摘要
从干扰半径和干扰密度两个方面分析高速公路、国道、省道、县道、乡村道5类道路对大熊猫栖息地的干扰作用。结果表明:①道路级别越高、路面越宽、车流人流量越大,对大熊猫栖息地的干扰半径越大。②相比较而言,高速公路建设一般都会经历严格的环评,尽可能地避开大熊猫栖息地,实际上对大熊猫栖息地的干扰并不明显;小部分国道横穿大熊猫栖息地,对大熊猫造成了一定程度的干扰,但干扰密度也不大;研究区域内的省道对大熊猫的干扰密度最大,应引起重视;大部分县道不在大熊猫核心栖息地内,对大熊猫的干扰范围和干扰密度均较小;乡村道对大熊猫的干扰密度不高,但分布最广,因此总体干扰作用最大,应着重治理。
This paper analyzed the interference effects of five types of roads,including expressways national roads,provincial roads,county roads and rural roads to the habitat of giant pandas from two aspects of interference radius and interference density.The results showed that:①The higher the road level,the wider the pavement.The larger the traffic flow,the longer the interference radius to the giant panda habitat.②Comparatively speaking,the construction of expressways required strict environmental assessment to avoid the giant panda habitat as much as possible.In fact,the interference of expressways to the giant panda habitat was not obvious.A small number of national highways cross the habitat of giant pandas,causing a certain degree of interference to giant pandas,but the interference density was not strong.The provincial roads in the study area had the strongest interference density to giant pandas,which should be paid attention to.Most county roads were not within the core of the giant panda habitat,and the interference radius and density to giant pandas were small.Although the interference density of rural roads to giant pandas was not strong,it was the most widely distributed.Therefore,the overall interference effect was the strongest,which should be treated.
