摘要
通过对占马地小流域的调查分析研究,提出了针对珠江源头区的植被优化和重建恢复的6种模式,并在富源县的退耕还林和珠防工程中推广应用。占马地小流域通过植被优化和重建恢复后,林业收入明显增加,土壤侵蚀模数由1767 t/(km^2·a)下降为1087 t/(km^2·a),土壤侵蚀减少38.48%。
According to the study of Zhanmadi small watershed, 6 modes for vegetation improvement and reconstruction head of Pearl River were proposed. These modes were applied in Fuyuan county's conversion of arable land back to forest project and pearl river shelter forest project. Through the vegetation improvement and reconstruction , the income from the forest was obviously increased, the soil erosion modulus decreased from 1 767 t/(km^2 · a) to 1 087 t/(km^2 · a), the reduction rate was 38.48%.
