摘 要:应用资料收集法和实地调查法,调查、评估并分析了东北林蛙养殖区域自然生态变化趋势、东北林蛙养殖业从业人员行为的影响及养殖业发展的可持续性。结果表明开展林蛙半人工养殖的区域几乎全部是自然生态状况良好、具有重要保护价值的区域;林蛙半人工养殖方式极大地提高了区域性森林生态系统中林蛙的数量,进而将导致自然生态系统发生一系列变化,这些变化对自然生态状况的影响有利有弊,并存在不确定性;林蛙养殖从业人员的从业行为或行为倾向,既有有利于当地自然生态保护的一面,也有不利于当地自然生态保护的隐患。在调查与分析的基础上,提出了如下建议:加强林蛙资源本底调查,坚持对林蛙半人工养殖区域自然生态变化的监测和研究,统一林蛙半人工养殖区域各经营活动的经营权,研究制定东北林蛙半人工养殖技术规范,引导从业人员规范操作等。The changing trend on natural ecology in breeding areas of northeast forest frog,the effect of practitioner’s behavior and the sustainability of frog breeding were investigated,evaluated and analyzed.The research indicated that the artificial breeding were always in the areas with better nature resources and important values for protection.Semi-artificial breeding remarkably improved the quantity of the northeast forest frog population in local forest ecosystem,and induced a set of changes of the nature ecosystem.But these changes were uncertain.The behaviors and prefers of employees not only benefit to local nature conservation,but also maybe damage the nature.Based on the research,investigation of northeast forest frog,monitoring and studying the changes of nature in semi-artificial breeding areas should be strengthened.And unifing the right of operating activities,establishing technique criterion,leading practitioners to operate with standardization are proposed.
