| 中文摘要: |
| 通过对喀斯特地区贵州铝厂周边农作物(白菜、玉米和豆角)、蕨类（贯众）和苔藓(双色真藓)中的Al、Fe、Pb和Ca等金属元素的质量比检测，并按生活区、农田区、工业区统计分析，结果表明：5种植物中Al和Fe的质量比均表现为工业区＞生活区＞农田区，Pb的质量比均表现为生活区＞农田区＞工业区，而植物基质土壤中Ca的质量比受岩溶环境的影响相对其他元素规律性不强。通过对比分析不同植物对Al、Fe、Pb、Ca的富集系数，结果表明：双色真藓、贯众对Al、Fe、Pb的富集能力相对较强，由于贯众数量稀少，无法提供科研实验所需用量，故双色真藓更适合作为该地区环境监测的指示植物。在这5种植物中，只有Fe与Pb之间均呈极显著正相关，二者之间存在协同效应。 |
| 英文摘要: |
| The content of metallic elements Al, Fe，Pb and Ca in crops, ferns and moss around Guizhou Aluminum Factory in karst region were studied. The results showed that Al content in 5 plants from the researched area were in order of industrial area＞residence area＞farmland area. Fe content was in the same order, while Pb in order of residence area＞farmland area＞industrial area. Compared to other elements, Ca content in soil matrix had no strong regularity affected by karst environment. Comparing the enrichment coefficient of Al, Fe, Pb and Ca, the enrichment capability of Bryum dichotomum and Cyrtomium fortunei were relatively strong. Scientific research could not be done because Cyrtomium fortunei was few, Bryum dichotomum was applied to be the indicator plant for regional environmental monitoring. In these five plants, Fe and Pb showed significant positive correlation. There were synergies between Fe and Pb. |
