人工红松(Pinus Koraiensis)幼林易遭风寒害,危害主要发生于春季。1980年春,由于反常的气候条件,使东部山区凡有人工红松幼林的林场,均遭受了不同程度地危害。为深入了解风寒害与立地条件及林分因子之间的关系,于1980年5月至7月进行了调查。现将调查结果整理如下: 一、概况 1、调查区(草河口地区)自然概况草河口地区为本溪县所辖,地处东经123°55′,北纬40°50′,属长白山余脉,境内

Young Pinus Koraiensis young stands are vulnerable to wind damage, mainly in the spring. In the spring of 1980, due to abnormal weather conditions, all the forests in the eastern mountainous areas where man-made Korean pine plantations were handicapped were endangered to varying degrees. In order to gain a better understanding of the relationship between wind damage and site conditions and stand factors, a survey was conducted from May to July 1980. The survey results are summarized as follows: I. General situation 1. Survey area (Caohekou area) Natural overview Caohekou area is under the jurisdiction of Benxi County, located at 123 ° 55’E and 40 ° 50’N, belonging to the remnant of Changbai Mountain.
