本文在小流域综合治理试验研究基础上,根据影响林果树木成活和生长发育的主导因素,对河北省片麻岩山地划分了土地类型和小流域类型;采用系统工程的方法,通过微型计算机运算选择最优方案,研究了山地林果的合理布局、科学营造和管护,得出使生态效益和经济效益同步增长的生态经济系统工程模式。 Based on the experimental study on the comprehensive management of small watershed, based on the dominant factors that affect the survival and growth of trees and fruit trees, the paper divides the types of land and small watershed in the gneiss mountainous area of ​​Hebei Province. By using the method of system engineering, Choose the optimal plan, study the reasonable layout of mountainous forest fruit, build and manage scientifically, and draw the ecological and economic system engineering mode that makes the ecological and economic benefits increase synchronously.
