滩地林分郁闭度与钉螺密度关系的研究

Study on Relations with Stand Crown Cover and Oncomelania Hupensis Density on Beach Land

林分郁闭度大小是改变林下生态环境的主导因素,通过对林下草本植物分布变化以及林下温度、湿度、光照及地下水位等因子的调查分析研究,结果表明:滩地林分郁闭度大小与钉螺密度呈负相关关系。

Size of stand crown cover plays a main role in changing ecological environment under the forest. Studies and analysis focus on distribution of grass plants, temperature, humidity, illumination under the forests and underground water level etc. The result shows that the size of the stand crown cover performs negative correlation with the density of Oneomelania hupensis on the beach land.
