Abstract

中国黄土高原北部の半乾燥地に位置する中国科学院西北水土保持研究所の神木試験地において,退耕還草地の中から25m<SUP>2</SUP>の調査区を50ヶ所設置して,植生調査を行い,土壌炭素・窒素及びFDA加水分解活性を測定し,微生物による有機物分解能力の把握を試みた。その結果,土壌炭素量・窒素量は植生量と正の相関関係にあり,FDA加水分解活性は土壌炭素量と高い正の相関関係にあった。したがって,微生物活性は植生の発達にともない高くなると考えた。FDA加水分解活性は土壌pHの上昇,土壌の硬化によって低下していた。

soil and vegetation surrey was conducted in 50 plots in Shenmu test area, which is located in the northern Loess Plateau. Floristic composition, plant biomass, soil carbon and nitrogen contents, and soil microbial activity were measured. Soil carbon and nitrogen contents had positive co-relationships with vegetation coverage. FDA hydrolysis activity had a close positive relationship with soil carbon contents. Consequently, microbial activity increased due to the development of vegetation. FDA hydrolysis activity declines in the plots of high pH and hardening of the soil.
