摘要
根据山西省太原市林场红脂大小蠹的发生、发展、扩散等动态过程,探讨了G IS在红脂大小蠹综合治理中的应用。从红脂大小蠹的发生地入手,对实地进行了详细的调查研究,将野外调查资料建立了详细的数据库,初步完成了红脂大小蠹信息的数字化。建立了太原市林场电子地图,叠加了森林资源信息和红脂大小蠹分布、危害信息,对红脂大小蠹发生的区域进行了准确的定量描述,并在此基础上,利用T itanG IS软件对红脂大小蠹发生、发展规律以及与环境因子的关系进行了分析研究,为准确地确定防治面积,设计合理的防治决策,提供了依据。
According to the dynamic process of occurrence, development, and dispersion of Dendroctonus valens, the application of GIS on controlling Dendroctons valens was studied. The digital information of Dendroctonus valens was finished by building the data of the field investigation material on the spot. The occurrence area of Dendroctonus valens was described exactly by electronic map of forest farm, the forest resources information, and insect distribution and harmfulness. The paper analyzes the relationship between the occurrence, development law of Dendroctons valens and environment factors by TitanGIS. All this will provide assistance for defining control area, designing reasonable control measure to Dendroctons valens.
