摘要
以宽阔水国家级自然保护区为研究区域,选取了雉类、鹿类、猫科、灵长类等珍稀濒危动物以及保护区的主要对象亮叶水青冈林5类生态源,使用海拔、坡度、景观类型、基岩裸露等4个阻力因子解译阻力面分布格局,结合生态源点进行统计与叠加,识别出复合战略点。研究结果表明:针对5类生态源建立的综合阻力模型可以很好地模拟生物潜在分布;用传统的保护区功能区划法划分的功能保护区可很好地保护生态源地和鞍部战略点,但对交汇处战略点、复合交汇战略点、复合廊道的保护效果相对较差。结合研究结果,从功能区调整、空间化生态廊道建设措施以及时间上的管护措施提出了建议。
We took Kuankuoshui National Nature Reserve as research area,selected 4 types of endangered animals（ pheasant,cervid,felid,primate） and the main protecting species of the reserve（ Fagus lucida） as research objects,used 4 resistance factors（ altitude,slope,landscape,exposed bedrock） to interpret the distribution pattern of the resistance surfaces,and indentified the complex strategic points by counting and superposing the ecological source points.The results showed that,the resistance surface model could effectively simulate the potential biodistribution.The classical function zoning could well protect the ecological source and strategic points at saddle points,but failed to protect strategic points at intersections,complex strategic points at intersections and complex ecological corridors.Based on the research results,we put forward some advices from the aspects of function zone adjustment,ecological corridor construction and management measures through time.
