| 摘 要： | 在洞庭湖区滩地对不同类型杨树抑螺防病林采取定位观测的研究方法,对滩地钉螺种群变化与抑螺防病林营造措施、林龄的关系及其内在机制进行了研究。结果表明:林分郁闭前,通过林农复合等林地土壤管理措施,改造钉螺孳生环境,可有效降低活螺和感染螺密度;林分郁闭后,林地水分、光照、植被等环境因子朝着不利于钉螺孳生的方向演变;滩地抑螺防病林生态系统抑螺效果具有显著性和持续性。

| Abstract: | Long-term observation was employed as the main research method to the study the relation of the dynamics of snail population to silvicultural measures and ages of different types of lakeside poplar plantations. Results indicated that prior to canopy closure forest land management measure such as agro-forestry to improve the habitat of snails could effectively reduce the density of living and infected snails. After canopy closure, the environmental conditions such as moisture, sunlight and vegetation evolved towards being unsuitable for reproduction of snails. The effects snail control of the lakeside plantation ecosystem was significant and continuous. |
