辽宁省樟子松人工林立地类型的研究

CLASSIFICATION OF THE SITES OF MONGOLIAN SCOTS PINE PLANTATION IN LIAONING PROVINCE

采用生态学和统计分析相结合的方法,对辽宁省樟子松人工林立地类型进行了研究。结果表明:水热条件是樟子松生长的首要条件;土壤条件是樟子松高产稳产的先决条件。通过对气侯、土壤、海拔和樟子松生长等因子进行综合生态分类,把全省划分成6个立地类型:(1)辽东中山丘陵立地类型;(2)辽东半岛沿海丘陵立地类型;(3)中南部低丘平原立地类型;(4)辽西北风沙地立地类型;(5)西部低山丘陵立地类型;(6)辽西走廊沿海丘陵平原立地类型。

Researches on classification of the sites of mongolian scots pine (Pinus sylvestris var. mongolica.) plantation in Liaoning province have been carried out by combining ccology with statistic analysis. The results show that the heat and moisture content is the most important conditions for growth and the soil is the precondition for high and stable yield of mongolian scots pine. Six types of sites are divided by comprehensive analyses on the factors such as climate, soil, elevation and the growth state of mongolian scots pine: (1) site type of middle mountain and hilly area in Eastern of Liaoning province. (2) Site type of coastal hilly area in Liaodong Peninsula. (3) Site type of low hilly plain in Central southern of Liaoning province. (4) Site type of windy and sandy area in Northwestern of Liaoning province. (5) Site type of low mountain and hilly area in Western of Liaoning province. (6) Site type of coastal hilly plain in Liaoxi Corridor.
