宣州区森林、草地、湿地生态系统外来入侵物种调查及分析

Survey and Analysis on the Invasive Alien Species in the Forest,Grassland and Wetland Ecosystems in Xuanzhou District

宣州区属于亚热带季风湿润气候区,复杂而优越的自然环境孕育了种类繁多的本土动植物物种,也为外来入侵物种的生长和繁衍创造了有利条件。本文通过对宣州区森林、草地、湿地生态系统内的外来入侵物种进行调查,结果表明:宣州区存在外来入侵植物23种,隶属10科18属,主要以草本植物为主;入侵动物4种,分别是红耳龟、福寿螺、美洲牛蛙和悬铃木方翅网蝽。这些外来入侵物种对当地农林牧渔业可持续性发展和生物多样性可能造成潜在损害。本次调查结果有望为全省外来物种防治工作提供参考。
