陕西马家山自然保护区大中型兽类的资源及区系与生态分布 总被引:1,自引:0,他引:1
马家山自然保护区(105°28′~105°40′E,32°50′~32°56′N)属秦岭西段的南坡山地。采用样线调查法和访问调查法,于2004年10~11月,对该保护区大中型兽类(包括灵长类、食肉动物和偶蹄动物)的资源、区系和生态分布进行了研究。该保护区共有23种大中型兽类,其中属我国Ⅰ级、Ⅱ级重点保护动物的兽类分别有5种和9种。它是秦岭物种多样性保护的关键地区之一。金丝猴和猕猴在此同域分布,大熊猫和羚牛四川亚种也分布于此地,该保护区是这4个珍稀濒危物种的一个新分布区。区内的23种兽类中没有古北界的区系成分,而属于东洋界成分的兽类有17种,占73.9%;其余6种为广布种,占26.1%。分析该区域23种兽类的生态分布发现,常绿落叶阔叶混交林、落叶阔叶林和针阔叶混交林中分别有16种、20种和12种动物活动。这些物种的垂直分布幅度有很大的差异。垂直分布幅度在海拔高差1000 m以上、500~1000 m、500 m以下的物种分别有5种、13种和5种。区内不同海拔带的兽类物种数随海拔升高的变化比较平稳,没有表现出明显上升或下降的规律性变化。 相似文献

牛背梁自然保护区食肉目和偶蹄目动物的区系特征与生态分布 总被引:4,自引:0,他引:4
牛背梁自然保护区(108°45′~109°04′E,33°47′~33°56′N)位于秦岭山脉东段,地跨秦岭南北坡。采用样线调查法和访问调查法,于2003年5月~2004年8月,对该保护区食肉动物及偶蹄动物的区系特征和生态分布进行了研究。该保护区共有18种食肉动物及偶蹄动物,其中属我国级、级重点保护动物的兽类分别有2种和7种。分析表明,保护区的有蹄类动物物种丰富,秦岭分布的有蹄类在该区域均有分布,但食肉动物种数仅占整个秦岭地区的45.5%。这些兽类中,属于东洋界的兽类有12种,占66.7%;属古北界的仅1种,占5.5%;其余5种为广布种,占27.8%。牛背梁保护区在动物地理区划上应属古北界和东洋界物种交汇的区域,且为东洋界逐渐向古北界过渡的区域。分析该区域食肉动物及偶蹄动物的生态分布发现,这些物种的垂直分布幅度有很大的差异。垂直分布幅度在海拔高差1300m以上、1000m左右、450~700m之间的物种各占1/3。结果还表明,区内这些兽类物种的丰富度随海拔的升高具有先升后降的垂直变化规律。不论是秦岭南坡还是北坡,分布在海拔1800~2200m区域的兽类物种最多,所占比例大于80%;而在海拔2600m以上区域,兽类种数降至最少,仅占50%左右。兽类丰富度的海拔梯度也体现于这些兽类在各植被类型中的分布上。中山针阔叶混交林中分布的兽类种数最多,而在中低山落叶阔叶林、亚高山针叶林及亚高山灌丛草甸中分布的兽类则较少。 相似文献

Niubeiliang National Nature Reserve (NNR, 108°45′–109°04′E, 33°47′–33°56′N) is located on the eastern range of the Qinling
Mountains in Shaanxi Province, China and spans the southern and northern slopes of Mt. Qinling. A transect survey and investigation
were carried out in NNR to determine the fauna characteristics and ecological distribution of carnivora and artiodactyla from
May 2003 to August 2004. The NNR has 18 mammals (carnivore and artiodactyl), two of which belong to the first class and seven
to the second class of state key protected wildlife in China. The results of this study indicated that ungulates were abundant
in the NNR, as all ungulates that were distributed within Mt. Qinling could be found within the reserve. However, only 45.5%
of the carnivores distributed within Mt. Qinling were detected within the NNR. Among the mammals, there were 12 oriental species
(66.7%), 1 palearctic specie (5.5%) and 5 widely-distributed species (27.8%). The NNR is a crossing area of palearctic species
and oriental species on the zoogeographical regions, and it is a transitional area from the oriental realm to the palearctic
realm. The results of the analysis on the ecological distribution of carnivore and artiodactyl in the area showed that their
elevation ranges had large differences. The species whose elevation ranges above 1 300 m, about 1 000 m, and in 450–700 m
occupied one third respectively. The results also indicated that species richness for the memals in the NNR peaked at a middle
elevation (rising at first, then descending with the increase in elevation). Not only on the southern slope, but also on the
northern slope of Mt. Qinling, the number of species distributed in the area at 1 800–2 200 m a.s.l. was the largest (more
than 80%), while the number of species distributed in the area above 2 600 m a.s.l. was the smallest (about 50%). Elevation
gradients of species richness for the mammals in the NNR also embodied the mammal distributions among the vegetation types.
The number of species distributed in the mixed coniferous and broadleaf deciduous forest at middle elevations was the largest,
while the number of species distributed in the broadleaf deciduous forest at middle and low elevations, subalpine coniferous
forest, subalpine shrubbery and meadow was relatively smaller.
