摘要

土壤有机碳（SOC）是生态系统稳定性和农业生产力的基础,充分了解焉耆盆地绿洲不同土壤类型SOC分布特征,对实现农业系统可持续发展具有重要意义。以新疆焉耆盆地绿洲长期定点试验的监测数据为基础,利用生物地球化学模型（DNDC）进行模拟试验,研究在当前的田间管理和气候模式下,焉耆盆地绿洲农田土壤有机碳密度（SOCD）和土壤有机碳储量（SOCS）的空间分布特征,并探究了在不同的土壤类型下SOCD和SOCS的差异性。结果表明:（1） DNDC模型能够很好的模拟该区域下SOC及其动态变化,模型相关系数（r）>92.75%,相对误差（E）介于2.98%~4.12%,<5%,模型的可靠性较高。（2） 2018年焉耆盆地绿洲农田0~20 cm SOCD介于12000~28000 kg·hm-2,SOCS为2414 Gg,不同区域之间的差异较为明显。（3） 不同的土壤类型之间,SOCD和SOCS差异明显,其中沼泽土的SOCD最大,为25136 kg·hm-2;石质土的SOCD最小,为13335 kg·hm-2。

Abstract

We investigated the density and spatial distribution of Yanqi basin oasis farmland soil organic carbon (SOC) among different soil types. Using long-term monitoring data from the Yanqi basin of the Xinjiang oasis area, we applied the DeNitrification-DeComposition (DNDC) model to conduct a simulated experiment. The results of the experiment showed that the DNDC model accurately simulated the SOC and its dynamic changes in this region, producing a correlation coefficient (r) higher than 92.75%. The relative error (E) was between 2.98% and 4.12%, indicating that the model has high reliability. In 2018, the SOC density in the 0-20 cm layer in the oasis area of Yanqi Basin was 12000-28000 kg·hm-2, and the total soil organic carbon reserves were 2414 Mg, with obvious differences among regions. Additionally, significant differences in SOC density and reserves were detected among soil types. The SOC density was highest in marsh soil at 25136 kg·hm-2 and lowest in stony soil at 13335 kg·hm-2. The implementation of specific field management measures for different regions and soil types is essential to restore the SOC cycle balance and facilitate the sustainable development of farmland in China.

Key words： oil organic carbon; DeNitrification-DeComposition model; Yanqi Oasis Basin; different soil types; organic carbon reserves; farmland soil
