Ecological environment had a great effect on litter decomposition. Decomposition rate was different in different ecological environments. For example,the decompositions of Le.y-mus chinensis litter in six habitats were obviously different. Decomposition rates were different in earth's surface and inunderground and litter in underground was decomposed faster than on earth's surface. Decomposition rate was linked, with ecological factors closely. Decomposition rate presented positively exponential relation wi...
