摘要
2014年3月至2015年3月,采用样线调查方法对洋县境内中华鲎虫和丰年虫进行调查。结果表明:中华鲎虫在洋县有小种群分布,随海拔升高,数量越来越少。丰年虫数量极少,只在2处发现5只成体,亟须加强保护研究。
From March 2014 to March 2015,line transect method was used to investigate the distribution of Triops sinensis and Chirocephalus diaphanous in Yangxian County. Results showed that small population of Triops sinensis distribute in Yangxian County. Along with the increasing of altitude,the number was getting smaller and smaller. The number of Chirocephalus diaphanous was rare even in the bumper harvest year,only five adults were found in two places,and it was urgent need to strengthen the protection and research.
