The IRGA(infrared gas analyzer) research methods were carried out to measure soil respiration and fine root respiration in three different complex ecosystems ((Betula luminifera+ Hemarthria compressa, Betula luminifer + Pleioblastus amarus, Betula luminifer) in converting farmlands to forest in Sichuan basin in Hong-Ya county (29°24′N, 102°49′E) in this article.
本研究采用动态密闭气室法(IRGA)对四川盆周西缘(眉山市洪雅县)三种主要退耕还林还草模式(模式1:光皮桦木+扁穗牛鞭草,模式2:光皮桦木+苦竹,模式3:光皮桦木+自然草)进行原位土壤呼吸和离体细根呼吸测量,并对土壤呼吸、细根呼吸呈现的时间、空间动态进行研究,分别从大气温度、土壤温度、土壤含水量、土壤理化性质、细根生物量、细根氮含量等方面与土壤呼吸、细根呼吸的动态变化进行相关性分析,深入研究在退耕还林地这一特殊的复合生态系统的生态过程,为退耕还林模式的可持续经营提供科学依据。
2) root respiration
根系呼吸
1.
Information on root respiration and biomass are important for understanding implications of environmental change on soil carbon cycling and sequestration.
依托FACE(Free-air CO2 enrichment)研究平台,利用特制分根集气生长箱,采用静态箱-GC(Gaschroma-tography)法,连续两年研究了大气CO2浓度升高和不同氮肥水平对冬小麦拔节期、孕穗抽穗期和灌浆末期的根系呼吸及生物量的影响。

Daily and seasonal variation of soil CO2 emission fluxes were measured using close chamber method in typical crop fields in Huang-huai-hai Plain, the impacts of soil temperature and moisture on soil CO2 emission flux were analyzed respectively, and the contribution of root respiration by using the DNDC ( DeNitrification – DeComposition ) model was also discussed.
施氮不仅影响土壤微生物的呼吸而且还影响到根系呼吸。
3.
In order to determine the possibility of measuring the root respiration by using root exclusion method,we conducted field experiments to measured total soil respiration and net soil respiration in three temperate grassland communities including Leymus chinensis free-grazed steppe,stipa grandis free-grazed steppe and Leymus chinensis degenerated free-grazed steppe in the growing season, 2005.
2005年生长季分别对内蒙古锡林河流域温带半干旱草原中的羊草自由放牧草原、大针茅自由放牧草原和羊草退化草原中的土壤总呼吸速率和去根土壤的呼吸速率进行了野外测定,初步探讨了在草地群落应用根去除法间接进行根系呼吸测定的可能性,并应用该方法对草地群落根系呼吸占土壤总呼吸的比例进行了估测。
