摘要
通过对长沙市绕城高速公路、长永高速公路、永浏高等级公路和岳麓山风景区周边高等级公路的考察,并以岳麓山风景区周边公路网作为研究模型,概述高速公路网络对自然区域野生动物的生存空间及活动通道的分割,而影响野生动物的觅食、迁徙和基因交流,导致生物物种衰退或消亡的趋势.
Based on the research of round the city highway in Changsha, Changsha Yongan highway, Yongan Liuyang high ranking road and surrounding highways of Yuelu Mountain Scenic spot, taking the road network around yuelu Mountain as a model. The separation of wild animals' living territory and activity passage by highway network as well as the influence on their living, migrating and gene exchange, thus causing the tendency of declining or extinction of biological species are analyzed.
