| 摘 要： | 针对半干旱地区华北落叶松人工林传统密度控制理论的弊端,以32年生华北落叶松人工林为研究对象,通过对土壤水分和养分的测定结果,结合华北落叶松人工林多年的生长表现,提出根据水分和养分环境容量来确定人工林合理密度的新方法,为半干旱地区华北落叶松人工林的可持续经营提供科学依据。

| Abstract: | The experiment is carried out in 32 year old Larix principis-rupprechtii plantation,combining the experimental results of soil water and nutrient.Aiming at the shortness of traditional density control theory of Larix principis-rupprechtii plantation in semi-arid region,the paper brings about the new method on deciding rational plantation density according to the water and fertility capability,which will offer scientific support for the sustainable management of Larix principis-rupprechtii plantation in semi-arid region. |

| Keywords: | semi-arid region Larix principis-rupprechtii plantation rational density |
