浙江石垟森林公园种子植物区系特征的统计分析

在野外调查、标本鉴定和浙江文成石垟森林公园种子植物名录编写的基础上，对该地区的种子植物区系特征进行了统计分析。结果表明：该地区植物种类丰富，计有野生种子植物132科440属726种（包括种下分类群），发现温州地理分布新记录43种；该区系地理成分复杂，分为14个类型，和全国比较，仅缺中亚分布类型；热带和温带分布的属分别占44.2%和53.4%，具较明显的南北过渡现象，由于文成石垟森林公园所辖范围多在海拔400 m以上，因而具有较高比例的温带成分。区系成分中包含了中国特有成分9属，国家重点保护野生植物10种及众多的濒危珍稀植物。文成石垟森林公园的植物在生物多样性保护中具有较重要的地位。表3参17

Floristic analyses of seed plants in Shiyang Forest Park,Zhejiang Province

To provide basic data for biodiversity protection 400 m, in Wencheng County, specimens were identified, of Shiyang Forest Park, which is mainly above a seed plant list was compiled, and seed plant floral characteristics were analyzed. Results showed that seed plants included 132 families, 440 genera, and 726 species with 43 newly record species for the Wenzhou geographical distribution area. The 440 genera were divided into 14 areal types except Central Asia in this area compared to .China. For these genera 44.2% were tropical and 53.4% temperate with nine Chinese endemic genera and 10 species belonging to Chinese key wild protected plants and rare or endangered species. Thus, transitional floristic elements from temperate and tropical climes characterized the flora, but due to its elevation, temperate types dominated. These seed plants could be important for biodiversity protection in Shiyang Forest Park. [ Ch, 3 tab. 17 ref. ]
