Effects of gap size on regeneration of Karst forest in Maolan Natural Reserve of Guizhou province;

Species diversity change pattern in gap gradient in karst forest in Maolan Nature Reserve, Guizhou Province;

Study on the regeneration niche of major tree species in gaps in the Karst forest in Maolan Nature Reserve;

163 species under 83 genera and 32 families, collected from Maolan karst forest area in Guizhou province, are reported in this paper; the distributions and resources review of them are also approached; all these known species are listed with their collection cites.

This paper recorded the Musci of Maolan Karst Forest Area, 186 species (including subspecies and varieties) belong to 93 genera and 28 families are reported.

The 25 plots of degraded karst forests were chosen as the research objects and 25 plots were divided into 11 forest types by principal component analysis(PCA).

The changes of SMBC and qSMBC of different soil layer,different microhabitats and rhizosphere,non-rhizosphere were studied during the process of degraded karst forest restoration by using the methods of microbial incubation and the chloroform fumigation-direct extraction.

The community structure of Karst funnel forest in Maolan has been studied by sample inventory.

Number classification of degraded Karst forests in the central Guizhou;

Based on the principles of restoration ecology and similarity,all species of successional stages in the natural restoration process of degraded karst forests were divided into five groups of adaptation grade.
