GIS技术在农田防护林优化配置中的应用

The Application of Optimization Arrangement of Shelterbelts Using GIS Technology

在对建湖县林带生长模型拟合与优化结构指标理论分析的基础上,提出了针对研究区农田防护林的三级配置方案,并应用GIS空间分析和统计功能,完成了研究区的林带、林网的空间配置。结果表明:在优化配置的条件约束下,森林覆盖率有明显的提高。利用GIS技术对农田防护林空间配置的研究,可为农田防护林的管理和经营提供更为直观、科学的依据,为管理者提供新的管理手段和方法。

Based on the optimal structure analysis and optimal growing model curve estimation of the Jianhu shelterbelts, three scale scheme aiming at the study area was brought out. Applying the spatial analysis and statistics function of GIS, the spatial arrangement of shelterbelts of study area was accomplished. The result shows that the forest cover percent of study area was improved distinctly under the condition of optimization arrangement. The application of optimization arrangement of shelterbelts using GIS technology provides the straight and scientific foundation in shelterbelts management.
