摘要
2014~2017年对湖南省8个造林/恢复模式林地进行监测,共监测到有害生物68种,其中虫害59种,病害7种,有害植物2种,危害程度达中度及以上的有害生物14种。各监测林地有害生物群落的多样性指数介于0.360-0.687之间,恢复模式中监测到的有害生物种类与危害程度高于新造林模式,新造林模式的有害生物多样性高,但危害程度较小,群落稳定性高于恢复模式。根据监测情况,对造林和林地管护提出了一些建议。
Forest pests of 8 afforestation patterns in Hunan Province were monitored from 2014 to 2017. The results showed that there were 68 species of pests in total, including 59 species of insect pests, 7 species of diseases,and 2 species of harmful plants. The damage of 14 forest pests were moderate and above. The diversity index of pest community in different afforestation patterns were between 0. 360 to 0. 687. The pests species and damage degree in restoration patterns were higher than those in the reforestation patterns, and the diversity of pests in reforestation patterns were higher, but the damage degree was smaller, thus the community stability was higher than that in restoration patterns. Based on the occurrence of the pests in different afforestation patterns, some suggestions have been put forward for afforestation and forest management.
