内蒙古锡林郭勒草地植物动态调查与统计分析方法探讨
Grassland Plants Dynamic Investigation and Statistical Analysis Technique Exploration of Xilingol in Inner Mongolia
【摘要】 基于中科院草原生态系统定位研究站的实时气象数据与实测植被数据,采用了单因子方差分析、多重比较和偏相关分析方法对羊草、针茅、冰草、苔草、冷蒿、羽茅、双齿葱7种植物的干重和高度的差异性及其与气温、地温、气压、水汽压、相对湿度、降水量、蒸发量、日照时数这8个气象因子的相关关系进行了统计分析。结果表明,不同植物在同一生长季内干重与高度对气象因子的响应存在差异;相同生活型植物在同一生长季内的生长动态相似;同一种植物的高度和干重对同一气象因子的相关性较为接近。而且,大多与该植物的生长习性相符合。
【Abstract】 The research is based on the real time meteorological data and vegetation data from Chinese Academy of Sciences Grassland Ecosystem Positioning Study Station, and uses single factor analysis of variance, multiple comparisons and partial correlation analysis.Statistical analysis is done to know the correlation between difference of dry weight and altitude of Chinese wildrye,stipa caplillata,wheatgrass,sedge,artemisia frigida,achnatherum sibiricum and bidentate onion,and 8 meteorological factors,including air temperature,ground temperature,air pressure,pressure of water vapor,relative humidity,precipitation,evaporation capacity and sunshine duration.There is difference in the response of dry weight and height of different plants in the same growth period to the meteorological factor.There is growth dynamic similarity of the same life form plants in the same growth period.The correlation between the dry weight and height of plants of the same plant with the same meteorological factor,and they are mostly accord with the vegetation characteristics.
