摘 要:在2个不同立地条件的华山松退化林分内,设置观测实验样地和参照样地,采取抚育间伐、修枝、割灌割藤的综合营林措施,勘测调查退化华山松林木连续4年的树高、胸径、蓄积生长量,分析比对这一综合修复措施对修复退化华山松林分的影响。结果表明:采取该综合修复措施对退化华山松林木胸径、树高、活立木蓄积生长的影响明显,实施该综合修复措施的华山松退化林分每年每公顷比未实施任何修复措施的华山松退化林分蓄积生长量大4.94 m^(3)。在采用该综合修复措施的情况下,因立地条件不一致而导致的对退化华山松林分的影响结果之间差异较小。Observation experimental plots and reference plots in two degraded Pinus armandii Franch forests with different site conditions are set up.Comprehensive forest management measures such as thinning,pruning,and cutting and irrigating vines are adopted.The tree height,diameter at breast height,and volume growth of degraded Pinus armandii Franch forests for four consecutive years are surveyed and investigated,and the impact of this comprehensive restoration measure on the restoration of degraded Pinus armandii Franch forests is analyzed and compared.The results showed that the adoption of this comprehensive restoration measure had a significant impact on the diameter at breast height,height,and volume growth of degraded Pinus armandii Franch forests.The annual volume growth of degraded Pinus armandii Franch forests with this comprehensive restoration measure was 4.94 m^(3) higher per hectare than that of degraded Pinus armandii Franch forests without any restoration measures.In the case of adopting this comprehensive restoration measure,there is a small difference in the impact of different site conditions on the degraded Pinus armandii Franch forest.
