Abstract: With the methods of I& and *m index,the vein of spatial patterns of P.densiflora population in Shandong province has been preliminarily studied.The results show that the clump is bigger and the vein is rougher for P.densiflora forest with high administrative age levels than that with low age levels.The clump of artificial forest doesn't show evident patches,and the vein is trifling.The individual distribution pattern of P.densiflora forest with light artificial influence is always random,while that of P.densiflora forest with heavy artificial influence is always even.

Key words: Lepidoptera, egg-hatching, effective accumulated temperature, fecundity.
