The Comprehensive Evaluation of Brown Earth Quality in Typical Cultivated Land in Dongling District of Shenyang

论文选取十一项化学及物理指标,对沈阳东陵地区典型耕地棕壤进行质量综合评价。研究区土壤综合质量整体处于中等偏上水平,44.8%区域土壤质量处于高和很高水平,而仍有24.1%的区域土壤质量处于低和很低水平。研究发现供试区土壤养分指标对土壤质量的贡献率大于物理性状指标,影响该地区土壤质量的障碍因子包括速效钾含量、p H、土壤结构等。

Eleven chemical and physical indexes are selected to evaluate the brown earth quality of typical cultivated land in Dongling district of Shenyang. The overall quality of the soil in the study area is above the average. The soil quality of 44.8% of this district is in a high and very high level, but there is still 24.1% of this district with low and very low soil quality. In the experimental district, the research finds that the contribution rate of soil nutrient index to soil quality is greater than that of physical character index, and the factors affecting the soil quality in this area include available potassium content, p H, soil structure and so on.
