ArcGIS技术在冀北山地落叶松种群结构调整中的应用

Application of ArcGIS Technology to Adjust the Population Structure of Larixgmeliniiin Northern Hebei Province

为使林业生产者运用现代化手段进行营林生产规划和决策,从而提高林业工作的高效性,以河北省木兰林管局北沟林场为例,依托ArcGIS技术,由二类调查数据提取落叶松林数据源,结合实地踏查情况,对其进行统计分析。结果表明:通过3个林分类型即落叶松乔林、其它针叶乔林、杨桦落叶松中林生成的斑块图确定4种经营类型为防护林、均质经营林、苗材兼用林、目标树经营林,提出对落叶松林种群结构调整的抚育措施;从斑块着色处理、版面设置到图例的生成,最终形成合理营林生产规划设计图。说明ArcGIS技术可在现代林业中发挥作用,为林业生产者提供方便快捷的技术平台,使林业工作也进入了电算化时代。

In order to make the forestry producers use the modern means to carry out the planning and decision- making for forest production,and to improve the efficiency of the forestry work, taking the Beigou Forest Farm of Mulan Forestry Bureau in Hebei province as an example, relying on ArcGIS technology, the data sources of larch forest were extracted from the second survey data,combined with field inspection situation,its statistical analysis. The results showed that the four types of plants were used as shelter belts,homogeneous forest, nurs- ery stock and forest,and the target tree was established by using three plots of three forest types,namely,larch forest,other coniferous forest,the larch structure adjustment of the tending measures were put forward; from the patch coloring processing,layout set to the generation of the legend,the final formation of a reasonable for- est production planning and design. The specific application of ArcGIS technology in modern forestry was de- scribed to provide convenient and quick technical platform for forestry producers to make forestry work and en- ter the era of computerization.
