森林土壤退化及其防治研究综述

Forest soil degradation research and preventive strategy: a review

介绍了土壤退化的概念;从树种生物学特性、人工林植物群落结构和栽培措施方面探讨了森林土壤退化的机理;提出了防治森林土壤退化的对策。文章最后指出,应从多学科的角度深入系统地研究地力衰退的机理,利用遥感、地理信息系统等高新技术手段构建包括计算机模拟模型、林地指南、关键决策系统、专家系统等在内的不同的预测和决策工具,同时加强天然林的进一步研究。

The conceptions of forest soil degradation and present achievement in forest soil degradation research and preventive strategies in China and other countries in recent years were reviewed. The mechanisms of forest soil degradation were discussed from various aspects including the biological characteristic of tree species and the cultivation methods. It revealed that the management experiences, biological measures, and fertilizer and municipal sludge applications were effective to prevent forest soil degradation. Finally, the further research work needed in the field was put forward, including research in 1) the declining mechanism thoroughly and with multi-discipline, 2) using advanced technologies to establish various forecast and decision tools including computer simulation model, woodland manual, key decision-making system, and specialist system. Research in the natural forests needed to be strengthened at the same time.
