The ratios of chemical oxygen demand (COD) to total organic carbon (TOC) in the natural surface coatings, which were developed at different depths of the lake, are measured. The results indicate that there are not significant diversity between the theoretical value (2.67) and the ratios of [COD] to [TOC] in the surface coatings at the water depth range from 0.3 m to 1.3 m, meaning that the organic materials in the surface coatings could be described by measuring the [COD] or [TOC].

The results indicate that there are not significant diversity between the theoretical value (2.67) and the ratios of [COD] to [TOC] in the surface coatings at the water depth range from 0.3 m to 1.3 m, meaning that the organic materials in the surface coatings could be described by measuring the [COD] or [TOC]. The resulted information also showed that the amount of reducible fraction except those consisted of carbon is more than that of aromatic compounds not oxidized by the oxidizing agent of K_2Cr_2O_7.

研究了不同水深培养的生物膜上化学耗氧量[COD]和总有机碳量[TOC]之间的比例关系,结果表明,在0.3—1.3m水深范围内,自然水体生物膜上[COD]与[TOC]比值和理论值(≈2.67)无显著性差异,即COD)或TOC均可以用来表征生物膜上有机质的含量;但随水深的增加,膜上除碳以外的还原性物质相对含量显著增高,且在自然水体生物膜的培养初期,膜上除碳以外的其它还原性组分的含量大于不能被K_2Cr_2O_7氧化的芳香族化合物的含量。

A photooxidative system for degradation of organic dye pollutant RhB as an objective compound was reported under visible irradiation(λ>450 nm) by using Fe~(3+)/H_(2)O_(2) as the Fenton reagent. It was found that,in the system with pH<3.0,visible light irradiation significantly accelerates the degradation process by photosensitive effect.After 160 min the RhB was mineralized with a yield of 71.8%.Bromocresol green reaction spectrophotometrically,spin-trapping electron paramagnetic resonance,UV-Vis spectroscopy,IR and total organic carbon(TOC) measurements were used to detect the photoreaction process.The photocatalytic degradation pathway mainly involves the formation of()~·OH and carboxylie acids are the main intermediate products.

Soil carbon is a significant component of global carbon cycling,the change of land use pattern has a great influence on soil carbon source or sink.Large-scale returning farms to forests on Loess Plateau will necessarily make some important effects on carbon cycling by effecting soil organic carbon content. Based on the field investigation and sampling,as well as national soil investigation data and other soil resource data of the Loess Plateau,soil organic carbon of Loess Plateau was calculated,and the change of soil organic carbon after returning farms to forests was predicted.The content of soil organic carbon of Loess Plateau is lower,the mean soil organic carbon density is 2.49kg/m~2,which is 23.65% of mean level of China,the total soil organic carbon storage is about 1068Tg,that only account for 1.16% of Chinese total soil organic carbon.After implementing the returning farms to forests,soil organic carbon reserves will remarkably increase.Thirty years later,the total soil organic carbon storage of Loess Plateau will increase to 1266.8Tg,rising by 19.21%.

土壤碳是全球碳循环中的重要组成部分,土地利用方式的改变对土壤碳的源和汇具有很大的影响。黄土高原地区进行的大规模退耕还林必然会通过影响土壤有机碳含量对区域碳循环产生重要影响。通过野外调查采样分析,结合使用全国土壤普查及黄土高原地区其它土地资源数据资料,研究计算了黄土高原地区的土壤有机碳量,并对实施退耕还林后土壤碳储量变化进行了预测。黄土高原地区土壤有机碳含量较低,平均土壤有机碳密度为2.49 kg/m2,仅为全国平均土壤有机碳密度的23.65%,土壤有机碳总储量为1 068 Tg,只占全国总有机碳量的1.16%。实施退耕还林后,土壤有机碳储量将明显增加。分步优化实施退耕30年后,黄土高原土壤有机碳储量可增至1 266.8 Tg,有机碳储量总体可增长19.21%。土壤有机碳储量的增加,对区域气候变化及土壤和水环境都将产生影响。
