中文摘要：

降低林地景观的破碎化程度,对生物多样性保护、森林经营及林地生态功能发挥均具有重要意义。该文利用GIS技术提取典型县域非农用地与林业用地的面积及斑块资料,在乡村尺度上研究非农景观对林地破碎化的影响。结果表明,不同林地的破碎化程度存在显著差异,有林地最大,其他林地次之,灌木林地最小;村域非农景观广泛镶嵌于林地景观中,其面积和斑块数量存在较大差异;非农景观对有林地的破碎化存在显著正相影响,对灌木林地和其他林地的破碎化影响为负且不显著。文章认为,深化实施新农村建设和集体林权制度改革,能够有效减少非农景观面积并优化其空间布局,是降低乡村林地破碎化的重要举措。

英文摘要：

Lowering the degree of fragmentation about forest landscape is significant for biodiversity conservation,forest management and forest ecosystem functioning.The area and plaque of non-agricultural land and forest land in typical county were extracted by GIS,and effects of non-agricultural landscape on forest fragmentation were discussed.The results show that there was a remarkable discrepancy in the different forest fragmentation.The order as followings： woodlandother forest landshrub land;Most of non-agricultural landscapes in the village are mounted in the forest landscape.There area and plaques were obvious different.Non-agricultural landscape had a positive on the woodland fragmentation,but had a negative and subtle effect on other forest land and shrub land fragmentation.According to the findings,deeply implementing the new rural construction and the reforming the collective forest right system can effectively reduce the area of non-agricultural landscape and optimize its spatial distribution,are the important measure to lower the fragmentation of rural forest land.
