穿越辽宁滨海公路的动物物种调查及保护对策

选取辽宁滨海公路8个典型段落代表4种生境类型,对穿越公路的动物物种进行了8次调查。结果显示:共发现动物23种(包括亚种),隶属14科(包括亚科)、18属;湿地和水田段落穿越动物物种的相似性指数最大(0.615);水田与旱田动物物种的相似性最小(0.167);不同生境的路段穿越动物的种类与频次差异较大,湿地与水田段落的穿越动物种类少而数量多;草地与旱田段落的穿越动物种类多而数量少。为此,提出在动物通道设计中,要根据动物类别确定通道形式,根据生境类型确定目标物种。

Investigation on Road Crossing Animal Species of Coastal Highway in Liaoning and Its Protection Countermeasures

The investigation on road crossing animal species had been conducted eight times, as eight typical paragraph of Liaoning Coastal Highway had been selected to represent on behalf of four habitat types. The results showed that 23 species (including subspecies) were found, which belong to 18 genera and 14 families (including subfamily); the similarity index of crossing animal species between wetlands and paddy field paragraph is the largest (0.615); the lowest (0.167) is between paddy field and dry field paragraph; road crossing animal species and their frequency are bigger in different habitats paragraph, they are less in species and more in quantity from wetlands and paddy field paragraph, while more in species and less in quantity form grassland and dry field. Therefore, this paper had provided that we should determine animal passage forms according to the animal category and determine target species depending on the type of habitat in the design of animal passage.
