矮牡丹濒危机制分析与保护对策

矮牡丹是中国特有的珍贵种质资源,全国现仅存有六个居群,主要分布于陕西,山西和河南交界的部分山区,居群内数量很少。其种群类型,形态特征,生长习性及濒危状况尚未详细研究报道。调查结果表明矮牡丹现有的生存环境已遭到破坏,生长发育缓慢,自然繁殖能力差。研究分析了矮牡丹在自然界的濒危机制,提出了建立矮牡丹自然保护区,促进自然种群的繁衍,设立人工繁育苗圃等保护措施。这对于保存中国濒危物种资源具有非常重要参考价值,对珍稀濒危植物的保护和合理开发利用具有实际意义。

Endangered Mechanism and Conservative Strategies of Dwarf Peony

Dwarf peony (Paeonia suffruticosa Andr. Var. spontanea Rehd) is an endangered species in China. The population naturally distributes in the adjacent areas between Shaanxi, Shanxi and Henan provinces. There is limited number in the population and the population type, morphological characteristics, growth habits and endangered situation has not been well documented. This paper analyzes its endangering mechanism in the light of natural environmental factors and artificial influences, proposes effective approaches of conservation, including establishment of natural reserve and propagation site. This study provides a important example for protecting endangered species in China and effective utilization of these valuable and endangered plant species
