摘 要
森林病虫害是威胁森林生态系统健康和稳定性的主要因素之一，其空间分布特征的研究对精准防控具有重要意义。本研究以某典型森林区域为研究对象，基于地理信息系统（GIS）技术，结合遥感数据与实地调查数据，分析了主要森林病虫害的空间分布规律及其影响因素。通过构建空间自相关模型和地理加权回归模型，揭示了病虫害分布的聚集性特征及其与环境因子之间的定量关系。结果表明，森林病虫害的空间分布呈现出显著的空间异质性，且受地形、气候及植被类型等多重因素的综合影响。本研究创新性地将GIS技术与统计分析方法相结合，实现了对病虫害空间分布特征的精细化解析，为制定区域化的病虫害防控策略提供了科学依据。研究的主要贡献在于提升了对森林病虫害空间动态机制的理解，并为生态管理实践提供了技术支持。关键词：森林病虫害; 空间分布; GIS技术; 地理加权回归; 环境因子
Abstract
Forest pests and diseases are one of the primary factors threatening the health and stability of forest ecosystems, and the study of their spatial distribution characteristics is of great significance for precise prevention and control. This study takes a typical forest area as the research ob ject and, based on Geographic Information System (GIS) technology, integrates remote sensing data with field survey data to analyze the spatial distribution patterns of major forest pests and diseases and their influencing factors. By constructing spatial autocorrelation models and geographically weighted regression models, the clustering characteristics of pest and disease distributions and their quantitative relationships with environmental factors are revealed. The results indicate that the spatial distribution of forest pests and diseases exhibits significant spatial heterogeneity and is comprehensively influenced by multiple factors such as topography, climate, and vegetation type. Innovatively combining GIS technology with statistical analysis methods, this study achieves a refined interpretation of the spatial distribution characteristics of forest pests and diseases, providing a scientific basis for developing regionalized pest and disease management strategies. The main contribution of this study lies in enhancing the understanding of the spatial dynamic mechanisms of forest pests and diseases and offering technical support for ecological management practices.Key words:Forest Pest And Disease; Spatial Distribution; Gis Technology; Geographically Weighted Regression; Environmental Factors
