土壤对污染物的缓冲性研究

Buffer Capacity of Soil to Pollutant

外源铜作用下土壤脲酶活性与缓冲性及时间关系的模型研究

Study on Model of Relationships among Soil Urease Activity Buffer and Time by Effect of External Copper Source

江西红壤随着有机质含量的增加，土壤对酸的缓冲性增大，土壤有机质含量与缓冲容量呈正相关。

The acid buffer capacity of Jiangxi Red Soil was increased as the organic matter content increased , and soil organic matter content was positively correlated with buffer capacity .

添加外源铜条件下，土壤脲酶活性是土壤缓冲性及时间2个因素的函数。

Soil urease activity was initially regarded as the function of two factors : buffer and time under the addition of external copper source .

本文阐述了土壤对污染物的缓冲特性的概念，研究土壤对污染物缓冲性的目的和意义、历史、现状和前景，为土壤污染与防治提供了一定的理论依据。

This paper explains the conception and principle of soil buffer capacity for pollutants , reviews its significance , history , present situation , and prospect . The results provide some scientific basis for soil pollution control .

结果表明，有机物料回归土壤能增加土壤孔隙度，降低容重，改善土壤通透性和保水保肥性能，提高土壤的缓冲性。同时提供多种有效养分，培肥土壤，并表现为增加作物产量。

The results indicated that returning organic material to soil can increase soil porosity , reduce soil bulk density , improve soil perviousness and soil retention of water and fertilizer , raise soil buffer capacity , supply multi-nutrients , and increase crops yields .

土壤pH下降可使交换态Cd，Zn，Cu和Pb的比例递增，降低土壤对重金属的缓冲性，增加了重金属对环境影响的风险。

The proportion of exchangeable fraction of Cd , Zn , Cu and Pb in the soils increased and buffer capacity of the soils to the metals decreased with decreasing pH.
