Plant divesity of Peatlands and related Organic Substances Humic and Fulvic acids

[Abstract] Peatlands are regarded as a complex habitat type, that contain a full range of development:from ombrotrophic to geotrophic mires; dystrophic to eutrophic, calcareous fens to acidic bogs and so on. They occupy a wide range of environmental conditions and dynamic systems which form part of the hydroseral succession from open water to dryland sustaining a rich variety of plant species. The principal abiotic factors which influence plant species and its distribution are those of the climatic factors and of the hydroedaphic factors. The organic substances are specially the key factors for the vegetation complexes in peatlands, and strongly affect many hydrogeochemical conditions ( e.g soil chemistry) Therefore, an investigation on the plant species from various types of mires and its components have been discussed in this paper. The study described here investigated the differences in chemical characteristics between peat deposits with different habitats and plant species
