摘要

用便携式气体分析仪（CIRA S-1配备SRC-1呼吸室

PP System s

H itch in

UK）测量了古尔班通古特沙漠南缘阜康荒漠实验站（FS）柽柳丛和北沙窝（ND）梭梭林地冠下和冠间的土壤呼吸及土壤因子。分析表明：冠下和冠间的土壤理化性质存在明显的异质性

冠下土壤呼吸值高于冠间

FS林地的土壤有机质、电导率、全氮、碳酸钙等含量及土壤呼吸值都高于ND林地土壤。土壤呼吸与土壤CaCO3含量有明显的相关性

相关系数为0.89。土壤中CaCO3含量的空间变化对土壤呼吸值的时空变化有一定的影响。掌握土壤因子及土壤呼吸的空间变化

对了解荒漠生态系统过程、土壤微生物与有机质的相互作用及全球气候变化的研究都具有重要的意义。

Abstract

We measured soil respiration(SR) and soil characteristics under canopy and open land of Tamarix ramosissima Ledeb.in field station(FS) and Haloxylon ammodendron Bge.in north desert(ND)

southern of Gurbantunggtun desert

with an infrared gas analyzer system(model CIRAS-1

PP Systems

Hitchin

UK) equipped with a flow-through closed chamber.The results showed that heterogeneity of characteristics was different significantly between canopy and open land

soil respiration under canopy was higher than open land.In FS scrubland

the characteristics such as: SOM

CaCO_3 content were higher than ND as well as soil respiration.Relativity of soil respiration and CaCO_3 was marked;the changes of CaCO_3 content controlled the changes of soil respiration in temporal and spatial in scrubland.The objective of this study was to investigate spatial change of soil characteristics and soil respiration in scrubland

the changes were critical to understand the ecosystem process of desert

interaction between soil microbial and soil characteristics

study of global climate change.
