长安区秦岭北坡种子植物多样性研究

Diversity of Spermatophyte in the North Slope of Qinling Mountains Located within Changan District

通过对秦岭北坡的种子植物的物种多样性、生活型多样性和区系成分多样性等分析研究,发现秦岭北坡长安区沣峪林场种子植物种类繁多。原始古老成分以及中国特有植物种类居多,区系成分复杂,各类成分并存。表现出种子植物种多样性和地理分布型多样性等特征。林下植被的结构与物种多样性反映了森林生态系统的结构状况,合理的树种配置可促进林下植被的良好发育,有效提高人工林生态系统的稳定性,并可改善生态系统的服务功能和健康评价。

The biodiversity of spermatophyte, biotype and components of flora in the north slope of Qinling Mountains located within the Chang＇an district were studied. The result showed that spermatophyte in Chang＇an district is of great diversity. The plants of original components and the plants native to China in the flora are much, with complex composition of flora. The structure and diversity of the understory plants reflected the structure of forest ecosystem. Rational mixture of plants could improve the regeneration of plants, maintain the stability of ecosystem of plantations and improve the service functions and health of ecosystem.
