中国科学院红壤生态实验站长期监测研究进展

针对红壤地区面临的一系列土壤问题,中国科学院红壤生态实验站围绕典型红壤地区水、土、气、生4个方面的各项指标参数进行了长期监测。每年共采集和分析整理各类数据约30 Mb。大量的监测数据信息为红壤生态系统的长期研究以及区域农业可持续发展提供了支撑服务。通过多年的监测研究,发现红壤地区土壤p H呈下降趋势,土壤有机质、全量氮、磷等养分含量不同程度增加,土壤速效养分含量增长速度缓慢。

Progresses of Long-term Monitoring in Ecological Experiment Station of Red Soil, Chinese Academy of Sciences

For a series of problems in red soil, the indicator parameters of water, soil, meteorology and biology were monitored for a long time. Every year, the account of various types of analysis data was finished about 30 Mb. A large number of data provide support service for the long-term research and sustainable development of agriculture in red soil region. It showed soil pH decreased, the contents of soil total N, P and C increased, and the contents of soil available nutrients increased slowly.
