野兔对人工幼林危害的研究

随着退耕还林还草,天然林保护等工程在太谷范村地区实施,当地生态环境得到有效改善,但随之而来的野兔泛滥和对当地人工幼林的危害,带来的经济损失是巨大的。作者通过对山西太谷范村林场的野兔危害进行了实地调查,用统计等方法分析了危害的原因及程度,为森林资源的动态分析提供了可靠的数据。

As the afforestation, the protections of natural forest are carried out in Fan Cun of Tai Gu County. The local eco- logical environment has been improved obviously. But the following overflow of hares gradually becomes the natural harm of living things, especially the harm that hares do to the artificially young growth,and the economic lost that causes is greatly seri ous. So we need to research the Fan Cun tree farm of Tai Gu on the spot,it is can suggest the ensure date of forest＇s dynamic analyses by with mathematical statistics analyses the reason for the harm that hares do to the artificially young growth.
