广东孔江国家湿地公园植物多样性

Diversity of Plant of Kongjiang National Wetland Park of Guangdong Province

2014年12月和2015年4月,采用路线调查与标准地调查相结合的方法,结合历史资料,对孔江国家湿地公园的野生植物资源进行了实地野外调查,分析了植物区系和植物多样性及其受威胁状况。结果表明,该保护区具有丰富的植物物种多样性,有维管植物种类142科392属588种,其中国家重点保护野生植物有8种;该区植物区系成分具有复杂性和多样性,拥有中国种子植物分布区类型属级水平的大部分类型,区系表现为热带亚热带性质;该区具有丰富的植被类型,包括5个植被型、6个植被亚型和9个植被类型,具有较高的保护和科研价值。同时针对保护区植物多样性受威胁状况,提出了水质保育、水岸恢复、科研检测体系建设、可持续利用等保护植物多样性的有效措施。

We investigated wild plant resources of Kongjiang National Wetland Park of Guangdong Province by using the combined method of route survey and standard survey in December, 2014 and April, 2015, and then analyzed flora, plant diversity and their threatened status. Results showed that： the conservation area was rich in plant species diversity, and had vascular plants 142 families, 392 genus, 588 species, among them 8 species belonged to the national key protected wild plants;floristic elements of the conservation area had complexity and dlversi- ty, had most types of Chinese seed plant distribution type at genus level, and showed tropical subtropical properties ; the conservation area was rich in vegetation types, included five vegetation types, six vegetation subtypes and nine vegetation types, and had high value of protection and scientific research. Finally, aimed at the threatened status of plant diversity, some effective measures were put forward, such as water conservation, water bank recovery, research and testing system construction, sustainable utilization, and so on.
