帽儿山林场集水区森林景观格局特征的研究

Study On Landscape Pattern Characteristics Of Watershed Forest For Mao'er Mountains Forest Farm

本文以黑龙江省帽儿山林场为研究区域,采用ArcGIS10.0空间分析模块划分该地区集水区的森林,并通过Fragstats3.3对帽儿山林场集水区从斑块水平和斑块类型水平上景观格局进行分析。其中,景观格局指标包括:斑块面积、面积比、斑块数、斑块密度、形状指数、分维度等。研究结果表明:软阔混交林是帽儿山林场集水区主要的森林景观类型,是其森林资源的重要组成成分,其次是硬阔混交林,柞树林,白桦林等,景观资源丰富。该地区景观特征的研究为帽儿山集水区森林景观规划、森林景观生态系统优化提供了理论参考,对改善帽儿山集水区地区森林结构、更好地实现森林空间布局的优化配置和发挥森林的生态功能等方面具有重要意义。

Taken Mao＇ er Mountain as study area, Mao＇ er Mountain watershed forest was divided by the software of spatial analysis model of ArcGISIO. O, and landscape pattern and type were analyzed on Mao＇ er Mountain forest farm watershed by the software of Fragstats3.3. This research mainly from the level of plaque and plaque type level study of the study area, the landscape pattern indexes were used as follows： the plaque area, area ratio, patch number, patch density, shape index and fractal dimension, etc. The research results were showed that the soft broad - leaved mixed forest was Mao＇ er Mountain forest watershed main types of forest landscape, was the impor- tant component of forest resources, followed by the hard broad - leaved mixed forest, Mongolica trees, the birch forest, such as landscape resources. The region landscape characteristic research for Mao＇ er Mountain watershed forest landscape planning, forest landscape ecological system optimization provides the theory reference, to improve the Mao＇ er Mountain forest watershed area structure ; the better to achieve the optimal allocation of forest spatial layout and exert the ecological function of forest is of great significance.
