《森林资源动态预测模型》已通过技术鉴定。专家们在鉴定意见中评价说:这是一项很有意义的开创性工作,比日本铃木太七的研究成果有进一步发展。这一模型已经作为北京林业大学有关专业研究生的必修教材。郑冶刚工程师近几年来刻苦钻研,在攻克数学难关的基础上,研制成功这一模型,其成果固然可贺,然其精神更值得赞扬。由于篇幅所限,模型中的有关推导部分从略,有兴趣者,请看作者写的研究报告和有关文章。下期刊载第二部分。
The “Dynamic Prediction Model of Forest Resources” has passed the technical appraisal. Experts in the appraisal opinion commented: This is a very significant pioneering work, than Japan’s Suzuki too seven research results have further development. This model has been complied as a compulsory textbook for professional graduate students at Beijing Forestry University. In recent years, Zheng Yigang engineers study hard to overcome the math problems, based on the successful development of this model, the results are welcome, but its spirit deserves more praise. Due to space limitations, the derivation part of the model omitted, interested, please see the author’s research report and related articles. The next issue contains the second part.
