【摘要】：在全球變化與陸地生態(tài)系統(tǒng)關(guān)系的研究中,氣候和植被相關(guān)關(guān)系的研究具有非常重要的意義。本文以2014年內(nèi)蒙古草原生態(tài)系統(tǒng)定位站提供的氣象數(shù)據(jù)資料為基礎(chǔ),運用灰色相對關(guān)聯(lián)度以及含有時滯參數(shù)的灰色系統(tǒng)模型,分析了內(nèi)蒙古典型草原區(qū)域尺度黃囊苔草(Carex korshinskyi)地上生物量對6種氣象因子的響應(yīng)。結(jié)果表明:黃囊苔草對6種氣象因子的響應(yīng)均有滯后效應(yīng)。黃囊苔草地上生物量對降水量、氣溫、地溫、蒸發(fā)量、相對濕度、日照時數(shù)的響應(yīng)分別滯后10,16,16,10,15,5d。此結(jié)果將有助于更加深入理解氣象因子對植物群落的影響機制,并為草地植被生產(chǎn)力建模與定量預(yù)測提供信息基礎(chǔ),以期在實踐應(yīng)用中發(fā)揮更高的價值。
[Abstract]:In the study of the relationship between global change and terrestrial ecosystem, the study of the relationship between climate and vegetation is of great significance. Based on the meteorological data provided by Inner Mongolia grassland ecosystem Positioning Station in 2014, the grey system model with relative grey correlation degree and time-delay parameters is used in this paper. The response of aboveground biomass of Carex korshinskyi) to six meteorological factors in typical grassland of Inner Mongolia was analyzed. The results showed that the response of Carex sinensis to six meteorological factors had hysteresis effect. The response of biomass to precipitation, air temperature, soil temperature, evaporation, relative humidity and sunshine time on the grassland of Carex amurensis was 10 ~ 16 ~ 16 ~ 10 ~ 10 ~ 15 ~ 15 ~ 5 days, respectively. The results will be helpful to understand the influence mechanism of meteorological factors on plant communities, and provide information basis for modeling and quantitative prediction of grassland vegetation productivity, in order to play a higher value in practical application.
