Vegetation restoration in western Liaoning hilly region: A study based on succession theory and degradation degree of ecosystem

Abstract

Abstract: Based on the analysis of vegetation succession in western Liaoning hilly region,and by the method of Cluster Analysis with some habitat indexes of different succession stage,this paper quantitatively measured the degradation degree of degraded ecosystems in this region.The results showed that the average dissimilarities between natural Quercus forest,natural Chinese pine (Pinus tabulaeformis) forest and Populus-Quercus forest in Nanliuzhangzi forestry centre and Chinese pine plantations in Niuheliang region and Qitian forestry centre were 0.655,0.665,2.029 and 3.919,respectively,and as a whole,the dissimilarities represented the places of the forests in the process of ecosystem succession /degradation.It was also showed that most habitats were degraded to the stage between shrubbery and pioneer arbor forest,and closer to the succession stage of pioneer arbor forest.Some suggestions were made for the management of the existing plantation and the construction of mixed forest,e.g.,to increase the proportion of shrubbery and pioneer arbor species,especially that of nitrogen fixation tree species.The plant species list of several main vegetation types in western Liaoning we offered could provide scientific reference for the vegetation restoration and the management of pure Chinese pine plantation in this region.

Key words: Degraded ecosystem, Degradation degree, Succession theory, Vegetation restoration, Chinese pine, Western Liaoning Province
