A comprehensive and systematic study on flora composing，ecological distribution,
ecotype，ecological adaptation and economic value ofmacrofungi is carried out in the alpine
meadow of Jinqianghe，Tianzhu，Gansu during June to Oct．，2003．The results are obtained
as follows：
1．There are abundant macrofungi in Jinqianghe region are relatively rich．52 species，
which belong to 32 genera，and 1 8 families，had been identified from 74 specimens，
including 1 3 new records species for Gansu province，most of them are saprophagous
Basidiomycetes．The dominant families are Tricholomataceae，Coprinaceae and Agaricaeae，
whilethe dominant genera areCoprinus(11．5％)andAgaricus(9．6％)，inwhichthereare 21
single·，species genera and 9 single-species family．
2．The relativity with distribution of macrofungi and the terrain in Jinqianghe is
prominent．There are three types of ecological—distribution including Hemantan，Jiedi，
Yagaoshan-podi．The species，quantity and predominant species of these macrofungi vary
with different altitudes．That is，the fungi species increase from the layer Hemantan，Jiedi，
but decrease from layer Yagaoshan．The species and amount of the macrofungi are
predominant in the layer Jiedi．in which the dominant families are Tricholomataceae，
Agaricaeae．
3．Habitat heterogeneity is richer,there are 5 habitat types：Liggnicolous(1 1．5％)，
Geophilous(59．6％)，Coprophitous(13．5％)，Enrtomophilous(1．9％)，Mycorrhizal(15．4％)，
Geophilous and Coprophilous play a majoe role in them．
4.The macrofungi species in Jinqianghe have a better adaptation to the local climate
environment．The sporocarps of the macrofungi trend towards miniaturization，their main
colors are light and fairy ring occur frequently；from June to October occur many fungi，on
August the species and acount 8rre the most of which the dominant families are
Tricholomataceae，Coprinaceae and Agaricaeae，this has a close relation to temperature and
precipitation of last month，and appear“lap phenomenon”．The natural disturbance and
human disturbance all affect the ecological environment of Jinqianghe；the former are wind
erosion．drought，desert and landslip plot；the later are tourism，collection of the fire．wood，
over collecting，raising live-stock，fire．
5. The macrofungi have a beaer exploitation and utilization value，including 29 species
are edible，most of them are distribmed in Jiedi；20 species，pharmaceutical．10 of them
have anti—cancer activity；and 7 species，mycorrhizal；7 species，poisonous，there are two
toxic type，gastroenteritic and neuropsychic，ofwhich lnocybe rimosa、上Flavobrunnea are
deadly．
