摘要
该文根据景观生态学原理，使用地理信息系统和遥感等技术，通过比较和分析该乡合理林网和现有林网的景观指标值，评价和研究了北京市大兴县北藏乡农田防护林网在景观中的宏观布局．结果显示，该乡农田防护林网的宏观布局不太合理。
The reasonable and existent landscape indexes of the farmland shelterbelt networks in Beizang town,Daxing county,Beijing are compared and analysed to study and evaluate the spatial pattern of the shelterbelt networks on the basis of landscape ecology, combining the remote sensing and GIS with field investigation. The results show that the spatial landscape pattern of the farml and shelterbelt networks is not reasonable.It is necessary to make strenuous efforts to construct the farm land shelterbelt networks in Beizang town.
