【摘要】:基于新疆生產(chǎn)建設(shè)兵團(tuán)第二師36團(tuán)的土地質(zhì)量地球化學(xué)調(diào)查數(shù)據(jù),分析了8種土壤元素的含量特征,采用單因子指數(shù)評(píng)價(jià)法和內(nèi)梅羅綜合指數(shù)評(píng)價(jià)法對(duì)土壤環(huán)境質(zhì)量進(jìn)行評(píng)價(jià)。結(jié)果表明,土壤元素含量均值從高到低依次為:ZnCrNiCuPbAsCdHg,且所有元素含量均值均未超過新疆土壤背景值和土壤環(huán)境質(zhì)量一級(jí)標(biāo)準(zhǔn)。新疆生產(chǎn)建設(shè)兵團(tuán)第二師36團(tuán)土壤環(huán)境質(zhì)量良好,優(yōu)于全國(guó)水平。土壤污染評(píng)價(jià)結(jié)果為8種土壤元素含量均超污染起始值,單項(xiàng)污染指數(shù)均值由高到低依次為:PbCrHgZnNiCuAsCd;內(nèi)梅羅綜合污染指數(shù)均值達(dá)到了土壤環(huán)境質(zhì)量評(píng)價(jià)分級(jí)標(biāo)準(zhǔn)Ⅱ級(jí),污染等級(jí)為警戒;不同土地利用類型下的內(nèi)梅羅綜合污染指數(shù)均值由高到低依次為:果園其他林地未利用土地灌木林地旱地。采用因子分析法分析8種土壤元素來源,結(jié)果表明,研究區(qū)8種土壤元素來源受人為活動(dòng)和土壤條件兩個(gè)因子控制。
[Abstract]:Based on the geochemistry survey data of land quality in the 36th regiment of the second Division of Xinjiang production and Construction Corps, the content characteristics of 8 soil elements were analyzed. The soil environmental quality was evaluated by single factor index evaluation method and Nemero comprehensive index evaluation method. The results showed that the average value of soil element content from high to low was ZnCrNiCuPbAsCdHg, and the mean value of all elements content did not exceed the soil background value and the first grade standard of soil environmental quality in Xinjiang. The soil environmental quality of the 36th regiment of the second Division of Xinjiang production and Construction Corps is good, which is superior to the national level. The results of soil pollution evaluation showed that the content of eight soil elements exceeded the initial value of soil pollution, and the average value of single pollution index was PbCrHgZnNiCuAsCd; from high to low. The average value of Nemero comprehensive pollution index reached the grade 鈪,
