| 中文摘要: |
| 中甸叶须鱼(Ptychobarbus chungtienensis chungtienensis)是云南碧塔海唯一的土著鱼类,也是当地重点保护鱼类,近年来其种群数量有下降的趋势。2007年7月至2011年6月对碧塔海的水生生物进行了连续监测,在掌握了中甸叶须鱼生态学数据的基础上,利用漩涡模型(Vortex 9.99)分析了其种群生存力,预测了理想状态下未来100年内中甸叶须鱼的种群动态以及由于自然灾害和人为干扰等外界因素的变化导致其种群的变动趋势。结果显示,在一定几率自然灾害发生的前提下,随着人为干扰程度的加深,中甸叶须鱼面临灭绝的风险也将增大。为维持碧塔海的水生生态平衡,保护区应当加强管理,合理开发,尽量减少人为干扰,加强水生生物的监测力度,对叶须鱼的保护应引起足够的重视。 |
| 英文摘要: |
| Ptychobarbus chungtienensis chungtienensis is the only endemic fish species of Bitahai Lake，Yunnan，China. It is also a kind of endangered species and there is a down trend in its population size in recent years. From July 2007 to June 2011，a continuous monitor of the aquatic life in Bitahai Lake was conducted. With the first hand ecological data，we did the population viability analyses using Vortex 9. 99，and the population dynamics of P. chungtienensis chungtienensis under ideal conditions or two kinds of catastrophes(i.e. natural disasters and human interference)were predicted in the following 100 years. Results of the simulation suggested that，under the premise of a certain probability of natural disasters，the deeper the degree of human interference was，the higher the probability that P. chungtienensis chungtienensis went extinct. To keep the ecological balance of the Bitahai Lake，the protected areas should reinforce the management，do rational development，minimize human interference，strengthen the monitoring of the aquatic organisms，and bring the protection of P. chungtienensis chungtienensis to the forefront. |
