Chino. 根据景观生态学原理,使用地理信息系统和遥感等技术,比较和分析了克拉玛依农业综合开发区合理林网和现有林网的景观指标值,评价和研究了克拉玛依农业综合开发区农田防护林网在景观中的宏观布局.结果显示,开发区现有农田林网在景观上的结构布局处于不合理状态,林网中缺株断带现象严重,林带数量不足,林网的分布很不均匀,成型状况也较差.因此,需要大力加强农田防护林的建设.[著者文摘]

The reasonable and existent landscape indexes of the farmland shelterbelt networks in agricultural comprehensive developmental region of Karamay were 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 showed that the spatial landscape pattern of the farmland shelterbelt networks is not adequately reasonable in this agricultural comprehensive developmental region.That is,there are some gaps in the windbreak.What is more,the quantity of the windbreak evidently presented the deficient situation,besides,the network distribution is asymmetry and the status of molding also had a poor performance.Therefore it is necessary to make great efforts to construct the farmland shelterbelt networks in agricultural comprehensive developmental region of Karamay.[著者文摘]
