摘　　要：选择陕西汉中市、安康市、商州市和淳化县播区1997年飞播油松为对象,1998年-2003年10月,在各播区的多效抗旱驱鼠剂(RPA)处理区和对照区随机抽取50块1m×2m样方调查苗木数量,以有苗样方频度、成苗量和增益指数为指标,采用ANOVA-LSD均值检验法和模型分析法,分析RPA和对照油松有苗样方频度和成苗量差异和动态,评价成苗效果,衡量RPA增益效果。按国标判定,RPA处理区第1年有苗样方频度全优,5年后均不合格;对照区第1年,汉中试验区4优、1良,安康试验区3优、2良,商州试验区1优、4良,淳化试验区1优、2良、2合格,3年后均不合格。飞播后第1年RPA和对照的苗木保存量均评定为优;第5年,RPA为优,而对照区汉中试验区的判定为合格,安康、商州和淳化试验区的为不合格。有苗样方频度和和苗木保存量与飞播年限关系均符合Inverse-模型,且RPA模型值明显大于对照;飞播后第1年至第3年有苗样方频度和和苗木保存量减少量占总减少量的85.0%,不宜进行飞播造林成效评估。RPA对有苗样方增益作用淳化最高,地区整体差异极显著(p=0.005);而对有效苗增益作用相对稳定,地区差异不显著(p=0.395)。Plantations of Pinus tabulaeformis by aerial seeding afforestation in 1997 located in 4 areas in Shaanxi Province were selected as research objects to examine the effectiveness of RPA, including Hanzhong, Ankang, Shangzhou, and Chunhua. Every October from 1998 to 2003, 50 plots, each with an area of 1 m × 2 m were randomly selected in RPA-treated and control compartments, from which indicators such as frequentness of the plots with available seedlings, quantity of the seedlings in the plots, and gained beneficial index were investigated. ANOVA-LSD mean value test method and the model analysis method were used to analyze the differences and dynamics of frequentness of sample plots with available seedling and quantity of available seedling between RPA-treated and control areas. According to the national standard, in RPA test area, the frequentness of sample plots with available seedling in the first year was marked as excellent grade, and those in the fifth year were all unqualified. In Hanzhong, in control area, the frequentness of sample plots with available seedling of 4 plots in the first year were excellent and 1 good, in Ankang 3 were excellent and 2 good, in Shangzhou 1 plot was excellent and 4 good, in Chunhua 1 excellent, 2 good and 2 qualified, all the areas in the third year were not qualified. One year after the aerial seeding, the quantity of available seedling in RAP-treated and control areas was assessed as excellent. Five years after the aerial seeding, the quantity in RPA-treated area was excellent, and in the control area, the quantity in Hanzhong was found to be qualified, Ankang, Shangzhou and Chunhua were found to be un-qualified. Relationship between the frequentness of sample plots with available seedling or the quantity of available seedling and aerial seeding age were consistent with the inverse-model, and the value of RPA model was significantly greater than that of the control. In the period of one to three years after the see- ding seedling, the frequentness of sample plots with availab
