森林土壤碳储量调查评估技术研究

Research on Investigation and Assessment Techniques of Forest Soil Carbon Storage

在江西省域林地范围内,选择森林土壤调查与取样样地。在选定的固定样地外侧与样地森林类型相同的区域,按一定规则确定样点区,并在该区域内进行土壤调查取样。根据测定的土壤和枯落物数据,利用数理统计、数据库技术、GIS技术进行统计分析,掌握森林土壤碳储量及其分布状况。

In the range of forestland in Jiangxi Province, forest soil survey and sampling sites were selected. In the area which had the same forest type with sample plots outside of the selected fixed plot, the sampling plots were determined according to certain rules and soil sampling was conducted in this zone. Based on the measured soil and litter data,statistical analysis was conducted using mathematical statistics, database technology and GIS technology to understand the soil carbon storage and its distribution in the forest.
