摘要

增加陆地生态系统碳固定能力能有效缓解大气CO2升高引起的温室效应。以干旱区典型盐土和碱土为研究对象，通过室内土柱模拟试验，研究不同施用量脱硫石膏（0，10，20，21.78，30，40 t/hm2）对盐土和碱土生态系统碳储量（包括土壤碳储量和生物量碳储量）的影响。结果表明：与对照相比，施加脱硫石膏盐土总碳储量（C）降低8.78%~15.72%，其中以土壤有机碳储量降低为主；碱土总碳储量（C）增加5.00%~23.94%，其中以土壤无机碳增加为主。脱硫石膏施加后盐土总生物量碳储量（C）较对照平均降低23.14%，碱土总生物量碳储量（C）较对照平均增加30.44%。施用脱硫石膏碱土生态系统碳储量（C）较对照增加0.09~0.42 kg/m2，而盐土生态系统碳储量（C）较对照降低0.33~0.56 kg/m2。相关分析结果表明，脱硫石膏施加量、土壤电导率以及由脱硫石膏施加引起的土壤含水量变化是影响盐碱土生态系统固碳的主要因素。总体上，施加脱硫石膏后，盐土生态系统碳储量显著降低，碱土生态系统碳储量显著增加，其中施加量30，40 t/hm2处理对盐碱土生态系统碳储量影响效果最大。研究结果可为增加干旱区生态系统碳固定提供科学参考。

Abstract

The greenhouse effect induced by elevated CO2 can be alleviated by increasing capacity of carbon (C) sequestration in terrestrial ecosystems. Here

we carried out an indoor column simulation experiment with saline and sodic soils to assess the responses of ecosystem C stocks (including the C stock in soil and plant biomass) under the different amounts of flue gas desulfurization gypsum (FGDG) application (0

21.78

and 40 t/hm2). The results showed that:Compared with the control treatment

soil C stock decreased by 8.78%~15.72% in the saline soils as a result of the decrease in soil organic C stock. In contrast

soil C stock increased by 5.00%~23.94% in sodic soils with the application of FGDG largely derived from the increase of soil inorganic C stock. The C stock of wheat biomass decreased by 23.14% in saline soils and increased by 30.44% in sodic soils. The C stock of ecosystem increased by 0.09~0.42 kg/m2 in sodic soils and decreased by 0.33~0.56 kg/m2 in saline soils with the application of FGDG. These changes of C stock in the saline-sodic soils ecosystems were dominantly attributed to the amount of FGDG application

soil electrical conductivity

and the changes of water holding capacity caused by the application of FGDG. In a word

our study indicated that the C stock of ecosystems decreased in saline soils and increased in sodic soils

especially at the amount of 30 and 40 t/hm2 FGDG. This study will provide a scientific reference for increasing soil C sequestration in arid areas.
