对大青山12年生的人工油松林林木蒸腾特征、林地土壤蒸发、土壤含水量、林地坡面径流等指数进行了测试,并对测试数据进行了统计整理,利用降水资源环境容量理论和水量平衡理论对大青山油松林的合理造林密度进行了计算分析。结果表明:合理的造林密度应根据该地区降水资源环境容量来确定,内蒙古大青山阳坡在年平均降水量300~400 mm的降水资源条件下,人工油松林的林分适宜造林密度应为992~2 811株/hm2,相应株行距在3.0 m×3.4 m~1.8 m×2.0 m之间。
對大青山12年生的人工油鬆林林木蒸騰特徵、林地土壤蒸髮、土壤含水量、林地坡麵徑流等指數進行瞭測試,併對測試數據進行瞭統計整理,利用降水資源環境容量理論和水量平衡理論對大青山油鬆林的閤理造林密度進行瞭計算分析。結果錶明:閤理的造林密度應根據該地區降水資源環境容量來確定,內矇古大青山暘坡在年平均降水量300~400 mm的降水資源條件下,人工油鬆林的林分適宜造林密度應為992~2 811株/hm2,相應株行距在3.0 m×3.4 m~1.8 m×2.0 m之間。

In this paper, the transpiration characters of 12 -year Pinus tabulaeformis plantation, soil evaporation, soil moisture and slope runoff have been tested. The reasonable planting density of Pinus tabulaeformis plantation has been calculated by use of the theory of environmental capacity of precipitation resource and water balance. The results show that the reasonable planting density should be determined by the environmental capacity of precipitation resouce in local area. In the sunny slope of Daqing Mountains in Inner Mongolia, under the condition of the mean annual precipitation at 300~ 400 mm, the suitable planting density of Pinus tabulaeformis plantation should be 992 -2 811 plants/hm2, and the corresponding planting space is 3.0 m ×3.4 m - 1.8 m ×2. 0 m.
