摘要:

频繁的国际贸易加速了外来物种的入侵。然而,外来物种在入侵后的地理分布以及决定其分布的因素尚缺乏相关数据。本研究分析了中国入侵物种的分布变动趋势及其驱动因素。此外,还对改革开放前、1979年至2001年和中国加入世界贸易组织以来13种主要入侵昆虫在中国的空间分布进行了动态分析,以探讨增加国际贸易对中国入侵物种地理分布的影响。结果表明,入侵物种的丰度由南向北、由东南沿海向内陆逐渐减少。广东省(442种)和云南省(404种)的入侵物种丰度最高。在调查的13种重点入侵昆虫中,3个时期分别出现3种、10种和13种,入侵省份分别为7个、28个和34个。另分析显示,外来害虫主要经新疆、环渤海地区和东南部入侵我国。在所有因子中,进口贸易值是中国入侵物种数量的有力预测因子。进口贸易值和温度是解释除了微生物外的入侵物种丰度异质性空间分布的关键因子。研究结果为进一步开展国际检疫工作和有效控制入侵物种提供了科学依据。


Abstract: Frequent international trade has accelerated alien species invasion.  However, data on the distribution of invasive species after their introduction and research on the factors that determine their geographical distribution are lacking.  This study analyzed the distributional trends of invasive species in China and the drivers for such trends, by identifying the effect of international trade from a dynamic analysis of 13 main invasive insect pests in three time periods – before China’s reform and opening up in 1978, from 1979 to 2001, and after China’s accession to the World Trade Organization in 2001.  The results showed that the abundance of invasive species gradually decreased from south to north and from southeast coast to inland.  Guangdong (442 species) and Yunnan (404 species) provinces have the highest abundance of invasive species.  Among the 13 key invasive insects investigated, 3, 10 and 13 occurred chronologically in the three periods, and invaded 7, 28 and 34 provinces, respectively.  Alien pests are found to invade China through Xinjiang, the Bohai Rim and the southeast.  Value of imports was a strong predictor of the number of invasive species in China, and followed by temperature heterogeneity, in explaining the richness pattern of invasive animal, plants and insects, but not that of microorganisms.  This study provides a scientific basis for furthering international quarantine and effective invasive species control.
