕大部分地區(qū)單項污染指數(shù)小于1,調(diào)查區(qū)99.66%的面積符合土壤綠色產(chǎn)地要求,僅個別樣點表現(xiàn)出超標(biāo)現(xiàn)象,超標(biāo)指標(biāo)主要為汞和鎘;78.21%的面積符合灌溉水綠色產(chǎn)地要求,超標(biāo)指標(biāo)主要為氟化物和pH。[結(jié)論]棗強縣具備開發(fā)綠色農(nóng)產(chǎn)品的土地環(huán)境潛力,以此為依托,提高農(nóng)產(chǎn)品附加值,增加農(nóng)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.
