摘要：研究林带冬季相结构设计方法是针对我国北方干旱沙区气候和风沙活动特点，为沙区新垦绿洲防护林体系建设服务的。用随机概率法推导曹新孙立木疏透度与疏透度之间的近似数值关系，得知立木疏透度最佳值为３．３；根据生物器官间生长量的相关性提出林带冬季相结构设计方法，测算了新疆杨、沙枣等六个常用防护林树种的设计参数。
Sand drift activity in arid sandy area of North China prevails in Spring when plants in shelter belt are still in Winter facies. To serve the establishment of new osis protective froest system in sandy area, the design method of forest belt structure in this time was studied. With the method of random probability, an approximate numerical relationship between transmissivity( s′ ) and standing tree transmissivity( β ) has been obtained. The optimum value of s′ was 3.3. A simple and convenient method of designing the forest belt structure was formed. Meanwhile, the designing parameters of 6 commonly used tree species were calculated in the paper.
