摘要：

对小兴安岭凉水国家级自然保护区红松阔叶混交林不同大小林隙及郁闭林分内丘坑复合体特征及分布格局进行了对比和分析.结果表明：大、中、小林隙及郁闭林分中丘坑复合体的丘宽、丘高、丘厚均大于与之对应的坑宽、坑长、坑深.大林隙内丘坑复合体的丘宽、丘高、丘厚、坑宽、坑长、坑深均最大，分别为2.85、0.37、2.00、2.99、2.10、0.39 m；郁闭林分均最小，分别为2.35、0.19、1.60、2.66、1.65、0.21 m.丘的平均体积（1.66 m³）均大于坑的（1.44 m³）.同一大小林隙内绝大多数丘坑复合体之间的特征值差异显著，而郁闭林分内绝大多数丘坑复合体之间的特征值差异不显著.不同大小林隙及郁闭林分丘坑复合体之间的特征值大多差异显著.2012年样地内丘坑复合体大多数特征值显著小于2011年.89.5%和60.5%的丘坑复合体类型为铰链式，形状为半椭圆状，丘坑复合体的分布格局为相对集中.

Abstract: Characteristics of pit and mound complexes in different sizes of forest gaps and closed stands and their distribution patterns were compared and analyzed. The results showed that mean mound width, mound height, mound thickness of all pit and mound complexes were larger than corresponding mean pit length, pit width, pit depth in large, medium and small gaps as well as in closed stands. Mound width, mound height, mound thickness, pit length, pit width, pit depth were the largest in large gap, being 2.85, 0.37, 2.00, 2.99, 2.10, 0.39 m, respectively, and the smallest in closed stands, being 2.35, 0.19, 1.60, 2.66, 1.65, 0.21, respectively. Mean mound volume (1.66 m³) was larger than mean pit volume (1.44 m³). The difference in characteristic values between the most of pit and mound complexes was significant for the same size of forest gap, not significant for closed stands, significant for different sizes of forest gaps and closed stands. Most of characteristic values for pit and mound complexes within the plot in 2012 were significantly less than those in 2011. 89.5% and 60.5% of type and shape of pit and mound complexes were hinge and semiellipse, respectively. Their distribution was relatively centralized.
