摘　　要：近年来,崂山风景区酸雨频率虽然呈降低趋势,但酸沉降对景区生态环境仍存在潜在的威胁。本文基于不同标准,应用简单质量平衡(SMB)法,确定了崂山土壤的酸沉降临界负荷。结果表明:崂山的酸度临界负荷、潜在酸度临界负荷、氮临界负荷、硫临界负荷和地表水酸度临界负荷分别为1.53 keq/(hm2.a),0.32 keq/(hm2.a),0.47 keq/(hm2.a),2.84 keq/(hm2.a),0.44 keq/(hm2.a),确定了风景区生态环境对酸沉降的最大允许负荷,从而为控制酸性物质的排放量提供了理论依据。In recent years,though the occurrence frequency of acid rains in Laoshan scenic spot has presented a downtrend,the acid deposition still have potential threat to the ecological environment of the scenic spot.The critical loads of acid deposition on soils of Laoshan scenic spot were calculated using a simple mass balance method(SMB) based on various standards in this paper.The results showed that the critical loads of acidity,potential acidity,nitrogen,sulfur and surface water were 1.53 keq/(hm^2·a),0.32 keq/(hm^2·a),0.47 keq/(hm^2·a),2.84 keq/(hm^2·a),0.44 keq/(hm^2·a).The maximum permissible loads of the ecological environment in Laoshan scenic area were established and the theoretical basis was provided for the control of emissions of acidic substances.
