摘　　要：通过在甘肃和政县和定西县高山坡地实施林草结合的退耕还林还草试验研究,筛选出适合当地条件的林草复合植被的建植技术模式,表明在甘肃高山坡地建植林草复合植被,效益显著,是实现退耕还林还草目标和可持续发展战略的有效途径。Through experimental research on joint planting of trees and herbage to implement the return of cultivated land to forest and grass policy on alpine slopes in the Hezheng and Dingxi Counties of Gansu Province, the most suited establishment pattern for local conditions was screened out. The results indicate significant benefit for the establishment of combined grass and tree vegetation on alpine slopes in Gansu, and that this is an effective way to realize the goal of returning cultivated land to forest and grass and for sustainable development.
