松梢螟和云杉梢斑螟发生与林分及立地因子的关系
Relationship between the occurrence of Dioryctria rubella and D. schuezeella and stand and site factors
【目的】 研究不同林分及立地因子与松梢螟(Dioryctria rubella)和云杉梢斑螟(Dioryctria schuezeella)幼虫发生的关系,为监测林区2种梢斑螟幼虫的发生提供技术指导。【方法】以宁夏罗山林区油松林松梢螟幼虫、青海云杉林云杉梢斑螟幼虫为研究对象,调查林分密度(x1)、郁闭度(x2)、树高(x3)、枝下高(x4)、冠幅(x5)、胸径(x6)、草本盖度(x7)、灌木丰富度(x8)、灌木多样性指数(x9)等9个林分因子和海拔(x10)、腐殖层厚度(x11)、坡度(x12)、坡向(x13)、坡位(x14)等5个立地因子及相关幼虫虫口密度。利用逐步回归分析筛选影响2种梢斑螟幼虫虫口密度的关键因子,建立关键因子与幼虫虫口密度的线性预测模型;采用偏相关分析、方差分析和多重比较分析关键因子与幼虫虫口密度间的关系。【结果】郁闭度、海拔和坡度是影响松梢螟幼虫发生的关键因子,坡向、胸径和灌木多样性指数是影响云杉梢斑螟幼虫发生的关键因子;建立的松梢螟(y1)和云杉梢斑螟(y2)幼虫虫口密度的线性预测模型分别为y1=208.565-0.075 x10-70.712 x2+0.865 x12和y2=-100.995+17.268 x13+1.499 x6+60.596 x9;海拔和郁闭度与松梢螟幼虫虫口密度呈极显著负相关(P<0.01),坡度与松梢螟幼虫虫口密度呈极显著正相关(P<0.01),坡向、胸径和灌木多样性指数均与云杉梢斑螟幼虫虫口密度呈极显著正相关(P<0.01)。【结论】松梢螟幼虫在林分郁闭度小于0.62、海拔小于2 297 m和坡度大于39.1°的油松林易发生,云杉梢斑螟幼虫在半阴坡、胸径大于24.83 cm和灌木多样性指数大于0.33的青海云杉林易发生,这些林地应作为两类害虫发生监测与防治的重点区域。
【Objective】 This study aims to investigate the relationships between various stand and site factors and the occurrence of Dioryctria rubella and D. schuezeella larvae, so as to provide guidance for monitoring these two shoot moth species in forest areas.【Method】Field investigations were conducted on D. rubella larvae in Pinus tabuliformis forests and D. schuezeella larvae in Picea crassifolia forests in the Luoshan forests area of Ningxia. Nine stand factors were measured: stand density (x1), canopy closure (x2), tree height (x3), height under branch (x4), crown width (x5), DBH (x6), herb cover (x7), shrub richness (x8), and shrub diversity index (x9), along with five site factors: elevation (x10), humus layer thickness (x11), slope (x12), aspect (x13), slope position (x14), and corresponding larval population density. Stepwise regression analysis was used to identify the key factors influencing larval population density and to establish linear prediction models. Partial correlation analysis, analysis of variance(ANOVA), and multiple comparison tests were applied to analyze relationships between key factors and larval population density.【Result】Canopy closure, elevation, and slope were identified as the key factors affecting the occurrence of D. rubella larvae, while aspect, DBH, and shrub diversity index were the key factors affecting the occurrence of D. schuezeella larvae. The linear prediction models for larval population density were established as follows, for D. rubella: y1=208.565-0.075 x10-70.712 x2+0.865 x12, for D.schuezeella: y2=-100.995+17.268 x13+1.499 x6+60.596 x9. Elevation and canopy cover showed highly significant negative correlations with D. rubella larval population density (P<0.01), whereas slope showed a highly significant positive correlation with it(P<0.01). Aspect, DBH and shrub diversity index all exhibited a highly significant positive correlations with D. schuezeella larval population density(P<0.01).【Conclusion】 D. rubella larvae are more likely to occur in P. tabuliformis forests with canopy closure less than 0.62, elevation below 2 297 m, and slope greater than 39.1°. D. schuezeella larvae tend to occur in P. crassifolia forests on semi-shady slopes, with DBH greater than 24.83 cm and shrub diversity index greater than 0.33. These specific forest conditions should be prioritized for pest monitoring and control measures.
