摘要樟子松是天然分布面积最大的樟子松。中国)位于内蒙古自治区呼伦贝尔。沙地樟子松是中国北部建设绿色生态屏障的重要树种,其空间分布和动态变化是优化布局的基础。获得了1985~2015年樟子松在研究区的分布情况。结果表明,非生长季更有利于研究区樟子松的分类。樟子松主要分布在南北走向的长条带上,分布面积由1985年的704.84平方公里增加到2015年的1309.74平方公里。鄂温克族自治旗和新巴拉格左旗樟子松的空间变异较大,但不同时期的变化特征不同。面积从1985年到1995年和从2005年到2015年主要增加,但从1995年到2005年减少。1985年与其他年份相比,樟子松的空间格局发生了显著变化,种群整体破碎化程度降低,人类活动逐渐增多。
ABSTRACT The largest natural distribution of Mongolian pine (Pinus sylvestris var. mongolica) in China is in Hulunber, Inner Mongolia autonomous region. The Mongolian pine growing on sandy land has been very important for building green ecological shelters in northern China, and its spatial distribution and dynamic variation were the basis for optimizing the layout. The distribution of Mongolian pine from 1985 to 2015 was obtained in the study area. The results showed that the non-growing season is more conducive to classifying Mongolian pine in the study area. Mongolian pine was mainly distributed in a long north-south-oriented strip, and the distribution area increased from 704.84 km2 in 1985 to 1309.74 km2 in 2015. Large spatial variations in Mongolian pine occurred in Ewenki Autonomous Banner and Xin Barag Left Banner, but the characteristics of the change differed among different time periods. The area mainly increased from 1985 to 1995 and from 2005 to 2015 but decreased from 1995 to 2005. The spatial pattern of Mongolian pine changed significantly between 1985 and the other years, the overall fragmentation of the population decreased and human activity gradually increased.
