摘  要：
笔者于2014年7月-8月,以大庆市行政管辖区的草地为对象,采用样地调查方法,对草地群落密度、盖度、地上生物量数量特征进行调查,并计算Patrick丰富度指数、Shannon-Wiener多样性指数、Pielou均匀度指数。结果表明,研究区草地群落Patrick丰富度指数为3.84~7.64,Shannon-Wiener多样性指数为0.93~1.36,Pielou均匀度指数为0.64~0.73;草地群落的Patrick丰富度指数、Shannon-Wiener多样性指数均为北部和中部区域高于南部区域,Pielou均匀度指数则为南部和北部区域高于中部区域。

摘  要：
The investigation of grassland was conducted in administrative jurisdiction of Daqing City municipality from July to August in2014. With sample plot method, the quantitative characteristics of grassland community from density, coverage and aboveground biomass were observed in the study area. Then, calculate the Patrick richness index, Shannon-Wiener diversity index and Pielou evenness index. The results showed that the study area grassland community of Patrick richness index, Shannon-Wiener diversity index,Pielou evenness index were 3.84~7.64, 0.93~1.36, 0.64~0.73, respectively. Both Patrick richness index and Shannon-Wiener diversity index of the grassland community were showed that the region of the north and centre were higher than the south. Pielou evenness index showed that the region of the south and north were higher than the centre.
