A total of 384 forest soils samples at 0-5cm depth collected from 8 forest site zones (13 Natural Reserves) in China were examined for the distribution of Bacillus and Bacillus thuringiensis. The 79 cultures (4.21%) in 1873 isolates of Bacillus collected referable to the Bacillus thuringiensis. Soil pH, moisture content and soil nutrient were determined. Rules of the ecological distribution of Bacillus thuringiensis of 8 forest site zones in China were analysed. Toxicities against 6 species of insect were tested. Strain some efficient serains were obtained. It was shown that resource of Bacillus thuringiensis is much fruitful in forest soils of China.
对从中国8个森林地带（13个自然保护区）采集的384份0-5厘米深度的森林土壤样本进行了芽孢杆菌和苏云金芽孢杆菌分布情况的检测。在收集的1873株芽孢杆菌分离株中，有79株培养物（4.21%）可鉴定为苏云金芽孢杆菌。测定了土壤pH值、含水量和土壤养分。分析了中国8个森林地带苏云金芽孢杆菌的生态分布规律。测试了对6种昆虫的毒性。获得了一些高效菌株。结果表明，中国森林土壤中苏云金芽孢杆菌资源十分丰富。
