Three types of soils in central Jiangsu Province was studied using seuential extraction techniques .The results showed that Se concentration of the tested soils is relatively low and the soils derived from sediments of Yangtze River fall in category of that for low-Se soils. Se extracted by 5%K 2S 2O 8-1:1HNO 3 is the predominated Se fraction in these soils, followed by residue Se, making a total contribution of 70%~80% of soil Se.

Three types of soils in central Jiangsu Province was studied using seuential extraction techniques .The results showed that Se concentration of the tested soils is relatively low and the soils derived from sediments of Yangtze River fall in category of that for low-Se soils. Se extracted by 5%K 2S 2O 8-1:1HNO 3 is the predominated Se fraction in these soils, followed by residue Se, making a total contribution of 70%~80% of soil Se. Generally, Se is richer in the topsoil than in the plowpan except for Se exractaed by 2.5mol/L HCl. Water soluble Se concentration is shown to be affected by soil pH, while exchangeable Se is strongly positively related to other fractions except for to water soluble Se. Among the five extractants, only Se extracted by 0.5 mol/L NaHCO 3 is in close relation to shoot Se content. Thus 0.5 mol/L NaHCO 3 can be used as indicator of bio-available Se in these low-Se soils.The sum of Se extracted by 0.25 mol/L KCl and 0.7 mol/L KH 2PO 4 can also be used as indicator of bio-available Se in these low-Se soils.

利用连续浸提技术研究了江苏省低Se地区 3种土壤 (旱作土和太湖地区水稻土 )的Se含量及其形态分布。结果表明 ,3种土壤Se含量均偏低 ,尤其是长江沉积物发育的砂土属于贫Se土壤。对土壤Se形态分析表明有机物 硫化物结合及元素态Se是这些土壤中Se的主要存在形态 ,其次是残渣态 ,二者之和约占土壤总Se含量的 70 %~ 80 %。 5种形态中 ,除盐酸可提态Se趋向于向犁底层富集外 ,其他几种形态均为耕作层接近或高于犁底层。可溶态Se含量受其他形态Se影响较小 ,受土壤 pH值的影响较大 ;可交换态Se则相反 ,与除可溶态Se外的其他形态和土壤全Se含量均有显著正相关关系 ,但与土壤 pH值和土壤有机质无关。 5种有效Se浸提剂中 ,0 5mol/LNaHCO3 浸提的Se与植株含Se量有极显著正相关关系 ,可作为低Se土壤的有效Se浸提剂

In this paper presented are results of a study on quality and pollution of soil environment by monitoring in Hai抋n county,which is located in Central Jiangsu province. The present situation of the soil environment quality and pollution are evaluated by Nemerow integrated index method and standards such as GB/T18407.1-2001, DB32/T343.1-1999 and GB15618-1995. The county has a total of 5.30*104 hm2 of farmland, or 97.7% of the county抯 total, in compliance with the national and local environmental norms...

In this paper presented are results of a study on quality and pollution of soil environment by monitoring in Hai抋n county,which is located in Central Jiangsu province. The present situation of the soil environment quality and pollution are evaluated by Nemerow integrated index method and standards such as GB/T18407.1-2001, DB32/T343.1-1999 and GB15618-1995. The county has a total of 5.30*104 hm2 of farmland, or 97.7% of the county抯 total, in compliance with the national and local environmental norms for production of non-hazard agricultural produce (vegetables, grain, cooking oil); With the standard (GB/T18407.1-2001) as the norm for assessment of the natural background value of the soil, the integrated pollution index of the county is 0.86, falling into the category of 揷lean? About 79.3% of the soil is of Grade One (clean), Factors contributing to the soil pollution are in the order of As>Cr> DDT>Hg>Cu>Pb>Cd> benzene hexachloride, which is mainly the result of some traditional cotton fields having been slightly contaminated with agro-chemicals (DDT, Hg, Arsenic products) and the patterns of land use and pesticide utilization in the 70-80s. In terms of regions amd severity of pollution, the Lixiahe Region > coastal region > the Riverside region. Based on the research results, strategies for utilization and remediation of the soils are brought forth.

通过对苏中典型县海安的土壤环境质量的监测,对照GB/T18407.1-2001《农产品安全质量 无公害蔬菜产地环境要求》、DB32/T343.1-1999《江苏省无公害农产品(食品)产地环境条件要求》及《土壤环境质量标准》(GB15618-1995) 标准,分别采用Nemerow综合指数法进行评价。结果表明: 全县5.30万hm2耕地土壤符合国家及地方无公害农产品(蔬菜、粮油)产地环境要求,占97.7%;以GB/T15618-1995中土壤自然背景值评价,全县综合污染指数为0.86,属尚清洁,其中1级土壤(清洁)占79.3%,土壤中污染因子分担率依次为As>Cr> DDT> Hg>Cu>Pb>Cd>六六六,主要是少部分老棉区受农药(DDT、Hg、As制剂)轻污染,与70~80年代耕地利用方式及农民的用药有密切的关系,总体表现为里下河>沿海>沿江。通过研究提出了土壤利用与修复的规划。

This paper is the first research of miospores from the Lower Carboniferous of a borehole Bin Ⅱ 2 in the Binhai district, North Jiangsu. The present paper records and illustrates 61 species assigned to 38 genera,characterized by Auroraspora macra Schopfites claviger (MC) assemblage. Depending on the analysis of the miospores, the assemblage zone is considered to belong to the Early Tournaisian (late Tn 1b—Tn 3) and can be correlated with the known palynological zones from Longtan, Jurong in southern...

This paper is the first research of miospores from the Lower Carboniferous of a borehole Bin Ⅱ 2 in the Binhai district, North Jiangsu. The present paper records and illustrates 61 species assigned to 38 genera,characterized by Auroraspora macra Schopfites claviger (MC) assemblage. Depending on the analysis of the miospores, the assemblage zone is considered to belong to the Early Tournaisian (late Tn 1b—Tn 3) and can be correlated with the known palynological zones from Longtan, Jurong in southern and Baoying in central Jiangsu Province and the equivalen zones from other countries. This study makes the miospore aseemblage succession of the Lower Carboniferous more continuous from Jiangsu Province and will help to the exploration of resources in this area.

作者首次在苏北滨海地区滨 - 2井中发现了早石炭世的蕨类植物孢子 ,共 38属 6 1种 ,组成 Aurorasporamacra- Schopfites claviger(MC)组合 ,经研究属早石炭早期 (Tn1 b上部— Tn3)。从而补充了整个江苏地区的早石炭世孢子组合序列 ,并与苏南龙潭、句容、苏中的宝应以及国外相应的地层进行了简要对比。为该地区的能源勘探提供了新的地层依据。
