摘要
以遥感影像和野外调研数据为基础数据,基于DEM数字高程数据提取双子山国家森林公园地形因子,运用GIS、RS技术对森林景观格局沿地形因子的分异特征进行分析,以期揭示双子山国家森林公园景观格局地形分异特征规律,为景观格局优化、森林合理经营与保护提供科学依据。结果表明:双子山国家森林公园景观格局随地形因子变化的分异特征显著。各森林景观主要分布在海拔200~400m和坡度为6°~15°的缓坡地区,针阔混交林与硬阔叶混交林优势分布明显,分布面积较大,但同时侵害了其它景观类型的生长环境;地势较低区域受人类干扰程度较大,景观分布面积相对较少,生物多样性不高,地势较高区域受自然环境原因影响,景观分布面积也相对不高。
Based on remote sensing images and field survey data as the basic data,the topographic factors of Shuangzi Mountain National Forest Park were extracted based on DEM digital elevation data,and the GIS and RS techniques were used,the different features of the forest landscape pattern along topographic factors were analyzed,in order to reveal Shuangzi Mountain National Forest.The characteristics of the landscape pattern of the park landscape pattern provided scientific basis for the optimization of landscape pattern and rational management and protection of forests.The results showed that the landscape pattern of Shuangzi Mountain National Forest Park varies significantly with topographic factors.The forest landscapes were mainly distributed in gentle slopes with an elevation of 200-400 mand a slope of 6-15 degrees.Mixed forests of mixed coniferous and broad-leaved forests and hard-leaved mixed forests had obvious advantages and distribution areas,but they also invaded other landscape types.Growing environment;low-lying areas were disturbed by humans,the landscape distribution area was relatively small,the biodiversity was not high,and the high-lying areas were affected by the natural environment and the landscape distribution area was relatively low.
