Abstract

The monitoring studies of carbon transformation in different soil types of agroecosystems under aerotechnogenic contamination by heavy metals in years differing from the climatic norm are analyzed. The negative effects of changing environmental conditions on the content of microbial biomass and CO₂ emission in different soils have been evaluated experimentally. The ecophysiological parameters characterizing the availability of substrate and carbon (re)immobilization in soils show that the activity and stability of the microbial community depend on environmental changes. The methodology of system analysis of the intrasoil carbon cycle and the quantitative assessment of flows of net-mineralized and (re)immobilized carbon and their ratio were used for the first time for an integral assessment of the functioning regimes of agroecosystems and of the levels of the ecological load.

航空技术污染和气候变化下贝加尔湖地区不同类型土壤农业生态系统的碳转化

摘要

分析了不同气候常年大气技术污染下不同土壤类型农业生态系统碳转化的监测研究。环境条件变化对微生物生物量和 CO ₂含量的负面影响已通过实验评估了不同土壤中的排放。表征土壤中底物可用性和碳（再）固定化的生态生理参数表明，微生物群落的活性和稳定性取决于环境变化。土壤内碳循环的系统分析方法和净矿化和（再）固定化碳流量及其比率的定量评估首次用于对农业生态系统的功能机制和水平的综合评估。生态负荷。
