作为风景的一个内在的骚乱因素，道路是明显的人工的部件。地区性的风景模式和变化被道路网络的存在和延期影响。在道路特征和它的骚乱水平之间的关系的学习为地区性的生态系统管理是重要的。在 LRGR 基于道路走廊和网络特征的空间变化分析，我们用 GIS 在风景模式变化上检验了道路网络的效果。进一步，在地区性的生态的骚乱之间的整齐和网络特征被讨论。道路密度是的结果 showe 显著地，相对地形学，村庄数字和生态系统，补丁数字，和意义与道路类型极大地变化了。随道路密度和网络扩展的增加，(网络电路) ，，并且((边节点比率) ，并且(联网连接) 索引增加了。另外，总计当地区性的最小的补丁区域，平均补丁区域和传染索引减少了时，增加的生态系统补丁数字，补丁密度，风景平均和分数维的索引。低档道路有的结果展览地区性的风景破碎上的更大的效果。我们使用了 1980 和 2000 的人的骚乱索引(H d ) 显示生态的骚乱水平。H d 索引与的一种积极、重要的关系，和索引，它建议生态的骚乱与网络增加了膨胀。

英文摘要：

As an intrinsic disturbance factor of landscape, roads are conspicuous artificial components. Regional landscape pattern and change are influenced by the existence and extension of road networks. Study of the relationship between road features and its disturbance level is important for regional ecosystem management. Based on the spatial variation analysis of road corridor and network features in the LRGR, we examined the effect of road network on landscape pattern change using GIS. Further, the regularity between regional ecological disturbance and network features was discussed. The results showe that road density was significantly relative to topography, village number and the ecosystem patch number, and the significance varied greatly with road types. With the increase of road density and network ex- tension, α （network circuitry）,β （edge-nodes ratio） and γ（network connectivity） indexes increased. Also, total ecosystem patch number, patch density, landscape evenness and fractal index increased while regional minimum patch area, average patch area and contagion index decreased. The result exhibit that low-grade road had greater effect on regional landscape fragmentation. We used human disturbance indexes （Hd） of 1980 and 2000 to indicate the ecological disturbance level. The Hd indexes have a positive and significant relationship with α,βand γindexes, which suggests the ecological disturbance increased with the network expanding.
