基于微生物视角的耕地土壤质量综合评价——以A县土地整治区为例
|
摘要
研究目的:为全面真实地反映耕地土壤质量水平,构建涵盖土壤理化性质、微生物特征以及重金属污染等指标的综合评价模型,以实现土地整治区耕地土壤质量的科学评估。研究方法:最小数据集(MDS)、土壤实验以及DNA高通量测序技术。研究结果:(1)研究区内耕地土壤质量水平不是很高(SQ<0.6),并受到不同程度的重金属污染,尤其是Cr污染(GI>3);(2)土地整治可以显著提高土壤微生物特征指标和土壤有机质含量,并有效降低重金属污染水平;(3)综合整治和传统耕作下的耕地分别具有最高(SQave=0.53)和最低(SQave=0.41)的土壤质量水平。研究结论:从微生物视角构建耕地土壤质量评价模型,有助于提高耕地资源的生态保护意识,可以为耕地综合效益评估和土地整治技术创新提供参考。
In order to comprehensively and accurately reflect the soil quality of cultivated land, it is necessary to construct a comprehensive evaluation model covering the physical and chemical properties of the soil, microbial characteristics and heavy metal pollution to achieve a scientific evaluation on the soil quality of cultivated land in the land consolidation area. The research methods include minimum data set(MDS), soil experiments and DNA high-throughput sequencing technology. The results showed that: 1)the soil quality of cultivated land in the study area was not very high(SQ<0.6),and it was polluted by heavy metals to different degrees, especially Cr(GI>3). 2)Land consolidation significantly improved soil microbial characteristics and soil organic matter content, and effectively reduced heavy metal pollution levels. 3)The cultivated land under comprehensive consolidation and traditional tillage had the highest(SQ_(ave)=0.53) and lowest(SQ_(ave)=0.41) soil quality levels, respectively. It concluded that constructing the soil quality evaluation model from the perspective of microbiology benefits the improving of ecological protection awareness of cultivated land resources,and provides the reference for the comprehensive benefit evaluation on cultivated land and the innovation of land consolidation technology.
