大鸿寨山野生黄栌生态学特性及的应用

大鸿寨山野生黄栌生态学特性及的应用   摘要:为查清河南省禹州市大鸿寨山野生黄栌种群的生态学特征,解决其种质资源的有效保护和可持续利用问题,采用植物群落野外调查方法和地理信息系统技术研究了大鸿寨山野生黄栌的种群类型、生态特性。结果表明,大鸿寨山野生黄栌有3个变种;有5种植被型,其中1种为纯林,4种为混生灌丛,经种群数量特征量化分析,属于大鸿寨山山地旱生生境的优势生态类群大多分布于山顶、缓坡上,具有耐土壤干旱、耐寒、种子萌发力强等特点,既可以做山地次生林改造时的保留树种,又可以当园林绿化观赏、药用、化工原料等资源型植物,具有较大的综合开发应用价值,应加快其野生引种技术的研究,兼顾保护与合理利用。   关键词:黄栌;种群;生态学特性;应用;大鸿寨山   中图分类号:Q949.754.4;Q948.15;X173(614YZ) 文献标识码:A 文章编号:0439-8114(2012)14-3031-05   Ecological Characteristics of Cotinus coggygria Resources in Dahongzhai Mountain and Its Application   DONG Dong-ping,JIANG Gang-cheng   (School of City and Environment, Xuchang University, Xuchang 461000, Henan, China)   Abstract: In order to find out the ecology characteristic of wild Cotinus coggygria Scop. population in Dahongzhai Mountain in Yuzhou city Henan province, provide references for effective protection and sustainable utilization of the germplasm resources, field survey method and geographic information system technology was adopted to study the population types and ecological characteristics. The results showed that there were 3 variations of wild C. coggygria in Dahongzhai Mountain; and 5 vegetation types, including 1 pure forest, 4 mixed shrub were find out. According to population quantitative analysis, the quantitative characteristics of C. coggygria population belonging to the dominate population in mountainous drought environment in Dahongzhai Mountain mostly distributing in top hill and gentle slope. The population was resistant to drought and cold, and with strong seed germination activity, thus could be the retention species for secondary forest, as well as resources plant for ornamental, medicinal, chemical raw materials, which was with great development value. The wild technology research, balanced protection and reasonable use of this plant should be pay attention to.   Key words: Cotinus coggygria Scop.; species; ecological characteristics; application; Dahongzhai Mountain   黄栌(Cotinus coggygria Scop.)属于漆树科(Anacardiaceae)黄栌属[Cotinus(Tou
