昆嵛山国家级自然保护区物种水平指标的分析与研究

Analysis and research of species level indicator in Kunyu Mountain national nature reserve

对昆嵛山国家级自然保护区进行物种水平指标的分析与研究,结果表明:在物种多样性方面,Ⅴ级的分布面积最大,占保护区总面积的21%;Ⅳ级的次之,为28%;Ⅲ级处于中间位置,为21%;Ⅱ级和Ⅰ级的分布面积较小,分别为13%和7%。在植被盖度方面,Ⅴ级的分布面积最大,占保护区总面积的69%;Ⅳ级次之,为17%;Ⅲ级、Ⅱ级和Ⅰ级的分布面积较小,分别为9%、4%和1%。在物种水平方面,Ⅳ级的分布面积最大,占保护区总面积的43%;Ⅴ级和Ⅲ级的分布面积相差不大,分别为26%和25%;Ⅱ级以下的分布面积较小,仅为6%。

Analysis and research results of species level indicator in Kunyu Mountain national nature reserve indicated that in the aspect of species diversity , distribution area of level Ⅴwas maximum, accounting for 21%of total reserve area;lev-elⅣtook the second place , which was 28%;level Ⅲwas in middle position , which was 21%;distribution area of levelⅡand level Ⅰwas lesser , which was 13%and 7%, respectively .In the aspect of vegetation coverage , distribution area of level Ⅴwas maximum , accounting for 69%of total reserve area;level Ⅳtook the second place , which was 17%;dis-tribution area of level Ⅲ, level Ⅱ and level Ⅰ was lesser, which was 9%,4% and 1%, respectively.In the aspect of species level , distribution area of level Ⅳwas maximum , accounting for 43%of total reserve area;there was no signifiant difference between level Ⅴand levelⅢ, which distribution area was 26%and 25%, respectively;distribution area below level Ⅱwas lesser, only was 6%.
