摘要
本文通过对四川盆地森林水文效应的研究,对长江上游防护林体系的生态环境作用进行了初步预测,并提出水源林、水土保持林的分区原则,以及防护林作用的累积效应,对长江上游防护林的规划和评价具有参考意义。
Based on research on forest hydrologic effect of Sichuan Basin,the ecologic environment effect of protective forest system at the upper reaches of Changjiang River is calculated. And then, the division principles for conservancy forest and shelter forest to protect the bead water are put forward and the cumulative effect of motective forest are dealt with. It should be of a reference value to plan and evaluation of protective forest at thd upper reaches of Changjiang River.
