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。
From 2014 to 2017, 8 afforestation / restoration forest models were monitored in Hunan Province. A total of 68 species of pests were detected, including 59 pests, 7 diseases, 2 harmful plants, and pests of moderate or higher hazard level14 Species. The diversity index of pest community in each monitoring forestland ranged from0.360to0.687. The types and hazard of pests detected in the recovery mode were higher than those of new afforestation mode. The pest diversity of new afforestation mode was high, but the degree of harm was more Small, community stability is higher than recovery mode. According to the monitoring situation, some suggestions for afforestation and forest management are put forward.
