摘　　要：对柳窿桉9号的造林密度及整地生态效应进行研究。结果表明:整地规格对柳窿桉9号林分生长量、抗风性、土壤肥力、林下植被以及水源涵养的影响较小,而且其与造林密度互作对柳窿桉9号林分生长量及抗风性的效应不明显。但密度对林分生长量、抗风性、土壤肥力、林下植被以及水源涵养的影响却较大,是影响产量和抗风性的主要因素。综合林分生长量、抗风性、土壤肥力、林下植被多样性、水源涵养功能以及投资成本,在不严重影响生长量和抗风性的情况下,柳窿桉9号的造林整地挖穴规格以小规格(30 cm×20 cm×20 cm)即可。而造林密度以1110～1320株/hm2较为适宜,不但有利于提高产量、增强抗风性且有利于地力维护。Ecological effect of planting gated in the present work. The results growth, wind resistance, soil fertility, density and woodland preparation in E. saligna x exserta were investishowed that the effect of soil preparation specifications on the stand vegetation and water conservation forest of E. saligna × exserta were very limited, and no obvious interactions with the planting density and the soil preparation specifications were obtained. However, the effects of planting density on stand growth, wind resistance, soil fertility, forest vegetation and water conservation were significant, and played chief roles in wind resistance and yield. Basedon stand growth, wind resistance, soil fertility, forest vegetation diversity, water conservation, investment cost, and on condition that without obviously affect the growth and wind resistance of the plant, the of 1 110 - 1 320 tree per hmz was comparatively appropriate for increase in productivity, wind resistance, and maintenance of soft fertility. planting density enhancement of
