泰山风景区油松的空间分布地形分异特征研究
Analysis of spatial distribution pattern and topographic differentiation characteristics of Pinus tabulaefor mis forests in Mountain Tai
【摘要】 以泰山林场二类资源调查数据为解译依据,对泰山景区的油松(Pinus tabulaefor mis)林进行了全面的分类,在此基础上利用地学信息图谱方法对泰山景区油松林地形分布进行可视化表达。首次全面地定量地分析了泰山景区油松及其混交林的空间分布的地形分异特征。泰山景区油松纯林、以及油松占优势的混交林(投影)面积共计3 367. 234 4 hm2。其中油松纯林投影面积为2 854.456 3 hm~2,占所有油松林面积的84.77%;其次是油松+赤松混交林,投影面积为250.528 4 hm~2,占所有油松林面积的7.44%。油松纯林主要分布于海拔900~1 400 m,各个坡向的平坡、缓坡和陡坡。坡度大于23°的陡坡和险坡的山地上,随着海拔的升高,油松纯林分布比重有逐渐增大的趋势。油松+赤松混交林在海拔300~1 050 m有分布。
【Abstract】 The research is about the distribution characteristics and topographic differentiation of Pinus tabulaefor mis in Mountain Tai. The pure forest of Pinus tabulaefor mis and its mixed forests scenic spot were classified based on the forest resource inventory data of Mountain Tai. And then we used Geo-informatics graphic methodology to analyze the distribution pattern of Pinus tabulaefor mis forests in Mountain Tai. The main conclusions are as follows. The total Pinus tabulaefor mis forests in Mountain Tai are3 367. 234 4 hm2 of which the pure forest is 2 854. 456 3 hm2,accounting for 84. 77% of the whole Pinus tabulaefor mis forests. The second largest type is the 250. 528 4 hm2 mixed forest of Pinus tabulaefor mis and Pinus densiflora Sieb. et Zucc.,accounting for 7. 44% of the whole Pinus tabulaefor mis forests.The pure forest of Pinus tabulaefor mis mainly distributes in the altitude from 900 m to 1400 m. In the mountainous regions where slopes are greater than 23°,the area proportion of Pinus tabulaefor mis pure forest increases with the increasing altitude. The mixed forest of Pinus tabulaefor mis and Pinus densiflora Sieb. et Zucc. mainly distributes in the altitude from 300 m to 1050 m.
