祥云新松叶蜂茧主要分布在树冠投影图内层土壤,不同立地条件茧数量分布无差异,内层是种群的最适抽样部位。树冠投影圈内不同方向和层次茧分布显著不同。林分疏密度对茧种群数量和聚集强度是:0.30林地>0.75林地>0.55林地;0.55,0.75和0.30林地小个体群面积是7株时约14m~2,大个体群在30,20,15株时,分别为60,40,30m~2;林间相对茧口密度是0.75林地<0.55林地<0.30林地。 The cocoon of Nelumbo nucifera was mainly distributed in the inner soil of the canopy projection map. There was no difference in the number distribution of cocoon under different site conditions, and the inner layer was the most suitable sampling site for the population. Crown crown in different directions and levels of cocoons significantly different distribution. The population density and aggregative intensity of stand density for cocoon were: 0.30 forestland> 0.75 forestland> 0.55 forestland; 0.55,0.75 and 0.30 forest area were 7 individuals and 14m ~ 2, 60, 40 and 30m ~ 2, respectively. The relative cocoon density in forest was 0.75 forest land <0.55 forest land <0.30 forest land.
