摘 要:为保护我国典型的大巴山南坡植被格局及生物多样性,保护世界极危物种——崖柏(T.sutchuenensis Franch)及其生境,保护相对纬度、海拔最低的大面积的亚高山草甸,保护石灰岩山地常绿阔叶林等多种植物群落类型,保护亚热带-暖温带过渡性生境和生物区系,保护珍稀濒危野生动物及其栖息地等,2002年重庆雪宝山被确定为重庆市市级自然保护区。以该保护区的多样性、代表性、珍稀性、自然性、面积适宜性、稳定性、人类干扰7项要素为主要内容。对重庆雪宝山进行AHP生态评价,研究结果说明雪宝山生态质量较好,保护的优先程度较高,具有重要的生态价值、经济价值和社会价值。In 2002, the Congqing Municipality government established Xuabaoshan (or the Xuebao mountains) as a municipal natural Conservation, so as to protect the traditional vegetation pattern and bio-diversity of the southern slope of the Daba Mountains, to protect T. sutchuenensis Franch, which is on severe danger, and its habitat, to protect the extensive subalpine meadow, which is located at lowest latitude and altitude, to protect various plant community types such as evergreen broad-leaved forest in limestone mountain region, transition habitat in sutropics-warm-temperate region and bioflora, and to p.rotect precious wildlife, which is on the verge of extinction, and their habitats. In this paper, based on seven factors in the Conservation , ~ncluding diversity, representativeness, spatial natural suitable areas, stability, and human - impact, ecological assessment was made of Xuebaoshan by means of the AHT method. The results show that its ecological quality is relatively good, its conserved priority is satisfactory, and it has significant ecological, economic and social values.
