摘要：目的探讨云南省高原山区核桃抑螺防病林下草本植物变化与钉螺分布关系。方法采用空间替代时间法选择云南省洱源县兴林抑螺综合试验示范区的不同林龄(2、4、6、8、10年)核桃林为试验组,并以无林地作为对照组。观察两组林分生长情况及林下草本植物的种类、生物量、盖度、高度,土壤湿度,核桃生长情况及螺情变化。结果6年生核桃抑螺防病林基本郁闭(0.65);在郁闭度为0.77的核桃林(10年生)中林下有6科11属11种草本物,科、属、种数分别较对照组下降了64.71%、69.44%和77.08%,林下草本植物生物量、盖度、高度分别是对照组的12.63%、19.00%和22.18%。林地土壤平均含水率月变幅随林龄增加而明显增大,除对照组和2年生核桃林中发现钉螺外,其他各组均未查获钉螺,且2年生核桃林中的活螺框出现率为1.25%,较对照组下降了50.00%,活螺密度较对照组下降了60.16%。结论云南省高原山区(核桃适生区)营建核桃抑螺防病林可抑制草植物生长,改变钉螺孳生环境。如适当进行林下间作,在兴林抑螺的同时可达到建设美好生态环境,提高土地、光、热等资源利用率及农民经济收入的效果。
Objective To explore the relationship between the changes of herbaceous plants and Oncomelania hupensis snail distribution under the walnut forest of inhibition of snails in mountainous regions of Yunnan Province. Methods The experimental field was established at Sanying Village of Eryuan County,Yunnan Province,where the＂Flourishing Forest and Controlling Snails Project＂was implemented. The different stand ages（2,4,6,8,10 years）of walnut forest in experimental groups were selected based on the method of space replacing time,and the non-stocked land was served as a control group. The growth of forest, change of snails,number,biomass,overcast,height of the herbaceous plant and the soil moisture were investigated. Results The crown closure of 6-year-old walnut forest of inhibition of snails was 0.65. There were 11 species of herbaceous plant belonging to 11 genera,6 families in 10-year-old forest and its crown closure was 0.77. Compared with the control group,the numbers of families,genera,and species of the 10-year-old forest were decreased by 64.71%,69.44%,and 77.08%,and the biomass,overcast, and height of it decreased by 12.63%,19%,and 22.18%,respectively. The soil moisture content（0-20 cm）monthly changes were increased obviously with the increase of stand age. There were no snails besides the control group and 2-year-old walnut forest. Compare with the control group,the occurrence rate of frames with living snails in the 2-year-old walnut forest was decreased by 50%,which was 1.25%. The density of living snails was decreased by 60.16%. Conclusions The construction of walnut forest of inhibition of snails in mountainous regions of Yunnan Province are suitable for controlling the growth of herbaceous plants and altering the environment of snails. If the coalescence intercropped with crops is carried out,it is not only beneficial to the construction of good ecological environment,but also improves the utilization efficiencies of land,light,and thermal resource,and the income of peasants.
