Studies On The Macrofungi Diversity In Zhanhe Forest Farm Of Heilongjiang Province

This paper studies the macrofungi from four aspects which are speceis diversity, flora diversity, the correlation of vegetation type and the Macrofungal diversity in the different recovery phase for the deforestation in Zhanhe Forestry station in Heilongjiang province. Species diversity:About600species were collected which belong to169genera,38families,73genera, including10new record species to Heilongjiang province. The list was compiled according to the Dictionary of the Fungi (the tenth edition).Flora diversity:The Flora diversity was abundant in Zhanhe Forestry station in Heilongjiang province. There were4families which had more than ten species and75species in all that accounted for44.4%in all species and10.5%in all families respectively. There were8genera which had more than5species and71species in all that accounted for42%in all species and11%in all genera respectively.Correlation between macrofugal diversity and flora types:After studying the macrofungal diversity in different floras, the flora types were divided into4different types in the forestry station:shrubwood (Ⅰ), grassland (Ⅱ), broar-leafed forest (Ⅲ), theropencedrymion (Ⅳ), coniferous forest (Ⅴ).Analysing the macrofungal diversity in different vegetation types, the ratio of the forms descending order were like this:typeⅤ>typeⅢ>typeIV>type Ⅰ>type Ⅱ.The different recovery phase for the deforestation to macrofungi diversity:It concluded that the effects for the macrofungi by selective felling way of different felling time in Zhanhe Forestry station. Deforestation in different times showed that the way of deforestation had effects on the Macrofungi. The different recovery situations had little influence on the composition of Macrofungi. However, the diversities were affected slightly.
