Abstract

Analysis on the dynamic change of vegetation under different land use patterns can provide a reference for revegetation. In this study,the vegetation characteristics and the plant diversity under various land use patterns (such as the artificial enclosure zones,zones of returning farmland to forest or shrubbery and grass plots in forest) in Yanchi County,Ningxia Hui Autonomous Region during the period of 2010-2014 were analyzed by means of clustering analysis,Shannon-Wiener index,Simpson index,evenness index and richness index. Results are as follows: ① During the period of 2010-2014,the dominant species in three plots were compositae and leguminosae. The vegetation growth in the artificial enclosure zones,zones of returning farmland to forest or shrubbery and grass plots in forest was holistically poor; ② The change trend of vegetation diversity in three plots were similar. During the period of 2010-2014,the Shannon-Wiener index,evenness index and richness index were “M-shaped”. On the contrary,the Simpson index was “W-shaped”;③ In arid and semiarid regions,artificial fencing is still one of the effective measures of regenerating the degenerated grassland vegetation compared with the measure of returning farmland to forest or shrubbery and grass plots in forest.
