摘　　要：对黑龙江省绥化市北林区设施型黑土土壤中Zn含量分布及来源进行了研究。结果表明,随温室种植年限的增加,土壤总Zn、交换态Zn、碳酸结合态Zn、铁锰氧化态Zn及有机态Zn含量呈逐年增加积累的趋势,其中总Zn含量与种植年限呈极显著正相关,交换态Zn、碳酸结合态Zn、铁锰氧化态Zn及有机态Zn含量与种植年限呈显著正相关,残渣态Zn含量与种植年限不相关;0-80cm剖面含量分析,总Zn、交换态Zn、碳酸结合态Zn、铁锰氧化态Zn及有机态Zn含量均呈逐层下降的趋势,0-60cm降幅较大,60-80cm降幅变缓,残渣态Zn含量变化不显著;同时对设施黑土Zn来源进行探索分析,发现大量施用猪粪、鸡粪等有机肥是Zn的主要来源。We studied content, distribution and sources of Zn element in black soil of facilities in forests of Suihua city, Heilongjiang province. Results indicated that as service life of warm-house increased, contents of total, exchangeable, carbonic acid bound, Fe-Mn oxides bound and organic Zn increased too. Total Zn content were highly significantly positive related to service life, and contents of exchangeable, carbonic acid bound, Fe-Mn oxides bound and organic Zn were significantly positive related to service life. Residual Zn was not related to service life. Analysis results of Zn content of soils from 0-80cm profile indicated that contents of total, exchangeable, carbonic acid bound, Fe-Mn oxides bound and organic Zn decreased as depth increased, with bigger decrease amplitude between 0-60cm, and smaller decrease amplitude between 60-80cm. Residual Zn content changed little. Analysis results of Zn sources indicated that pig and chicken manure were the main sources of Zn element.
