摘要
研究了海南岛橡胶林内人类的经济活动对海南山蛭Haemadipsahainana种群数量的影响。结果表明 ,橡胶园内牛群放牧使海南山蛭种群数量 1年内增加 3 43倍。化学除环山行杂草、化学全面积除杂草使山蛭种群数量在 1年内分别减少 2 9 82 %和 5 0 2 1%。除草剂混入杀蛭农药 ,使山蛭种群数量 1年内减少 73 0 2 %。科学的林段管理与控制山蛭数量相结合的措施 ,能更好控制山蛭数量。
The impact of human economic activity on the population dynamics of land leech in rubber plantations in Hainan was studied.The results show that cattle grazing in rubber plantations increased the population number of land leech by 3.43-folds within one year, while chemical weedings in rubber ledge contour and total area in rubber plantations reduced the population number by 29.82% and 50\^21%, respectively. Incorporation of leech-specific insecticides with weedicides could reduce the land leech population number by 73.02%. Scientific rubber plantation management in combination with chemical control was quite effective in the manipulation of land leech population in rubber plantations.
