辽宁省固沙造林研究所自1955年在科尔沁沙地东南前哨,辽宁省西北部的章古台,引种樟子松至今已有30余年,有固沙林、种子林(园)等各种试验林1533ha。31年生平均树高9.8m,胸径17.8cm,在沙地上生长良好。樟子松人工林的形成,使沙地人工林内的水分、热量发生了变化。研究其水热变化趋势,对于评价樟子松人工林生态功能、经营好现有林、进一步开展造林,具有重要意义。 1 试验地自然状况和方法试验地设在章古台的大一间房。大一间房
The institute of afforestation in Liaoning Province has been studying the southeastern outpost of Horqin Sandy Land in 1955 and Zhanggutai in the northwest of Liaoning Province. It has been more than 30 years since the introduction of Pinus sylvestris var. The average annual tree height of the 31-year-old is 9.8m and its diameter at breast height is 17.8cm. It grows well in the sand. The formation of Pinus sylvestris var. Mongolica plantation, the sand plantation of water, heat has changed. Studying the trend of water and heat changes is of great significance for evaluating the ecological function of Pinus sylvestris plantation, managing the existing forest and further afforestation. A test site to test the natural conditions and methods set in Zhang Gu Tai Terrace room. A room
