- 摘要:
- 揭示风沙土复配其他固沙材料后的土壤质量变化及改良效应对研发防沙固沙新材料具有重要的指导意义。以乌兰布和沙漠风沙土为对照(CK),采用粉煤灰、脱硫石膏、牛粪3种固沙材料按干质量比15%,25%与风沙土进行复配,研究了不同材料与配比复配土壤对机械组成、养分含量、金属含量的改良效应,运用最小数据集构建、隶属度计算与土壤质量指数计算等方法评价了复配土壤质量。结果表明:(1)不同复配土壤的机械组成均发生了改变,粉粒、粗砂等难蚀、较难蚀颗粒体积分数增加,易蚀的细砂体积分数降低。(2)除石膏复配土壤各养分指标与CK相近外,其余复配土壤有机碳含量较对照提高1.2～10.4倍,牛粪复配土壤在提高养分含量方面显著高于其他材料; 以牛粪和石膏为材料的复配土则分别增加或降低了沙土中的金属含量,而粉煤灰复配土的Cr,As较CK下降。(3)不同复配土对土壤理化性质作用影响各异,粉煤灰在粒径改良方面较优,牛粪在养分提升方面效果显著,石膏在重金属含量降低方面作用明显,粉煤灰石膏混合复配则综合了二者的优势。(4)3种固沙材料均在不同程度上提高了复配土壤的质量,但复配土壤质量仍处于较低水平。综上,不同复配比例组合中,15%粉煤灰复配土壤质量得分指数最高为0.545,对风沙土的改良效果最好,其次为15%脱硫石膏(0.537),15%牛粪(0.506)和25%粉煤灰与脱硫石膏(0.484)复配组合。
- Abstract:
- It is important to reveal the soil quality change and improvement effect of aeolian sand soil combined with other sand-fixing materials for the development of new sand-controlling and sand-fixing materials. The aeolian sand soil in Ulan Buhe Desert was taken as the control(CK), and three sand-fixing materials, flyash, desulfurized gypsum and cow dung, were mixed with aeolian sand soil at dry weight ratios of 15% and 25%, to study the improvement effects of different materials and ratios on mechanical composition, nutrient contents and metal contents. Soil quality was evaluated by minimum data set construction, membership degree calculation and soil quality index calculation. The results show that:(1)the mechanical composition of soils with different combinations changed, and the volume fraction of refractory and refractory particles such as silt and coarse sand increased, while the volume fraction of fine sand that is easy to be eroded decreased;(2)soil organic carbon content of gypsum compound soil was 1.2～10.4 times higher than that of CK, except that the nutrient indexes of gypsum compound soil were similar to that of CK; the nutrient content of cow manure compound soil was significantly higher than those of other materials; the metal contents in sand soils mixed with cow dung and gypsum increased or decreased, respectively, while the Cr and As of flyash mixed soil decreased compared with CK;(3)different combinations of soils had different effects on soil physical and chemical properties; flyash was better in particle size improvement, cow dung had a significant effect on nutrient enhancement, and gypsum had an obvious effect on reducing heavy metal contents; the combination of flyash and gypsum combinef the advantages of the two;(4)the three sand-fixing materials all improved the quality of the mixed soils to varying degrees, but the quality of the mixed soil was still at a low level. In this study, the soil quality score index of 15% fly ash combination is 0.545, and it had the best improvement effect on aeolian sand soil, followed by 15% desulfurized gypsum(0.537), 15% cow dung(0.506)and 25% fly ash and desulfurized gypsum(0.484).
