云南松具有较广的生态适应性和天然更新能力强的特点,但其天然更新效果是受各种自然因素所支配。在保证种源的条件下,自然因素是影响天然更新的主导因素。从大量调查材料整理分析看:海拨1300米以下地段更新困难,海拨升高,更新效果越好,过高也会影响更新;湿度过大不利于更新;阳坡、半阳坡的云南松天然更新效果优于阴坡;草本植物盖度以30—40%有利于天然更新;林冠下只见云南松幼苗,而不是幼树,不能更新成林;采伐跡地上保留一定的母树,天然更新良好,跡地清理比未清理的效果要好。同时,本文也对云南松人工林作了研究,根据立地条件和生长情况,对云南松人工林划了五个类型。此外还对云南松的演替规律作了初步探讨,为今后发展云南松林提供参考。

According to the investigation of man-made forest of Korean spruce (Picea koraiensis), site index table and numerical site quality table are drawn up in this paper. Combining the practical experience in reforestation of Korean spruce in past 30 years, the classification table of site types is concluded in Suiling forest area. Korean spruce is very adaptive and its ecological amplitude is eurytopic. Most sites are suitable for reforestation of this tree. Korean spruce in these sites with the sealevel below 450m,...

According to the investigation of man-made forest of Korean spruce (Picea koraiensis), site index table and numerical site quality table are drawn up in this paper. Combining the practical experience in reforestation of Korean spruce in past 30 years, the classification table of site types is concluded in Suiling forest area. Korean spruce is very adaptive and its ecological amplitude is eurytopic. Most sites are suitable for reforestation of this tree. Korean spruce in these sites with the sealevel below 450m, gentle slope, medium depth of soil and south,south-west, west and southeast-facing aspects. The north-east, north east and northwest-facing slopes, low level ground which is below 5m and thin soil are bad site factors for affecting the growth of Korean spruce in Suiling forest region.

根据绥棱林区红皮云杉人工林调查材料,编制出立地指数表和立地位质量数量化得分表,结合三十年来绥棱林区红皮云杉更新造林的实践经验归纳出立地类型分类表。认为红皮云杉适应性强,生态幅度大,适宜更新造林的地块多,是发展人工用材林的重要树种。在绥棱林区最适合营造红皮云杉的立地条件是:海拔高小于450米,坡向为半阳坡、阳坡及缓坡以上,中厚土层。软差的立地条件为:阴坡半阴坡、平地(≤5°),薄土层。

The characteristics of black locust forest for firewood were studied. The results are summarized briefly as follows: Black locust grows fast on light soil on hill slopes facing south or half south in semiarid areas. The root system develops horizentally to 3×12m~2. The yield of firewood from the ravine facing south is higher than that from hillsides facing south or other directions after the planting. Firewood yield may increase if the hilldes are closed to facilitate afforestation. As for har- vesting method,...

The characteristics of black locust forest for firewood were studied. The results are summarized briefly as follows: Black locust grows fast on light soil on hill slopes facing south or half south in semiarid areas. The root system develops horizentally to 3×12m~2. The yield of firewood from the ravine facing south is higher than that from hillsides facing south or other directions after the planting. Firewood yield may increase if the hilldes are closed to facilitate afforestation. As for har- vesting method, short interval clear-cutting (at the interval of 2~3years) is recommended. Black locust sprouts easily. When the trees of twelve years are cut, each plant may sprout 9.6 shoots on average. The firewood after cutting has a low water content (29%) and is combustible when moist. Its caloric value is higher than that of poplar or willow trees. The forest can be renewed easily with suckers.

发展薪炭林是尽快解决农村能源有效的途径之一,1983年经对凌源、建平刺槐薪炭林特性的测试表明:刺槐在半干旱地区的阳坡半阳坡薄土层山地生长较快,8年生进入材积速生期,水平根系发达,根幅3×12米~1,产柴量;朝南沟谷地高于半阴半阳坡地;造林后封山育林明显高于不封山育林;采用短周期平茬高于其它采柴方式。刺槐萌芽力强,12年生树平茬后平均每株发萌条9.6根,薪柴含水率较低(湿柴含水29%);易燃,湿柴就可做燃料,热值高于杨、柳树。
